Current velocity data from a continuous survey using a towed ADCP in Altamaha Sound, Georgia, USA

<p><strong>Title:&nbsp; </strong>Current velocity data from a continuous survey using a towed ADCP in Altamaha Sound, Georgia, USA</p> <p><strong>Author/Data Collector: </strong>Chunyan Li</p> <p><strong>Point of Contact, PI, Originator:&nbsp; </strong>Chunyan Li (cli@lsu.edu)</p> <p><strong>Description:</strong></p> <p>These are velocity profile data from vessel towed ADCP obtained in the Sapelo Sound during a survey conducted on Sep. 13-15, 2000, which includes 16-hour stationary mooring measurements, a 16-hour continuous survey along a triangle (14 Sep, 06:21 14 Sep, 22:01 UTC), and overnight mooring for ~ 13 hours. The instrument was an RDI 600 KHz Workhorse ADCP.</p> <p>The ADCP was mounted on a sled towed by the boat. The vertical bins were 0.5 m. The surveys were conducted at an average cruise speed of about 2.5&ndash;3 m/s except at the turns when the vessel had to slow down and during CTD casts when the vessel had to stop for a few minutes. A Seabird Electronic SBE 19 plus CTD was used. Note that only ADCP data are included in this dataset.</p> <p>The data are averaged at about 30-second intervals, excluding bad data. The data presented here are in ASCII with the generic format provided by the RDI&rsquo;s software WinRiver II output. There are three data files:</p> <p>ALT00T.000</p> <p>ALT00T.001</p> <p>ALT00T.002</p> <p>Here is an example of the data &ndash;</p> <p>50&nbsp;&nbsp;&nbsp;&nbsp; 50&nbsp;&nbsp;&nbsp;&nbsp; 25&nbsp;&nbsp;&nbsp;&nbsp;
