Description:
Abstract:
Marine geophysical mapping of the Queen Charlotte Fault in the eastern Gulf of Alaska was conducted in 2016 as part of a collaborative effort between the U.S. Geological Survey and the Alaska Department of Fish and Game to understand the morphology and subsurface geology of the entire Queen Charlotte system. The Queen Charlotte fault is the offshore portion of the Queen Charlotte-Fairweather Fault: a major structural feature that extends more than 1,200 kilometers from the Fairweather Range of southern Alaska to northern Vancouver Island, Canada. The data published in this data release were collected along the Queen Charlotte Fault between Cross Sound and Noyes Canyon, offshore southeastern Alaska from May 18 to June 11, 2016. Data were collected aboard the Alaska Department of Fish and Game research vessel Medeia using a Reson SeaBat 7160 multibeam echosounder. This data release contains approximately 453 square kilometers of multibeam bathymetric and backscatter data gridded at 10-meter resolution. Multibeam water column imagery and seismic profile data also collected during this survey are not published in this data release
Purpose:
The purpose of this polyline shapefile is to provide a geospatial record of the raw Reson 7160 filenames used to create the bathymetry and backscatter mosaics.
Supplemental_Information:
The R/V Medeia owned and operated by the Alaska Department of Fish and Game (AKDFG) was mobilized in her homeport of Juneau, AK May 12-15, 2016. Once mobilized the vessel transited to the northern section of the survey area in Cross Sound via the Icy Strait. The survey area covered 453 square kilometers from Cross Sound in the north, to Noyes Canyon in the south and was subdivided into 6 general "Blocks" to facilitate data processing and management. Each Block was 60-75 kms long and approximately 10-12 kms wide.

Sonar Configuration: Bathymetry data were collected using a Reson SeaBat 7160 multibeam echosounder operating at a frequency of 44 kHz. The sonar transducer was mounted from the starboard side of the R/V Medeia about 2 meters below the waterline. Vessel attitude was recorded using an Applanix POS MV 320 V5 to provide attitude and positioning that was mounted on the centerline of the vessel. Data were collected using the Reson 7k Control Center and HYPACK (v. 2016). Speed of sound was recorded at 5-8 hour intervals using a Oceanscience RapidCAST SV system mounted on the starboard quarter. Navigation was recorded using Differential Global Positioning System and a Hemisphere MBX-4 GPS receivers mounted above the bridge.

Process_Description:
STEP 1: DATA ACQUISITION multibeam bathymetry data were collected along the Queen Charlotte fault in southeast Alaska using a Reson SeaBat 7160 multibeam sonar operating at a frequency of 44 kHz that was mounted on wing-mount from the starboard side of the R/V Medeia owned and operated by the Alaska Department of Fish and Game. The sonar collected depth, backscatter (time series), and water column data along approximately 4178 kilometers of survey lines oriented parallel with the gradient of the continental shelf west of Chichagof and Baranof islands in southeast Alaska. Data were collected using the Reson 7k Control Center and HYPACK (v. 2016).
TerraSond LLC of Seattle Washington was responsible for leasing, mobilizing and operating all equipment related to the Reson 7160. Doug MacGillivray and David Maggio of TerraSond were in charge of all multibeam data acquisition. The contact person for this and all subsequent processing steps below is Brian Andrews.

STEP 2: IMPORT RAW BATHYMETRY FILES TO CARIS HIPS.
Multibeam bathymetry processing within CARIS HIPS (v. 9.1.1) during the survey consisted of the following flow:
1) Vessel configuration file was created in CARIS (RVMedeia.hvf) which includes, linear and angular installation offsets and vendor specified uncertainty values for each of the survey sensors.
2) A CARIS HIPS project (v. 9.1.1) was created with projection information set to Universal Transverse Mercator (UTM) Zone 8N, WGS 84.
3) Each survey line was recorded to both a Reson .s7k, and a Hypack (v. 2016) .HSX, .RAW, and .7k files. The Hypack .HSX files were imported to the new CARIS project using the Import/Conversion Wizard.
4) Delayed heave data from raw POS MV files were used to update HIPS survey lines using the import auxiliary data function.
5) Navigation was reviewed and edited as needed using the Navigation Editor tool.
6) Sound velocity correction was applied using the CARIS algorithm, a master SVP file containing all the sound velocity profiles collected during the survey and specifying the nearest in distance method, delayed heave source, and use surface sound speed.
7) Data were merged selecting "no tide" and the delayed heave source.
8) Total Propagated Uncertainty (TPU) was calculated for each line file using the manufacturer's offset values in the vessel configuration file.
9) A 10-m resolution depth surface was created using the Combined Uncertainty Bathymetric Estimator (CUBE) method for each of the six blocks. Surfaces were reviewed for inconsistencies and anomalies. The swath and subset editors were used to remove spurious points through manual editing and filter application, and the refraction editor was used to adjust sound speed values in areas where velocimeter data did not adequately correct depth profiles, which were obviously influenced by local anomalies in speed of sound through the water column.
10) Survey lines adjusted for refraction anomalies were remerged, and the respective CUBE surfaces were recomputed to reflect the changes. Processing during the survey was primarily focused on QA/QC during acquisition. Editing processes required trial and error, and were at times iterative.

Process_Description:
STEP 3: APPLY POST PROCESSED SBET FILES AND EDIT SOUNDINGS.
Vessel attitude data were processed using PosPac (v. 7.2) after the final ephemeris data were available 2 weeks after completion of the survey.
1) Post-processed navigation, vessel attitude, and GPS height data from POSPac SBET files, and post-processed RMS attitude error data from POSPac smrmsg files were used to update HIPS survey lines using the import auxiliary data function.
2) Navigation source was set to Applanix SBET, and navigation was reviewed and edited as needed using the Navigation Editor tool.
3) GPS tide was computed using the post-processed delayed heave data, the vessel water line, and a single datum value of 0 m (vertically referencing the data to the WGS 84 Ellipsoid)
4) Sound velocity correction was reapplied using the CARIS algorithm, the master SVP file containing all the sound velocity profiles collected during the survey and specifying the nearest in time method, delayed heave source, and use surface sound speed.
5) Data were remerged selecting the GPS tide and delayed heave sources.
6) New CUBE surfaces were created for each of the 6 survey blocks and interpolated to fill small "no data" gaps.

STEP 4: EXTRACT NAVIGATION FROM HIPS TO SHAPEFILE
The HIPS line files were exported to an Esri shapefile using the steps below. 1) Export lines to a Hydrographic Object Binary (HOB) file using the export HIPS and SIPS Data option from the file menu.
2) Using the context menu, export the hob file to a shapefile using the UTM Zone 8, WGS 84 coordinate system.
