Gulf of Maine is Warming Faster than 99.9% of Ocean Waters

According to a 2015 study by the Gulf of Maine Research Institute, the waters of the Gulf of Maine, which stretch between Cape Cod and Nova Scotia, are warming faster than 99.9% of the world’s oceans.  Rising 3 degrees celsius in the last decade alone, the waters of the Gulf of Maine are rapidly becoming a focus for scientists interested in studying the effects of future climate change right now in a real world setting.  It’s a local test of what is likely to come globally.

Impacts on marine life include:

  • The cod fishery that was over-fished for decades currently stands at only 4% of sustainable levels and has not rebounded as expected despite an effective moratorium on cod fishing in the Gulf
  • Lobster populations and harvests are at an all-time high due to the warmer water and lack of cod predators
  • Local species are moving north and into deeper water and new populations of black sea bass, green crabs and long fin squid are showing up on the Maine coast
  • Phytoplankton concentrations are 25% of what they were a few decades ago.  As an important foundation of the food chain, this bodes ill for marine life generally.

The cause of the recent temperature rise seems to be a reduction of cold deep water entering the gulf from Newfoundland and Greenland due to the global warming induced rapid ice melt occurring there which is changing cold water currents.
