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

Three hydrographic surveys were performed from September 25 to September 27,
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 -11km to 26km 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-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.
