Spring 2001 CTD profiles for the Georgia Coastal Ecosystems Intracoastal Waterway transect

Five hydrographic surveys were performed between May 29 and June 5, 2001, along the Intracoastal Waterway between the Altamaha River south of Wolf Island and Sapelo Sound. Vertical CTD profiles were collected at approximately 1-3km intervals from 0km to 32km along the transect during various tidal regimes. Conductivity, temperature, pressure and optical backscatter were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected on the upcast were deleted, and the remaining data were averaged within 0.5m depth bins and interpolated to produce a smooth profile for contouring. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.
