Massive marine heatwave strikes the northeastern Pacific •

Today’s Image of the Day from NASA Earth Observatory shows a massive marine heatwave in the northeastern Pacific Ocean in August of 2019.

Red colors represent areas that were hotter than average, while blue-colored areas were colder than average. 

A team at Coral Reef Watch created the map by combining data from the Suomi NPP, MTSAT, Meteosat, POES, Terra, Aqua, and GOES satellites with computer models.

The unusually warm water will impact marine ecosystems and regional fisheries. 

Nicholas Bond is a climatologist and research meteorologist at the University of Washington.

“I would not be surprised if the class of salmon that went to sea this year have relatively low survival rates,” said Bond. “Many of us in the climate and fisheries – oceanography community along the West Coast and in Alaska are watching what is happening with great interest – and at least some trepidation.”

This region is still recovering from a similar event that persisted from 2014 to 2016.
