Oceanus cruise 445.
The research objective is synoptic mapping of Alexandrium fundyense, hydrography, and velocity in the coastal current from Cape Cod to Georges Bank. Dr. Dennis McGillicuddy, Jr., Chief Scientist.

Researchers Jefferson Turner of UMass Dartmouth, left, foreground, Dennis McGillicuddy of WHOI (green jacket), and winch operator John Gaylord of WHOI, above, deploy a CTD rosette system on R/V Oceanus to measure water properties and collect samples during a voyage studying a harmful algal bloom, or ?Red Tide," in the Gulf of Maine. Researcher Stacy Lee of Northeastern University (yellow jacket) looks on. Toxins from the dinoflagellate Alexandrium fundyense can accumulate in filter-feeding organisms such as mussels and clams, causing illness in humans if the contaminated shellfish are consumed. Fortunately, effective monitoring by state agencies protects human health by closing the affected shellfish beds to harvest. Research by this group, under the auspices of NOAA and the NSF/NIEHS Woods Hole Center for Oceans and Human Health, is leading to a better understanding of the toxic blooms, providing valuable information for management and mitigation of this problem.
