Edition: version 1 Geospatial_Data_Presentation_Form: raster digital data Online_Linkage: \\Mlkapp\fram\OlympicCoast\hmpr-110-2002-04\Catalog\Bathy\dtm110a Description: Abstract: In 2002 and 2003, hydrographic survey data were collected using Reson 8101 multibeam echosounders outfit to 9.8m survey launches. Bathymetry data were cleaned of anomalies using Caris HIPS software, creating BASE (Bathymetry Associated with Statistical Error) surfaces for each of three survey blocks with the CUBE (Combined Uncertainty Bathymetric Estimator) method (Calder and Mayer 2003). Accepted XYZ values from the CUBE surface were ultimately converted to ESRI Arc ascii grid format. Purpose: The data represent seafloor topography at 1 meter resolution for an area roughly spanning James Island to Sand Point, Washington, with depths ranging from approximately -0.5m to -35m. Information from the surveys can be used to update nautical chart 18480 and provide detailed information on seabed characteristics for essential fish habitat (EFH) modeling.

In 2003, data were collected by Olympic Coast National Marine Sanctuary (OCNMS) staff using a NOAA Ship Rainier survey launch. All data processing was accomplished by Steven S. Intelmann OCNMS office in Port Angeles, WA. Security_Information: Security_Classification: Unclassified Native_Data_Set_Environment: Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 4; ESRI ArcCatalog 9.2.2.1350 Data_Quality_Information: Logical_Consistency_Report: Not Tested Completeness_Report: Unknown Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The 2003 survey data were intended to meet NOAA NOS hydrographic specifications, which can be found at http://chartmaker.ncd.noaa.gov/hsd/specs/specs.htm. NOS specification for hydrographic positioning is that the total error in position of soundings, dangers, and all other significant features, at the 95 percent confidence level, will not exceed 5 meters +5 percent of the depth. This accuracy requirement is independent of survey scale. The 2002 survey data may not meet these specifications. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: See NOS hydrographic stanards http://chartmaker.ncd.noaa.gov/hsd/specs/CHAPTER5.htm. The 2002 survey data may not meet NOAA NOS hydrographic standards due to sound velocity errors and/or timing or latency problems which were evident in the processed data. Lineage: Source_Information: Type_of_Source_Media: computer program Process_Step: Process_Description: Hydrographic data were collected using Reson 8101 multibeam echosounders by either the R/V MacGinitie (2002) or the NOAAS Rainier survey launch RA3 (2003). In both years, Coastal Oceanographics Hypack was used for line control and planning and Isis Sonar was used to log sonar information. Data were logged in XTF format. Process_Date: Time of acquisition Process_Step: Process_Description: Sound velocity data were collected using a Seabird SVP 19 plus profilers. SVP and Tide merging were accomplished in Caris Hips.
