| Fig. 7. a) Seasonal changes in the standing stock of zooplankton for four areas of the Northeast shelf ecosystem--the Gulf of Maine, Georges Bank, southern New England, and the Middle Atlantic Bight. Values are based on mean monthly volumes in cubic centimeters per 100 cubic meters of water and include the range and standard error of the mean. b) Seasonal pulses in abundance of the dominant copepods--Calanus finmarchicus, Pseudocalanus minutus, and Centropages typicus--in four areas of the Northeast shelf ecosystem are shown. | |
