The R/V VenTresca is equipped with a Reson 8101 SeaBat multibeam sonar system. The 240 KHz SeaBat 8101 multibeam measures discrete depths, enabling complex underwater features to be mapped with precision. Dense coverage is achieved utilizing up to 3,000 soundings per second for a swath of up to 7.4 times the water depth. The SeaBat has a depth range of 1-300 m and can operate in either standard (150°) or wide (210°) mode when the ability to image shoreline or other features all the way up to the waterline is needed.
The Seafloor Mapping Lab (SFML) Data Library includes remotely sensed images (high-resolution multibeam bathymetry and side scan sonar geotifs), derived data (bathymetric contours, grid analyses), habitat classification data, associated data sets (survey footprints, coastline, NOAA charts), and FGDC metadata for 30+ locations along the California coast. Data archived since 2000.
