GCE-LTER Data Set Summary

Accession: BCT-GCEM-0302c Research Theme: Bacterial Productivity (Monitoring)

Title: November 2001 surface water bacterial productivity at ten Georgia Coastal Ecosystems LTER sampling sites
Abstract: Surface water samples were collected during low tide survays near ten Georgia Coastal Ecosystem LTER sampling sites in November, 2001. The incorporation of tritiated leucine in unfiltered samples during one hour incubations was measured using a standard microcentrifuge method to estimate bacterial productivity in each sample. This study was part of the GCE-LTER hydrographic monitoring program, and will be repeated quarterly.
