Labrador Current Labrador Current The Labrador Current is a cold current in the North Atlantic Ocean which flows from the Arctic Ocean south along the coast of Labrador and passes around Newfoundland, continuing south along the east coast of Nova Scotia. It is a continuation of the West Greenland Current and the Baffin Island Current. It meets the warm Gulf Stream at the Grand Banks southeast of Newfoundland and again north of Outer Banks of North Carolina. The combination of these two currents produces heavy fogs and has also created one of the richest fishing grounds in the world. In spring and
North Atlantic Gyre warms. This is due to a weakening of the westerly winds, resulting in reduced wind stress and heat exchange, providing a greater period of time for the gyre water temperatures to rise. Collections of aerosols, marine particles, and ocean water in the North Atlantic Gyre from 1990-1992 have led to measurements in lead isotope ratios. These measurements exceed those associated with atmospheric pollution carried from Europe by the trade winds, implying that the majority of lead contamination in the gyre in the early 1990s was primarily caused by American emissions. The surface layers of the Sargasso Sea were used to
