ABSTRACT:

Multibeam bathymetric data collected in the Puerto Rico Trench and northeastern Caribbean region are compiled into a 
seamless bathymetric terrain model for broad-scale geological investigations of the trench system. These data, collected 
during eight separate surveys between 2002 and 2013 and covering almost 180,000 square kilometers, are published here in 
large-format map sheet and digital spatial data. This report describes the common multibeam data collection and processing 
methods used to produce the bathymetric terrain model and corresponding data-source polygon. Details documenting the complete 
provenance of the data are provided in the metadata in the Data Catalog section.
