NE Channel Current Running Into Gulf Of Maine Measured At 57F - 11F Above Historic Spring Average
Canadian scientists have measured record-breaking temperatures in the deep water flowing into the principal oceanographic entrance to the Gulf of Maine, prompting concerns about effects on marine life.
The deep current entering the gulf via the Northeast Channel – a deep passage between the Georges and Browns banks – normally consists of chillingly cold water originating off Labrador and Greenland, and contributes to Maine’s unusually productive ocean waters.
But this month researchers working from the Canadian Coast Guard cutter Hudson recorded temperatures exceeding 57 degrees at depths of 150 to 450 feet – nearly 11 degrees above normal for this time of year and the highest seen in 15 years of surveys.
“It looks like there’s a big rush of warm water going into the gulf,” said David Hebert, a research scientist at the Bedford Institute of Oceanography in Dartmouth, Nova Scotia, which undertook the research. “It was really surprising.”
