Long Description:

More Information:
Understanding of the associations of plankton with hydrography and the role of physical characteristics (e.g., hydrographic structure, circulation) in determining the horizontal and vertical distribution of plankton and particulate matter has been hampered by our inability to describe plankton abundances at spatial and temporal scales comparable to physical measurements. The last decade has seen a surge in the development of high resolution, automated instruments for the description of the distribution of plankton. One such instrument, the Video Plankton Recorder, is essentially an underwater microscope that collects images of plankton and particles in a known volume at very high speeds (60 Hz) with coincident collection of environmental data. Automated or manual image recognition and data synthesis can be accomplished in near-real time at sea or post-cruise in the laboratory, yielding taxon or particle specific distributions at high spatial resolution. The instrument has been utilized on towed systems and as a stand-alone profiler in environments ranging from the Arctic and the Antarctic to Georges Bank and the Sea of Japan. Todays talk will focus on selected results from these studies
