Fin whales grow up to 27 meters in body length, almost as large as blue whales, but are much slimmer and lighter. A special feature is the asymmetrical colouring of the lower jaw: the right side is light, the left dark. Photo: Julia Hager Fin whales have been so...
The Greenland ice sheet has not been included in Arctic mercury budgets despite increasing annual meltwater discharge to the ocean and high mercury levels in Arctic organisms. The results of the current study are likely to change that. Photo: Dr. Michael Wenger...
Blue whales are the largest animals known to have existed, weighing up to 200 tons. With their rather coarsely bristled baleen, they filter the smallest animals such as krill and copepods from the seawater. In summer, a blue whale devours an estimated 40 million of...
Until now, scientists had not fully understood the strong increase in air temperature along the Antarctic Peninsula in recent decades. The new study now shows that apparently natural aerosols contribute significantly to the warming in the region. Foto: Julia Hager The...
