Freshwater fluxes

Ocean receives freshwater by run-off from Asia north of the Himalaya. Large rivers carry freshwater from this enormous catchment area into the Eurasian shelf seas. Ocean waters with salinities below the average [...] balance of the Arctic Ocean. Such waters flow in from the Nordic Seas. An interchange of waters between the Arctic and the Nordic seas results in in seasaw fluctuations in fresh water content between the [...] Current and sea ice flux through Fram Strait. Inflow of saline water from the South is equivalent to a fresh water export. Fresh water from the Arctic strengthens the stratification in the Nordic Seas and the

We aim to reconstruct precipitation and sea surface temperature on decadal to millennial [...] southern hemisphere westerly wind belt (SHW) encircles Antarctica, tracking the mid-latitude meridional sea surface temperature gradient (e.g. Lamy et al., 2010 ). The SHW is an important component of global [...] understanding of the dynamics of the SHW and temperature evolution. To this end, we investigate a north-south transect of marine and lake sediment cores spanning the range of the SHW (Fig. 1). From these
