CURRENT - DIRECTION and Other Data from FIXED STATIONS From North Atlantic Ocean and Others from 1987-10-16 to 1990-06-16 (NODC Accession 9400108)

[From the May 1990 report, data/0-data/88-89/report89.txt]
The SYNoptic Ocean Prediction experiment (SYNOP) was undertaken with
the goal that increased understanding of the Gulf Stream obtained
through coordinated observations could be integrated with numerical
models, including predictive models of the Gulf Stream. Our moored
experiment, which began in fall of 1987, consists of two separate
arrays in the Gulf Stream as part of the SYNOP program. The "Inlet"
array of inverted echo sounders (IES) and deep current meters measure
key parameters that describe the variability of the Gulf Stream and
deep western boundary current (DWBC) near Cape Hatteras. In this
region the Gulf Stream first flows into deeper water and crosses over
the DWBC. The "Central" array of IESs, in a 350 km square centered
on the Gulf Stream near 68 W, monitors the thermocline structure of the
Gulf Stream in the region of large meanders and frequent interactions
with rings. The array also contains twelve tall current meter
moorings, that reach into the Gulf Stream core. Additionally most of
the IESs in the interior of the array are outfitted with bottom
pressure recorders (PIES).
