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 mesocosm experiments were conducted in September 2019, June 2020, September 2020, and February 2021 to capture natural temporal variability in water quality and phytoplankton assemblages. The experimental installation consisted of three floating metal cradles each containing four fiberglass chambers filled with native...

PET and ETo were computed on the basis of solar radiation, meteorological data (min/max temperature, min/max relative humidity, and mean wind speed at 2-meter height), and shortwave blue-sky albedo data. Solar radiation was computed from Geostationary Operational Environmental Satellite (GOES) sensor data, blue-sky albedo was computed from the Moderate Resolution Imaging Spectrometer (MODIS) MCD43A1 BRDF/Albedo data product,...
Synthetic seismograms provide a means to calibrate (groundtruth) seismic-reflection profiles to specific subsurface stratigraphic features observed in one-dimensional core and geophysical log data acquired from wells. Independently, Walker Marine Geophysical Company and Geokinetics Incorporated used velocity data from 14 borehole-compensated sonic logs as input for specialized geophysical software to generate 14 synthetic seismograms. Velocity data from the sonic logs were converted to a synthetic seismic trace using synthetic-seismogram production software, reproduced either 5 or 8 times, and placed side-by-side to resemble a seismic-reflection profile. For each well, the synthetic seismogram was used to relate...
The U.S. Geological Survey (USGS), in cooperation with the Puerto Rico Environmental Quality Board, has compiled a series of geospatial datasets for Puerto Rico to be implemented into the USGS StreamStats application (https://streamstats.usgs.gov/ss/). These geospatial datasets, along with basin characteristics datasets for Puerto Rico published as a separate USGS data release (https://doi.org/10.5066/P9HK9SSQ), were used to delineate watersheds and develop the peak-flow and low-flow regression equations used by StreamStats.
In cooperation with the Puerto Rico Environmental Quality Board, the U.S. Geological Survey (USGS) calculated over 40 different basin characteristics as part of preparing the Puerto Rico StreamStats application. These data were used to update the peak flow and low flow regression equations for Puerto Rico. These datasets are raster representations of various environmental, geological, and land use attributes within the Puerto Rico StreamStats 2020 study area, and will be served in the Puerto Rico StreamStats 2020 application to describe delineated watersheds. The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and...

The primary goal of the Comprehensive Everglades Restoration Plan is to restore natural water flow through the Everglades. An approach known as decompartmentalization, which involves the removal of levees, canals, and other barriers to flow, has been suggested to aid in the restoration. In the region known as Water Conservation Area 3 (WCA-3), the L-67A and L-67C canals and levees, which bisect WCA-3 into WCA-3A to the north and WCA-3B to the south, are major barriers to natural flow. A test project for the decompartmentalization of WCA-3 has been initiated through the WCA-3 Decompartmentalization and Sheetflow Enhancement Physical Model (DPM). This flow-release test involves reconnecting WCA-3A and WCA-3B through...

Discharge through 13 water control structures in Florida was calculated using theoretical equations and coefficients and compared to USGS-published discharge from October 1, 2007 to September 30, 2019. The two daily mean discharges were not compared for any values below 10 cubic feet per second or if (1) any alterations were made to the published discharge to account for factors such as debris or construction; (2) any values were missing throughout the day; (3) the flow regime changed during the day; or (4) the published discharge was estimated. The structures compared include a mixture of sluice and radial gates with free and submerged conditions for orifice and weir flow. The theoretical discharges, published...

In the Atlantic Ocean and above the Miami Terrace off southeastern Florida, a total of nine CTD (conductivity, temperature, and depth) casts were performed using the 115-foot Research Vessel (R/V) Weatherbird II above the submerged Miami Terrace at the Miami pockmark and Key Biscayne pockmark from May 4 to May 8, 2016. A CTD is a package of electronic instruments and sampling devices that measure conductivity, temperature, and depth but also capable of measuring multiple chemical and physical parameters of the seawater column. A CTD cast measures the various seawater parameters while the package is lowered and raised in one or more cycles from onboard a ship as it drifts with an ocean current or steams along a predetermined...

The dataset includes a table in comma delimited format of daily evapotranspiration (ET) from 6/15/2017 to 1/21/2020 from an ET station in wetlands along the western perimeter of Lake Okeechobee, near Clewiston, Florida. The dominant plant cover at the study site is sawgrass (Cladium jamaicense) with secondary amounts of cattails and open water surfaces such as canals for boat navigation. Sawgrass and cattail height generally varies from less than 1 to 2.4 meters. The depth of water in the wetland averages less than 1 meter above land surface but exceeds 1.5 meters when water levels are high in Lake Okeechobee. In contrast, water levels were less than 1 meter below land surface in the wetland from May to June of...
This dataset is a polygon shapefile containing reservoir boundary of Lago Guayabal, and represents the contour at the spillway elevation. This polygon was used to constraint the extent of the Triangulated irregular network (TIN) model and ultimately, to generate contours from bathymetric data collected during a sedimentation survey conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. Field techniques used during the survey were similar to those...

The U.S. Geological Survey has compiled information on water withdrawal and use for Puerto Rico at 5-year intervals since 1980 to provide data for the management of the Commonwealth’s water resources. For 2015, water withdrawals and use were estimated for 78 municipalities from fresh groundwater and surface water in the categories of public use, domestic use, irrigation use, livestock, commercial use, industrial use, and mining use and both fresh groundwater and surface water and saline surface-water for thermoelectric power. Fourteen tables and one shapefile were compiled to provide water withdrawals by municipalities and other water use information.

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 Community Climate System Model (CCSM4 or CESM), and (2) the Centre National de Recherches Meteorologiques-CERFACS (CNRM). The two models were dynamically downscaled using WRF for a historical (1985-2005) time slice and a future time slice (2040–60) under the high greenhouse gas emission scenario known as Representative...
