Marine Ecosystem - Greenland Waters (NW Atlantic Ocean) |
|||||||
Overview | Bering Sea | Barents Sea | Greenland North Atlantic Ocean temperatures respond to changes in the Arctic Oscillation, locally represnted by the North Atlantic Oscillation. When temperatures are warmer in northern Europe, they are often colder on the northwest Atlantic side. The figure below shows northwest Atlantic Ocean temperatures (Station 27) compared to the Kola temperature record in the Barents Sea (top figure, below). Note that when Kola temperatures (red) were warmer than normal, Station 27 temperatures (blue) were colder than normal. It is thought that local ecosystems may respond directly to temperatures or that temperatures may be a proxy for other oceanographic processes. In the 1980s, shrimp and other crustaceans replaced cod as a principal
catch in Greenland waters (bottom figure). Shrimp continue to thrive in
present climate conditions.
