        abstract:  This dataset includes navigational, physical and underway data collected aboard the ATLANTIS during cruise AT26-19 in the Columbia River estuary - Washington/Oregon and North Pacific Ocean from 2014-08-28 to 2014-09-11. These data include CURRENT SPEED - EAST/WEST COMPONENT (U), CURRENT SPEED - NORTH/SOUTH COMPONENT (V), LATITUDE, LONGITUDE, course over ground and speed over ground. The instruments used to collect these data include ADCP and GPS. These data were collected by Charles Langmuir of Harvard University, and by Woods Hole Oceanographic Institution as part of Sea-going Experiments to Test Potential Linkages among Sea Level Change, Ocean Ridge Volcanism, and Hydrothermal Activity (SeaVOICE). 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. 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.

        supplementalInformation:  NCEI Accession 0086548 contains documentation about data sets submitted to NCEI as part of the Rolling Deck to Repository program. One or more of the data packages in this dataset contain an incorrect data license. The R2R team has requested that all such packages must be documented with a Creative Commons CC0 1.0 Universal (CC0 1.0) Public Domain Dedication. The documentation has been updated accordingly. However, none of the original data files have been changed. In this accession, NCEI has archived multiple versions of these data. The latest (and best) version of these data has the largest version number.

            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.
