LTER Georgia Coastal Ecosystems - March 2004 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Altamaha River transect - nwpag2_LTER_GCE_PHY_GCEM_0404a1

Four hydrographic surveys were performed on March 13, 2004, along an
east-to-west transect up the Altamaha River in Georgia (Altamaha River
Transect, GCE-AL). Vertical CTD profiles were collected at 2-4km intervals from
the -4km to 24km upriver along the transect 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.
