Other PIs included on the project were Bill Boicourt (University of Maryland), David Jay (University of Washington), and Len Pietrafesa (North Carolina State University). Twenty-two current meter arrays (14 surface and 8 subsurface moorings) were deployed in the vicinity of the mouth of the Columbia River from Oct. 1990 through Feb. 1991. Most sites were paired with a surface mooring and a subsurface mooring located within the same vicinity. Positions for the sites and their mooring ID are shown on the CRmoorsitesfla50.jpg file included with the data. In most cases surface and subsurface moorings for the same location were deployed within a quarter mile of each other and are represented as one station on the chart. If the distance between the surface and subsurface moorings was greater than a quarter of a mile an average position was used to plot that station. Surface moorings are designated by the mooring ID followed by an 'S' to indicate surface while the subsurface moorings have an 'A' appended to the mooring ID. Contour lines for 25, 50, 100, 250, 500 meters are shown. Results from this study can be found in Hickey, B.M., L. Pietrafesa, D. Jay and W.C. Boicourt (1998) The Columbia River Plume Study: Subtidal variability of the velocity and salinity fields. Journal of Geophysical Research, 103(C5): 10339-10368. The purpose of this project was to determine the dynamics of the formation of the Columbia River plume and the role of mixing processes in plume formation.

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 water level recorder water level recorder A seabed mounted unit calculating water level by means of precise measurements of hydrostatic pressure. moorings entry created as MOORINGS OF UNITED STATES, but has been used as a generic MOORINGS entry.
