The Synoptic Ocean Prediction Experiment (SYNOP) was an ambitious, multi-faceted program focused on the dynamics and
predictailty of the Gulf Stream and its recirculations. The moored array component contained the arrays; one just downstream
of Cape Hatteras (the "Inlet Array"), one near 68°W (the SYNOP "Central Array") and one near 55°W ("SYNOP East") to which
this report is addessed. There were two settings of the SYNOP East array, the first, from fall 1987 to summer 1989, contained 42
current meters on 13 moorings straddling the mean axis of the Stream and extending north and south into the two recirculations.
The second extended the southernmost six moorings for an additional two years until summer 1991. Performance was excellent and
all instruments but one were recovered.
