Satellite SST Standard Deviation Trends for the Northeast Shelf Ecosystem

Climate change involves not only the change in level of climate parameters, it also involves change in system variability that can be seen in more dramatic shifts in weather in terrestrial systems and in ocean parameters on the Northeast Shelf. In an examination of daily sea surface temperatures in the NE Shelf ecosystem, system variability has increased as evidenced by the increase in the annual standard deviation of sea surface temperature. For example, for the NE Shelf as a whole, daily temperature standard deviation has gone from approximately 4.9 to 5.6 over the time period, indicating organisms have experienced greater day to day temperature excursions.
