Description:
Rainfall and Runoff as a Source of Organic Carbon Additions to Bayou Texar, Florida (Abstract). To be presented at the16th Biennial Conference of the Estuarine Research Foundation, ERF 2001: An Estuarine Odyssey, 4-8 November 2001, St. Pete Beach, FL. 1 p. (ERL,GB R852).
This study examined the relationship between precipitation and organic carbon concentrations in Bayou Texar, Florida. Rainfall and runoff are potentially important vectors for allochthonous organic materials, carrying dissolved and particulate matter into estuarine waters via rainfall and runoff. In this study, weekly water samples were collected between March and June, 1999 from five stations in Bayou Texar. On several occasions, higher frequency (every 2 hours) data were collected to capture rain events. Pulses of particulate organic carbon (POC), dissolved organic carbon (DOC), and nutrients were detected in the bayou during rain events; however these data suggested that each component was quickly diluted. Rainfall and runoff had no
measurable impacts on the carbon concentrations over daily to monthly time scales. Nutrient concentrations were replete during the sampling period, implying that additions via precipitation increased concentrations but did not stimulate phytoplankton growth.
