Fall 2007 Update: Gulf of Maine Subregion
SST conditions were warm in the Gulf of Maine subregion during the fall of 2006 into the winter of 2007. The spring 2007 temperatures were both above and below the long term mean. The 2007 spring bloom was above the climatological mean in both its intensity and magnitude. The bloom started at a date typical of the spring bloom in that subregion, but lasted slightly longer than usual. Early summer chlorophyll concentrations were at an average level. The winter 2007 zooplankton biomass for the Gulf of Maine continues a trend that began in fall 2006 of lower than average zooplankton biomass. The January-February zooplankton estimate is provisional.
