Spring 2001 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Altamaha River transect

A series of four hydrographic surveys were performed from May 30 through June 4, 2001, along an east-to-west transect up the Altamaha River in Georgia. Vertical CTD profiles were collected at 1-2km intervals from 4km east of the line of demarcation (station -4) to 28km upriver along the transect during various 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.
