The course describes the distribution of some chemical constituents in the Arctic and processes that can change their distribution, with main emphasis on carbon, methane, oxygen, and nutrients.
The Arctic Ocean and the continental shelves that surround it play an important role in the biogeochemical cycling of carbon, nutrients, and gases, such as carbon dioxide and methane, and will likely play an increasing role in the future if continued warming and sea ice loss occur. The cold waters of the Arctic are particularly sensitive to decreasing calcium carbonate saturation, which could have major consequences for both pelagic and benthic calcifiers. The role of sea ice in influencing fluxes of climate relevant gases and the effect of ice freezing and melting on chemical constituents in the ice and in the water column below is an essential part of the course. The fieldwork will be conducted by an ice-going research vessel.
