Title:

Spring 2001 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Doboy Sound transect

Abstract:

A sequence of four hydrographic surveys were performed on June 1, 2001, along an east-to-west transect through Doboy Sound near Sapelo Island, Georgia. Vertical CTD profiles were collected at 2km intervals from 0km to 12km 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.
