Title:

Continuous salinity, temperature and depth measurements from moored hydrographic data loggers deployed at GCE7_Hydro (Altamaha River near Carrs Island, Georgia) from 01Jan2011 through 31Dec2011

Abstract:

Conductivity, temperature and pressure were measured continuously at Georgia Coastal Ecosystems LTER sampling location GCE7_Hydro (Altamaha River near Carrs Island, Georgia) from 01Jan2011 through 31Dec2011. Observations were logged at 30 minute intervals by moored SeaBird Electronics MicroCAT 37SM data loggers and downloaded approximately semimonthly. Salinity, depth and sigmat (density anomaly) were calculated from the measured parameters using standard UNESCO algorithms. This data set was collected as part of the GCELTER Project continuous salinity, temperature and water level monitoring program.
