        abstract:  NCEI Accession 0162336 includes biological, navigational and other data collected aboard the ATLANTIS during cruise AT25 in the North Atlantic Ocean from 2013-05-03 to 2013-05-06. These data include CONDUCTIVITY, CURRENT SPEED - EAST/WEST COMPONENT (U), CURRENT SPEED - NORTH/SOUTH COMPONENT (V), DEPTH - BOTTOM, DEPTH - OBSERVATION, FLUORESCENCE, HYDROSTATIC PRESSURE, LATITUDE, LONGITUDE, SALINITY, WATER TEMPERATURE, course over ground, speed over ground and surface irradiance. The instruments used to collect these data include ADCP, CTD, GPS, PAR Sensor, echo sounder and fluorometer. These data were collected by Woods Hole Oceanographic Institution as part of Hydro Winch Testing. The Lamont-Doherty Earth Observatory (LDEO) submitted these data to NCEI as part of the Rolling Deck to Repository (R2R) program. A suite of navigation products produced by the Rolling Deck to Repository program is included in this accession, which include one high resolution, one 1 minute resolution, and one low resolution coordinate file. R2R provides a processed version of the CTD data. The ADCP data represent the raw data set. Post processed quality assessed data are not available in this accession.
        purpose:  This dataset is available to the public for a wide variety of uses including scientific research and analysis.

            description:  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.

            description:  Photosynthetically Active Radiation Sensor The PAR sensor measures global solar radiation from 400 to 700 nm, which approximates the spectral band active in photosynthesis. The response of the instrument falls sharply to zero on either side of this band, and between 400 and 670 nm it increases monotonically from about 50% to 100%. There is no protective glass dome over the receiving surface. Irradiance from the sun passes through a small white visible bandpass filter/diffuser in the shape of a horizontal disk at the top of the instrument. Within the instrument radiation is directed through a series of colored glass filters and onto a silicon photodiode detector. The factory-supplied calibration converts the signal from the detector to a flux of photons in micro-mole (of photons) s-1 m-2. (One micro-mole equals 6.022 E17 photons.) For the solar spectrum, these units may be converted to watts per square meter by dividing by 4.6. (http://www.srrb.noaa.gov/instrument/par.htm)
