Need to cool off? ❄️Our wintering team celebrated 'Midwinter' at Neumayer Station III over the weekend. This means that, from now on, the days in Antarctica will become longer and brighter once again. The first half of the polar night is over!

Congratulations to AWI researcher Ulrike Herzschuh! The geographer has been endowed with three million euros by the European Research Council for her ‘plantExtinct’ project. She will be able to focus more on the extinction of plant species and develop new methods and models for this purpose.

Arctic sea ice reflects solar radiation, slows global warming and influences global ocean and atmospheric circulation. Due to limited observations, reanalysis data is used, which can be biased. A research team led by AWI researcher Akil Hossain has developed an AI model to correct these biases.

🥳Something to celebrate: 25 years of ecological time-series studies at the LTER Observatory HAUSGARTEN! As we see right now, it's not easy to sustain time series over long times -especially covering all spheres- yet it's vital to monitor #ClimateChange. @awi.de www.sciencedirect.com/science/arti...

Marine heatwaves in the Arctic are now more frequent, longer-lasting and more intense than in the past. A recent AWI study led by Marylou Athanase shows how these extreme events have changed significantly and where gaps in our knowledge still exist. www.awi.de/en/about-us/...

Since 2016, the AWI has operated an atmospheric observatory in Palau in the Pacific. The station measures ozone, water vapour, clouds and aerosols to help improve our understanding of atmospheric processes and refine climate models. www.awi.de/en/about-us/...

😊 I fondly remember the 'eek' moments we had after each visit to an ice floe to collect microplastic samples during #Polarstern expedition #PS126 in 2021 to our #Hausgarten observatory! 🚁During one flight, we discovered a small ‘boulder island’ in the ice & examined it more closely. 🎥 H. Jager 🧵->

What happens on the deep Arctic seafloor when glaciers retreat and sea ice disappears? A new AWI study reveals: As Arctic glaciers become increasingly unstable, more icebergs break off and drift through the ocean. Carrying rocks and sediment, these icebergs create new seafloor habitats as they melt.

Thawing permafrost, erosion and rising sea levels are causing permanent changes to Arctic river deltas. This puts important carbon sinks and unique ecosystems under increasing pressure. In a study, AWI researchers are investigating the impact of these changes on the Arctic and the global climate. 🌍

🚢 Yay, we’re setting sail soon: in July we’re heading to @awi.de HAUSGARTEN observatory in the #Arctic #DeepSea to continue our time series and take samples to assess the effects of #ClimateChange and #plastic pollution. Most of the boxes are packed, I can't wait to see the blue-white shades again!🤗

🪱 New study shows that meiofauna biomass and production decreased significantly from 2000 to 2017 at @awi.de HAUSGARTEN #observatory in the #Arctic #DeepSea. This may reflect growing competition with macrofauna. www.sciencedirect.com/science/arti...

New study finds 4.5 microfibers per clam (incl. #plastics) from #Antarctica and additives like #phthalates, #organophosphate esters & non-phthalate plasticizers (potentially from research activities). Several exceed levels reported for clams in other regions! www.sciencedirect.com/science/arti...

🐱🐶 New study shows that 🇪🇸 dog & cat dry food contain #microplastics. Dog food had over twice as many MPs (9.33 MPs/5g vs. 4.07 MPs/5 g). While dogs might be more vulnerable to systemic effects from MPs, cats may be more prone to chronic intestinal inflammation. www.sciencedirect.com/science/arti...
