Raw ADCP (Acoustic Doppler Current Profiler) datasets from acoustic interference surveys with a TRDI Workhorse 300, a Nortek Signature500 and two Signature1000 instruments from August 2020. One Signature 1000 ADCP was deployed for 13 days on a bottom lander in Sequim Bay Inlet, WA. Data from the other three instruments were taken from a survey vessel running transects above the deployed lander.

Acoustic Doppler Current Profiler (ADCP) data from seafloor tripods in Admiralty Inlet, Puget Sound, Washington. Data collected from April 2009 through December 2012. When using the data, please cite the J. Oceanic Eng. paper included in this submission, and please contact Jim Thomson prior to submitting publications or conference abstracts that use the data.

Tripod and mooring data using acoustic doppler velocimeter (ADV) and acoustic doppler current profiler (ADCP) of tidal turbulence. When using the data, please cite the J. Oceanic Eng. paper included in this submission, and please contact Jim Thomson prior to submitting publications or conference abstracts that use the data.

This data is from measurements at Admiralty Head, in Admiralty Inlet. The measurements were made using an IMU equipped ADV mounted on a mooring, the 'Tidal Turbulence Mooring' or 'TTM'. The inertial measurements from the IMU allows for removal of mooring motion in post processing. The mooring motion has been removed from the stream-wise and vertical velocity signals (u, w). The lateral (v) velocity may have some 'persistent motion contamination' due to mooring sway. The ADV was positioned 11m above the seafloor in 58m of water at 48.1515N, 122.6858W. Units ------ - Velocity data (_u, urot, uacc) is in m/s. - Acceleration (Accel) data is in m/s^2. - Angular rate (AngRt) data is in rad/s. - The components of all vectors are in 'ENU' orientation. That is, the first index is True East, the second is True North, and the third is Up (vertical). - All other quantities are in the units defined in the Nortek Manual. Motion correction and rotation into the ENU earth reference frame was performed using the Python-based open source DOLfYN library (linked in resources). Details on motion correction can be found there. For additional details on this dataset see the included Marine Energy Technology Symposium paper.

Current meter data from the ADCP instruments of BE/335 and BW/333 from January 3, 1991 to November 26, 1992 collected as part of the World Ocean Circulation Experiment (WOCE).

A bottom moored echosounder was deployed at 116.3 m depth in the NW Bering Sea (61.36881 N, 177.17 W) from 26 July 2019 to 31 August 2020. The mooring was instrumented with a battery powered EK80 wideband autonomous transceiver (WBAT, Simrad AS). The echosounder operated an upwards facing depth-rated 70 kHz 18° split-beam transducer (ES70-18CD), positioned upward with a two-axis gimbal equipped with a 0.7 kg counterweight. During the deployment, the WBAT was programmed to transmit an ensemble of 320 narrowband and 35 wideband every two hours. Data were recorded to a range of 155 m. Calibrations had occured in Seattle, Washington either prior to deployment or after recovery using a 38.1-mm tungsten carbide sphere following the standard sphere method (Demer et al., 2015).

This dataset contains water velocity data derived from spatial surveys performed with a vessel-mounted acoustic Doppler current profiler at four sites (SKM, SLG, LDB, WLW) in the lower Columbia River, Washington and Oregon, in 2021. The data are provided in netCDF (.nc) format and compressed into .zip archives for each site.

This dataset records results from a bottom-deployed upward-looking Acoustic Doppler Current Profiler (ADCP, 600 kHz Workhorse Monitor, Teledyne RD Instruments, Poway, California) deployed during the summer of 2019 (late June until early August) near Hammond Bay, Lake Huron (45.5948 degrees north, -84.1542 degrees east). Data were collected in support of nearby Cladophora and benthic algal assessments, as well as to validate hydrodynamic modeling.
