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.
