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

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
