of the Canadian Beaufort Sea, we know little about the distribution of submarine permafrost for most of the shallow Arctic Shelf, over 80% of which lies offshore of Eastern Siberia. Degradation rates of the ice-bearing permafrost following inundation have been estimated [...] atmospheric greenhouse gas concentration. We need to know more about the current distribution and state of permafrost beneath the ocean, about what cause sit thaw, where and how quickly. This group

oldest ice, with which we can reconstruct the climate of the past, more than one million years ago? For all of these questions observations on site are essential. This begins with the determination of the ice thickness, continues with the inference of the crystal orientation fabric in larger depth and ends with the composition of the subsurface below the ice, both of which govern flow behaviour of ice. In the end, we hope to make conclusions about how ice masses

Fascinating discovery
Near the Filchner Ice Shelf in the south of the Antarctic Weddell Sea, a research team has found the world's largest fish breeding area known to date. A towed camera system photographed and filmed thousands of nests of icefish of the species Neopagetopsis ionah on the seabed. The density of the nests and the size of the entire breeding area suggest a total number of about 60 million icefish breeding at the time of observation. These findings provide support for the establishment of a Marine Protected

Antarctic Peninsula
During the era of commercial whaling, fin whales were hunted so intensively that only a small percentage of the population in the Southern Hemisphere survived, and even today, marine biologists know little about the life of the world’s second-largest whale. That makes the findings of researchers from the Alfred Wegener Institute, Helmholtz [...] . In view of this, the marine biologists call for protective measures for this important habitat so as not to jeopardise the apparent recovery of
