Spring 2015 Update: Conditions of the Northeast Shelf Ecosystem

Fall Sea Surface Temperature - Northeast Shelf Ecosystem

The Northeast Shelf Large Marine Ecosystem experienced above average sea surface temperatures (SSTs) during the fall of 2014 after a period of cooling in some parts of the ecosystem seen during spring. 

In each graph, the long term mean SST is shown as a dark gray line with areas representing plus and minus one and two standard deviations of the mean as progressive shades of gray, respectively. SSTs for 2014 that were above the mean are shown in red and below the mean in blue.

Though all areas show above average summer into fall temperatures, SSTs were well above the mean in the northern end of the ecosystem as seen in the Gulf of Maine, Georges Bank, and Scotian Shelf subareas (see figures). Many days were above the mean by more than two standard deviations in these areas. SSTs were at or below the long term means during last winter and into spring in the Middle Atlantic Bight and at the long term mean during the summer.
