Title:

Quarterly porewater salinity and conductivity measurements from the GCE-LTER Seawater Addition Long-Term Experiment (SALTEx) Project

Abstract:

The Georgia Coastal Ecosystems LTER Seawater Addition Long-Term Experiment (SALTEx) is a large-scale field experiment designed to simulate saltwater intrusion in a tidal freshwater wetland to predict how chronic (Press) and acute (Pulse) salinization will affect this and other tidal freshwater ecosystems. Thirty porewater well samples were collected every 2-3 months from all 30 treatment plots using a peristalsis pump. Salinity, conductivity and water temperature were measured from the samples using a handheld conductivity/salinity meter.
