The dramatic loss of ice in the Arctic is influencing sea-ice transport across the Arctic Ocean. As experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research report in a new study, today only 20 percent of the sea ice that forms in the shallow Russian marginal seas of the Arctic Ocean actually reaches the Central Arctic, where it joins the Transpolar Drift.
There is a wide variety of animals living on the Arctic seabed. Attached to rocks, they feed by removing nutrients from the water using filters or tentacles. But it can take decades for these colonies to become established, and they probably don’t achieve their natural diversity until much later. These are the findings of a unique 18-year study by researchers from the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI), which has now been published in the scientific journal “Limnology and Oceanography”.
Not all of the CO2 generated during the combustion of fossil fuels remains in the atmosphere. The ocean take up considerable quantities of these man-made CO₂ emissions from the atmosphere. Without this sink, the concentration of CO2 in our atmosphere.
A few days ago, the captain and the head of the current Polarstern expedition jointly decided to abandon their efforts to reach the Larsen C Ice Shelf. Since dense sea ice and ice ridges blocked the planned route, the ship has now set course for alternative research sites further to the north.
On the evening of 6 March 2019, His Majesty King Willem-Alexander and Her Majesty Queen Máxima of the Netherlands will visit the Alfred Wegener Institute as part of their tour of the State of Bremen. Dutch and German researchers will report to the royal couple on their collaborations regarding climate change, biodiversity and nature conservation, sign a joint declaration, and subsequently gather for a festive dinner.
