Near-Surface Spatial Water-Quality Surveys along the Caloosahatchee River in June and July 2021, south Florida

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River on June 21-22 and July 20, 2021, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescence of dissolved organic matter were recorded

Near-Surface Spatial Water-Quality Surveys along the Caloosahatchee River and St. Lucie River in July 2020 and the Caloosahatchee River in September 2020, south Florida

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River and St. Lucie River July 13-15, 2020 and the Caloosahatchee River September 22 and 23 of 2019, south Florida. The St. Lucie portion of the surveys was not able to be completed in September due to boat engine failure. Geo-referenced measurements of near surface water temperatu

Near-Surface Spatial Water-Quality Surveys along the St. Lucie and Caloosahatchee Rivers in October 2017, Lake Okeechobee and Caloosahatchee River in July 2018, and Caloosahatchee River, St. Lucie River and Lake Okeechobee in August of 2018, south Florida

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the St. Lucie and Caloosahatchee Rivers in October 2017, Lake Okeechobee and the Caloosahatchee River in July 2018 and the Caloosahatchee River, St. Lucie River and Lake Okeechobee in August of 2018, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, d

Calculated carbon concentrations, loads and flux, in Big Cypress National Preserve, southern Florida, 2015-2017

This data release provides data for quantifying the aquatic export of total carbon in a cypress swamp within the Big Cypress National Preserve, and is part of a larger carbon budget study. The U.S. Geological Survey operated two continuous streamflow and water-quality monitoring stations within the Big Cypress National Preserve in southern Florida from September 2015 to October 2017. Site-specific

Near-Surface Spatial Water-Quality Surveys along the Caloosahatchee River, St. Lucie River and Lake Okeechobee in July and August 2019, south Florida

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River, St. Lucie River and Lake Okeechobee July 15-18 and August 19-21 of 2019, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescence

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

PRMS simulator used to assess rainfall, runoff, and river flow for the National Hydrologic Model (NHM) Puerto Rico

The National Hydrologic Model (NHM) is a modeling framework which has been applied to the continental United States through the Precipitation Runoff Modeling System (PRMS). The PRMS model of Puerto Rico extends the NHM and allows the simulation of rainfall-driven hydrologic conditions in the Commonwealth. Calibration of the NHM Puerto Rico model involved an initial manual calibration to understand

Quantitative polymerase chain reaction (qPCR) cyanotoxin data for eight mesocosm experiments in the Caloosahatchee River, Florida from May 2019 through August 2021

An interdisciplinary and multiagency study was conducted in southern Florida to examine harmful algal bloom (HAB) dynamics on the Caloosahatchee River, which drains from Lake Okeechobee to the west into the Gulf of Mexico. Using in-situ mesocosm experiments, ammonium, nitrate, phosphate, and urea were altered from ambient conditions to determine the effects on cyanotoxin biosynthesis gene presence

Quantitative polymerase chain reaction (qPCR) cyanotoxin data for 21 sites on Lake Okeechobee and the Okeechobee waterway, Florida, USA collected monthly from March 2019 through October 2021

Quantitative polymerase chain reaction (qPCR) data were compiled for the biosynthesis genes of five toxins of interest produced by cyanobacteria as well as an internal control. Sample deoxyribonucleic acid (DNA) were collected from 21 sites which includes 17 sites from Lake Okeechobee, and four sites from the Caloosahatchee River and the St. Lucie River. Samples were collected on a monthly basis f

Caloosahatchee River Nutrient Enrichment Mesocosms: Phytoplankton Taxonomic Quantification September 2019, June 2020, September 2020, February 2021

An interdisciplinary and multiagency study was undertaken to study harmful algal bloom (HAB) dynamics on the Caloosahatchee River, which drains to the west from Lake Okeechobee into the Gulf of Mexico. Algae and cyanobacteria play crucial roles in aquatic ecosystems, but under favorable environmental conditions certain taxa may experience population growth booms resulting in HABs. Four independent

Decompartmentalization Physical Model (South Florida Water Management District) Periphyton Abundance and Biovolume Data 2017–21

Periphyton is a complex community of detritus, bacteria, fungi, and algae that grows attached to submerged substrates. Assemblage structure data for algae and cyanobacteria from periphyton samples were collected on a monthly basis from 2017 to 2021. Compiled data were reported as absolute abundance (cells) and biovolume per volume as well as absolute abundance (cells) and biovolume per area at fou
