Alternate names 82-2
Purpose 1. PR DNR contract from Puerto Rico Electric Power to survey possible channel areas of Bahia de Jobos for possible dredging in the near future of deep channel for coal freighters. 2. Make seismic and bathymetry profiles with highest possible resolution.
Location Jobos Bay, Bahia de Jobos, South Coast of Puerto Rico, Puerto Rico, United States, Caribbean Sea, North America, North Atlantic;
Summary R/V JEAN A served as base and hotel depot. R/V RACHEL CARSON was used for surveying with an additional 14-ft. outboard for shallow water surveying. The first four days were used to set gear and transponder stations in a very rough country area. The surveying time for each day was short due to bad weather in the area (rough seas and strong winds). Estimated total length of seismic lines: 20 nm.
Comments Original Center People field contained: Juan Luis Trias, Geologist; James Trumbull, Scientist; Rusty Tirey, Woods Hole, MA, scientist; Dave Nichols, Woods Hole, MA, electronic technician.
