Description:
Abstract:
In December 2013 Scripps Institution of Oceanography (SIO) collected multibeam bathymetry and acoustic backscatter data in the Gulf of Santa Catalina and the San Diego Trough, southern California (SIO survey ID MV-1316). The surveys were conducted using the SIO R/V Melville outfitted with a 120-kHz Kongsberg EM-122 multibeam echosounder. The U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) processed these data and produced a series of bathymetric surfaces and acoustic backscatter images. 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. These metadata describe the bathymetry data provided in the report.
Purpose:
These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) or other software to identify bathymetric features. These data are not intended for navigational purposes.

Use_Constraints:

USGS-authored or produced data and information are in the public domain. Acknowledge Scripps Institution of Oceanography and the U.S. Geological Survey in products derived from these data. Share data products developed using these data with the U.S. Geological Survey. This information is not intended for navigational purposes. Read and fully comprehend the metadata prior to data use. Uses of these data should not violate the spatial resolution of the data. Where these data are used in combination with other data of different resolution, the resolution of the combined output will be limited by the lowest resolution of all the data. Although this Federal Geographic Data Committee-compliant metadata file is intended to document these data in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology.

Process_Description:
In December 2013, Scripps Institution of Oceanography (SIO) collected multibeam bathymetry and acoustic backscatter data in the Gulf of Santa Catalina and the San Diego Trough aboard the R/V Melville outfitted with a 120-kHz Kongsberg EM-122 multibeam echsounder (SIO survey ID MV-1316). The U.S. Geological Survey, Pacific Coastal and Marine Science Center received from SIO the raw (.all) survey line files. Survey line files were imported into Caris HIPS and SIPS software for processing. All surveying corrections including ship motion, water-column sound velocity, and tidal corrections are assumed to be incorporated into the raw (.all) line files prior to import into the Caris software. One field sheet was created to encompass the entire survey area. Survey lines were filtered to remove obvious erroneous soundings and soundings towards the noisier outer beams and then gridded into the field sheet. A CARIS base surface was created for the entire survey area at 25-m resolution using the CUBE processing method. The base surface was then exported as an ASCII XYZ file (x-coordinate, y-coordinate, depth) in World Geodetic System of 1984 (WGS84, G1150) coordinates relative to Mean Lower Low Water. There is a 0.058-m vertical difference between the NAVD-88 datum (1.389 m) and the Mean Lower Low Water datum (1.331 m) at the La Jolla tide station (9410230). These data were gridded in Fledermaus (QPC) software (Version 7.1) at 25-m resolution and the resulting surface was converted to an ASCIIRaster format file and imported into a Geographic Information System (ESRI, ArcMap) and converted to a GRID.
