Estuarines, Bays, and Coastal Currents around Puerto Rico from 07 July 1970 to 21 August 1971 (NCEI Accession 7800495)

Three model 502 In-situ Current direction, temperature, and velocity meters, manufactured by Hydro Products in California were used simultaneously in a triangular pattern or in line. In some cases, all three instruments were used vertically at different depths.
A one half moon cycle period was taken for each station and a continuous recording was obtained for all three measurements. This data is shown by vectors every 10 degrees on a magnetic rose and in tabular form indicating the relative volume of water passing through the station every 10 degrees during the entire study period.
