(6) KEYWORDS: Satilla, Mooring A, current velocity (7) RESEARCH LOCATION: Satilla River Mooring A at SL+13.57 (2-character river code + 4-digit code for upstream distance from river mouth in km). Latitude: 30.993 degrees N; Longitude: 81.538 degrees W. Mean water depth was 10.0 meters. (8) EXPERIMENTAL DESIGNS AND METHODS: An InterOcean Systems Model S4 current meter (s/n 908) was moored 1.0 meter above bottom on a frame. One-minute vector averages of horizontal current speed and direction were recorded every six minutes beginning 26 March 1997 at 0000 GMT (YRDAY 85.0) and ending 27 April 1997 at 1200 GMT (YRDAY 117.5). East and north components were derived from the velocity vector. The coordinate system was then rotated 4 degrees counter-clockwise to align the rotated x-component with the along-channel direction; positive x-cur = EBB direction; positive y-cur = cross-channel, ~toward the north.
