The Gargantuan Fossil
This post was from the beginning of my project, thus some information I’ve written here is outdated. Please read my recent posts to see up to date information.
The Gargantuan Fossil is one of the most recognizable parts of the mid-portion of Subnautica’s gameplay. Its sheer size strikes both terror and awe into the hearts of players who stumble upon it. It’s unfortunate that only a third of the creature’s fossilized remains can be seen. Even using the Freecam command to check under the map reveals that the rest of the skeleton remains unmodeled. This is all we have of the Leviathan.
Tumblr media
“Gargantuan Fossil” is quite the accurate name, considering just a third of this creature’s skeleton measures 402 meters in length, with the creature’s total size being an estimated 1,100-1,500 meters. Just the skull itself is under 100 meters, and our human player character can nestle comfortably in even its smallest eye socket. I would’ve tried to show our human character’s model for a size comparison, but this thing is so large you wouldn’t even be able to see him.
There have been many different reconstructions of this behemoth of a fossil, the most popular being this commission piece made by Tapwing, for the YouTuber Anthomnia, shown below. And while it’s cool, it’s... not all that accurate.
Tumblr media
In the past, I actually helped create a Gargantuan Leviathan mod based off Tapwing’s concept, working alongside other incredibly talented artists (who will remain anonymous, they can talk about their experiences as they please) and some... not so savory individuals. I don’t want to be associated with that old Garg. This reconstruction project is both a way for me to move on and make something better than what I had in the past, and to test my skills and knowledge in the various natural sciences.
Although there is a second specimen, the skull of a younger instance, this fossil holds no significant data outside of showing just how small these creatures start out as. As shown in the image below, despite being a much younger instance, our player character could still fit inside the Leviathan’s smallest eye socket, although it wouldn’t be as spacious as its adult counterpart.
Tumblr media
The game’s PDA (Personal Data Assistant) states that the Gargantuan Fossil is approximately 3 million years old, which is INCREDIBLY RECENT. For reference, 3 million years ago we still shared the planet with multiple other hominid species like Australopithecus afarensis back in the mid Pliocene. The Subnautica we know today is a byproduct of a mass-extinction of megafauna, such as Leviathans. My guess as to how the Gargantuan got this big is a combination of deep-sea gigantism and an evolutionary arms race against the other megafauna alive during its time, with prey attempting to become larger than its predator to avoid predation, and the predator growing to continue this cycle. When this ancient ecosystem of leviathan-class super predators collapsed, likely because of the meteor that struck Planet 4546B, the Gargantuan Leviathan was out of a substantial food source and went extinct. It could be possible that these creatures even gave live birth due to their serpentine body and massive size, making them too large for life in the shallows, where laying eggs is easiest.
NOW. LET’S TALK ABOUT THE BONES!! It’s important to figure out if the Gargantuan Leviathan had a cartilaginous skeleton or a bony one, so let’s count the bones!!
Tumblr media
There’s TWO WHOLE BONES!!! AND IF YOU LOOK NEXT TO IT!! THOSE RIBS ARE BONES TOO!!!! UWAA!!! SO MANY BONES!!!! How can we tell this is bones? It’s simple! Cartilage is rubbery and flexible, so it doesn't fossilize well, while bone is hard and rigid, perfect fossil material!! Cartilaginous skulls also tend to be made up of many little interlocking bones, with bony skulls being made up of only a small handful! 
Tumblr media
Another thing I found interesting about the Gargantuan Skull is that it seems to have a ball and socket joint? This could have just been a similar mishap to the top and bottom jaws being fused in the skull’s model, but I’m trying to keep things as close to the original anatomy as possible. The ball and socket joint probably evolved to help with the burden of such a massive and heavy skull and allowing for greater speed and range of motion. In a world full of Leviathan-class predators, being able to have a wide range of motion would be extremely beneficial in locating both potential predators and prey.
Tumblr media
Despite its immense size pushing the claim this Leviathan was an apex predator, it sports a small pair of horns, which is unheard of in large apex predators here on Earth. The darker coloration leads me to believe that these aren’t just horn cores, but the entire horn. These horns were most likely used to assist in defending itself against predators while it’s still small and vulnerable. It could also be a possibility they were used for threat displays and territory fights though it seems unlikely due to their small size. Sexual displays are also unlikely since just about every creature in Subnautica seems capable of asexual reproduction, as noted in the PDA entry for eggs. Asexual reproduction seems to be a very ancient basal trait in Planet 4546B’s evolutionary lineage and was most likely evolved to help species persevere even with low numbers and harsh conditions, preventing the dangers of inbreeding.
Tumblr media
Overall, the skull’s shape and tooth structure suggest a piscivorous diet (of course it eats fish, the planet’s 99% water), and its shape specifically is reminiscent of an Orca and Redondasaurus. The lack of nostrils stumps me, there’s no openings in the skull aside from its eye sockets, however there’s also no evidence for a gill apparatus. I’m... going to have to come back to that at a later date. Though I personally believe the Gargantuan Leviathan was an air breather due to the lack of evidence for gills.
OKOK, ENOUGH ABOUT THE SKULL ASRIEL, WHAT ABOUT THE RIBS?
Tumblr media
WELL... THE RIBS ARE... SOMETHING.
Tumblr media Tumblr media
Behold! My very poor photomash of the same two images to show the total approximate length of the Gargantuan Leviathan, and a bad edit to show off what I believe the whole skeletal system would look like! (skeleton image credit)
Despite the game’s PDA describing the Gargantuan Leviathan’s body as “eel-like,” its skeletal structure is more reminiscent of a snake. The ribs show no indication of limbs, so it probably had a dorsal fin similar to eels or sea kraits.
Tumblr media
One thing I’ve noticed about the Gargantuan’s ribcage is the existence of what appear to be bony, avian-like uncinate processes, which help the trunk’s muscles pump in and air out of the body, adding onto the idea that this leviathan breathed air. These uncinate processes in diving birds are especially long, which help reinforce the body and musculature, allowing the animal to stay underwater for longer periods of time.
My hypothesis for the role the Gargantuan Leviathan played in its ecosystem is similar to the Sperm Whales of our world, taking in large amounts of air before diving into the depths to fetch their food.
Next week, I’ll be doing more research into the skeleton and possibly beginning work on fleshing the Garg out! If there are any sciencey folks out on Tumblr who want to add their own input, feel free!! I want information!! Correct me if I got anything wrong!!

“There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.” Carl Sagan
Ecoinvent, the world’s largest database on the environmental impact of wind and solar technologies, has no data from China, even though it makes most of the world's solar panels
The UN IPCC and IEA have relied on Ecoinvent estimates of life cycle CO2 emissions from solar, but given China refuses to be transparent in their reporting, Ecoinvent fudged the numbers using values from EU and US manufacturing.
As a result, Chinese derived solar PV panels have life cycles in the range of 170 to 250 kg CO2 equivalent per MWh versus the 50 kg CO2 per MWh so commonly used by the IPCC and others in calculating CO2 emission offset credits and in climate modelling.
Consider that advanced combined cycle gas turbine power plants have CO2 emission factors ranging from 300 to 350 kg CO2 per MWh and use a much smaller fraction of the amount of non-renewable materials per unit of energy produced than do solar PV facilities.
It is a well known fact that paring natural gas turbine technologies in a load balancing subservient role to solar PV gives rise to reduced thermal efficiencies of the turbine system. Thereby acting to further reduce the emission reduction benefits of solar PV and its already small marginal difference with a stand alone natural gas system.
The moral of the story is carbon credits are a scam, as are modelling projections of the climate effects of solar PV technologies.

Oceans of water found on Mars
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water — enough to fill oceans on the planet's surface.
The data from NASA's Insight lander allowed the scientists to estimate that the amount of groundwater could cover the entire planet to a depth of between 1 and 2 kilometers, or about a mile.
While that’s good news for those tracking the fate of water on the planet after its oceans disappeared more than 3 billion years ago, the reservoir won't be of much use to anyone trying to tap into it to supply a future Mars colony. It's located in tiny cracks and pores in rock in the middle of the Martian crust, between 11.5 and 20 kilometers below the surface. Even on Earth, drilling a hole a kilometer deep is a challenge.
The finding does pinpoint another promising place to look for life on Mars, however, if the reservoir can be accessed. For the moment, it helps answer questions about the geological history of the planet.
“Understanding the Martian water cycle is critical for understanding the evolution of the climate, surface and interior,” said Vashan Wright, a former UC Berkeley postdoctoral fellow who is now an assistant professor at UC San Diego’s Scripps Institution of Oceanography. “A useful starting point is to identify where water is and how much is there.”
Wright, alongside colleagues Michael Manga of UC Berkeley and Matthias Morzfeld of Scripps Oceanography, detailed their analysis in a paper that will appear this week in the journal Proceedings of the National Academy of Sciences.
The scientists employed a mathematical model of rock physics, identical to models used on Earth to map underground aquifers and oil fields, to conclude that the seismic data from Insight are best explained by a deep layer of fractured igneous rock saturated with liquid water. Igneous rocks are cooled hot magma, like the granite of the Sierra Nevada.
"Establishing that there is a big reservoir of liquid water provides some window into what the climate was like or could be like," said Manga, a UC Berkeley professor of earth and planetary science. "And water is necessary for life as we know it. I don't see why [the underground reservoir] is not a habitable environment. It's certainly true on Earth — deep, deep mines host life, the bottom of the ocean hosts life. We haven't found any evidence for life on Mars, but at least we have identified a place that should, in principle, be able to sustain life."
Manga was Wright's postdoctoral adviser. Morzfeld was a former postdoctoral fellow in UC Berkeley’s mathematics department and is now an associate professor of geophysics at Scripps Oceanography.
Manga noted that lots of evidence — river channels, deltas and lake deposits, as well as water-altered rock — supports the hypothesis that water once flowed on the planet's surface. But that wet period ended more than 3 billion years ago, after Mars lost its atmosphere. Planetary scientists on Earth have sent many probes and landers to the planet to find out what happened to that water — the water frozen in Mars' polar ice caps can't account for it all — as well as when it happened, and whether life exists or used to exist on the planet.
The new findings are an indication that much of the water did not escape into space but filtered down into the crust.
The Insight lander was sent by NASA to Mars in 2018 to investigate the crust, mantle, core and atmosphere, and it recorded invaluable information about Mars' interior before the mission ended in 2022.
"The mission greatly exceeded my expectations," Manga said. "From looking at all the seismic data that Insight collected, they've figured out the thickness of the crust, the depth of the core, the composition of the core, even a little bit about the temperature within the mantle."
Insight detected Mars quakes up to about a magnitude of 5, meteor impacts and rumblings from volcanic areas, all of which produced seismic waves that allowed geophysicists to probe the interior.
An earlier paper reported that above a depth of about 5 kilometers, the upper crust did not contain water ice, as Manga and others suspected. That may mean that there's little accessible frozen groundwater outside the polar regions.
The new paper analyzed the deeper crust and concluded that the "available data are best explained by a water-saturated mid-crust" below Insight’s location. Assuming the crust is similar throughout the planet, the team argued, there should be more water in this mid-crust zone than the "volumes proposed to have filled hypothesized ancient Martian oceans."
IMAGE: A cutout of the Martian interior beneath NASA's Insight lander. The top 5 kilometers of the crust appear to be dry, but a new study provides evidence for a zone of fractured rock 11.5-20 km below the surface that is full of liquid water — more than the volume proposed to have filled hypothesized ancient Martian oceans.

Reading List: Spirituality, Globalisation, Parenting and the 0.99 Cent Pricing Bias
What I’ve read (🖤) and planning to read (🤍)
Books
• Fall of human intellect - A Parvasarthy (genre: spirituality, humanness) 🖤
Academic Papers
The backlash against globalisation - Stefanie Walter (from annual review) 🤍
In recent years, the world has seen a rising backlash against globalization. This article reviews the nature, causes, and consequences of the globalization backlash. It shows that, contrary to a popular narrative, the backlash is not associated with a large swing in public opinion against globalization but is rather a result of its politicization. The increasing influence of globalization- skeptic actors has resulted in more protectionist, isolationist, and nationalist policies, some of which fundamentally threaten pillars of the contemporary international order. Both material and nonmaterial causes drive the glob- alization backlash, and these causes interact and mediate each other. The consequences are shaped by the responses of societal actors, national gov- ernments, and international policy makers. These responses can either yield to and reinforce the global backlash or push back against it. Understanding these dynamics will be an important task for future research.
The causes and consequences of urban riot and unrest - Tim Newburn (from annual review) 🤍
This review explores those varied bodies of work that have sought to un- derstand crowd behavior and violent crowd conduct in particular. Although the study of such collective conduct was once considered central to social science, this has long ceased to be the case and in many respects the study of protest and riot now receives relatively little attention, especially within criminology. In addition to offering a critical overview of work in this field, this review argues in favor of an expanded conception of its subject matter. In recent times, scholarly concern has increasingly been focused on ques- tions of etiology, i.e., asking how and why events such as riots occur, with the consequence that less attention is paid to other, arguably equally impor- tant questions, including how riots spread, how they end, and, critically, what happens in their aftermath. Accordingly, as a corrective, the review proposes a life cycle model of riots.
Parenting and it’s effects on children : reading and misreading behaviour genetics (from annual review) 🖤
There is clear evidence that parents can and do influence children. There is equally clear evidence that children’s genetic makeup affects their own behavioral characteristics, and also influences the way they are treated by their parents. Twin and adoption studies provide a sound basis for estimating the strength of genetic effects, although heritability estimates for a given trait vary widely across samples, and no one estimate can be considered definitive. This chapter argues that knowing only the strength of genetic factors, however, is not a sufficient basis for estimating environmental ones and indeed, that attempts to do so can systematically underestimate parenting effects. Children’s genetic predispositions and their parents’ childrearing regimes are seen to be closely interwoven, and the ways in which they function jointly to affect children’s development are explored.
More than a penny’s worth: left-digit bias and firm pricing- Avner Strulov-Shlain (from MorningBrew) 🤍
A penny saved. What’s the difference between $2.99 and $3.00? Basic math says one cent, but you probably perceive the difference to be about 22 cents, a new paper by a University of Chicago business school professor estimated. The research explores left digit bias—the phenomenon where consumers’ perceptions are overly influenced by the leftmost number in the price—and it brought receipts, analyzing retail scanner data on 3,500 products sold by 25 US chains. And while it might seem like every price you see ends in .99, the paper argues that retailers are leaving money on the table by underestimating this bias when setting prices.

Space Suits - Then and Now
Since the dawn of the space age on Reyal, it became abundantly clear that there were many challenges they'd have to face.
As a social species, they struggle with solitude; the first few missions were a nightmare, as the panic from being detached from friends and family became a big issue. However, that was manageable with therapy and much shorter solo missions.
Radiation was a much more pressing issue, and after the long-term health affects became clear from the relative lack of protection, major steps were taken to build suits that would withstand the harsh environs of space.
Reyal is a very unique world, in that its thick atmosphere and highly active core provided much more shielding from cosmic and solar radiation than our own Earth would. This led to pretty much every life form on Reyal being much more susceptible to radiation's harmful effects, which would prove to be a very difficult roadblock on their technological voyage.
There was much discussion as what type of suit would be better after regular flight suits were proven to be ineffective; hardshell, which was heavy and hard to maneuver in but gave incredible protection, or soft shell, which was a tiny bit easier to work in, but offered barely any protection.
After some research and development, a mix was approved for use; soft around the joints, with most of the rest of the body being hardshell. It wasn't ideal, but there was very little else that can be done to combat the lack of mobility.
Tumblr media
Art by @bjekkergauken After years of development, hard work, and testing, the first deep space suits were approved for regular use. The above is a display model; showing heraldry only for the Global Resource Committee's Space Division, and crampons for a rocky or icy moon.
These used many new technologies and techniques to help protect the wearer, such as a camera based vision system. This not only helps protect the eyes, but can allow for a better understanding of the environment around the wearer, being able to cycle into different types of light wavelengths.
Some other useful features are the claw grabbers that replace the gloves, allowing for much easier mobility in the vacuum. Initial testing proved that softshell gloves were a nightmare to work with, causing many engineers to nearly quit out of frustration. A few late night brainstorming sessions later, they figured out that using a manipulator was much easier than anything else. This would become a mainstay for future suit design, and open up a massive world of possibilities for on-orbit construction and more.
Aside from that, the suit also boasts a data pad for easy communication & lookup, a jetpack for low-or-no gravity environments (fueled by pure nitrogen), and a hatchback for hooking up into vehicles for easy doffing and donning.
These suits were used en masse for many years, in a massive variety of situations; from low Reyal orbit and all the way out to Alkan and her twin, they saw very heavy use for the first few decades of the Lyratet's expansion into space.
However, as their needs expanded, the old generation of suits would prove to need an upgrade. Cameras failing while out, data pads falling off, life support issues, outdated technology, and more would be the sign that things had to change.
Tumblr media
Art by @hellagator Five years before the launch of the First Extended Thrallit Expedition, the Global Resource Committee finally approved and released the latest design; the Modular Deep Space Maneuvering Unit, or the MDSMU for short. This would be a massive upgrade from the previous design, making up for most of its shortfalls.
With advances in material science and a better understanding of life and work in space, the MDSMU sported much better mobility, all without sacrificing any radiation protection. A thin layer of a lead alloy, alongside water ice, was added to help aid in deflecting any harmful radiation. Aside from this, most everything is the same.
The same applies for the new and improved helmet, which allows for both regular vision, alongside the original camera vision. The visor is made of a heavy layer of leaded titanium glass on the outside, followed by a thin layer of water ice, and finally a quantum dot display on the inside. While it's just as safe to use regular vision these days, many still opt to cover up the outside, and use only the camera.
Another major advancement is the modular ability of the suit; while the previous design was used in a variety of situations, it wasn't very practical for exploration out past Alkan, or in the inner system past Reyal. The suit has dozens of other parts that can be swapped out or added, ranging from underwater maneuvering addons for Alkan, to an extended heating system for cave diving on Lejag, the outermost planet.
The suit can also be very easily modified to suit any changes to the wearer’s body, or in a swapping of people wearing it, thanks to machine learning and a complex system of elastic and memory foam. The only thing that doesn't change is the horn armor; GRCSED standards have them set to a certain height, mainly for ease of access among their many bases and outposts, and the dangers that come with overgrowth.
The only thing that would change would be the fuel used over the centuries; originally, monomethylhydrazine was used for fuel as an improvement upon just raw nitrogen. However, as some spills occurred in a few bases, it was quickly replaced with nitrogen once more due to the toxicity of the prior.
This suit design would be the last they would ever design, as the base was very easy to modify for practically any situation. From routine maintenance on Ro, all the way to the interstellar colony of Reyal-Lontag, the suit would see continued use until the end of civilization as we know it.

Researchers call it the “sea cow effect”: To save the kelp forests, read history
In findings published today in Frontiers in Ecology and Evolution, scientists from the California Academy of Sciences describe how one unassuming undulator, the Stellar’s sea cow, affected the kelp forests ringing North America’s Pacific coast before European visitors hunted it to extinction in the 1760s.
According to the authors, our tendency to assess ecosystems based on current and recent factors, which they call shifting baseline syndrome, may prevent us from seeing the big picture. Ecologically speaking, the sea cows were around until relatively recently, but because “relatively” here means “before scientific method came into its own,” they’ve been left out of most model.s
Much like how beavers create openings in the terrestrial canopy by damming streams to create lakes, the sea cow’s mighty megaherbivory cleared away the upper fronds of the kelp forests, allowing shafts of sunlight to pass through the otherwise photon-thirsty upper kelp into the marine understory and smaller plants, most significantly algae. The algae in turn provided food for other organisms.
Over the past few decades, California’s kelp forests have been dying off. Sea urchins have thrived in the area’s warming waters and have devoured the kelp plants, creating desolate stretches called urchin barrens. This may be due to human overhunting of their principal predators—sea otters. But unlike the Stellar’s sea cow, sea otters survived the European onslaught until the advent of protective legislation and are now in recovery. In efforts to save the kelp forests, researchers usually remembered sea otters but forgot the sea cows.
“When kelp forests were evolving millions of years ago, there were large marine herbivores like the Steller’s sea cow, which are now extinct,” says study co-author Dr. Peter Roopnarine. “So when it comes to what’s driving their widespread decline, there might be a major component we’re missing.” Roopnarine went on to compare the sea cows to terrestrial wildfires. Human beings might think they’re helping the forests by putting them out, but they’re actually a necessary and natural part of its life cycle.
Roopnarine and co-authors proposed a new model: the Past-Present-Future approach (PPF). This model incorporates what we think of as modern scientific data, museum samples, and ecological knowledge from traditional Indigenous sources.
The research team built a mathematical model of a kelp forest using data about sea urchins, sea otters, and other extant factors and then added the sea cows. According to study co-author Dr. Roxanne Banker of the University of Nevada, this transformed the forest completely. Their findings suggested that before about 1750, the kelp forests would have been better described as kelp-and-algae forests. With the sea cows clearing the upper layers of kelp away, algae would have dominated the middle levels.
This kelp-algae ecosystem would have been much more resilient to such challenges as drastic changes in temperature or hordes of oncoming urchins. Urchins, Banker points out, like to eat algae, and their voracious appetite for kelp may have been caused by the disappearance of this other food source. The researchers call this the “sea cow effect”: Even though, intuitively, it might seem like removing the large herbivores would help the kelp, it seems to have hurt them and every other organism nearby.
Roopnarine hypothesizes that sending human beings out to trim the kelp fronds might be produce something similar to this older, healthier kelp ecosystem.

Stages of the Data Science Life Cycle
Tumblr media
The Data Science Life Cycle is a systematic process that guides data scientists in turning raw data into meaningful insights. Each stage of the life cycle plays a crucial role in ensuring the success of a data science project. 
This guide will walk you through each stage, from understanding the business problem to communicating the results effectively. By following these stages, you can streamline your approach and ensure that your data science projects are aligned with business goals and deliver actionable outcomes.
Business Understanding
The first stage of the Data Science Life Cycle is Business Understanding. It involves identifying the problem or business objective that needs to be addressed. 
This stage is critical because it sets the direction for the entire project. Without a clear understanding of the business problem, data science efforts may be misaligned, leading to wasted resources and suboptimal results.
To begin, you must collaborate closely with stakeholders to define the problem or objective clearly. Ask questions like, "What is the business trying to achieve?" and "What are the pain points that data science can address?" 
This helps in framing the data science goals that align with the broader business goals. Once the problem is well-defined, you can translate it into data science objectives, which guide the subsequent stages of the life cycle.
Data Collection
With a clear understanding of the business problem, the next step is Data Collection. In this stage, you gather relevant data from various sources that will help address the business objective. Data can come from multiple channels, such as databases, APIs, sensors, social media, and more.
Understanding the types of data available is crucial. Data can be structured, such as spreadsheets and databases, or unstructured, such as text, images, and videos. 
Additionally, you must be aware of the formats in which data is stored, as this will impact how you process and analyze it later. The quality and relevance of the data you collect are paramount, as poor data quality can lead to inaccurate insights and faulty decision-making.
Data Preparation
Once you have gathered the data, the next stage is Data Preparation. This stage involves cleaning and preprocessing the data to ensure it is ready for analysis. 
Data cleaning addresses issues such as missing data, outliers, and anomalies that could skew the analysis. Preprocessing may involve normalizing data, encoding categorical variables, and transforming data into a format suitable for modeling.
Handling missing data is one of the critical tasks in this stage. You might choose to impute missing values, drop incomplete records, or use algorithms that can handle missing data. 
Additionally, outliers and anomalies need to be identified and addressed, as they can distort the results. Data transformation and feature engineering are also part of this stage, where you create new features or modify existing ones to better capture the underlying patterns in the data.
Data Exploration and Analysis
Data Exploration and Analysis is where you begin to uncover the insights hidden within the data. This stage involves conducting exploratory data analysis (EDA) to identify patterns, correlations, and trends. EDA is an essential step because it helps you understand the data's structure and relationships before applying any modeling techniques.
During this stage, you might use various tools and techniques for data visualization, such as histograms, scatter plots, and heatmaps, to explore the data. These visualizations can reveal important insights, such as the distribution of variables, correlations between features, and potential areas for further investigation. 
EDA also helps in identifying any remaining issues in the data, such as biases or imbalances, which need to be addressed before moving on to the modeling stage.
Data Modeling
After exploring the data, the next stage is Data Modeling. This stage involves selecting appropriate algorithms and models that can help solve the business problem. The choice of model depends on the nature of the data and the specific problem you are trying to address, whether it's classification, regression, clustering, or another type of analysis.
Once you've selected the model, you'll train it on your data, testing different configurations and parameters to optimize performance. After training, it's crucial to evaluate the model's performance using metrics such as accuracy, precision, recall, and F1 score. This evaluation helps determine whether the model is robust and reliable enough for deployment.
Model Deployment
With a well-trained model in hand, the next step is Model Deployment. In this stage, you deploy the model into a production environment where it can start generating predictions and insights in real-time. Deployment may involve integrating the model with existing systems or setting up a new infrastructure to support it.
Continuous monitoring and maintenance of the model are vital to ensure it remains effective over time. Models can degrade due to changes in data patterns or shifts in business needs, so regular updates and retraining may be necessary. Addressing these issues promptly ensures that the model continues to deliver accurate and relevant results.
Communication of Results
The final stage of the Data Science Life Cycle is Communication of Results. Once the model is deployed and generating insights, it's essential to communicate these findings to stakeholders effectively. Visualization plays a key role in this stage, as it helps translate complex data into understandable insights.
You should present the results clearly, highlighting the key findings and their implications for the business. Creating actionable recommendations based on these insights is crucial for driving decision-making and ensuring that the data science project delivers tangible value.
Challenges in the Data Science Life Cycle
In the Data Science Life Cycle, challenges are inevitable and can arise at every stage. These obstacles can hinder progress if not addressed effectively. However, by recognizing common issues and implementing strategies to overcome them, you can ensure a smoother process and successful project outcomes.

NASA’s PACE satellite’s Ocean Color Instrument (OCI) detects light across a hyperspectral range, which gives scientists new information to differentiate communities of phytoplankton – a unique ability of NASA’s newest Earth-observing satellite. This first image released from OCI identifies two different communities of these microscopic marine organisms in the ocean off the coast of South Africa on Feb. 28, 2024. The central panel of this image shows Synechococcus in pink and picoeukaryotes in green. The left panel of this image shows a natural color view of the ocean, and the right panel displays the concentration of chlorophyll-a, a photosynthetic pigment used to identify the presence of phytoplankton.
NASA is now publicly distributing science-quality data from its newest Earth-observing satellite, providing first-of-their-kind measurements of ocean health, air quality, and the effects of a changing climate.
The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite was launched on Feb. 8, and has been put through several weeks of in-orbit testing of the spacecraft and instruments to ensure proper functioning and data quality. The mission is gathering data that the public now can access at https://pace.oceansciences.org/access_pace_data.htm.
PACE data will allow researchers to study microscopic life in the ocean and particles in the air, advancing the understanding of issues including fisheries health, harmful algal blooms, air pollution, and wildfire smoke. With PACE, scientists also can investigate how the ocean and atmosphere interact with each other and are affected by a changing climate.  
“These stunning images are furthering NASA’s commitment to protect our home planet,” said NASA Administrator Bill Nelson. “PACE’s observations will give us a better understanding of how our oceans and waterways, and the tiny organisms that call them home, impact Earth. From coastal communities to fisheries, NASA is gathering critical climate data for all people.”
“First light from the PACE mission is a major milestone in our ongoing efforts to better understand our changing planet. Earth is a water planet, and yet we know more about the surface of the moon than we do our own oceans. PACE is one of several key missions – including SWOT and our upcoming NISAR mission – that are opening a new age of Earth science,” said Karen St. Germain, NASA Earth Science Division director.  
PACE’s OCI instrument also collects data that can be used to study atmospheric conditions. The top three panels of this OCI image depicting dust from Northern Africa carried into the Mediterranean Sea, show data that scientists have been able to collect in the past using satellite instruments – true color images, aerosol optical depth, and the UV aerosol index. The bottom two images visualize novel pieces of data that will help scientists create more accurate climate models. Single-Scattering Albedo (SSA) tells the fraction of light scattered or absorbed, which will be used to improve climate models. Aerosol Layer Height tells how low to the ground or high in the atmosphere aerosols are, which aids in understanding air quality.
Credit: NASA/UMBC
The satellite’s Ocean Color Instrument, which was built and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, observes the ocean, land, and atmosphere across a spectrum of ultraviolet, visible, and near infrared light. While previous ocean color satellites could only detect a handful of wavelengths, PACE is detecting more than 200 wavelengths. With this extensive spectral range, scientists can identify specific communities of phytoplankton. Different species play different roles in the ecosystem and carbon cycle — most are benign, but some are harmful to human health — so distinguishing phytoplankton communities is a key mission of the satellite.
PACE’s two multi-angle polarimeters, HARP2 and SPEXone, measure polarized light that has reflected off clouds and tiny particles in the atmosphere. These particles, known as aerosols, can range from dust to smoke to sea spray and more. The two polarimeters are complementary in their capabilities. SPEXone, built at the Netherlands Institute for Space Research (SRON) and Airbus Netherlands B.V., will view Earth in hyperspectral resolution – detecting all the colors of the rainbow – at five different viewing angles. HARP2, built at the University of Maryland, Baltimore County (UMBC), will observe four wavelengths of light, with 60 different viewing angles.
Early data from the SPEXone polarimeter instrument aboard PACE show aerosols in a diagonal swath over Japan on Mar. 16, 2024, and Ethiopia on Mar. 6, 2024. In the top two panels, lighter colors represent a higher fraction of polarized light. In the bottom panels, SPEXone data has been used to differentiate between fine aerosols, like smoke, and coarse aerosols, like dust and sea spray. SPEXone data can also measure how much aerosols are absorbing light from the Sun. Above Ethiopia, the data show mostly fine particles absorbing sunlight, which is typical for smoke from biomass burning. In Japan, there are also fine aerosols, but without the same absorption. This indicates urban pollution from Tokyo, blown toward the ocean and mixed with sea salt. The SPEXone polarization observations are displayed on a background true color image from another of PACE’s instruments, OCI.

With these data, scientists will be able to measure cloud properties — which are important for understanding climate — and monitor, analyze, and identify atmospheric aerosols to better inform the public about air quality. Scientists will also be able to learn how aerosols interact with clouds and influence cloud formation, which is essential to creating accurate climate models.
Early images from PACE’s HARP2 polarimeter captured data on clouds over the west coast of South America on Mar. 11, 2024. The polarimetry data can be used to determine information about the cloud droplets that make up the cloudbow – a rainbow produced by sunlight reflected by cloud droplets instead of rain droplets. Scientists can learn how the clouds respond to man-made pollution and other aerosols and can measure the size of the cloud droplets with this polarimetry data.
Credit: UMBC
“We’ve been dreaming of PACE-like imagery for over two decades. It’s surreal to finally see the real thing,” said Jeremy Werdell, PACE project scientist at NASA Goddard. “The data from all three instruments are of such high quality that we can start distributing it publicly two months from launch, and I’m proud of our team for making that happen. These data will not only positively impact our everyday lives by informing on air quality and the health of aquatic ecosystems, but also change how we view our home planet over time.”
The PACE mission is managed by NASA Goddard, which also built and tested the spacecraft and the ocean color instrument. The Hyper-Angular Rainbow Polarimeter #2 (HARP2) was designed and built by the University of Maryland, Baltimore County, and the Spectro-polarimeter for Planetary Exploration (SPEXone) was developed and built by a Dutch consortium led by Netherlands Institute for Space Research, Airbus Defence, and Space Netherlands.

Ice caps on Mars offer clues to ancient climates
As a first-year master's student in the Department of Earth Sciences, Katherine Lutz became fascinated by satellite images of Mars that showed spiraling shapes swirling across the planet's polar ice caps.
Consisting of alternating layers of ice and dusty deposits and measuring 400 to 1,000 meters deep, these spiral patterns aren't seen anywhere on Earth.
"These look amazing, but do we actually understand why they form or how they evolve over time?" asks Lutz, now a Guarini School of Graduate and Advanced Studies Ph.D. student and National Science Foundation Fellow in the lab of professor Marisa Palucis, whose research areas include planetary landscape evolution. "Why are they here? How can we use these features?"
The layers on the polar ice cap offer scientists one of the best climate records for the Red Planet.
"Mars has undergone massive climate change and we spend a lot of time as planetary scientists trying to understand that," Palucis says. "The question of how much water has flowed across its surface (and when) has been central to its exploration."
Research from 2013 had suggested these "troughs" might be caused by katabatic winds—winds that start off moving rapidly, causing erosion, and then quickly drop and slow down, resulting in deposits. As a result, the troughs would be expected to have asymmetric walls as well as cloud formations hovering over them that correspond with katabatic wind activity.
With Palucis and Earth sciences professor Robert Hawley, Lutz analyzed a decade's worth of new Mars images and data and discovered that while 80% of the troughs were indeed asymmetric, roughly 20% were not. Rather, the troughs on the outer edges of the ice cap form a fairly uniform "V" shape, with the walls on either side measuring about the same height. Further, not all troughs had cloud cover.
In a paper published in the Journal of Geophysical Research: Planets, the researchers posit that these outer troughs are younger than those in the center of the polar ice cap and are likely caused by heavy erosion versus a katabatic wind cycle.
That could suggest, Lutz says, that 4 to 5 million years ago, there was a shift in the Martian climate that altered the planet's water cycle, causing winds, clouds, and ice to flow differently.
This would help explain why the troughs in the center of the ice cap are different from the ones on the edges, Lutz says, they formed at different times, under different climate conditions.
This type of discovery is crucial in trying to decipher whether Mars can support—or has ever supported—life.
"If we ever want to have people on Mars, we need to figure out the history of this water source," says Lutz, referring to the ice layers in these spirals.
"Could we potentially be using it to, say, extract drinkable water? And if we ever want to find evidence of life there now, we're not going to look at the outer edges of the ice cap, where it's just a lot of erosion and no water going into the system and there's not a lot of heating."
Lutz is quick to point out that these ice-cap layers are only records of climate on modern Mars. More modeling is needed to further illuminate the history and function of these unique spiral features, with the eventual goal of sending a physical rover to Mars to "get some more concrete information" about the troughs.

NASA’s Compact Infrared Cameras Enable New Science - NASA
New Post has been published on https://sunalei.org/news/nasas-compact-infrared-cameras-enable-new-science-nasa/
NASA’s Compact Infrared Cameras Enable New Science - NASA
A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth’s upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition of other planets.
The cameras use sensitive, high-resolution strained-layer superlattice sensors, initially developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, using IRAD, Internal Research and Development funding.
Their compact construction, low mass, and adaptability enable engineers like Tilak Hewagama to adapt them to the needs of a variety of sciences.
“Attaching filters directly to the detector eliminates the substantial mass of traditional lens and filter systems,” Hewagama said. “This allows a low-mass instrument with a compact focal plane which can now be chilled for infrared detection using smaller, more efficient coolers. Smaller satellites and missions can benefit from their resolution and accuracy.”
Engineer Murzy Jhabvala led the initial sensor development at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, as well as leading today’s filter integration efforts.
Jhabvala also led the Compact Thermal Imager experiment on the International Space Station that demonstrated how the new sensor technology could survive in space while proving a major success for Earth science. More than 15 million images captured in two infrared bands earned inventors, Jhabvala, and NASA Goddard colleagues Don Jennings and Compton Tucker an agency Invention of the Year award for 2021.
Data from the test provided detailed information about wildfires, better understanding of the vertical structure of Earth’s clouds and atmosphere, and captured an updraft caused by wind lifting off Earth’s land features called a gravity wave.
The groundbreaking infrared sensors use layers of repeating molecular structures to interact with individual photons, or units of light. The sensors resolve more wavelengths of infrared at a higher resolution: 260 feet (80 meters) per pixel from orbit compared to 1,000 to 3,000 feet (375 to 1,000 meters) possible with current thermal cameras.
The success of these heat-measuring cameras has drawn investments from NASA’s Earth Science Technology Office (ESTO), Small Business Innovation and Research, and other programs to further customize their reach and applications.
Jhabvala and NASA’s Advanced Land Imaging Thermal IR Sensor (ALTIRS) team are developing a six-band version for this year’s LiDAR, Hyperspectral, & Thermal Imager (G-LiHT) airborne project. This first-of-its-kind camera will measure surface heat and enable pollution monitoring and fire observations at high frame rates, he said.
NASA Goddard Earth scientist Doug Morton leads an ESTO project developing a Compact Fire Imager for wildfire detection and prediction.
“We’re not going to see fewer fires, so we’re trying to understand how fires release energy over their life cycle,” Morton said. “This will help us better understand the new nature of fires in an increasingly flammable world.”
CFI will monitor both the hottest fires which release more greenhouse gases and cooler, smoldering coals and ashes which produce more carbon monoxide and airborne particles like smoke and ash.
“Those are key ingredients when it comes to safety and understanding the greenhouse gases released by burning,” Morton said.
After they test the fire imager on airborne campaigns, Morton’s team envisions outfitting a fleet of 10 small satellites to provide global information about fires with more images per day.
Combined with next generation computer models, he said, “this information can help the forest service and other firefighting agencies prevent fires, improve safety for firefighters on the front lines, and protect the life and property of those living in the path of fires.”
Probing Clouds on Earth and Beyond
Outfitted with polarization filters, the sensor could measure how ice particles in Earth’s upper atmosphere clouds scatter and polarize light, NASA Goddard Earth scientist Dong Wu said.
This applications would complement NASA’s PACE — Plankton, Aerosol, Cloud, ocean Ecosystem — mission, Wu said, which revealed its first light images earlier this month. Both measure the polarization of light wave’s orientation in relation to the direction of travel from different parts of the infrared spectrum.
“The PACE polarimeters monitor visible and shortwave-infrared light,” he explained. “The mission will focus on aerosol and ocean color sciences from daytime observations. At mid- and long-infrared wavelengths, the new Infrared polarimeter would capture cloud and surface properties from both day and night observations.”
In another effort, Hewagama is working Jhabvala and Jennings to incorporate linear variable filters which provide even greater detail within the infrared spectrum. The filters reveal atmospheric molecules’ rotation and vibration as well as Earth’s surface composition.
That technology could also benefit missions to rocky planets, comets, and asteroids, planetary scientist Carrie Anderson said. She said they could identify ice and volatile compounds emitted in enormous plumes from Saturn’s moon Enceladus.
“They are essentially geysers of ice,” she said, “which of course are cold, but emit light within the new infrared sensor’s detection limits. Looking at the plumes against the backdrop of the Sun would allow us to identify their composition and vertical distribution very clearly.”
