This week: The atmosphere is an important component of Earth's climate system and a key science focus area of the MOSAiC expedition. Learn more about this thin veneer of gases and other things that is crucial to our survival. Also, we answer your questions about what happens when someone on the Polarstern gets sick.

This week: MOSAiC Leg II is coming to an end as the Russian support icebreaker Dranitsyn is making its way to the Polarstern with Leg III participants. Also, a furry midnight visitor was caught on camera, and MOSAiC team members answer three of your questions! Photo credit: AWI

MOSAiC team members Michael Gallagher (CIRES & NOAA) and Taneil Uttal (NOAA) were on site fixing the ASFS (atmospheric surface flux station) at MOSAiC's L3 site when they heard the ice making noises. This station is in a very dynamic location, with local ice movements, cracks, and open water, all of which are important to measure and understand. But alas, those ice dynamics can also pose a big challenge for operations.

The high albedo of sea ice and low albedo of ocean water can lead to interesting changes in Earth's climate system - this week, learn about the ice-albedo feedback. Also, MOSAiC scientists answer your questions about living in darkness and cracks in the ice. Figure credit: AWI

This week: Learn about an important component of Earth's energy budget with a fancy name: ALBEDO. And, MOSAiC scientist Julienne Stroeve answers your question about how heavy scientific equipment on the ice is. Also, submit your artwork to the new Museum of MOSAiC Art!
