Two studies were conducted to investigate the physical and biological processes contributing to the dissolved oxygen (DO) availability in the Skidaway River Estuary (SRE), Savannah, GA during the summer of 2005. A temporal study looked at changes in DO concentrations, Chlorophyll a concentrations, bacterial abundance, water depth, and salinity, every hour, for 26 hours, over both a neap and a spring tide. A spatial study looked at changes in the above variables at 5 sites along the SRE while following the tide inland during a neap high and low tide, and a spring high and low tide. DO concentrations varied between 3.82 and 5.98 mg O2/L during both studies. Statistical analysis results showed, temporally, physical variables had a stronger ability to predict behavior in DO than biological variables, and, spatially, there was a significant difference in DO between sites and between tides.
