The spatial and temporal variability of the East Greenland Coastal Current from historic data
Analysis of historic hydrographic data collected between 1932 and 1997 show a freshwater jet flowing southward along the East Greenland Shelf between Denmark Strait and Cape Farewell with a typical baroclinic transport of between 0.5 and 2 Sv. This jet has been labelled the East Greenland Coastal Cu...
