LTER Georgia Coastal Ecosystems - June 2003 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Intracoastal Waterway transect

Two hydrographic surveys were performed from June 18 to June 19, 2003, along
the Intracoastal Waterway between the Altamaha River south of Wolf Isand and
Sapelo Sound (Intracoastal Waterway Transect, GCE-IC). Vertical CTD profiles
were collected at various intervals from 0km to 23km 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-IC -- Intracoastal Waterway, Georgia, USA. Intracoastal
Waterway transect used for GCE quarterly hydrographic monitoring surveys.
Nominal profiling stations are defined at varying distances from -28km to 32km
(South to North, relative to station 0km at the sourthernmost tip of Wolf
Island near the mouth of the Altamaha River), based on an estimated Thalweg
line running up the main channel.
