LTER Georgia Coastal Ecosystems - September 2003 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Altamaha River transect
Listed in NASA Earthdata CMR
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).
Description
Vertical CTD profiles were collected at 2km intervals from the -4km to 26km upriver along the transect during various tidal regimes. Conductivity, temperature, pressure and optical backscatter were measured, and depth, salinity and sigma-t were calculated for each profile.
Data values collected on the upcast were deleted, and the remaining data were averaged within 0.5m depth bins and interpolated to produce a smooth profile for contouring. 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.
