Fall 2007 Update: Subregion Comparison of Sea Surface Temperature

Charts of SST

Gulf of Maine SST during both late winter and spring time periods increased after a short multi-year run of cool conditions. Warming around the year 2000 resulted in SSTs in excess of 5°C during both time periods, changing to SST levels less than 4°C in the year 2004. A pattern coherent to the Gulf of Maine data is seen in the Georges Bank time series, but the pattern of SST change in the Southern New England and Mid-Atlantic Bight subregions is markedly different. There is an absence of a trend in the Mid-Atlantic Bight data suggesting that thermal patterns for the winter and spring periods may be distinct between the northern and southern segments of the ecosystem.
