Abstract:

The cruise with the title "Winter Sea Ice Study on Key Species" took place from August 14 to October 16, 2013 from Punta Arenas (Magellan Strait, Chile) to Cape Town (South Africa). Its main focus was to investigate the occurrence and behavior of the Antarctic krill in relation to biological and physical sea ice and open water conditions during the transition from austral winter to spring in the Scotia and Northern Weddell Sea.

Research groups came from biology, ice physics, geosciences, snow and atmospheric chemistry. Mineralogists from AWI and KIT investigated the formation of calcium carbonate in sea ice and related parts (snow, frost flowers). This presentation will give an overview about the cruise and preliminary results from the field work will be presented.
