Description:
Abstract:
In 2010 and 2011, the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC), collected bathymetry and acoustic-backscatter data from the outer shelf and slope offshore the Oceanside region in southern California. These data were acquired as part of the USGS Marine Geohazards Program. Assessment of the hazards posed by offshore faults, submarine landslides, and tsunamis are facilitated by accurate and detailed bathymetric data. The surveys were conducted using the USGS R/V Parke Snavely outfitted with a 100 kHz Reson 7111 multibeam echosounder. 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.

USGS-authored or produced data and information are in the public domain. Acknowledge 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:
Three USGS surveys were conducted over a 2-year period (PCMSC Field Activity IDs: S-11-10-SC, S-23-10-SC, and S-07-11-SC). The three surveys were conducted using a 100 kHz Reson 7111 multibeam echosounder. The 7111 is a horseshoe-shaped sonar that was mounted on the 34-foot USGS mapping vessel R/V Parke Snavely and affixed to a hull brace. Differentially Corrected Global Positioning System (DGPS) navigational data and measurements of vessel motion were combined in a CodaOctopus F190 inertial measurement unit (IMU) and passed to the sonar hardware and data collection software. Sound velocity measurements were collected continuously with an Applied Micro Systems Micro sound velocimeter (SV) deployed on the transducer frame for real-time sound velocity adjustments at the transducer-water interface. In addition, sound velocity profiles (SVP) were collected approximately every 2 hours throughout each survey day with an Applied Micro Systems. The navigation and vessel motion measurements were transmitted to the acquisition software in real time and combined with the instantaneous sound velocity measurements at the transducer head before each ping. The returned samples were projected to the seafloor using a ray-tracing algorithm working with the previously measured sound-velocity profiles in the acquisition software. Tide measurements relative to the North American Vertical Datum of 1988 (NAVD 1988) were downloaded from the La Jolla tide station 9410230. Original soundings were referenced to the World Geodetic System of 1984 (WGS 1984) relative to the North American Vertical Datum of 1988 (NAVD 1988).

Process_Step:
Process_Description:
Processed S7K files were imported to CARIS HIPS and SIPS bathymetry processing software for further cleaning and gridding. Field sheets were 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 appropriate field sheet. CARIS base surfaces were created for each field sheet at 5- and 20-m resolutions. The 20-m base surfaces included the entire survey area, while the 5-m base surfaces only included the shallower shelf and upper slope regions (water depth less than 200 m). The base surfaces were then exported as ASCII XYZ files (x-coordinate, y-coordinate, depth) in World Geodetic System of 1984 (WGS84, G1150) coordinates relative to the North American Vertical Datum of 1988 (NAVD-88). These data were gridded in Fledermaus (QPC) software (Version 7.1) at 5- and 20-m resolutions and the resulting surfaces were converted to ASCIIRaster format files and imported into a Geographic Information System (ESRI, ArcMap). Grids were projected horizontally to the North American Datum of 1983 (NAD83, CORS96) using the ESRI "WGS_1984_(ITRF00)_To_NAD_1983_CORS96" function in ArcTools. Finally, the separate 20-m resolution bathymetry surfaces were merged into one overall surface while the separate 5-m resolution surfaces were merged into one overall surface. This 5-m surface was also merged with in-shore bathymetry data collected as part of the California Seafloor Mapping Program and available at http://seafloor.otterlabs.org/.
