Other ID: 79-2
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): James V. A. Trumbull
Data Type(s): Location-Elevation: Navigation, Sampling: Geology, Seismics: Boomer
Scientific Purpose/Goals: Luquillo area - determine suitability of method and map potential sand deposit. Escollo de Arenas - collect sand samples, determine suitability of method and map potential sand deposit. Cabo Rojo area - collect sand and surficial samples in potential sand deposit area, to evaluate both method and sand deposit. Mayaguez area - complete bathymetry of Mayaguez-Boqueron area w/echo sounding. Aguadilla-Isabela area - collect surface samples and two profiles to supplement previous coverage and determine shallow structure of area being geologically mapped.
