Summary for Field Activity Number 1982-003-FA

Alternate Leg ID: 82-2

Area of Operations: Jobos Bay, Bahia de Jobos, South Coast of Puerto Rico, Puerto Rico, United States, Caribbean Sea, North America, North Atlantic

Dates: February 01, 1982 to February 18, 1982

Objectives: 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.

Type of Activity: Surveying, seismic and bathymetry profiling

Information to be derived: Samples and chemical analysis
Bathymetric maps
High-resolution seismic and bathymetry profiles

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.
