Current velocity data from a quasi-continuous survey using ADCP in Satilla River Estuary, Georgia.

<p><strong>Title:&nbsp; </strong>Current velocity data from a quasi-continuous survey using ADCP in Satilla River Estuary, Georgia.</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 Satilla River Estuary during a survey conducted on 17&ndash;18 November 2004. The instrument was an RDI 600 KHz Workhorse ADCP. The survey was done mostly during daylight time along a 90-degree bend in the middle of the Satilla River Estuary. The observations covered nearly two semidiurnal tidal cycles with 15 repetitions and 33 hours in measurement time. The route is about 11 km in length and covers both the West and East sides of the bend of the channel. Note that tide in this area is essentially semidiurnal which makes 12-h observations sufficient to resolve the main tidal constituents.</p> <p>The ADCP was mounted on one side of the boat approximately 0.4 m below the surface. 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 to measure the vertical profiles of water temperature, salinity, fluorescence, light attenuation, and dissolved oxygen at two to three locations during each survey. Note that only ADCP data are included in this dataset.</p> <p>The data are averaged at about 8-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 a total of seven data files. There are:</p> <p>&nbsp;</p> <p>ADCP_Nov17_2004_Satilla_River_000t.000</p> <p>ADCP_Nov17_2004a_Satilla_River_000t.000</p> <p>ADCP_Nov17_2004a_Satilla_River_001t.000</p> <p>ADCP_Nov17_2004a_Satilla_River_002t.000</p> <p>ADCP_Nov18_2004a_Satilla_River_000t.000</p> <p>ADCP_Nov18_2004a_Satilla_River_001t.000</p> <p>ADCP_Nov18_2004a_Satilla_River_002t.000</p> <p>Here is an example of the data &ndash;</p> <p>&nbsp;&nbsp;&nbsp;
