Although much of the trench lies within the United States of America's Exclusive Economic Zone (EEZ), surprisingly few surveys have been conducted there during the past 25 years. This data set is a grey toned surface model image product derived from a process using multibeam bathymetry and acoustic-backscatter imagery data collected during the U.S. Geological Survey (USGS) science cruise 02051 in collaboration with the National Oceanic and Atmospheric Administration (NOAA) Research Cruise RB0208 from 24 September to 30 September 2002, Leg I of III. (Leg II and III: 20030218 to 20030407 and 20030828 to 20030904, respectively). This multibeam bathymetric image can be used in Geographic Information Science (GIS) to provide better perspective viewing and advanced analysis of geologic conditions in the Puerto Rico Trench. Remotely sensed features in the trench are studied and the information learned can be used to discern cause and effect of natural hazards such as earthquakes and tsunamis. en 20020924 20020930 ground condition Complete None planned -67.742288 -65.488916 20.293227 18.669185 -67.742288-65.48891618.66918520.293227 General Coastal and Marine Geology Program USGS National Oceanic and Atmospheric Administration U.S. Geological Survey CMGP NOAA Woods Hole Science Center WHSC NOAA Hydrographic Survey-Atlantic Branch NOAA Office of Ocean Exploration seafloor mapping field activity serial number 02051 field activity number RB02-08 NOAA Cruise RB0208 acoustic backscatter grey scale image Seabeam 2112 12-kHz Multibeam bathymetry oceans and estuaries imageryBaseMapsEarthCover ISO 19115 Topic Category geoscientificInformation General Puerto Rico Trench Caribbean Sea North America Atlantic Ocean Archipelago Muertos Trough Anegada Trough Antilles Arc Virgin Island Trough Caribbean Plate None Public domain data from the U.S. government are freely redistributable with proper metadata and source attribution.

The continued processing of data entailed reviewing and editing it with Caris Swath Edit, followed with Caris Sub Set mode editing. Both editing processes allowed the hydrographer to eliminate data points that were considered artifacts or out of context with the immediate benthic area. After editing, the weighted mean grid was re-generated with a grid resolution (s) from 300 to 30 meters. Lt Shep Smith NOAA/OMAO Hydrographer mailing and physical address
