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

much do humans contribute to today's climate change? This is one of research's central questions. To give a proper answer, we have to know the parameters of natural variability, e.g. the temperatures in oceans, above the continents and in polar regions. This necessitates considering the properties of the climate of the past. We are able to reconstruct [...] world. In our research we link past climates to environmental conditions of the future. This implies that we research the state of the

The Antarctic Circumpolar Current is the planet’s most powerful and arguably most important. It is the only one to flow clear around the globe without getting diverted by any landmass, sending up to 150 times the flow of all the world’s rivers clockwise around the frozen [...] of years. But much is still not known about how it works, including how it might now respond to human-induced climate change.

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
