The entire cruise was carried out during the period from July to September, 2013. Hydrographic observation was made using a SeaBird Electronics (SBE) 36 position carousel equipped with 10-liter Niskin water sample bottles, a CTD system (SBE911plus) equipped with JFE Advantech oxygen sensor (RINKO III) along 179E. Water samples were analyzed for salinity, dissolved oxygen, nutrients, pH and phytopigment (chlorophyll-a and phaeopigments). Current data was measured by Teledyne RDI's vessel-mounted ADCP system (38kHz Ocean Surveyor). This dataset is U.S. State Department MSR U2013-006 as part of the World Data Service for Oceanography. Data are in PDF. 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:0220629 Preview graphic PNG 0220629 NCEI ACCESSION NUMBER 2020-09-08 publication CHLOROPHYLL - RELATIVE FLUORESCENCE CURRENT DIRECTION CURRENT SPEED DISSOLVED OXYGEN NITROGEN pH PHAEOPIGMENTS phosphate SALINITY silicate theme NODC DATA TYPES THESAURUS ADCP CTD Niskin bottle instrument NODC INSTRUMENT TYPES THESAURUS biological chemical derived products in situ physical profile theme NODC OBSERVATION TYPES THESAURUS Ryofu Maru platform NODC PLATFORM NAMES THESAURUS Japan Meteorological Agency dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS Japan Meteorological Agency dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS U.

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.
