the focus of the section lies in the pelagic and benthic communities of the North Sea, with comparisons to other shelf sea systems. Given the large temporal and spatial spectra we work on a range of [...] Short Profile Coastal seas are highly variable environments, with variation on all time scales from seconds to decades, and spatial scales from mm to km. Organisms living in such zones should be adapted [...] large variation, but potentially not to the changes that are currently taking place in our coastal seas. Thus, coastal organisms represent the ideal case to contrast the effects of natural and non-natural

Molecular Sea Ice Ecology Polar oceans are seasonally covered by sea ice with an average size of the continent of North America. Despite harsh conditions therein, sea ice and its lower surface can carry [...] typically dominated by Diatoms. Sea ice can provide important primary production to polar oceans via these communities, although they are often very patchy. In times of declining sea ice coverage it is a major [...] major challenge to determine current sea ice biodiversity, functions provided by its biota, and the future of sea ice communities in a warming ocean. We address these questions through analyses of total

During strong glacials, it reached [...] which helps us to reconstruct past ocean currents from the iceberg drift. The Barents Sea - the ocean basin north of Scandinavia - was subaerially exposed until ca. 1 million years ago. The thick SBSIS [...] South, and Frans Josef Land and Novaya Zemlya towards east and southeast, reaching even into the Kara Sea. The thick ice mass shaped the buried landscape and left traces at many locations. Today, we are able
