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

Four hydrographic surveys were performed on September 26, 2003, along an
east-to-west transect up the Altamaha River in Georgia (Altamaha River
Transect, GCE-AL). Vertical CTD profiles were collected at 2km intervals from
the -4km to 26km 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.

GCE Study Site GCE-AL -- Altamaha River, Georgia, USA. Altamaha River transect
used for GCE quarterly hydrographic monitoring surveys. Nominal profiling
stations are defined every 2km from -4km to 40km (relative to station 0km at
the line of demarcation), based on an estimated Thalweg line running up the
main river channel.
