Fall Sea Surface Temperature - Northeast Shelf Ecosystem
The Northeast Shelf Large Marine Ecosystem experienced above average sea surface temperatures (SSTs) during the fall of 2017 after a relatively cool spring in most ecoregions. 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, or moderately and well above the long term mean, respectively, as progressive shades of gray, respectively. SSTs for 2016 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 and Scotian Shelf and only moderately above average in the and Middle Atlantic Bight subareas (see figures below). Many days were above the mean by more than two standard deviations in these areas.
