Spring Sea Surface Temperature - Northeast Shelf Ecosystem
The Northeast Shelf Large Marine Ecosystem experienced average to below average sea surface temperatures during the spring of 2017 following the trend of above average temperatures seen during fall into winter seasons. In the graphs spanning the last half of 2016 and first half of 2017, the long-term mean sea surface temperature (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 (see figure). SSTs below the long term mean are shown in blue, above the mean in red. The Middle Atlantic Bight and Georges Bank would appear to have been slightly cooler then the Gulf of Maine, but overall, the Northeast Shelf ecosystem was at or near long term mean sea surface temperatures for much of the spring period.
