ABSTRACT:

Grab sample nutrient data for Simms Creek and Santa Fe Drain 2013-2016, pre- and post-fertilization. Results published in Forest Ecology and Management.

ABSTRACT:

Longitudinal profiles of water chemistry from the Upper Colorado River starting at State Bridge CO and ending at Potash UT. Both profiles use the confluence with the Green River as the zero, with distances increasing upstream. Summer 2018 was a lower than average flow while summer 2019 was higher than average. Time series collected at USGS fixed sites along the profile during summer 2018 are also included.

ABSTRACT:

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. Resulting publication currently in review in Freshwater Science.

ABSTRACT:

High-frequency time-series solute measurements from the Santa Fe River at USGS 02322500 near Fort White FL (29°50'55''N, 82°42'55"W), and longitudinal profiles of solute chemistry along 24 km of the Lower Santa Fe River from River Rise (29°52'25''N, 82°35'29"W) to FL47 bridge (29°51'54''N, 82°44'24"W).
