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

planned open-ocean infrastructure FRAM (FRontiers in Arctic marine Monitoring) is permanent presence at sea, from surface to depth, for the provision of near real-time data on Earth system dynamics, climate [...] and ecosystem change. The FRAM Ocean Observing System will be installed in the gateway between the North Atlantic and the Central Arctic, representing a highly climate-sensitive and rapidly changing region [...] towards a better understanding of the effects of change in ocean circulation, water mass properties and sea-ice retreat on Arctic marine ecosystems and their main functions and services. FRAM will implement

Over centuries the deep sea was considered as a vast, desert-like environment with low number of species. However, in recent years knowledge about biodiversity in the deep sea has started to increase and [...] life. Biodiversity in the deep sea depends among other parameters on water depth, which in turn is linked to food availability. In contrast to the past assumption that deep-sea organisms live in very stable [...] changes in a the transition zone between the northern North Atlantic and the central Arctic Ocean, and to determine the factors controlling deep-sea biodiversity, the Alfred Wegener Institute established

[...] Flatfish and shrimp are caught in the North Sea by using trawls that are dragged across the seabed. This releases carbon into the water and carbon dioxide (CO2) into the atmosphere, as shown by the latest
