Description This part of the data release includes 25-m resolution merged multibeam-bathymetry data of the northern portion of the Southern California Continental Borderland. The data are presented as a TIFF file. In February 2016 the University of Washington in cooperation with the U.S. Geological Survey, Pacific Coastal and Marine Science Center (USGS, PCMSC) collected multibeam bathymetry and acoustic backscatter data in Catalina Basin aboard the University of Washington's Research Vessel Thomas G. Thompson. Data were collected using a Kongsberg EM300 multibeam echosounder hull-mounted to the 274-foot R/V Thomas G. Thompson. The USGS, PCMSC processed these data and produced a series of bathymetric surfaces and acoustic backscatter images for scientific research purposes. A 25-m bathymetric surface produced from this work was merged with publically available multibeam bathymetry data, as well as 2015, 2016, and 2017 multibeam bathymetry data collected in the continental borderland region by the Ocean Exploration Trust's Nautilus Exploration Program. The USGS, PCMSC processed the survey line files received from the Nautilus Exploration Program to include in the overall merged 25-m multibeam bathymetry surface of the northern portion of the Southern California Continental Borderland region that is available in this data release. These data can be used to assess the hazards posed by offshore faults, submarine landslides, and tsunamis as well as map sediment transport pathways and sedimentary sinks. [More]
