Ecosystems Dynamics & Assessment : Current Conditions (Spring 2017)

Fall Temperature from the Survey

The thermal conditions at the bottom of the water column are extremely important in defining the habitats for the majority of resource species. Unlike sea surface temperatures that can be measured synoptically with satellite telemetry, bottom temperatures must be measured directly from ship surveys and other means. Thus, we often have incomplete spatial and temporal sample coverage to describe bottom temperature conditions. Recently, scientists at the NEFSC developed an interpolation approach that provides a more accurate depiction of spring and fall bottom temperatures. The time series of October time frame temperatures steadily increased over the past half century and in some ecoregions were the highest in this time series estimation procedure.
