Fall 2007 Update: Trends in Spring Conditions for the Southern New England Subregion
The SST and chlorophyll data for the Southern New England subregion were partitioned into time period/seasonal indices following the scheme described in the Spring 2007 Ecosystem Advisory, see: http://www.nefsc.noaa.gov/omes/OMES/spring2007/adv6.html. The SST time series for Southern New England shows that the 2007 values continue the reversal of inshore cooling of the past five years. The 2007 winter SST index was above the time series trend whereas the spring index approximated the trend. Winter chlorophyll intensity and magnitude were slightly above the time series trend in this subregion. The 2007 spring bloom was the largest recorded in the time series in terms of both intensity and magnitude. The January-February zooplankton biomass estimate suggests a dramatic decline in zooplankton during the winter of 2007. Zooplankton data from March-April and May-June 2007 is not yet available.
