Atlantic inflow experiment, GIN Sea Cruise'86: Data report Part II: circulation

Abstract

As the initial field effort of the Atlantic Inflow Experiment, three instrumented moorings were deployed in the Faeroe-Shetland Channel during June 1986. The purpose of the array was to monitor the inflow, and to tract the movement of two subsurface floats deployed beneath the inflow in the sound velocity minimum at - 600 m. For this purpose a triangular array was deployed with two moorings placed within the main inflow stream and one on the western outflow side. Each mooring had two principal current meters at 125 and 230 m and a listening station at - 600 m. All three moorings performed well resulting in a -- 25-day time series of flow in the Channel to accompany the hydrographic cruise taken over the entire inflow area. The results of a drifting ARGOS meteorological buoy, placed within the array of current meters, is also included in this report. The data are presented in the form of time-series plots, progressive-vector diagrams, velocity stick diagrams,

and tables of statistics.
