Description:
Abstract:
This polygon shapefile describes the data sources used to create a composite 30-m resolution multibeam bathymetry surface of southern Cascadia Margin offshore Oregon and northern California.
Purpose:
In 2018 and 2019 the NOAA ships Rainier and Fairweather collected multibeam bathymetry data in 5 areas along the southern Cascadia Margin as part of a cooperative project between the U.S. Geological Survey, Pacific Coastal and Marine Science Center and NOAA. These regions were combined with other publicly available multibeam bathymetry data. The surface was generated to assist research projects studying offshore geohazards including mapping faults, submarine landslides, sediment transport pathways, and seafloor seeps. This shapefile describes the sources used to create the composite multibeam bathymetry surface. These data are not intended to be used for navigation.

Process_Description:
The Ocean Exploration Trust's, Nautilus Exploration Program collected multibeam echosounder data along the southern Cascadia Margin between 2016 and 2020 (OET survey ID's NA072, NA078, NA080, NA082, and NA122). The U.S. Geological Survey, Pacific Coastal and Marine Science Center requested and received both raw line files and processed grids (these data are now available from NOAA, National Centers for Environmental Information, https://ngdc.noaa.gov/mgg/bathymetry/multibeam.html). Raw survey line files were imported and processed in Caris HIPS and SIPS software (version 11). The data were gridded into 30-m surfaces and exported as geoTIFF's or ASCIIRaster files and imported into ArcMap.
Process_Date: 2020
Process_Step:
Process_Description:
Publicly available multibeam echosounder data available from NOAA, National Centers for Environmental Information were downloaded from https://ngdc.noaa.gov/mgg/bathymetry/multibeam.html.

A processed multibeam bathymetry grid from Monterey Bay Aquarium Research Institute (MBARI) was downloaded as an ASCIIRaster file from http://www3.mbari.org/data/mapping/NorCal_Oregon_Margin/eel_river.htm (EelriverA.asc.gz). The bathymetry data were imported into ArcMap and projected from geographic coordinates to UTM, zone 10, WGS84 coordinates. The UTM grid was reprojected to UTM, zone 10, NAD83 coordinates and resampled to 30-m resolution.

In 2018 and 2019 the NOAA ships Rainier and Fairweather mapped five regions along the southern Cascadia Margin (NOAA survey IDs H13117, H13118, H13206, W00474, and W00475) using Kongsberg EM-710 multibeam echosounders. These bathymetry surfaces are available from NOAA, National Centers for Environmental Information and were downloaded from https://ngdc.noaa.gov/mgg/bathymetry/multibeam.html as BAG files. The BAG files were imported into Caris HIPS and SIPS, version 11 and converted to LAS files. The files were imported into ArcMap, version 10.8.1 and converted to grids.
