Working in the Arctic Fram Strait, scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have found microplastic throughout the water column [...] microscopically small plastic particles into the region between Greenland and Spitsbergen from both the Arctic and the North Atlantic. While passing through the Strait, many particles eventually drift to the

Tiny gypsum crystals can make phytoplankton so heavy that they rapidly sink, hereby transporting large quantities of carbon to the ocean’s depths. Experts from the Alfred Wegener Institute [...] Institute recently observed this phenomenon for the first time in the Arctic. As a result of this massive algal transport, in the future large amounts of nutrients could be lost from the surface waters.

After eventful and busy months, the Arctic season ends this weekend with the Polarstern expedition called ArcWatch-1. The team of almost 100 crew and scientists measured sea ice thickness and properties [...] properties, recorded the currents and chemical properties of the ocean and investigated life in and under the ice, in the open water and at the bottom of the deep sea.

In addition, more warm and salty [...] regional climate model for the Arctic. The model consists of several components: the atmosphere, sea ice, ocean and land. Simulations with this model help us interpret the Arctic climate, its variability and [...] climate changes in the Arctic are connected to the weather and climate in central Europe. The difficult thing about these interactions is the fact that, in addition to the Arctic factors, other aspects

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 [...] 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; the remaining 80 percent of the young [...] development not only takes us one step closer to an ice-free summer in the Arctic; as the sea ice dwindles, the Arctic Ocean stands to lose an important means of transporting nutrients, algae and sediments
