20873 NMFS Water Column Sonar Database Data Set Published / External 20872 NMFS Water Column Sonar Database Project In Work Unknown Water column sonar data are an important component of fishery independent surveys, habitat studies and other research. NMFS water column sonar data are archived here. Provide a searchable inventory of NMFS water column sonar data archived at the National Centers for Environmental Information. Theme multi beam sonar Theme split beam sonar Theme water column backscatter Temporal 1990 to present Spatial global ocean coverage Sent directly to archiving location. Data Set Files Continually Table (digital) Water column sonar data are collected by active acoustic (or sonar) technology and contain acoustic scattering information from the near-surface to the seafloor. Scientists use these data to assess physical and biological characteristics of the ocean, including the spatial distribution of plankton, fish, methane seeps, and underwater oil plumes. http://maps.ngdc.noaa.gov/viewers/water_column_sonar/ https://maps.ngdc.noaa.gov/viewers/water_column_sonar/ Cruises have specific citations that should be used when incorporating these data into your research, etc. Please see the ReadMe file provided during download or the "Cruise Details" for detailed information.

The configuration of each cruise's sonar system (e.g., beam type and angle) can be found in the file metadata. Data includes links to sonar calibration files, sound velocity profiles and CTD data. Yes Unknown Yes No No 90 Days NCEI-CO 90 Days Prior to submission, data are packaged using a data packager script, which combines metadata and data files with appropriate QC checks. 1 The data provider uses the WCSD Packager to create a Data Package from the Instrument Files and/or user entered cruise and instrument details. 2 The Data Package is sent to the WCSD Data Manager at NCEI in Colorado who ingests the data for archiving. 47538 Entity gov.noaa.nmfs.inport:20873 Jackie Locks 2013-11-08T17:56:05 SysAdmin InPortAdmin 2026-03-04T19:17:17 2015-12-22 NMFS Office of Science and Technology OST 1315 East West Highway Silver Spring MD 20910 USA 301-427-8100 https://www.st.nmfs.noaa.gov/ 0700 - 1800 EST/EDT 1001 Public No No 2015-12-22 1 Year 2016-12-22
