The Gulf of Maine subregion experienced warm conditions at the beginning of the year and during two short periods during summer and fall. Spring and fall tended to be cooler than average. The spring bloom in the Gulf of Maine began at about the same time as the recent term data suggests, but was of longer duration lasting well into May. The fall bloom was of short duration beginning and ending after and before the climatological starting and end dates, respectively. Spring zooplankton abundances were very low and summer and fall abundances were below or at the long-term means.
