Fall 2008 Update: Subregion Comparison of Sea Surface Temperature

Charts of SST

The recent trend of increasing winter and spring SSTs can be seen as a coherent trend in all four Northeast Shelf subregions, and it is also clear that the subregions experienced warmer conditions a decade ago. The winter and spring partitioning is based on the individual patterns of primary productivity in each subregion, so strictly speaking they are not directly comparable across regions. There appears to be a trend of increasing differences between the winter and spring SST in the Gulf of Maine, which is reflective of an increasing rate of warming occurring during spring. This reflects the earlier arrival of SST conditions which may affect the timing of migrations and biological interactions of predators and prey. There is little difference between the winter and spring SSTs on Georges Bank or in Southern New England.
