GCE-LTER Data Set Summary

Accession: PHY-GCEM-0310d2 Research Theme: Physical Oceanography (Monitoring)
Contributors: Daniela Di Iorio, KiRyong Kang
Title: September 2003 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Duplin River transect
Abstract: Two hydrographic surveys were performed on September 24 and September 25, 2003, along an south-to-north transect up the Duplin River on Sapelo Island, Georgia (Duplin River Transect, GCE-DP). Vertical CTD profiles were collected at various nominal stations along the transect during various tidal conditions. 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.
