While recognising the importance [...] player in the global carbon cycle. Ocean colour is also used to study export production: the fraction of primary production that is transported to the deep ocean. Ocean-colour data are also being used i [...] Other applications include studies of cross-domain fluxes and interactions: ocean-atmosphere and land-ocean fluxes of carbon, ocean-cryosphere interactions and climate impact on the polar ecosystems. It must

Yet the deep sea is not a habitat fully separated from the surface; it is already undergoing dramatic changes in response to warmer water, ocean acidification and environmental [...] the so-called mid-oceanic ridges – volcanically active mountain chains that usually extend one to three kilometres above the seafloor and can be found in all (of) the world’s oceans. With a total length [...] standards. For another, food is harder to come by. The central Arctic Ocean is largely covered with ice and – unlike the Antarctic’s Southern Ocean – surrounded by landmasses. Exchanges with the Atlantic and Pacific

Besides water temperature increase, expanding ocean acidification will pose another threat to pelagic and benthic life in the Arctic Ocean (e.g. Bates et al., 2009; Lischka & Riebesell, 2012; AMAP [...] Changing Arctic Ocean) focusses on the plankton community and the microbial processes relevant for biogeochemical cycles of the Arctic Ocean. This research focus is acknowledging that the Arctic Ocean has gained [...] In addition, the chemical equilibrium and the elemental cycling in the surface ocean will alter due to ocean acidification. These environmental changes will have consequences for the biogeochemistry and

Stefan Hendricks) The Arctic Ocean Unlike at the southern tip of the planet, in the High North there is no continent, only an ocean. These waters, also known as the Arctic Ocean, extend to the northern coasts [...] Arctic Ocean is the smallest in the world. Moreover, it’s not particularly deep: just 987 metres on average, though 5,669 metres at its deepest point. Its only deep-sea connection to other oceans lies in [...] freshwater is flowing into the Arctic Ocean. This freshwater lies like a lid atop the deeper, saltier water layers. As a result, fewer nutrients from the ocean’s depths rise to the surface, while less
