Spring 2007 Update: Long Term Temperature-Area 1 (Gulf of Maine)

Index area 1 of the long term ERSST dataset overlaps most of the Gulf of Maine with the exception of the eastern portion of the Gulf. The annual mean SST for area 1 during 2006 was 10.1°C which is greater than the long term mean of 9.4°C, but still less than the maximum of the time series of 10.9°C. SSTs were higher during the mid-century warming period of the 1940s, and nearly as high as the beginning of the time series. Winter-summer temperature difference has been increasing during the last few decades, which has been interpreted as an effect of climate change. The winter-summer difference was 13.2°C in 2006, which is greater than the long term mean of 12.3°C, but still less than the maximum difference of the time series of 14.3°C. Finally, the fall SST index for this area is patterned similarly to the annual mean with a value of 10.2°C in 2006, which is greater than the long term mean of 9.5°C, but still less than the maximum of the time series of 11.3°C.
