(1) FILE NAME: 96mmdoca.sla (2) YEAR: 1996 (3) PI: Mary Ann Moran (4) OTHERS: Edward Sheppard, Joe Covert (5) DESCRIPTION OF DATA FILE: Dissolved organic carbon concentrations for the Satilla River at several sites during LMER 3. (6) KEYWORDS: Satilla, dissolved organic carbon, humic acid fraction, non-humic acid fraction, salinity, LMER 3. (7) RESEARCH LOCATION: All locations indicate distance upstream from beach head. (8) EXPERIMENTAL DESIGN AND METHODS: Water samples were filtered through GF-F filters in glass filtration units and stored at 4 degrees C until processing. Immediately before analysis, samples were acidified to pH 3.5 with 100% phosphoric acid, bubbled with CO2-free air for 2 minutes. Samples were then injected into a Shimadzu TOC 5000 carbon analyzer standardized with potassium biphthalate.
