Each current meter netCDF file in the set represents a single instrument's complete record of east and north velocity components, as well as instrument depth, with respect to time. Each ADCP netCDF file contains a current profile time series for the same periods. The records have been edited to remove samples stored during the deployment and recovery periods, and have been corrected for magnetic declination and local sound velocity. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0156669 Preview graphic PNG 0156669 NCEI ACCESSION NUMBER 2016-08-29 publication CURRENT METER - NORTH-SOUTH COMPONENT (V) CURRENT SPEED - EAST/WEST COMPONENT (U) theme NODC DATA TYPES THESAURUS ADCP current meter instrument NODC INSTRUMENT TYPES THESAURUS in situ theme NODC OBSERVATION TYPES THESAURUS HMAS Melville moored buoys R/V Knorr platform NODC PLATFORM NAMES THESAURUS University of Miami dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS University of Miami dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Indian Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication EARTH SCIENCE > OCEANS > OCEAN CIRCULATION > OCEAN CURRENTS theme Global Change Master Directory (GCMD) Science Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

NOAA National Centers for Environmental Information custodian ADCP ADCP Acoustic Doppler Current Profiler The Acoustic Doppler Current Profiler (ADCP) measures currents beneath a ship while underway. 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. As 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. current meter current meter current meter HMAS Melville Additional information about this platform from ICES: Flag : AUSTRALIA - AU (ISO Country Code) Call Sign : VLSF Title : HMAS Platform Class : Naval vessel Pennant : A 246 Commissioned Date : 2000-05-27 Current Length : 71.2 Built : 2000 Notes : Hydrographic survey ship Additional Information Sources: - http://www.navy.gov.au/HMAS_Melville moored buoys created for MOORED BUOYS OF ITALY, but became used as a generic MOORED BUOY keyword. see platforms_id 13759.
