Icebergs bringing nutrients into the ocean to fertilize their surroundings is evident by the fact that penguins, marine mammals and seabirds often can be seen around the icy giants. Otherwise, iron-rich dust fertilizes the Antarctic Ocean. But that was not always the...
During the warming after the last glacial maximum, there were repeated periods when masses of icebergs broke off in Antarctica, leading to global sea level rise over many hundreds of years. Photo: Dr. Michael Wenger Since the last ice age about 20,000 years ago, there...
Norcemgrotta in the municipality of Narvik is one of the two caves that the research team is examining for traces of prehistoric animals. Photo: Marius Robu Archaeological evidence of high latitude wildlife from before the last ice age is extremely rare due to erosion...
Fossil teeth from extinct steppe bison and wild horses provided scientists with clues as to why these large grazers became extinct in the Arctic. Photo: Andrew Higley/UC Creative + Brand In the ice-age mammoth steppe, which shaped the landscape of what is now northern...
During glacial periods, the sea level falls, because vast quantities of water are stored in the massive inland glaciers. To date, however, computer models have been unable to reconcile sea-level height with the thickness of the glaciers. Using innovative new...
