December 2003 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Intracoastal Waterway transect

Two hydrographic surveys were performed from December 2 to December 3, 2003, along the Intracoastal Waterway between the Altamaha River south of Wolf Island and Sapelo Sound (Intracoastal Waterway Transect, GCE-IC). Vertical CTD profiles were collected at various intervals from -17km to 26km along the transect during flood and ebb tidal regimes Conductivity, temperature, pressure, optical back scatter, photosynthetically-available radiation, oxygen and chlorophyll a fluorescence were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected during the upcast were deleted. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.
