Ocean current the windthe Coriolis effect plays a role in their behaviours. The thermohaline circulation is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. The adjective "thermohaline" derives from "thermo-" referring to temperature and "" referring to salt content, factors which together determine the density of sea water. Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. While the bulk
Fram Strait called the Atlantic water. The sub-surface flow has a strong seasonality with a minimal volume transport in winter. This current transports internal energy into the Arctic Ocean . The northward velocity is maximum in winter, so the "heat transport" is highest in winter. On the west side of the strait, the East Greenland Current flows southward on the Greenland Shelf. The current carries is relatively cold and fresh water out of the Arctic that corresponds to a water mass called Polar water. The Fram Strait area is located downwind of the Transpolar Drift and therefore covered by multi-year ice in
