South Channel Ocean Productivity Experiment; Hydrography; Endeavor (Ship: 1976-) Cruise EN196Abstract
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). These observations were obtained using several sampling plans
- a series of small-scale surveys in support of biological sampling and a large-scale survey
of five cross-channel transects extending from Nantucket Shoals and the coast of Cape
Cod to Georges Bank. The maximum sampling depth at each station was within a few
meters of the bottom.
The primary objectives of the hydrographic measurement program were to a)
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, (b) resolve the low salinity surface plume-like structure usually observed
east of Cape Cod in late spring, (c) 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 (d) characterize water properties in
regions of enhanced biological productivity. This report presents a summary in graphic
and tabular form of the hydrographic observations made during cruise EN196 on the
R/V Endeavor.

Interannual variability of the South China Sea throughflow inferred from wind data and an ocean data assimilation product
Wang, Dong Xiao; Liu, Qinyan; Huang, Rui Xin; Du, Yan; Qu, Tangdong (American Geophysical Union, 2006-07-26)The Luzon Strait transport, as an index for the South China Sea throughflow, has attracted much attention. In this study the interannual variability of the Luzon Strait transport is examined, using the Island Rule and ... -
