Sea Ice
The Arctic sea ice continues to dwindle: Since the 1970s, when satellites first began monitoring the white sheet covering the Arctic Ocean, its February extent was never as small as it was this [...] which are not only hitting the Arctic more frequently, but are also intensifying and reaching farther north.

Oldenburg and Potsdam, Germany have confirmed the existence of a new cryptic amphipod species in the North Sea. For the first time for the description of a new species, they used a level of mitogenomic information

coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, it can also become trapped in the sea ice that forms

creating user conflicts. The mooring of aquaculture facilities under the rough conditions in the North Sea is extremely costly. The high investment costs for such facilities would potentially make an ec

most important connections between the Arctic Ocean and the North Atlantic. In the past few years, we’ve seen a major decline in Arctic sea ice in the region. In addition, more warm and salty water is [...] extreme storms and changes in sea ice. Right now, I’m working with a regional climate model for the Arctic. The model consists of several components: the atmosphere, sea ice, ocean and land. Simulations [...] system components. For instance, we’ve recently begun using ice sheet models that provide insights into sea level variations. What fascinates me most are the feedback loops in the Earth system. Models allow
