Macropost #1

             This semester, I’ve had the privilege to serve alongside Feast Down East, a non-profit organization based in Wilmington, NC. This small but fierce group of individuals is dedicated to the enhancement of local food systems through several unique program arms, including their food hub distribution center, farmer support program, mobile market, farm to fork CSA, and emerging farmer program. For more information on the important work regularly conducted by Feast Down East, you may visit their website.

             Team FEAST’s primary initiative this semester centered around the creation and distribution of a county-wide community needs assessment regarding food access gaps in Pender County, a rural county adjacent to urban New Hanover County. This project directly correlated with public health competency F7, “Assess population needs, assets, and capacities that affect communities’ health.” In order to achieve this goal, Team Feast first sought out insight from over 40 community partners (including local farmers, hospital agencies, food banks, and faith-based organizations) regarding the type of information they would like to glean from a community needs assessment. We received responses from 17 organizations concerning the types of questions and information which might prove beneficial to our goal, with question category suggestions ranging from transportation access, home garden utilization, knowledge of federal assistance programs, and perceptions of healthy food. Many agencies also advocated for the creation of a Spanish assessment due to the high rates of regional Spanish speakers. Several of these partners kindly agreed to aid us in the distribution of the assessment. In lieu of these responses, we constructed a 67-question survey in both English and Spanish which addressed the concerns of local organizations regarding food access. Thanks to the help of several Food Pantries and the local Cooperative Extension branch, we distributed the assessment to over 1,500 people in both electronic and print formats. Upon completion, we received approximately 100 partial and total survey responses, which are currently under analysis.

             To those unaffected by food insecurity, this assessment may appear as a mere formality. However, food insecurity plagues many individuals living in the United States, and is a topic especially pertinent to rural communities. According to the Map the Meal Gap 2020 Report, 87% of food insecure counties are rural, despite the fact that generous estimates designate only 63% of U.S. counties as rural (Feeding America, 2020). This means that rural communities are at a higher risk for food insecurity than urban communities, despite the common misconception of a bountiful, agrarian lifestyle linked with notions of rurality. More specifically, Feeding America (2020) reports a child food insecurity rate of 19.1% in Pender County with 67% of the county population meeting requirements for nutrition assistance programs. It is our hope that the results of our community needs assessment will shed light on any gaps which might exist in the local food environment, as well as any social determinants which are uniquely prohibitive in the process of local food acquisition.

           I would be remiss not to note the challenges which shroud both intervention and assessment efforts directed at alleviating food insecurity in rural areas. Through discussions with local community partners and a survey of previous literature, it became apparent that the social determinants of rural food insecurity are multifaceted and complex. Food insecurity is linked with poverty, minority-status, and lack of transportation and geographically tangible food stores (Ramadurai et al., 2012; Holston et al., 2020). Numerous participants in our survey noted significant travel distances to nearby stores and many noted their desire for increased access to fresh produce and meat. While federal programs can prove beneficial in the alleviation of this issue, it is not a definitive solution, and we must seek upstream interventions with the potential to strengthen the overarching economic environment of rural communities if we are to make any true headway (Dewitt et al., 2020). Furthermore, food insecurity is a touchy subject and something which many people are hesitant to disclose, especially if they are members of an already marginalized community, such as undocumented immigrants. Though we were explicit in our survey regarding assurance of anonymity, we were unable to acquire many responses from the Latinx population in Pender County. While this may be connected to our sampling method, it may also be partially attributable to immigration concerns.

             Overall, however, I am thrilled that I had the opportunity to conduct this assessment alongside a group of similarly motivated students, as well as a dedicated organizational team. This experience reiterated to me the importance of food insecurity intervention and assessment in the United States, especially within rural areas. Furthermore, observing the work of Feast Down East reminded me that it is possible to mitigate food insecurity and to increase access to nutritional, locally-sourced food for everyone, including those who are less affluent. It is my hope that Feast Down East will continue to expand their reach into Pender County and beyond, and perhaps our assessment will serve as an initial baseline study for continued evaluation and improvement.

Reflective Journal: Data Objects

 Experience Description:

The CT experience I decided to reflect on is our studio assignment of data objects (which I know is still an ongoing assignment kind of we're on our last day but this is the assignment that has stood out to me the most so far as its the assignment that I've had the most interest in and put in the most work for)

the project involved finding a data set and mapping it to an object by changing the object in some way to convey the data set we had. At the beginning of the assignment I had my heart set on doing something with music and as we were forming groups I quickly found myself in a group of people who were interested in the same subject

which made deciding what we wanted to do incredibly easy as we already had set ideas of what data we wanted to use and how we wanted to show it, using the techniques of brainstorming we learnt from ICT we very quickly decided on an object and the data set and moved on to organizing our data working on our final object.

Concepts/Prototyping:

One problem we faced or at least a problem that I've come to realize was actually a big problem in hindsight was not really doing many iterations or prototyping as we already had a final object and idea in mind we just went straight into formalizing what we wanted our final to be which was a record player and vinyl but as the project went on I soon realized the problems that came with not conceptualizing and prototyping especially when it came to wanting to add certain features into the record player it became an issue as we had no prototypes to test on so we had to test on the actual final product luckily, in my opinion, it worked out, but this moment of realization stood out to me because of what we learnt in classes about conceptualization and iteration and how important it is when working towards a final product we were incredibly fortunate enough to have most of our idea's end up working in the long run but we definitely ran into problems that could have been easily fixed by having multiple concepts and prototypes.  

Investigation:

In the book Design Approaches and Tools in Education and training by Nienke Nieveen he states how in order to reach product quality, prototyping is seen as the best method to getting to a high degree of quality using extensive prototypes, iteration and formative evaluation. Nieveen also states how important user involvement is he illustrates how prototyping helps to enhance the transparency of the entire conceptual process. 

Conclude with different ways of doing things, the most important thing I took out of this book was that prototyping is the preliminary version of a product before full commitment to develop it and how a prototype will continually be refined to eventually form a final product I’ve come to the conclusion that his is incredibly important as jumping to working on the final product as stated above indefinitely causes problems also from reading the book I realized that there could possibly still be issues with the final product as we haven’t gone through the prototyping cycle to see what does and does not work, what would have helped would have been using throw-away prototypes, According to Nieveen “throw-away prototypes clarify possible consequences of specific design ideas” this would obviously help weed out most if not all problems without final design.

Another problem our group faced was Time Management and Communication as the days went on especially during the study break I realized that my group had gone radio silent and weren’t generating more ideas I was unsure whether or not they were working on our project or not during our break, I decided it would be best to trust our team and continue on with what I was appointed to do, a lot of what I did I won't lie was definitely last minute and possibly a little rushed and the result of which caused some of the work I produced to be sloppy and i would consider unfinished although finished enough to be acceptable Time Management was definitely one of my biggest downfalls and after researching and stumbling upon the book “The Time Trap” by Alec Mackenzie and Pat Nickerson I’ve learnt how important it is to have open communication in group work and how to manage my time efficiently, not to fall into “Time Traps” and how to set and stick with priorities one quote from the book about communication was “Despite its challenges, we take for granted that communication is simply a natural activity, a skill or gift we are born with. It starts with our first wails in the delivery room—with parents and infant taking turns! Through a lifetime of encounters, we ascend to more and more convoluted conflicts in conference rooms, classrooms, or courtrooms—communicating every waking hour.” this quote alone helped me realize that communication is something we’re born to be able to do so why did we find it so difficult to have communication with each other throughout the project, this leads me to my next subject; time management Mackenzie and Nickerson touch on Escaping distracting and focusing on goals, escaping expectations and pull into reality instead these are all incredibly valuable life lessons I will try my very best to put into my work.

Conclusion:

in conclusion reflecting back on this project has made me realize how crucial Prototyping can be especially to unveil potential consequences with your project It’s also helped me notice how bad I am with time management and communicating with groups I hope to rectify these issues with myself in future projects and strive to be an important asset for the groups I work within the next projects I take on and continue to be that way for when I leave university looking back on our project I feel some regret for not being able to use the knowledge I have now on the project but I also feel grateful as without this experience I would have never learnt what I could have done better.

Tattooing as Punishment

In Roman times, tattooing was seen as a mark of distinction for those who committed acts of misconduct against the state. Prisoners were often tattooed as a “state control mechanism” (Fisher, 2). Now, people could glance at their tattooed identities and be able to place the prisoner or slave’s role in society.

There were three main types of penal tattoos, identified by Gustafson (2000):

1. The name of the criminal

2. The name of the emperor under which the crime was committed

3. The name of the punishment the criminal was given

Centuries later, in the 1800s, French and Italian criminologists became interested in studying tattoos on criminals. The major different between tattooing and criminals from Roman times and the 1800s was that criminals were now tattooing themselves voluntarily, perhaps as a method of committing to their crimes, or even showing them off.

Pulp: Cover Art by Distinguished Artists

Last semester, Professor Jessica FitzPatrick’s class, Narrative & Technology, visited Archives & Special Collections to work with an array of materials including science fiction pulp magazines, science fiction fanzines, comic books, and artists’ books (just to name a few). For extra credit, students had the opportunity to submit a blog post to be featured on our Tumblr. What a perfect fit for #scififriday!

Figure 1: The artwork of Virgil Finlay for Fate Magazine

We often emphasize the importance of first impressions. The very first time that we meet someone or see something makes all the difference. I experienced this phenomenon when encountering science fiction pulp magazines for the first time. My eyes were first drawn in by the vibrant colors on the front page and then my gaze lingered as I glanced over the provocative headlines and the female on the front cover. This visual experience made me eager to learn more about these cover artists and their contributions to the production of pulp magazines.                                                

After doing some research, I found that many cover artists became as popular as the authors of the pieces within. While the editors of these magazines made decisions about the glossy paper to print the covers on, the artists used these choices to their advantage. They utilized sleek, higher quality paper for their artwork that contrasted with the cheap and rugged pulp paper inside. Interestingly, these covers would sometimes be designed before any content of the magazine was written (“Pulp Magazine”). In other words, artists would look to the cover art for inspiration. For this project, I focused specifically on the artwork of Virgil Finlay for Fate Magazine and the artwork of Richard Van Dongen for Astounding Science Fiction. I will be commenting on visual techniques and themes used on these covers that served the purpose of gaining the readership of their intended audiences as well as fueling the content written within.                                       

The first pulp cover that I examined was by a well-known cover artist at the time, Virgil Finlay. An obvious feature of this cover is the portrayal of the typical damsel in distress female. To go along with this are the words, “sex and hypnotism”, which indicate the provocative and exploitative nature of this pulp. This sexualized depiction of women was a common feature of sci-fi pulps that were targeted toward a largely male audience. Finlay’s style for this particular art piece is one of very bright, contrasting colors. This differs from much of his work in which he used black ink with a scratchboard technique. For these black and white illustrations, Finlay used a sharp blade to scratch away white lines from a clay board covered in black ink (Parker). While black and white ink creates an obvious contrast, Finlay chose to use the colors red and green to create a similar effect in this cover art. He cleverly chose to color the woman’s dress green to make her stand out against the swirling red background. Another indicator of her importance to the interest of perspective pulp readers is that we get to see her full face, while we only get to see the side profile of the hypnotist.

Figure 2: Psychiatry Looks at Hypnosis by John C. Ross

As you can see from Figure 2, the cover serves as a good indication of what is published within. In the piece, “Psychiatry looks at Hypnosis,” there is an illustration depicting a male psychiatrist conducting an evaluation on a troubled female figure. While she is not portrayed as provocatively as the female on the front cover, she is positioned in the foreground of the image. The focus remains on the female, while the psychiatrist remains in the background. While I am uncertain if Finlay’s cover art for this pulp was produced before the written content, that is my speculation based on this connection between the female figures in each.

Figure 3: The artwork of Van Dongen for Astounding Science Fiction 

The other pulp artist that I came across offered a contrasting style with the art of Finlay. Van Dongen used a different method than the female physique to appeal to the largely male readership. He relied instead on a realistic style that matched the pulp editor, John W Campbell’s  vision of a “more dignified” looking science fiction pulp (Gustafson, Nicholls, Westfahl, & Langford). Rather than illustrating a female in bright colors, he relied on the oddity of an alien creature sharing some brews with the captain of a ship (Figure 3). His colors are more dull and there is not one thing that sticks out more than others. This cover did not catch my eye in the same way, but it still serves a purpose. It is far less provocative than the cover of Fate Magazine which may suggest that the authors of Astounding Science Fiction (and its artists) made the effort appeal to those who are more interested in genre of Science Fiction itself.

Figure 4: An article found withing Astounding Science Fiction

As the front page had led me to guess, one of the pieces inside of this pulp seemed to be targeted toward those interested in the subject of science itself. On one of the first pages of this pulp, there was an article about an electric kit for “brainiacs” (Figure 4). There is an illustration of a male to go along with this, of course.

Virgil Finlay and Van Dongen were two distinguished pulp artists with very different styles. Finlay began his career in 1935 where he began doing interior magazine illustrations. In addition to this, he also illustrated the cover art of upwards of 60 magazine covers. He is well-known for both his mentioned black-and-white style as well as the color illustrations such as the one for Fate Magazine. He was nominated for seven Hugo Awards (science fiction literary awards) and inducted into the Science Fiction Hall of Fame in 2012. (Gustafson, Nicholls, & Westfahl). Van Dongen on the other hand, entered the science fiction field in 1950 after going to school and training in retouching photographs. During his career, he painted over 40 covers for Astounding Science Fiction as well as Worlds Beyond, Space Science Fiction, and Science Fiction Adventures. Van Dongen received the Hugo Best Artist award in 1959 for his work in Astounding Science Fiction (Gustafson, Nicholls, Westfahl, & Langford). Finlay and Van Dongen each made a name for themselves in the field of science fiction pulp. The similarity that they share is the ability of their artwork to draw in readers and to fuel the content of what lies on the pages within.

Fund in der Antarktis Riesiges Wasserreservoir verbirgt sich unter Gletscher 06.05.2022, 11:44 Uhr Lange spekulieren Wissenschaftler, dass riesige Grundwasserspeicher unter dem antarktischen Eis verborgen liegen könnten. Nun findet ein Expeditionsteam einen solchen Aquifer. In der Nähe des Ross-Eisschelfs in der Antarktis haben Forschende ein riesiges Wasserreservoir im Untergrund eines Gletschers nachgewiesen. Das flüssige Wasser steht in einem Sedimentbecken, das bis zu 1,3 Kilometer tief ist. Würde man das Sediment entfernen, ergäbe sich eine Wassersäule mit einer Höhe zwischen 220 und 820 Metern. Das Entdeckerteam geht davon aus, dass das Wasser die Geschwindigkeit des darüber liegenden Whillans-Eisstroms beeinflusst und dass es noch mehr tiefe Wasserreservoire in der Antarktis gibt. Die Studie der Forschergruppe um Chloe Gustafson von der Columbia University in Palisades (New York, USA) ist in der Fachzeitschrift "Science" erschienen. Das Feldlager des vierköpfigen Teams am Whillans Ice Stream. (Foto: Kerry Key, Lamont-Doherty Earth Observatory, Columbia University) "Andere haben die Hypothese aufgestellt, dass sich in diesen Sedimenten tiefes Grundwasser befinden könnte, aber bis jetzt hat noch niemand detaillierte Aufnahmen gemacht", erklärte Gustafson. Sie und ihr Team verwendeten Seismometer und die sogenannte passiv-seismische Methode, um aus der Analyse leichter Erdbebenwellen Schlüsse über den Aufbau des Untergrunds zu ziehen. Zudem nutzten sie eine Technologie, die in der Antarktis bisher nur angewendet wurde, um Strukturen in zehn oder mehr Kilometern Tiefe aufzuklären: die Magnetotellurik. Dabei werten die Wissenschaftler Daten zur elektrischen Leitfähigkeit von Strukturen im Untergrund aus. Natürliche Magnetfelder lösen im Erdinneren elektrische Wirbelströme aus, die wiederum Magnetfelder erzeugen, die dann aufgezeichnet und analysiert werden können. Mithilfe dieser Technologie konnten Gustafson und Kollegen die Tiefe und Ausdehnung des Sedimentbeckens bestimmen. Da Salzwasser elektrischen Strom besser leitet als Süßwasser, konnten sie auch den Salzgehalt des Wassers bestimmen: Er ist im oberen Bereich des Sediments niedriger als bei Meerwasser, nimmt mit der Tiefe jedoch zu. Hinweis auf riesiges Meeresbecken Dieses Ergebnis interpretieren die Forscher so: Vor tausenden Jahren war das Sedimentbecken ein Meeresboden, deshalb ist das Sediment mit Salzwasser gefüllt. Der nach oben abnehmende Salzgehalt ist für die Forscher ein Indiz dafür, dass das Wasserreservoir mit dem Schmelzwasser am Gletscherboden in Verbindung steht, dass also Schmelzwasser eingesickert ist. Das Wasser am Gletscherboden verringert die Reibung, wenn sich der Gletscher über Fels oder Sediment bewegt. Das Wasser beeinflusst also die Fließgeschwindigkeit des Gletschers und die Menge des Eises, die ins Meer gelangt - und die dann zum Anstieg des Meeresspiegels im Zuge des Klimawandels beiträgt. Um den Einfluss des Grundwassers auf das Verhalten von Gletschern besser zu verstehen, sollten solche Wasserreservoire in die nächste Generation von Eisschildmodellen integriert werden, empfehlen die Wissenschaftlerinnen und Wissenschaftler. Außerdem raten sie zur Anwendung der auf Elektromagnetik beruhenden Messmethode Magnetotellurik: "Ich hoffe, dass die Menschen Elektromagnetik als Teil des standardmäßigen geophysikalischen Instrumentariums der Antarktis betrachten werden", so Gustafson, die auch an der University of California San Diego in La Jolla (Kalifornien, USA) tätig ist. In einem "Science"-Kommentar weist Winnie Chu vom Georgia Institute of Technology in Atlanta (Georgia, USA) darauf hin, dass das Grundwasser auch dazu beitragen könnte, dass der Gletscher langsamer fließt: "Wenn das Grundwasser-Reservoir eine beträchtliche Menge an subglazialem Wasser aufnehmen kann, würde die Menge an Schmierwasser, die zum Gleiten auf festem Untergrund beiträgt, reduziert." Wie das Grundwasser tatsächlich auf das Gletscherverhalten wirkt, müsse nun noch erforscht werden.

SCRAM Authentication in RDS for PostgreSQL 13

The Salted Challenge Response Authentication Mechanism (SCRAM) greatly improves the security of password-based user authentication by adding several key security features that prevent rainbow-table attacks, man-in-the-middle attacks, and stored password attacks, while also adding support for multiple hashing algorithms and passwords that contain non-ASCII characters. PostgreSQL 10 added support for SCRAM authentication, and AWS customers have been able to use SCRAM authentication since Amazon RDS for PostgreSQL 10 was launched. However, the use of SCRAM authentication was optional and could not be required for all users at a server level. With the launch of Amazon RDS for PostgreSQL 13, you now control whether or not SCRAM authentication is required for all database users. In this post we explain how to require SCRAM authentication on your RDS for PostgreSQL database instances. We use the AWS Command Line Interface (AWS CLI), which allows you to interact with the AWS control plane from a Linux, UNIX, or Macintosh shell, or the AWS CloudShell. You can also implement this solution on the AWS Management Console, if you prefer. Upgrading your client libraries All users and applications that access the database need to use client libraries that support SCRAM. The PostgreSQL Wiki has a list of client library versions and which ones support SCRAM. Applications and users who use client libraries that don’t support SCRAM can’t connect to the database once you require SCRAM authentication. Creating a database parameter group Database parameter groups are collections of database server settings that control how your RDS instance behaves. Each parameter group has a number of database settings, some of which are changeable and some of which are not. Database parameter groups allow you to have a single standard configuration for all your databases so that they behave in a uniform way. By default, RDS instances use a default parameter group, whose settings can’t be modified. Therefore, you can’t use the default parameter group for this procedure. Although sharing parameter groups across multiple database instances is helpful, there is also one drawback: any change made to the parameter group is applied to all database instances that use that parameter group. If you modify your shared parameter group to require SCRAM authentication, then SCRAM authentication is required on all database instances that use that parameter group. Therefore, you must create a separate parameter group for use during this procedure. PostgreSQL 10 introduced a parameter called password_encryption, which tells the PostgreSQL database which password encryption mechanism to use by default. The default is md5, but you can also choose scram-sha-256 to tell PostgreSQL that you want to use the newer SCRAM password hashing algorithm by default. To create a database parameter group and configure it to default to SCRAM password encryption, use the following commands: aws rds create-db-parameter-group --db-parameter-group-name 'scram-passwords' --db-parameter-group-family postgres13 --description 'Implements SCRAM passwords' aws rds modify-db-parameter-group --db-parameter-group-name 'scram-passwords' --parameters 'ParameterName=password_encryption,ParameterValue=scram-sha-256,ApplyMethod=immediate' Configuring the server password encryption setting Let’s assume that your database instance identifier is PG13DB. To attach the new parameter group to your database instance, use the following command: aws rds modify-db-instance --db-instance-identifier 'PG13DB' --db-parameter-group-name 'scram-passwords' aws rds wait db-instance-available --db-instance-identifier 'PG13DB' Changing to the new parameter group doesn’t re-encrypt any existing passwords, nor does it require that users authenticate using SCRAM. Instead, it instructs the server to use the SCRAM method when users change their passwords from this point on. You can run a server with a mix of MD5 and SCRAM passwords, and changing this parameter doesn’t affect any users who currently have MD5 passwords. Switching a database instance to a different parameter group requires a reboot. If you’re working with a production database, I recommend waiting until the next database maintenance window for the instance to be rebooted and for these changes to be applied. If you’re working with a development or test database, you can reboot the instance immediately using the following command: aws rds reboot-db-instance --db-instance-identifier 'PG13DB' Checking for users with non-SCRAM passwords Before you begin enforcing SCRAM authentication, you should determine which users (if any) currently have MD5 passwords by running the following commands in a PostgreSQL session: => CREATE EXTENSION rds_tools; => select * from rds_tools.role_password_encryption_type(); Role Name | Encryption Method ————————————————— mydbuser1 | md5 mydbuser2 | mydbuser3 | scram mydbuser4 | Users that show md5 in the Encryption Method column can’t authenticate after you modify the following parameter. Therefore, it’s important to update the password for each user that has an MD5 password before proceeding to the next step. You can change an individual user’s password using the following SQL command while connected to the server using the psql tool: password mydbuser1 This method is preferred to using ALTER ROLE, because ALTER ROLE statements might get logged or transmitted in plaintext, potentially exposing the user’s new plaintext password to anyone with access to those logs or network paths. According to the PostgreSQL documentation: Caution must be exercised when specifying an unencrypted password with this command. The password will be transmitted to the server in cleartext, and it might also be logged in the client’s command history or the server log. psql contains a command password that can be used to change a role’s password without exposing the cleartext password. Modifying the database parameter group to require SCRAM After all your users and applications are upgraded to use client libraries that support SCRAM, and all your passwords are updated to the SCRAM format, you can configure RDS for PostgreSQL to require SCRAM authentication on your database. The rds.accepted_password_auth_method parameter tells Amazon RDS for PostgreSQL to allow both MD5 and SCRAM passwords, or to only allow SCRAM passwords. The default setting of md5+scram lets users with either MD5 or SCRAM passwords authenticate. Setting this parameter to scram forces the PostgreSQL server to only permit SCRAM passwords. You can make this change by updating the parameter group using this command: aws rds modify-db-parameter-group --db-parameter-group-name 'scram-passwords' --parameters 'ParameterName=rds.accepted_password_auth_method,ParameterValue=scram,ApplyMethod=immediate' Because you’re modifying a dynamic parameter on a parameter group that’s already attached to the database instance, rather than attaching a different parameter group to the database instance, you don’t have to reboot for this change to take effect. After you update this parameter, new connections to the Amazon RDS for PostgreSQL server are required to use SCRAM authentication. New connections that attempt to use MD5-based authentication fail, even if the database user still has an MD5 password. Connections that are currently in flight aren’t affected by this change. Summary In this post, you learned how to improve the security posture of your Amazon RDS for PostgreSQL 13 server by requiring that all database users use SCRAM-based password hashing and authentication. When you implement this change on your RDS for PostgreSQL 13 servers, we would love to hear about how the transition went in the comments section.

Mats Gustafson illustration research page.

Mats Gustafson is a Swedish fashion illustrator who began his illustration career in the late 1970s. His work has been featured in numerous publications such as, Vogue and Vogue Italia, the New Yorker and Harper’s bazaar. He works in both watercolour and pastels to create a wonderful peice of artwork.

When searching for fashion illustrators, Mats Gustafson’s work immediately stood out to me as his work looks careless but creates such emphasis when presented on a page. The use of the bright coloured pastels for the garments makes the piece vibrant and exciting. I recreated three of Gustafsons work in three different formats that I have previously used in my fashion illustration blog which are the Half and Half method, Enlargement and Direct copy. I have presented this at the top of this page along with a video of the process of the page layout and background ideas.

Fund in der Antarktis Riesiges Wasserreservoir verbirgt sich unter Gletscher 06.05.2022, 11:44 Uhr Lange spekulieren Wissenschaftler, dass riesige Grundwasserspeicher unter dem antarktischen Eis verborgen liegen könnten. Nun findet ein Expeditionsteam einen solchen Aquifer. In der Nähe des Ross-Eisschelfs in der Antarktis haben Forschende ein riesiges Wasserreservoir im Untergrund eines Gletschers nachgewiesen. Das flüssige Wasser steht in einem Sedimentbecken, das bis zu 1,3 Kilometer tief ist. Würde man das Sediment entfernen, ergäbe sich eine Wassersäule mit einer Höhe zwischen 220 und 820 Metern. Das Entdeckerteam geht davon aus, dass das Wasser die Geschwindigkeit des darüber liegenden Whillans-Eisstroms beeinflusst und dass es noch mehr tiefe Wasserreservoire in der Antarktis gibt. Die Studie der Forschergruppe um Chloe Gustafson von der Columbia University in Palisades (New York, USA) ist in der Fachzeitschrift "Science" erschienen.

(Foto: Kerry Key, Lamont-Doherty Earth Observatory, Columbia University) "Andere haben die Hypothese aufgestellt, dass sich in diesen Sedimenten tiefes Grundwasser befinden könnte, aber bis jetzt hat noch niemand detaillierte Aufnahmen gemacht", erklärte Gustafson. Sie und ihr Team verwendeten Seismometer und die sogenannte passiv-seismische Methode, um aus der Analyse leichter Erdbebenwellen Schlüsse über den Aufbau des Untergrunds zu ziehen. Zudem nutzten sie eine Technologie, die in der Antarktis bisher nur angewendet wurde, um Strukturen in zehn oder mehr Kilometern Tiefe aufzuklären: die Magnetotellurik. Dabei werten die Wissenschaftler Daten zur elektrischen Leitfähigkeit von Strukturen im Untergrund aus. Natürliche Magnetfelder lösen im Erdinneren elektrische Wirbelströme aus, die wiederum Magnetfelder erzeugen, die dann aufgezeichnet und analysiert werden können. Mithilfe dieser Technologie konnten Gustafson und Kollegen die Tiefe und Ausdehnung des Sedimentbeckens bestimmen. Da Salzwasser elektrischen Strom besser leitet als Süßwasser, konnten sie auch den Salzgehalt des Wassers bestimmen: Er ist im oberen Bereich des Sediments niedriger als bei Meerwasser, nimmt mit der Tiefe jedoch zu. Hinweis auf riesiges Meeresbecken Dieses Ergebnis interpretieren die Forscher so: Vor tausenden Jahren war das Sedimentbecken ein Meeresboden, deshalb ist das Sediment mit Salzwasser gefüllt. Der nach oben abnehmende Salzgehalt ist für die Forscher ein Indiz dafür, dass das Wasserreservoir mit dem Schmelzwasser am Gletscherboden in Verbindung steht, dass also Schmelzwasser eingesickert ist. Das Wasser am Gletscherboden verringert die Reibung, wenn sich der Gletscher über Fels oder Sediment bewegt. Das Wasser beeinflusst also die Fließgeschwindigkeit des Gletschers und die Menge des Eises, die ins Meer gelangt - und die dann zum Anstieg des Meeresspiegels im Zuge des Klimawandels beiträgt. Um den Einfluss des Grundwassers auf das Verhalten von Gletschern besser zu verstehen, sollten solche Wasserreservoire in die nächste Generation von Eisschildmodellen integriert werden, empfehlen die Wissenschaftlerinnen und Wissenschaftler. Außerdem raten sie zur Anwendung der auf Elektromagnetik beruhenden Messmethode Magnetotellurik: "Ich hoffe, dass die Menschen Elektromagnetik als Teil des standardmäßigen geophysikalischen Instrumentariums der Antarktis betrachten werden", so Gustafson, die auch an der University of California San Diego in La Jolla (Kalifornien, USA) tätig ist. In einem "Science"-Kommentar weist Winnie Chu vom Georgia Institute of Technology in Atlanta (Georgia, USA) darauf hin, dass das Grundwasser auch dazu beitragen könnte, dass der Gletscher langsamer fließt: "Wenn das Grundwasser-Reservoir eine beträchtliche Menge an subglazialem Wasser aufnehmen kann, würde die Menge an Schmierwasser, die zum Gleiten auf festem Untergrund beiträgt, reduziert." Wie das Grundwasser tatsächlich auf das Gletscherverhalten wirkt, müsse nun noch erforscht werden.
