Benthic chamber data

Benthic chamber data from Silver River, Rainbow River, Gum Slough and Alexander Springs Creek, four spring fed rivers in north Florida. Dissolved oxygen measured using Onset HOBO U26, nitrate measured using Satlantic SUNA. Uptake within the chamber, isolated from resupply, produces nitrate depletion allowing us to examine concentration effects on uptake rates (i.e. reaction kinetics) and primary production (i.e. potential nutrient limitation). Note three chambers in Alexander Springs Creek were artificially enriched with nitrate, while five replicate chambers in Rainbow River were dosed with ammonium.
