Ephemeral Microbial Mats in the Satilla River

PIs: Deborah A. Bronk (Virginia Inst of Marine Science, College of William and Mary) and Samantha Joye (Dept of Marine Sciences, Univ of Georgia, Athens, GA, USA) 

Support: Georgia Sea Grant College Program (R/WQ-7-PD)

Timeframe: 3/1/99 - 2/28/01 (complete)

Project Overview:
The objective of this project development grant was to quantify environmental (physical, biological and chemical) characteristics of sites with blooms, versus those not experiencing blooms, to identify factors correlated with bloom formation.


  • Denitrification rates were quantified and the sediments were characterized.

  • The addition of nutrients to the Satilla River system via groundwater were also quantified.
