Summary Information for Field Activity 1991-041-FA

Area of Operations: south coast of Puerto Rico, Caja de Muertos, Salinas, Jobos, Puerto Rico, United States, Caribbean Sea, North America, North Atlantic

Dates: November 06, 1991 to November 21, 1991

Chief scientist: Juan Trias

   Elazar Uchupi - WHOI

Objectives: Marine geologic maps of Puerto Rico Insular Shelf, Salinas to Jobos area and Caja de Muertos area by Trias and Uchupi, scale 1:40,000.

Type of Activity:

Information to be derived:

Summary: Approximately 200 nautical miles of shallow seismic reflection data were collected in the nearshore waters of Caja de Muertos and Salinas-Jobos to study sub-bottom profiles. More than 200 surface samples have been analyzed for textural and chemical qualities and to delineate the boundaries of the sediment facies. The results of this investigation will be published in the Marine Geologic Map of Caja de Muertos and the Marine Geologic Map of Salinas to Jobos area. The marine geologic maps will provide reconnaissance level information on bathymetry, geologic structure, surficial sediment characteristics and coastal processes. These maps will be part of a geologic mapping program covering the Puerto Rico insular shelf that is being carried out by the U.S. Geological Survey in cooperation with the Puerto Rico Department of Natural Resources.
