摘要

During 1991, a collaborative program between the United States and Barbados wasestablished with the support of NOAA's Climate and Global Change Atlantic Climate Change Program, to conduct regular measurements of the transport and water mass characteristics in the major southern passages to the Caribbean Sea. This program involves the use of a Barbados Coast Guard vessel, the HMBS Trident, which makes routine monthly patrols in the area and has been equipped to collect standard hydrographic measurements (CTDO2 profiles and water samples) and velocity profile measurements using a downward-looking acoustic Doppler current profiler (ADCP). The purpose of the program is to determine the quantity and time-variability of South Atlantic surface, thermocline, and intermediate waters flowing into the North Atlantic in compensation for southward cross-equatorial transport of North Atlantic Deep Water, and to establish an economical means for future monitoring
