September 2003 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Duplin River transect

Two hydrographic surveys were performed on September 24 and September 25, 2003, along an south-to-north transect up the Duplin River on Sapelo Island, Georgia (Duplin River Transect, GCE-DP). Vertical CTD profiles were collected at various nominal stations along the transect during various tidal conditions. 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.
