GCE-LTER Data Set Summary

Accession: PHY-GCEM-0211c2 Research Theme: Physical Oceanography (Monitoring)
Contributors: Daniela Di Iorio, KiRyong Kang
Title: November 2001 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Sapelo River transect
Abstract: One hydrographic survey was performed on November 26, 2001, along a transect from Sapelo Sound up the Sapelo River to Eulonia, Georgia (Sapelo River Transect, GCE-SP). Vertical CTD profiles were collected at approximately 3km intervals from 0km to 12km 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.
