It is well known that plankton abundance is highly variable over a broad range of scales. Conventional
sampling with nets, pumps, and bottles is discrete and covers only a small portion of the total variance
spectrum. Development of the Video Plankton Recorder (VPR) has enabled us to quantify the abundance of
seston and plankton, including delicate taxa, over a range of scales from centimeters to hundreds of
kilometers. During the 1994}1995 GLOBEC Georges Bank "eld years, three VPR surveys were conducted
across the bank from the Slope Water in the south to the Gulf of Maine in the north, a distance of &200 km.
The surveys, conducted in June 1994, January 1995, and March 1995, intersected at least four distinct water
types (Slope Water, strati"ed bank water, well-mixed bank water, Gulf of Maine water) and crossed several
