The hydrological cycle of the Arctic Ocean has intimate and complex
linkages to global climate: changes in one affect the other,
usually with a feedback. The combined effects of large river
runoff, advection of meteoric water, low evaporation rates and
distillation by freezing contribute to the formation of a strong
halocline in the upper Arctic ocean, which limits thermal
communication between the sea ice and the warmer waters of Atlantic
origin below. Sea ice and freshened surface waters are transported
from the marginal seas by winds and currents, ultimately exiting
the Arctic Ocean through Fram and Davis Straits. Variations in the
freshwater outflow from these regions affect the density structure
of the Arctic Ocean itself and so the surface heat balance. Another
feedback is the effect these variations have on the density profile
of the water column in the Greenland and Labrador seas where, at
present, convection takes place mixing surface waters downwards
with those at greater depth. This downward convective motion
produces dense deep waters that flow outwards from these two
centres and affect the entire North Atlantic.
