Arctic Warming and Maine

Mar 1, 2017

Maine Boats, Homes & Harbors: Meltwater from both sea ice and shrinking glaciers and runoff from Arctic rivers swollen with increased rainfall have altered the ocean’s circulatory system. The long-term warming trend, and the rapid warming of the last 12 years, is likely related to the slowing of the AMOC, according to Pershing. 

“Notably for our region, it tends to shift the Gulf Stream north and weakens the Labrador Current, making the waters off of New England warmer,” he said. “This creates a chain of events that starts with melting in Greenland and the Arctic, leads to warming in the Gulf of Maine, and results in northward shifts in fish and lobster and declines in subpolar species like cod and shrimp.”
