Field Activity 1979-025-FA

Identifier 1979-025-FA
Alternate names 79-6
Purpose Measure currents over Escollo de Arenas, a large sand body northwest of Vieques, Puerto Rico.
Location Escollo de Arenas, Isla de Vieques, Puerto Rico, Caribbean Sea, United States, North America, North Atlantic;
Summary Owing to last minute changes in the scientific party, the cruise went off with a bare minimum of personnel. The crew of the R/V JEAN A, however, freely offered their assistance and the offer was gratefully accepted. Their help greatly increased the amount of data we were able to collect in the short time we were out. Tides over the escollo are semidiurnal. Current drogue studies conducted during daylight hours monitored water velocities between low flood and low ebb maximums for 3 consecutive days (8/21 - 8/23). On the 23rd, the JEAN A anchored over the middle of the escollo and monitored currents at a stationary site using a hand-held current meter with deck readout. Current drogue data: 3 days; Hand-held current meter data: 1 day.
