These bathymetry data were collected between 1998 and 2022 by National Oceanic and Atmospheric Administration (NOAA), United States Geological Survey (USGS), Monterey Bay Aquarium Research Institute (MBARI) California State University, Monterey Bay (CSUMB) and Ocean Exploration Trust (OET). Bathymetry data collected by institutions outside of NOAA are reference to overlapping NOAA hydrographic surveys using an average depth difference correction. The merged bathymetric surface resolutions varied by depth from 2x2m in <40m, 4x4m in 36 to 80 m, 8x8m in 72 to 160m, 16x16m in 144 to 320m and to 24x24m in >300m. They can be used to create high-resolution, nearly continuous coverage benthic habitat maps within the CINMS. Over the past 20+ years, sound navigation and ranging (SoNAR) surveys have mapped the seafloor within the Channel Islands National Marine Sanctuary (CINMS), a highly productive, oceanic region that extends from the Channel Islands coastlines to more than 1700m water depth. Once merged, these mapping surveys provide high-resolution, seafloor bathymetry with nearly complete coverage of an area greater than 3,800 square km (~1,470 square miles). The merged bathymetry surface can be used with ground truth data (bottom video, photography and samples) to produce spatially-continuous benthic habitat models across the entire CINMS to better predict and understand the wide variety and distribution of ecological communities found throughout the sanctuary bounds. These products are a direct output of the Southern California Seafloor Mapping Initiative and the Expanding Pacific Research and Exploration of Submerged Systems (EXPRESS) campaign. Their development was funded by the West Coast Deep Sea Coral Initiative, a 4 year regionally focused effort within NOAA’s Deep Sea Coral Research and Technology Program. These merged products are not intended to be used for navigation.

Single resolution geotiff raster surfaces were clipped into 5 depth ranges (0-40m depths, 36-80m depths, 72-160m depths, 144-320m depths and deeper than 300m depths) to match NOAA object detection multibeam coverage grid-resolution thresholds (NOAA HSSD, 2022) as a function of depth range (R code). These raster files were then resampled (ArcGIS) to the appropriate cell size resolution (i.e. 2x2m XY cell-size resolution for the 0-40m depth range, 4x4m XY cell-size resolution for the 36-80m depth range, 8x8m XY cell-size resolution for the 72-160m depth range, 16x16m XY cell-size resolution for the 144-320m depth range, and 24x24m XY cell-size resolution for the deeper than 300m depth range). We used resampling only to create coarser cell size raster data when possible. VR BAGs were filtered for the described 5 depth ranges (i.e. 0-40m depth, 36-80m depth, etc.) and exported to ascii XYZ files (CARIS Easy View). Ascii files were converted to point shapefiles (R code) and to single-resolution raster grids using Inverse Distance Weighted interpolation (ArcGIS). Interpolation was necessary instead of a data-binning sampling technique to convert VR BAGs into continuous, single-resolution raster surfaces without data gaps. These data gaps can be caused by varying cell-sizes within depth ranges within VR BAG data. For example, within the 0-40m depth range of a VR BAG, cell-size resolution can vary from 1-4m (although mostly within the 1-2m cell-size range in hydrographic data VR BAGs at these depths). Therefore, interpolation was required to convert these variable cell-sizes to a single-resolution cell-size, filling data gaps when sampling to a higher resolution (for example, 2m cell-size) than the coarsest cell-size resolution (for example, 4m cell-size) found within a given depth range (0-40m depths) of the VR BAG data. Bathymetry surfaces were spatially clipped to within the Channel Islands National Marine Sanctuary bounds (ArcGIS) and were projected to Universal Transverse Mercator (UTM) North Atlantic Datum 1983 (NAD83) Zone 10 North (10N) (ArcGIS) in the region of the 4 northern islands (San Miguel, Santa Rosa, Santa Cruz and Anacapa) and to UTM NAD83 Zone 11N (ArcGIS) in the Santa Barbara Island region. An average difference calculation was used to adjust bathymetry surfaces collected for non-hydrographic survey data to bathymetry surfaces collected by NOAA as hydrographic survey data (R code). Average difference depth values were applied to the non-hydrographic bathymetry data as a linear vertical shift across the raster data (R code). Merged bathymetry surfaces at cell-size resolutions 2m (0-40m depth), 4m (36-80m depth), 8m (72-160m depth), 16m (144-320m depth) and 24m (>300m depth) were created by merging the reference bathymetry surfaces (NOAA hydrographic surveys) with the adjusted bathymetry surfaces (non-NOAA hydrographic surveys) of matching resolution and depth range values (R code).

MBES and SBES sensors transmit acoustic sound, which is used to measure the depth of the seafloor. This is typically referred to as sonar (SOund NAvigation and Ranging). These depths can be used to understand spatial variability in seafloor morphologies and to map seafloor habitats.; Data Quality Method: Data quality levels vary across the bathymetric surfaces and depend on mapping agency, mapping purpose, sensors used and the time period when the data was collected.

Seafloor topography, bathymetry and other related geophysical data are usually managed and archived at the NOAA National Geophysical Data Center (www.ngdc.noaa.gov/mgg/). sonar sonar sound/sonic navigation and ranging Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. Side-scan sonar (also sometimes called side scan sonar, sidescan sonar, side imaging sonar, side-imaging sonar and bottom classification sonar) is a category of sonar system that is used to efficiently create an image of large areas of the sea floor.
