Abstract:
This portion of the data release presents bathymetry data from the San Miguel Passage, in the Channel Islands, California. Bathymetry data were collected in the San Miguel Passage, Channel Islands, California in August 2007 by the U.S. Geological Survey, Pacific Coastal and Marine Science Center (USGS, PCMSC). Collection was accomplished using a 234.5 kHz SEA (AP) Ltd. SWATHplus-M phase-differencing sidescan sonar mounted on the NOAA, Channel Islands National Marine Sanctuary R/V Shearwater as part of the USGS research cruise S-2-07-SC. Data were collected in water depths up to 89 meters. The San Miguel Passage is within the Channel Islands National Marine Sanctuary and is the body of water between the two western-most islands of the chain - Santa Rosa and San Miguel Islands. The data were processed at the USGS, PCMSC to create a 2-meter resolution TIFF raster, presented here.
Purpose:
These data were collected to characterize seafloor substrate types in the nearshore waters southwest of Santa Rosa Island in the Channel Islands National Marine Sanctuary.
Supplemental_Information:
Additional information about the field activity from which these data were derived is available online at: http://cmgds.marine.usgs.gov/fan_info.php?fan=S207SC

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Estimated to be no less than 2 m, owing to water depth and total propagated uncertainties of the mapping systems, which include sonar system, position and motion compensation system, and navigation, as well as data processing that includes sounding cleaning, gridding, and datum transformations.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Estimated to be no less than 5 percent water depth, owing to water depth and total propagated uncertainties of the mapping systems, which include sonar system, position and motion compensation system, and navigation, as well as data processing that includes sounding cleaning, gridding, and datum transformations.

Process_Step:
Process_Description:
Data Collection: Bathymetry and acoustic-backscatter data were collected in 2007 using a 234.5 kHz SEA (AP) Ltd. SWATHplus-M phase-differencing sidescan sonar, mounted on the NOAA CINMS R/V Shearwater. Data were acquired and processed onboard using SEA Swath Processor (version 2.05) and SEA Grid Processor (version 2.05). Sound velocity profiles (SVPs) were collected with an Applied Micro Systems, SvPlus. The survey vessel was equipped with a dual antenna GPS compass and inertial attitude sensor: F180 Control Software (version 2.04), and the navigation application YONAV2 (version 1.19). GPS navigation data were post-processed with GrafNav (version 7.8) from Waypoint Navigation (NovAtel). Navigation data were processed in both forward and reverse.
Process_Date: 20070831
Process_Step:
Process_Description:
Data Gridding: The survey line files were imported into Caris HIPS and SIPS software (version 7.1.2), processed, filtered, and gridded into a 2-meter resolution base surface using the swath angle method. The base surface was exported as a TIFF file in UTM-10 coordinates referenced to the NAD83 ellipsoid. The TIFF file was imported into a Geographic Information System (Esri, ArcMap) and exported as a TIFF file with a TFW file defining the data’s geographic location and coordinate system.
