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. bathythermograph - XBT bathythermograph - XBT eXpendable BathyThermograph CTD CTD Conductivity-Temperature-Depth probe echo sounder echo sounder instrument used to determine water depth or bathymetry also known as an echosounder fluorometer fluorometer fluorometer GPS GPS Global Positioning System receiver satellite-based instrument used for geo-location, positioning and navigation humidity sensor humidity sensor HUMIDITY SENSORS are devices that receive a signal or stimulus (as heat or pressure or light or motion etc.) and responds to it, in this case humidity or some measure of the water vapor content of air. oxygen sensor oxygen sensor Any instrument that measures oxygen content in a compound. pressure sensor pressure sensor GCMD instruments - In Situ/Laboratory Instruments > Pressure/Height Meters > PRESSURE SENSORS ASFA Thesaurus - pressure sensors http://www4.fao.org/asfa/asfa.htm salinometer salinometer generic salinometer use salinometer when the instrument type used is unclear but the data include salinity measurements sound velocimeter sound velocimeter an electronic device for measuring sound speed in water http://www.neigps.com temperature sensor temperature sensor A sensor used to measure temperature. turbidity sensor turbidity sensor Measures the turbidity of water Turbidity sensors measure the amount of light that is scattered by suspended solids in a liquid, such as water. When the concentration of total suspended solids (TSS) and total dissolved solids (TDS) in a liquid increase, the turbidity also increases.
