Description:
Abstract:
This portion of the USGS data release presents gridded bathymetry data derived from repeated bathymetric surveys conducted by the U.S. Army Corps of Engineers Portland District on the Pacific Ocean, Washington. Repeated surveys were performed between September 9, 2020, and March 10, 2021, from a vessel equipped with a multi-beam bathymetry system to characterize the morphology and dispersal of a nearshore berm composed of sediment dredged from the navigational channel at the mouth of the Columbia River. Digital data files containing gridded bathymetry data for each survey are provided in ESRI ARC ASCII (*.asc) format. These data accompany Stevens and others (2023).
Purpose:
Bathymetry data were obtained to characterize the morphology and dispersal of a nearshore berm composed of 216,000 cubic meters of sediment dredged from the navigational channel at the mouth of the Columbia River and placed outside the inlet in water depths between 12 and 15 m.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: No formal attribute accuracy tests were conducted.
Logical_Consistency_Report: No formal logical accuracy tests were conducted.
Completeness_Report:
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:
The Applanix POS-MV post-processed horizontal positional accuracy is about 0.1 m with roll and pitch accuracies of about 0.02 degrees (https://www.applanix.com/downloads/products/specs/posmv/POS-MV-WaveMaster-II.pdf). The SeaBat T50-P multibeam sonar system has an across-track beam width of 1 deg (http://www.teledynemarine.com/Lists/Downloads/RESON/SeaBat/SeaBat%20T50-P%20product%20leaflet.pdf) resulting in a resolution of about 17 cm in a water depth of 10 m. Accuracies of final products may be lower due to 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:
The Applanix POS-MV post-processed vertical positional accuracy is about 0.2 m (https://www.applanix.com/downloads/products/specs/posmv/POS-MV-WaveMaster-II.pdf). The SeaBat T50-P multibeam sonar system has a measurement resolution limit of 0.6 cm (http://www.teledynemarine.com/Lists/Downloads/RESON/SeaBat/SeaBat%20T50-P%20product%20leaflet.pdf). Accuracies of final products may be lower due to total propagated uncertainties of the mapping systems, which include sonar system, position and motion compensation system, fluctuations in the speed of sound in seawater, as well as data processing that includes sounding cleaning, gridding, and datum transformations.

Process_Step:
Process_Description:
Previously unpublished bathymetric data were acquired by the U.S. Army Corps of Engineers, and released here with the permission of the USACE. Bathymetric surveys were performed using the survey vessel Elton equipped with a Reson SeaBat T50-P mulitbeam sonar operated at 400 kHz. Depths were computed with sound velocity measurements acquired with either a YSI CastAway CTD or AML X2 Series sound velocity profiler. Positioning was achieved with an Applanix POS-MV Wavemaster II and submersible IMU operating primarily in real-time kinematic mode with differential corrections transmitted via NTRIP from the Oregon Real Time GNSS Network (https://www.oregon.gov/odot/ORGN/Pages/index.aspx). Post-processed positions were applied using Applanix POSPac MMS software when real time communications between the survey vessel and geodetic network failed. Hypack hydrographic software was used for survey data acquisition and post processing. Elevations relative to mean lower low water (MLLW) were computed using offsets from the National Geodetic Survey Geoid12a geoid model and tidal datum established at Hammond, Oregon.

Process_Step:
Process_Description:
Original data were re-projected using UTM Zone 10, meters coordinate system and elevations were converted from survey feet to meters. Processed bathymetry data from each survey were gridded onto a using bin averaging onto a regular grid with 5-m resolution.
