<div><p>A Teledyne RDI 600 kHz Work Horse Acoustic Doppler Current Profiler (RDI ADCP) was mounted looking upward on a bottom frame at nominal depth of 30m. Sampling was set for every 300 seconds (5min). Depth resolution was set to 1 meter. </p>
<p>LB2 ADCP did not have a pressure sensor and LB3 ADCP pressure sensor malfunctioned. Pressure records from the collocated bottom-frame CTDs were used to form the surface mask in ADCP profile data</p></div>
ADCP data from Long Bay Mooring #2, 76 meters, Jan - April 2012
LB_2012_LB2_ADCP_76m
<div><p>Data were read from ADCP binary format using Rich Pawlowicz’s MATLAB functions to read binary and processed RDI ADCP files. [1]</p>
<p>Quality control (QC) steps applied are based on Teledyne RDI recommendations [2] and QARTOD guidance [3]. Quality controlled ADCP data were flagged with Not-a-Number (NaN) (changed to nd by BCO-DMO) under the following conditions:</p>
<p>1. when bottom frame not at deployment depth (trimming beginning and end values)<br />
2. sensor health parameters (pitch, roll, heading, water temperature) not within tolerances<br />
3. quality and strength of returned signal not sufficient based on the following parameters:<br />
a. Echo Intensity<br />
b. Correlation Magnitude<br />
c. Error Velocity <br />
d. Percent Good <br />
4. surface masking based on beam angle and addition roll and/or pitch and surface location from water level determined from pressure sensor on ADCP or collocated on the bottom frame.</p>
<p>The ADCP configuration info and tolerances used in the QC processing for each ADCP (LB1, LB2, and LB3) are provided with each dataset.</p>
<p>As a final step, the horizontal velocity components were rotated to be relative to True North based on magnetic variation of the deployment location after verifying no internal application of magnetic variation was applied to data.</p>

BCO-DMO Processing:
-extracted data from MatLab .mat file
-added conventional header with dataset name, PI name, version date, reference information
-renamed parameters to BCO-DMO standard
-added deployment_id, lat, lon
-added 'day_local', 'month_local', 'year', 'yrday_local', ISO_DateTime_UTC to served view
-changed NaN to nd
-reduced number of significant digits
ADCP data from the South Atlantic Bight (SAB) continental shelf off Long Bay (Mooring #2) at 76 meters collected from January to April in 2012 (Long Bay Wintertime Bloom project)
Time series of horizontal and vertical current profiles measured every 5 minutes (300sec) with an acoustic doppler current profiler (ADCP) mounted on the bottom frame looking upward. The depth resolution is 1 meter. The mooring is located at Long Bay, S. Carolina in the South Atlantic Bight and recorded from 76 meters depth.
