A raw and a processed version are given in each dataset, both of which include ancillary data streams from CTD, ship navigation, and shipboard ADCP. The data were collected on R/V R.Revelle for cruise TN390 on World Ocean Circulation Experiment lines A22 from 2022-06-13 to 2022-07-16. This cruise is part of the NCEI collection for GO-SHIP LADCP. The finalized datasets have been assembled and submitted to NCEI by the LADCP data management staff of University of Hawaii and the Lamont-Doherty Earth Observatory. The originators of each LADCP set are defined within the accession documentation. Data files for the processed set are in ASCII text, PDF, and NetCDF. Raw data are given in proprietary binary files and made available in case a user prefers to reprocess the set from \u201clevel-0\u201d status.\r\n \r\n \r\n To understand the ocean currents through the water column.\r\n \r\n \r\n Funding Agency: National Science Foundation (NSF)\r\n \r\n \r\n completed\r\n \r\n \r\n historicalArchive\r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n \r\n \r\n \r\n \r\n ncei.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/contact\r\n \r\n \r\n HTTPS\r\n \r\n \r\n NCEI Contact Information\r\n \r\n \r\n Information for contacts at NCEI.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n asNeeded\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0289388\r\n \r\n \r\n Preview graphic\r\n \r\n \r\n PNG\r\n \r\n \r\n \r\n \r\n \r\n \r\n 0289388\r\n \r\n \r\n \r\n \r\n NCEI ACCESSION NUMBER\r\n \r\n \r\n \r\n \r\n 2024-02-05\r\n \r\n \r\n publication\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n CONDUCTIVITY\r\n \r\n \r\n CURRENT SPEED - EAST/WEST COMPONENT (U)\r\n \r\n \r\n CURRENT SPEED - NORTH/SOUTH COMPONENT (V)\r\n \r\n \r\n CURRENT SPEED - UP/DOWN COMPONENT (W)\r\n \r\n \r\n HYDROSTATIC PRESSURE\r\n \r\n \r\n OXYGEN\r\n \r\n \r\n SALINITY\r\n \r\n \r\n WATER TEMPERATURE\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n NODC DATA TYPES THESAURUS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n ADCP\r\n \r\n \r\n CTD\r\n \r\n \r\n pressure sensor\r\n \r\n \r\n instrument\r\n \r\n \r\n \r\n \r\n NODC INSTRUMENT TYPES THESAURUS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n derived products\r\n \r\n \r\n in situ\r\n \r\n \r\n physical\r\n \r\n \r\n profile\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n NODC OBSERVATION TYPES THESAURUS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n R/V Roger Revelle\r\n \r\n \r\n platform\r\n \r\n \r\n \r\n \r\n NODC PLATFORM NAMES THESAURUS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Lamont-Doherty Earth Observatory\r\n \r\n \r\n The University of Hawai'i System\r\n \r\n \r\n dataCentre\r\n \r\n \r\n \r\n \r\n NODC COLLECTING INSTITUTION NAMES THESAURUS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n The University of Hawai'i System\r\n \r\n \r\n dataCentre\r\n \r\n \r\n \r\n \r\n NODC SUBMITTING INSTITUTION NAMES THESAURUS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Joint Archive for Shipboard ADCP (JASADCP)\r\n \r\n \r\n The Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP)\r\n \r\n \r\n project\r\n \r\n \r\n \r\n \r\n NODC PROJECT NAMES THESAURUS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n North Pacific Ocean\r\n \r\n \r\n place\r\n \r\n \r\n \r\n \r\n NODC SEA AREA NAMES THESAURUS\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n oceanography\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n WMO_CategoryCode\r\n \r\n \r\n \r\n \r\n 2012-09-15\r\n \r\n \r\n publication\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n COLUMBIA/LDEO > Lamont-Doherty Earth Observatory, Columbia University\r\n \r\n \r\n dataCentre\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Data Center Keywords\r\n \r\n \r\n \r\n \r\n 2025\r\n \r\n \r\n revision\r\n \r\n \r\n \r\n \r\n 21\r\n \r\n \r\n \r\n \r\n Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA)\r\n \r\n \r\n \r\n \r\n \r\n \r\n Greenbelt\r\n \r\n \r\n MD\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords\r\n \r\n \r\n HTTPS\r\n \r\n \r\n GCMD Keyword Forum Page\r\n \r\n \r\n Global Change Master Directory (GCMD). 2025.

ADCPs typically have 4 beams, allowing measurement of velocity in 3 dimensions, in bins of varying distance from the transducer head. In this application, the ADCP is mounted on a CTD rosette frame and lowered along with the rest of the package, hence called Lowered ADCP (\"LADCP\"). The goal is to determine water velocities to the full depth of the ocean for each deployment. Ocean velocities are very small (few cm/s), especially in the deep water. The package is typically lowered or raised at 1m/s for much of the water column, creating a challenging data processing situation. Lowered ADCP data requires ancillary information to improve the processed data product. Over generations, the processing has improved and these ancillary components are systematically collected along with the LADCP data. These ancillary measurements include Conductivity, Temperature, and Depth, at 24Hz, with 1Hz position, and shipboard ADCP data.;\r\nData Quality Method: Two levels of data are provided: 1. raw-level0 directory: The raw data can be considered to be \"level 0\", i.e. original data from an instrument. The goal of the level-0 data is that someone would be able to take modern processing techniques and apply them to older datasets. 2. processed-level1: The processed data can be considered to be \"level 1\", i.e. algorithms combining data from ancillary measurements along with the LADCP data, transformations and editing, and other algorithms are applied along with some quality control, to create a profile of ocean velocity. These data products are the \"state of the art at the time\"; they have not been reprocessed with modern methods.

The goal is to determine water velocities to the full depth of the ocean for each deployment. Ocean velocities are very small (few cm/s), especially in the deep water. The package is typically lowered or raised at 1m/s for much of the water column, creating a challenging data processing situation. Lowered ADCP data requires ancillary information to improve the processed data product.

Sound signals sent from the moving ship bounce back to receivers aboard the ship. This provides a profile of water movement relative to the ship-precise modern navigation, allowing the ship's motion to be subtracted from the data. These devices are also used on moorings and profilers and, along with acoustic backscattering, measure animal biomass. Particles in the path of the sound waves, mostly plankton, reflect a small part of the sound energy back toward receivers, allowing researchers to make remote estimates of the sizes and numbers of animals present in the water column. Before the 1970's, the most technologically advanced instrument used to measure water velocity was known as a Doppler speed log. This evolved into the first commercial ADCP, produced in the mid-1970's, which used averaging. Later in the 1970's, the first vessel-mounted ADCP was developed to measure water velocity more accurately and to allow measurement in range cells over a depth profile.\r\n\r\nAs instruments evolved, so did new techniques in Doppler signal processing. Initially, Doppler speed logs used simple analog signal processing methods, which are still used in some commercial speed logs today. However, the first ADCPs incorporated analog-to-digital signal conversion over a narrow communication bandwidth. Around 1990, this technique was developed into broadband signal processing. Since then, broadband ADCPs have been able to generate very accurate, real-time velocity measurements.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n CTD\r\n \r\n \r\n \r\n \r\n CTD\r\n \r\n \r\n Conductivity-Temperature-Depth probe\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n pressure sensor\r\n \r\n \r\n \r\n \r\n pressure sensor\r\n \r\n \r\n GCMD instruments - In Situ/Laboratory Instruments > Pressure/Height Meters > PRESSURE SENSORS\r\n\r\nASFA Thesaurus - pressure sensors\r\nhttp://www4.fao.org/asfa/asfa.htm\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n R/V Roger Revelle\r\n \r\n \r\n \r\n \r\n Flag: United States\r\nType: Research Vessel\r\nIMO: 9075228\r\nCompany: Scripps Institution of Oceanography\r\nDOB: 1996-06\r\n\r\nhttps://scripps.ucsd.edu/ships/revelle\r\n \r\n \r\n \r\n \r\n \r\n \r\n","source_transform":null,"status":"error"}
