CTD Observations in the Great South Channel during the South Channel Ocean Productivity EXperiment, SCOPEX, May-June 1989

摘要

CTD and acoustic Doppler current profiler (ADCP) observations were made in the Great South Channel (GSC) off the New England coast during R/V Endeavor cruise EN196 May 18 to June 12, 1989 as part of the South Channel Ocean Productivity EXperiment (SCOPEX). The primary objectives of the hydrographic measurement program were to observe and characterize the temperature, salinity, density, oxygen, fluorescence and light transmission fields and their spatial variability in the Great South Channel off the New England coast; resolve the low salinity surface plume-like structure usually observed east of Cape Cod in late spring; define the front or boundary between the vertically well-mixed water over Nantucket Shoals, the GSC, Georges Bank, and the stratified water in the deeper southwestern Gulf of Maine; and, characterize water properties in regions of enhanced biological productivity. The report presents a summary in graphic and tabular form of the hydrographic observations made during cruise EN196 on the R/V Endeavor.
