“Blue Blob” Cools North Atlantic
A region of cooling water in the North Atlantic Ocean near Iceland, nicknamed the “Blue Blob,” has likely slowed the melting of the island’s glaciers since 2011 and may continue to stymie ice loss until about 2050, according to new research.
The origin and cause of the Blue Blob, which is located south of Iceland and Greenland, is still being investigated. The cold patch was most prominent during the winter of 2014-2015 when the sea surface temperature was about 1.4 degrees Celsius (2.52 degrees Fahrenheit) colder than normal.
