Fall Sea Surface Temperature - Northeast Shelf Ecosystem
The Northeast Shelf Large Marine Ecosystem experienced above-average sea surface temperatures (SSTs) during the fall of 2015, after a period of below-average temperature during spring. In each graph the long-term mean SST is shown as a dark gray line, with areas representing plus and minus 1 and 2 standard deviations of the mean as progressive shades of gray, respectively. SSTs for 2015 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 2 standard deviations in these areas. SSTs were at or just above the long-term means during October of last year in the Middle Atlantic Bight and Gulf of Maine, representing the only temperature moderation during the fall season.
