Abstract
The global Thermohaline Circulation (THC), driven by fluxes of heat and fresh
water at the ocean surface, is known to be intimately involved with major
vanations tn the Earth' climate. The East Greenland Coastal Current (EGCC)
together with the East Greenland Current (EGC), represent the major surface
currents drawing fresh water southwards in the North Atlantic and therefore play
an important role in the THC. By identifying and quantifying Sub-Polar ocean
processes such as the EGC we can consolidate our knowledge on present-day
climate variability. To do so, hydro graphic data from cruise D298 was analyzed
and volume transport calculated. We found that the EGC (initially 8.3 Sv) and
the EGCC (initially 1.6 Sv), merge around Cape Farewell and that 2.2 Sv of
volume transport is lost in the process. We suggest that a certain volume of the
boundary currents is integrated into recirculation cells and that 2 2 Sv is
exported southward. Further work is needed on the fresh water fluxes to
investigate the exact quantity of fresh water exported from the EGC and EGCC
into the North Atlantic.
