University of Washington author Barbara M. Hickey University of Washington (UW) pointOfContact University of Washington (UW) contributor tableDigital The Ecology and Oceanography of Harmful Algal Bloom-Pacific North West (ECOHAB PNW) was a 5-year multi-disciplinary project that studied the physiology, toxicology, ecology and oceanography of toxic Pseudo-nitzschia species off the Pacific Northwest coast. As part of this project Dr. Barbara Hickey at the University of Washington maintained 3 surface moorings and one subsurface mooring in the vicinity of the Juan de Fuca Eddy. The three surface moorings, E1, E2, E3, were deployed during the spring through early fall season in 2003-2006. One subsurface mooring, E4, was maintained 2005-2008. It was deployed between late June and August and recovered in October, except for the 2007 deployment which was not recovered until January 2008. Dr. Rick Thomson at the Institute of Ocean Sciences and his group designed the moorings with scientific input from Dr. Hickey. One of the many components of this project was to design and maintain three surface moorings and one subsurface mooring to collect time series data of water properties and currents in the Juan de Fuca eddy region during the general time period of May through September or early October, 2003-2006. The project was funded jointly through the Ecology and Oceanography of Harmful Algal Blooms program by the National Oceanographic and Atmospheric Administration Coastal Ocean Program Award Number NA17OP2789 and the National Science Foundation (NSF) Award OCE 0234587. Lead Principal Investigators were Dr. Barbara Hickey, University of Washington, and Dr. Vera Trainer, Northwest Fisheries Science Center. Mooring recovery and deployment on the Canadian Coast Guard Offshore Research and Survey Vessel John P. Tully was made possible by Canadian support to Dr. Rick Thomson at the Institute of Ocean Sciences. Additional funding was provided by NSF (Awards OCE 0434087, OCE 0910624) and the National Institute for Environmental Health Sciences (P50 ES012762) through the Pacific Northwest Center for Human Health and Ocean Studies to continue the E4 mooring through 2008.

On the subsurface mooring, E4, the ADCP was upward facing and was set up to average 150 pings evenly sampled over 30 minutes.

All data was rotated to true North.; Data Quality Information: ADCPs measure water velocity at several depths, referred to as bins. Data was sampled in earth coordinates. Data was checked for u and v values of 9999s, indicating bad data. Values were linearly interpolated across the bad data. The ADCP collects ancillary data that was used to evaluate the data. If the percent good 4 beam solutions was <25, correlation magnitude was <64, or tilt was >15 degrees then the data was filled with a regression on the bin above it if the ADCP was downward facing. If the ADCP was upward facing, data would be filled with a regression on the bin below.

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.
