Sharpening Our View of Climate Change with the Plankton, Aerosol, Cloud, ocean Ecosystem Satellite

As our planet warms, Earth’s ocean and atmosphere are changing.

Climate change has a lot of impact on the ocean, from sea level rise to marine heat waves to a loss of biodiversity. Meanwhile, greenhouse gases like carbon dioxide continue to warm our atmosphere.

NASA’s upcoming satellite, PACE, is soon to be on the case!

Set to launch on Feb. 6, 2024, the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission will help us better understand the complex systems driving the global changes that come with a warming climate.

Earth’s ocean is becoming greener due to climate change. PACE will see the ocean in more hues than ever before.

While a single phytoplankton typically can’t be seen with the naked eye, communities of trillions of phytoplankton, called blooms, can be seen from space. Blooms often take on a greenish tinge due to the pigments that phytoplankton (similar to plants on land) use to make energy through photosynthesis.

In a 2023 study, scientists found that portions of the ocean had turned greener because there were more chlorophyll-carrying phytoplankton. PACE has a hyperspectral sensor, the Ocean Color Instrument (OCI), that will be able to discern subtle shifts in hue. This will allow scientists to monitor changes in phytoplankton communities and ocean health overall due to climate change.

Phytoplankton play a key role in helping the ocean absorb carbon from the atmosphere. PACE will identify different phytoplankton species from space.

With PACE, scientists will be able to tell what phytoplankton communities are present – from space! Before, this could only be done by analyzing a sample of seawater.

Telling “who’s who” in a phytoplankton bloom is key because different phytoplankton play vastly different roles in aquatic ecosystems. They can fuel the food chain and draw down carbon dioxide from the atmosphere to photosynthesize. Some phytoplankton populations capture carbon as they die and sink to the deep ocean; others release the gas back into the atmosphere as they decay near the surface.

Studying these teeny tiny critters from space will help scientists learn how and where phytoplankton are affected by climate change, and how changes in these communities may affect other creatures and ocean ecosystems.

Climate models are one of our most powerful tools to understand how Earth is changing. PACE data will improve the data these models rely on.

The PACE mission will offer important insights on airborne particles of sea salt, smoke, human-made pollutants, and dust – collectively called aerosols – by observing how they interact with light.

With two instruments called polarimeters, SPEXone and HARP2, PACE will allow scientists to measure the size, composition, and abundance of these microscopic particles in our atmosphere. This information is crucial to figuring out how climate and air quality are changing.

PACE data will help scientists answer key climate questions, like how aerosols affect cloud formation or how ice clouds and liquid clouds differ.

It will also enable scientists to examine one of the trickiest components of climate change to model: how clouds and aerosols interact. Once PACE is operational, scientists can replace the estimates currently used to fill data gaps in climate models with measurements from the new satellite.

With a view of the whole planet every two days, PACE will track both microscopic organisms in the ocean and microscopic particles in the atmosphere. PACE’s unique view will help us learn more about the ways climate change is impacting our planet’s ocean and atmosphere.

Quanta meraviglia sopra di noi.

Hi.

At the moment, I'm on a bit of a block because I'm lacking words to use instead of 'pace'. As in, I'm writing a smut and I don't know what to use besides that word. I'm not asking for vocabulary that one should use exclusively to explicit material, but if you can provide one that one can utilize in correlation to one's hips or hand movement, that'd be amazing.

Hi! Here are some alternatives to pace (i.e, rate of movement).

Cadence - the beat, time, or measure of rhythmical motion

Caress - a light stroking, rubbing, or patting

Celerity - rapidity of motion or action

Convulse - to shake with or as if with irregular spasms

Glide - to move smoothly, continuously, and effortlessly

Lilt - a rhythmical swing, flow, or cadence; a springy buoyant movement

Momentum - strength or force gained by motion

Pound - pulsate, throb; move heavily and repeatedly

Pulsate - to throb or move rhythmically; vibrate

Rhythm - movement, fluctuation, or variation marked by the regular recurrence or natural flow of related elements

Ripple - to move with an undulating (i.e., wavelike) motion

Stroke - a single unbroken movement; especially: one of a series of repeated or to-and-fro movements

Surge - to move with a surge or in surges (i.e., series of swells or billows)

Sway - to swing slowly and rhythmically back and forth from a base or pivot

Swing - a sweeping or rhythmic movement of the body or a bodily part

Tempo - rate of motion or activity; pace

Throb - to beat or vibrate rhythmically

Tremble - a fit or spell of involuntary shaking or quivering

Undulate - to form or move in waves; to cause to move in a wavy, sinuous, or flowing manner

Wave - to move to and fro

Hope this helps with your writing. Do tag me, or send me a link. I'd love to read your work!

NON ERAVAMO NECESSARI

Già vent'anni fa in piazza gridavamo: “Anche in Jugoslavia morivano i bambini / non c’era Berlusconi ma c’erano i diessini”, e si manifestava davanti all’aeroporto militare di Pisignano, contro gli aerei di D'Alema che andavano a bombardare quelle terre. Per questo le posizioni di una certa sinistra non mi soprendono. Per queste persone un ucraino sarà sempre un eroe e un palestinese sempre un terrorista. Il partigiano Giammarchi a 90 anni suonati ci diceva di stare attenti ai guerrafondai, perché ci sono e ci saranno sempre, a destra e a sinistra. E ricordava che sebbene la Resistenza avesse vinto, lui aveva perso, perché metà della sua famiglia era morta sotto i bombardamenti. La guerra la vogliono i governi, la gente ne esce sempre sconfitta. Ma è un concetto troppo di sinistra per Serra, Scurati e Vecchioni. Continuino pure a esaltare questa presunta superiorità europea, io preferisco ricordare le parole del poeta russo Boris Slutskij, che al fronte c’era stato veramente: “Quando siamo tornati dalla guerra / ho capito che non eravamo necessari.” Questo, a mio parere, è il nucleo di tutta la faccenda.

Some seem to be desynchronized in their relationships. They feel oppressed, because they cannot move forward together and at the same pace. Their thinking is often incongruent, their motivation disparate. The phone could be a mediator, as it creates an impression to be a perfect reliable friend. However, in the end, it causes rather a sense of isolation, since it divides more than it unites. Eventually it appears not to be such a good friend but only a ghost friend.
