Abstract:
This part of SIM XXXX presents data for the bathymetry and shaded-relief maps (see sheet 1, SIM XXXX) of the Admiralty Inlet map area. The raster data file for the bathymetry map is included in "Bathymetry_AdmiraltyInlet.zip." The raster data file for the shaded-relief map is included in "BathymetryHS_AdmiraltyInlet.zip." Both are accessible from <https://pubs.usgs.gov/ds/781/AdmiraltyInlet/data_catalog_AdmiraltyInlet.html>. The bathymetry and shaded-relief maps of the Admiralty Inlet map area in the southern Salish Sea was generated from topography extracted from a Digital Elevation Model (DEM) by Finlayson (2005) and bathymetry data collected more recently by the National Oceanic and Atmospheric Administration (NOAA) (fig. 2-1). Surveys conducted in the Admiralty Inlet map area by the NOAA Ship Rainier include H11188 (NOAA, 2002), H11040 (NOAA, 2002b), H11039 (NOAA 2002c), H11038 (NOAA 2002d) and H11375 (NOAA 2005). Multibeam sonar data were acquired by the Ranier and its survey launches using Reson 8101, Reson 8125, and Elac 1180 multibeam systems.
Purpose:
These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to identify bathymetric features.

Process_Description:
The horizontal datum for Rainier surveys is the North American Datum of 1983 (NAD83). Differential GPS (DGPS) was the sole method of positioning. Differential corrections from U.S. Coast Guard beacons at Whidbey Island (transmitting on 302 kHz), and Robinson Point (transmitting on 323 kHz) were utilized during surveys. The vertical datum for the Rainier surveys is Mean Lower-Low Water (MLLW). The operating National Water Level Observation Network (NWLON) primary tide station at Port Townsend, AK (944-4900) served as control for datum determination and as the primary source for water level reducers. In addition to Rainier surveys, survey H11801 (NOAA 2009), was conducted using the Kvichak Defender IV for multibeam sonar and sound velocity data collection in waters deeper than 4 meters. Complete multibeam coverage was verified while in the field using a CARIS workstation aboard Kvichak Defender IV, with subsequent verifications performed shore-side on non-survey days. A CODA F-180 motion reference unit was mounted in a water-resistant case to the mid-ships port gunwale immediately adjacent to the Kongsberg EM3002 side-pole mount. The F-180 GPS antennae were mounted in an along-ship orientation with a 2 meter separation between primary and secondary antennae. The R/V Storm was used for gap-fill surveys on the 20-27th January 2009, 3-6 February 2009 and 17-18 February 2009. Storm was configured with a dual-head Reson 7125 MBES and tasked with acquisition of least depths on rocky shoals at the approach to Oak Harbor channel as well as performing gap-fills after conclusion of large boat operations by Kvichak Defender IV. R/V Storm employed Hypack for navigation and raw data acquisition, POS/MV was used for motion and heading and a Sea-Bird CTD for sound speed profiles. Once all the bathymetric-surface models were transformed to a common projection and datum, the files were merged into one overall 2-m-resolution bathymetric-surface model, merged with an onshore DEM from Finlayson (2005), and clipped to the boundary of the map area. Difference calculations of the overlapping bathymetry grids showed that there is good agreement between surveys, even though the surveys were conducted at different times.

Process_Description:
Merge all bathymetry data into 2-m-resolution bathymetry grid and clip to the Admiralty Inlet map boundary. To create the shaded-relief imagery, an illumination having an azimuth of 315 degrees and 45 degrees above the horizon was applied to the bathymetry grid.
