Water-quality profiles within the Caloosahatchee River and twelve fiberglass tanks, during experimental nutrient addition treatments, 2019 This U.S. Geological Survey (USGS) data release provides water-quality data collected from the Caloosahatchee River and 12 fiberglass tanks located within the Caloosahatchee River. The tanks were open to the atmosphere, and were closed to the river. Tanks were filled with native water within 1-2 hours prior to the first profile collected on May 6, July 8, and September 16. Nutrients were added at approximately 12:00 p.m. on May 6, 11:45 a.m. on July 8, and 11:00 a.m. on September 16. Sodium nitrate was added for the nitrate treatments, sodium phosphate was added for the phosphate treatments, and ammonium hydroxide was added for the ammonium treatments. Nutrient samples were collected and processed by Nova Southeastern...

This dataset contains water quality sensor readings from two of eight total independent experiments conducted from June 8-11, 2020 and September 14-17, 2020. Each of the 12 tanks were randomly treated with either ammonium hydroxide, sodium nitrate, sodium phosphate, or left untreated (controls) for a total of three replicates of each treatment. The tanks were treated with incrementally...
