Calculated carbon concentrations, loads, and export in Big Cypress National Preserve, South 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 regression models were developed using continuously measured specific conductance and concomitant discretely collected total carbon (dissolved organic carbon, dissolved inorganic carbon, and particulate carbon) samples to calculate continuous concentrations of total carbon. Total carbon loads were calculated by multiplying...
This data release provides data for dissolved organic carbon concentrations calculated for USGS station number 02292900, Caloosahatchee River at S-79, NR. Olga, FLA. A site-specific regression model was developed using continuously measured specific conductance and fluorescence of chromophoric dissolved organic matter and concomitant discretely collected dissolved organic carbon samples to calculate continuous concentrations of dissolved organic carbon.
Data for the Hydrologic and Water-Quality Characterization of Caño Boquerón, Cabo Rojo, and Puerto Mosquito, Isla de Vieques, Puerto Rico, July 2015-July 2016
This data release contains the shapefiles and data associated with the assessment of the principal mechanisms affecting the hydrology and water-quality characteristics at Caño Boquerón in Cabo Rojo and at Puerto Mosquito on Isla de Vieques, Puerto Rico. The U.S. Geological Survey, in cooperation with the Puerto Rico Environmental Quality Board (PREQB), conducted a limnological study of these coastal waters to provide baseline information to the regulatory agencies responsible for the management and conservation of these coastal waters and the preservation of their aquatic life. Field measurements and water samples were collected and processed during July 2015–July 2016 for analysis of physical, chemical, biological,...
Data Pertaining to Mapping the Approximate Inland Extent of Saltwater at the Base of the Biscayne Aquifer in Miami-Dade County, Florida, 2018
The U.S. Geological Survey (USGS), in cooperation with Miami-Dade County, mapped the approximate inland extent of saltwater intrusion in eastern Miami-Dade County in 2018. This approximation required acquisition and compilation of relevant data collected by the organizations: Florida Department of Environmental Protection (FDEP), Florida Keys Aqueduct Authority (FKAA), Florida Power & Light Company (FPL), MacVicar Consulting Inc., Miami-Dade County Regulatory and Economic Resources (MD-RER), the South Florida Water Management District (SFWMD), and the USGS. Data from the selected monitoring wells were entered into a geographic information system (GIS) for analysis and mapping. The approximate saltwater interface...
