| Merged multibeam bathymetry--Catalina Basin and northern Gulf of Santa Catalina, southern California | bathymetry | This part of the data release includes 10-m resolution merged multibeam-bathymetry data of Catalina Basin and northern Gulf of Santa Catalina. 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 10-m bathymetric surface produced from this work (available in this report) was merged with re-processed 10-m resolution multibeam bathymetry data collected in the Gulf of Santa Catalina in 2013 by Scripps Institution of Oceanography and processed by USGS, PCMSC (available at, https://pubs.usgs.gov/sim/3324/). 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. | Peter Dartnell |
