Wind-driven transport occurs on nearly all of the world's continental shelves. A workshop, open to all interested scientists, was held in Portland, Oregon, on July 14-16, 1993, to assess the need for a major interdisciplinary study, and to begin defining the relevant questions and approaches. Specific questions were posed in the areas of air-sea feedback, sources and sinks of chemicals in the euphotic zone, plankton distributions and benthic exchanges. The consensus of the entire workshop was that a CoOP study of wind-drven transport processes should be made and should take place over the continental margin adjacent to the U.S. west coast. The central question to be addressed is: What processes control the cross-margin transport of biological, chemical and geological materials in a strongly wind-driven system? Some recommendations were made for locations and measurement techniques to be used in the envisioned two-year field program.
