Did you know that some of the smallest organisms 🦠 in polar regions play an outsized role in their ecosystems?

Enter ✨diatoms✨ —microscopic algae with complex glass-like “shells” (frustules) made of silica. They can thrive in icy waters, forming a vital base of the food web.

Polar diatoms may be tiny, but they’re like nature’s holiday decorators 🎄! Their silica frustules are intricately patterned with delicate, ornamental designs, showcasing a remarkable diversity of ~200,000 unique species. Whether floating beneath sea ice or in pristine polar lakes, diatoms bring life to the coldest corners of the planet 🧊.

Diatoms provide energy⚡️for everything from zooplankton to whales 🐋! But diatoms don’t just feed the ocean and freshwaters – they help regulate the Earth’s climate. Through photosynthesis, diatoms absorb carbon dioxide and release oxygen, contributing an estimated 20-30% of the oxygen we breathe!

💡Fun fact: some scientists study diatoms preserved in sediment cores to learn about past climate – like unwrapping Earth’s history 🎁! Take a look at the images in this post to explore the contrast between living diatoms and preserved diatom remains.

❄️Snowflakes have long symbolized Christmas🎄 cheer. In Victorian times, crafting paper snowflakes became a festive tradition, inspired by their intricate and unique natural designs. But is it true that every snowflake is unique?🤔

At cold temperatures🥶, ice crystals can form in the atmosphere from water vapor💨💦. The ice crystal shape strongly depends on the temperature🌡️ and the supersaturation conditions. At around -15°C, ice crystals occur as so-called dendrites. Dendrites are six-branched ice crystals that look like what we commonly think of when picturing a snowflake. However, ice crystals can come in a large variety of different shapes. At around -5°C and high supersaturation, ice crystals look like tiny needles. Snowflakes often consist of multiple – sometimes up to hundreds of – individual ice crystals🌨️. That’s because ice crystals can stick to each other, when they come in contact, forming an “aggregate” snowflake.

Because the snowflake shape is so sensitive to the processes that were active during its formation and growth, every snowflake is truly unique. Next time it’s snowing, try to catch a snowflake on your jacket🧥 or glove 🧤(works best on black wool) and have a good look at it. Maybe you can identify some parts of its history.🤗

Herzliche Einladung zur POLARSTUNDE im Dezember ❄️

Die Deutsche Gesellschaft für Polarforschung (DGP) @polargesellschaft, die Association of Polar Early Career Scientists (APECS) Germany und der Schwerpunktprogramm Antarktisforschung der Deutschen Forschungsgemeinschaft @sppantarktisforschung laden euch erneut ein die “Forschung der Extreme” deutscher Polarforschung in Form von zwei kurzen und lebendigen Vorträgen kennenzulernen (Vorträge auf deutsch).

Am Mittwoch, den 04.12.2024, geben Dr. Celia Baumhoer (DLR) und Erik Leobel (AWI) einen Einblick in aktuelle deutsche Spitzenforschung. Von 17 bis 18 Uhr präsentieren sie “KI in der Polarforschung: Wie Deep Learning hilft, die Kryosphäre zu verstehen”. Wir laden alle herzlich ein, an der Seminarreihe teilzunehmen und mit zu diskutieren.

Bitte meldet euch per Email an polarstunde@polarforschung.de bis spätestens zum Vortag der jeweiligen Veranstaltung an. An alle Teilnehmenden wird der entsprechende (kostenlose) Zoom-Link rechtzeitig am Tag der Veranstaltung verschickt.

Let's celebrate Antarctica Day (1st December 2024

Let's celebrate Antarctica Day (1st December 2024 at 5pm CEST/ 4pm UTC) together and virtually travel to a deep-field camp in Antarctica to talk about fieldwork and life there. ❄️
After a planned interview you will have the chance to ask your own questions about the remote life in Antarctica or the research in limnology, chemistry and microbiology.

Sign up to the event in this google form and we will share the zoom link 24 h ahead of the call: https://forms.gle/XE6AXD2yHNEEAwQ19

Hope to see you there! 🤗

Last week, the "Deutsches Jungforscher Netzwerk - juFORUM e.V." (@juforum) was in Bremerhaven to get young people enthused about polar 🐻‍❄️🐧and marine🌊 research. In addition to many exciting research presentations and a tour of the research vessel Polarstern🚢, our board member Erik Loebel was there to present about APECS Germany ❄️ and our latest activities.🤗

❄️Come join us for our next Let's Talk session

❄️Come join us for our next Let's Talk session on polar advocacy on November 27th at 5pm Berlin time!

As polar scientists, it is not unusual to feel a bit hopeless - we are confronted with the reality of climate change 🌡️, biodiversity loss, and changes in sea ice extent every day🧊. We at APECS Germany are trying to help and have invited a panel of polar scientists who have made it their mission to amplify the voice of the poles. 🐻‍❄️🐧Come join us and find out about different paths available to channel our concerns into tangible change. Whether you are interested in outreach work, political activism, or ways to make advocacy a part of your career - our panelists bring with them a wide array of experiences. We will also aim to touch on tough topics, such as balancing political activism with scientific objectivity. 💪🏼🤗

Our panelists made it their mission to amplify the voice of the Arctic and Antarctica:

-Dr Jilda Caccavo (a researcher, active in and leading several SCAR groups, including SCAR and SCAR Ant-ICON, which focuses on bringing science and policy together for conservation goals in Antarctica) -Franziska Pausch (a representative from @awis4future, a group of Alfred Wegener Institute Researchers involved in @scientists4future)
-Hugo Guímaro @hguimaro(an ECR who is highly involved in education and outreach activities related to polar science, raising awareness for environmental issues, @apecs.polar, @apecs.portugal)
- Franziska Hasenburg (researcher and climate change activist in the "Arctic Climate Action Group" in Svalbard, @franziskahasenburg, @arcticclimateaction)

The event will be held in English and will be hosted online. In order to provide a welcoming environment where everybody feels comfortable asking tough questions, we generally do not share recordings from our Let’s Talk Series. We may, on occasion, share small videos snippets of answers from our individual panelists (with their permission). Bring your questions and be inspired to make a difference! 💡
