LTER Georgia Coastal Ecosystems - September 2003 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Sapelo River transect

Three hydrographic surveys were performed on September 27, 2003, along a
transect from Sapelo Sound up the Sapelo River to Eulonia, Georgia (Sapelo
River Transect, GCE-SP). Vertical CTD profiles were collected at 3-4km
intervals from 0km to 36km during low and high 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-SP -- Sapelo River, Georgia, USA. Sapelo River transect
used for GCE quarterly hydrographic monitoring surveys. Nominal profiling
stations are defined every 3-4km from 0km to 36km (relative to station 0km at
the line of demarcation), based on an estimated Thalweg line running up the
main river channel.
