Other ID: 82-2
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Juan Luis Trias
Affiliate Investigator(s): Ramon Alonso - PR DNR, Chief Scientist
Data Type(s): Location-Elevation: Navigation, Seismics: Boomer, Seismics: Sparker, Sonar: Single Beam
Scientific Purpose/Goals: 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.
Start Date: 1982-02-01
End Date: 1982-02-18
Equipment Used: Raytheon DE-719 precision echo sounder, Boomer, Sparker , Motorola Mini-Ranger III, Single channel hydrophone
Information to be Derived:
Summary of Activity and Data Gathered: 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.
