A new overview study has now shown that wind [...] the Institute for Advanced Sustainability Studies in Potsdam, and the GEOMAR Helmholtz Centre for Ocean Research in Kiel – describes how microplastic finds its way into the atmosphere and how it is subsequently

To prove if they [...] leads and polynias For the energy and moisture exchange between the atmosphere and the ice covered ocean, leads and polynias play an important role. This is documented by many modelling studies, but only [...] sea ice have a significant effect on the energy exchange between the atmosphere and the ice covered ocean. Uncertainties in the representation of sea ice albedo contribute considerably to the differences

Massive sponge gardens thrive on top of seamounts in the Central Arctic Ocean, one of the most oligotrophic seas on Earth. They appear to feed on the remnants of an extinct fauna.
