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

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) 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

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

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

A Geographic Information System (GIS) shapefile and summary tables of irrigated agricultural land-use are provided for the 15 counties fully within the Northwest Florida Water Management District (Bay, Calhoun, Escambia, Franklin, Gadsden, Gulf, Holmes, Jackson, Leon, Liberty, Okaloosa, Santa Rosa, Wakulla, Walton, and Washington counties). These files were compiled through a cooperative project b

This data release consists of four network Common Data Form (netCDF) files of bias-corrected daily precipitation at 1-kilometer (km) scale for historical and projected climate of Puerto Rico. The Weather Research and Forecasting (WRF) model was used by Bowden and others (2018) to downscale two general circulation models (GCMs) from the Coupled Model Intercomparison Project phase 5 (CMIP5): (1) the

This data release provides topographic (horizontal and vertical) data for 78 sites, surveyed from November 2017 to July 2019 as part of documentation of flooding that occurred in Puerto Rico during and after Hurricane Maria (September to November 2017). Hurricane Maria made landfall the Island of Puerto Rico on September 20, 2017 and was one of the deadliest storms in U.S. history. The U.S. Geolog

A Geographic Information System (GIS) shapefile and summary tables of irrigated agricultural land-use are provided for Lake, Marion, and Orange Counties, Florida compiled through a cooperative project between the U.S Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Policy. Information provided in the shapefile includes the location of

A Geographic Information System (GIS) shapefile and summary tables of irrigated agricultural land-use are provided for the fourteen counties that are fully or partially within the Suwannee River Water Management District, Florida compiled through a cooperative project between the U.S Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Pol
