ecological role of marine mammals in the Arctic Ocean. Data stem from the interdisciplinary Arctic FRAM ocean observatory, which provides a unique opportunity to gain insight into these interrelationships [...] environmental alterations triggered by climate change, such as sea-ice decline.

data will help us to quantify the role of clouds in the lower Arctic atmosphere over the Northern Fram Strait. Similar to ACLOUD our strategy during AFLUX is to measure in, above, and below clouds with [...] weather maps from different prediction models showed that a cold-air outbreak began to evolve over Fram Strait. The maps predict that this outbreak will last over several days so that we can expect good [...] over sea ice was flown and combined cloud radar and drop sonde measurements followed over the open Fram Strait during the way back from North to South.

Since [...] we were happy that conditions were good enough to perform a flight over both the ice free part of Fram Strait but also over sea ice, this time up to 83° N. Moreover, strong wind is helpful for the turbulence [...] ideal and the cold air outbreak was still ongoing. We went first to a position west of Svalbard over Fram Strait, and followed then roughly the direction of convection rolls to the North. Such rolls mostly
