Daily evaporation rates were calculated at the open-water LZ40-platform in the interior of Lake Okeechobee, Florida, from December 1, 2012 through December 31, 2016 using five methods (Shoemaker et al., 2024); specifically, the Penman, Priestly-Taylor, Mass-Transfer, Simple, and Turc equations. Bowen-ratio energy-budget derived daily evaporation rates calculated from micro-meteorological data at the LZ40 site (Wacker, 2020) are considered a standard by which to evaluate the five alternative evaporation methods. Parameterization of each of method and comparison of evaporation using each of the five methods to the Bowen ratio estimates are published by Shoemaker and others (2024).

A reach of the North Santiam River, Oregon, was used as a case study in an ongoing effort to develop and test uncrewed aircraft system (UAS)-based salmon habitat mapping techniques using: (1) particle image velocimetry (PIV) for estimating surface flow velocities from remotely sensed data; and (2) two-dimensional (2D) flow modeling based on remotely sensed topography and bathymetry (topo-bathymetry). Direct measurements of flow velocity were obtained using an acoustic Doppler current profiler (ADCP) and used to assess the accuracy of the image-derived velocity estimates and modeled flow fields. Water depth was measured using a single beam echosounder and was used to calibrate and validate image-derived depth estimates...

Daily measurements of evaporation using the Bowen ratio method were made at USGS station name LZ40 (USGS site number 265405080472100), a platform-based station constructed by the South Florida Water Management District (SFWMD) at the approximate center of Lake Okeechobee, Florida. Data collection began on November 15, 2012. Meteorological and environmental variables were measured every 30 seconds and averaged at 30-minute resolution until February 7, 2013 and 15-minute resolution thereafter to December 31, 2019, including: precipitation, air temperature, relative humidity, wind speed, incoming/outgoing solar radiation, and water temperature at various depths.
This project contains field data and supporting files for a Lagrangian particle tracking (LPT) model at a representative reach on the Osage River, Missouri. Field datasets include a topobathymetric digital elevation model (DEM) for a 5-km reach of the Osage River, water surface elevation profiles, and velocity data collected with acoustic Doppler current profiler (ADCP). Channel topography was generated from data collected by USGS staff from the Columbia Environmental Research Center during single beam sonar surveys of the channel bed and high-resolution Real Time Kinematic Global Navigation Satellite Systems for positioning. Field data was used to generate and validate a Lagrangian Particle Tracking model to evaluate...
This dataset includes CSV data files containing environmental data that may be associated with the occurrence and toxicity of the diatom Pseudo nitzschia in Frenchman Bay, Maine, that can form harmful algal blooms and produce the toxin domoic acid. The dataset covers the period 2010 through 2022 or shorter period depending on the variable. Elevated concentrations of domoic acid in Pseudo nitzschia can lead to the contamination of shellfish, threats to human health and closures of shellfish harvesting areas. This dataset was compiled in cooperation with the National Park Service. The file “Site_Infomation_v4.csv” contains the latitudes and longitudes for the locations where Pseudo nitzschia cells were enumerated,...
The dataset contains a hybrid bathymetric-topographic digital elevation model (DEM) of the Osage River downstream from Bagnell, Missouri. Channel topography was generated from data collected by USGS staff from the Columbia Environmental Research Center during single beam sonar surveys of the channel bed in March through May 2022 and terrestrial light detection and ranging (LiDAR) surveys of channel banks in December 2021. Floodplain topography was generated from airborne LiDAR data downloaded from the Missouri Spatial Data Information Service (MSDIS).
This data release contains digital hydrogeologic datasets compiled for eight valley-fill aquifer systems in upstate New York. The data sets include input data necessary to create and interpolate the hydrogeologic framework of the aquifers and surrounding till-covered uplands. Input data is provided as point feature classes and georeferenced files of previously published reports along with the digitized data as line or polygon feature classes. Feature class datasets are provided for convenience and may contain subtle differences to shapefiles due to inherent differences in file types. The data release is composed of eight child items, one for each valley-fill area. Each child item contains the data pertaining...
The dataset consists of two longitudinal water surface profiles collected near river mile 72 of the Osage River downstream from Bagnell, Missouri. Water-surface elevation data were collected by USGS staff from the Columbia Environmental Research Center using Real Time Kinematic Global Navigation Satellite Systems (RTK GNSS) for the length of the study reach.
The United States Geological Survey (USGS) collected a total of 179 samples of surficial sediment from abandoned mine wastepiles, ephemeral channels, nearby outcrops, and background areas representative of the undisturbed lithology within the Silver Island and Crater Island mining districts (Krahulec, 2018).The samples were sieved to obtain the less than 177 micron fraction. Geochemical analyses were completed through a third-party contract by SGS Laboratories. Samples were analyzed for 49 major, minor, and trace elements using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) methods (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe,...

This data release contains a zipped folder with two comma delimited data files and two companion metadata files. The data files are: 1.) sap_flux_data.csv and; 2.) biophysical_characteristics_of_instrumented_trees.csv. The sap flux data were stored in data loggers every 10-minutes for 15 riparian trees. Sap flux was estimated using heat-pulse velocity sensors at three depths into the xylem of each tree. Sap flux estimates in the data release are 30-minute rolling medians which reduces data spikes that are common in high-frequency sap-flux data. The biophysical measurements are properties of the instrumented trees that allow scaling of sap flux to sap flow and total-tree water-use.
This data release contains inputs for and outputs from hydrologic simulations for the conterminous United States (CONUS) using the Precipitation Runoff Modeling System (PRMS) version 5.1.0 and the USGS National Hydrologic Model infrastructure (NHM, Regan and others, 2018). These simulations were developed to provide estimates of the water budget for the period 1950 to 2010. Specific file types include: 1) input atmospheric forcings of minimum air temperature, maximum air temperature, and daily precipitation accumulation derived from a gridded observation-based dataset developed by Maurer and others (2002), 2) input parameter files for static and dynamic land cover conditions, and 3) output files of simulated water...

Topobathy was surveyed during the fall of 2022 for two locations along Minnesota Point, where past beach nourishment (dredge materials) were placed. These topobathymetric surveys of Minnesota Point and Lake Superior are repeat surveys that will be used evaluate movement of placed material and overall change of near-shore bathymetry. The data was acquired using a lidar sensor, and single-beam and multibeam sonars. The data includes DEMs of the terrestrial beach areas and near-shore bathymetries of Lake Superior near the Duluth and Superior entries of Minnesota Point, 2-foot smoothed contours, LAS and XYZ files. Data were collected in cooperation with the U.S. Army Corps of Engineers (USACE), Detroit District.
