Description:The primary objective of the cruise was to collect standardized samples and data to monitor changing biological and physical properties that influence the sustainable productivity of the living marine resources of the Georges Bank and Gulf of Maine portions of the Northeast Continental Shelf ecosystem. Four secondary objectives of the cruise included:
1. An investigation of overwintering populations of Calanus finmarchicus in the Gulf of Maine to determine their metabolic state and lipid reserves, and to ascertain whether this population is augmented by sources from outside this region.
2. Analysis of phytoplankton samples for nitrogen and carbon stable isotope ratios by filtering the discharge water of the flow-through instrumentation at 12 locations on this leg of the survey.
3. Examination of sample jars for the presence of large numbers of Calanus finmarchicus to correlate with right whale sightings received by the Right Whale Sighting Network Coordinator in Woods Hole.
4. Analysis of zooplankton spatial and temporal variability in the variation of gene frequency in copepods and euphausids from ten stations selected randomly from the 61 stations of the survey.
