Abstract: Hydrographic and chemical data were collected by the U.S. National Marine Fisheries Service's Woods Hole Laboratory from 1976 to 1987 under the leadership of David Mountain and Ken Sherman. This study was part of the Marine Resources, Monitoring, Assessment and Prediction (MARMAP) program. The program concerns both broad and fine scale studies of the physical-biological environment. The parameters included in this study were temperature, salinity, dissolved oxygen, chlorophyll, silicate, phosphate, nitrate, and nitrite. These data are recorded on a VAX magnetic disk at Woods Hole Laboratory, and a 9-track magnetic tape at the Woods Hole Oceanographic Institution.
