Data for Bathymetric Survey and Sedimentation Analysis of Lago Carite, Puerto Rico, January 2018 Data for Bathymetric Survey and Sedimentation Analysis of Lago Carite, Puerto Rico, January 2018
This data release contains spatial data associated with the bathymetric survey and sedimentation analysis of Lago Carite in January 2018. During January 23-30, 2018, the U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, conducted a bathymetric survey of Lago Carite primarily to update estimates of the contemporary reservoir storage capacity and...
Underwater Videographic Observations of Cultured Delta Smelt in Field Enclosures: Video Clips and Summary Data Underwater Videographic Observations of Cultured Delta Smelt in Field Enclosures: Video Clips and Summary Data
All data is part of a pilot study aimed to observe Delta Smelt behavior within enclosures deployed in the wild. The enclosures used were designed by The California Department of Water Resources and UC Davis as part of their ongoing Delta Smelt enclosure deployment studies. Study 1: This data includes 16 17:43 minute videos of observations of Delta Smelt behavior in a floating field...
Cliff Feature Delineation Tool and Baseline Builder, Version 1.0 Cliff Feature Delineation Tool and Baseline Builder, Version 1.0
The CFDT is an automated computer vision application designed to generate 3D line features representing the seacliff top, midpoint, and toe on high-relief coastal cliffs. The program also delineates 3D points on concavities and convexities across the cliff face (termed subsidiary features), which may represent talus deposits, secondary cliff tops, and secondary cliff toes. The tool...
Gila River at I-10 Bridge near Sacaton, AZ - 2020/08/12 GPS Survey Gila River at I-10 Bridge near Sacaton, AZ - 2020/08/12 GPS Survey
The dataset contains GPS survey data of ground control points deployed for aerial LiDAR data collection. The targets were deployed and surveyed on 8/12/2020 and the LiDAR flight was conducted on the morning of 8/13/2020. The control points were surveyed using Leica GS14 RTK GPS equipment, S/N rover-2806883, using the Real Time Network, Leica Smartnet, to determine absolute position.
Water Temperature, Dissolved Oxygen, and pH Point Measurements from a Beaver Pond along Fanno Creek, Oregon, on four hot days in summers 2016-17 Water Temperature, Dissolved Oxygen, and pH Point Measurements from a Beaver Pond along Fanno Creek, Oregon, on four hot days in summers 2016-17
Water-quality point measurements were collected at various depths throughout a beaver pond along Fanno Creek in the Tualatin River Basin, Oregon. Parameters collected include water temperature, dissolved oxygen, and sometimes pH. All data were collected over a short period of time ( 4 hours) during 4 hot days in order to characterize the spatial (both horizontal and vertical) variability...
Combined wildfire datasets for the United States and certain territories, 1878-2019 Combined wildfire datasets for the United States and certain territories, 1878-2019
This dataset is comprised of four different zip files. Zip File 1: A combined wildfire polygon dataset ranging in years from 1878-2019 (142 years) that was created by merging and dissolving fire information from 12 different original wildfire datasets to create one of the most comprehensive wildfire datasets available. Attributes describing fires that were reported in the various source...
Chemical and biological data from acute and chronic nickel and zinc exposure bioassays to two sensitive freshwater benthic invertebrates Chemical and biological data from acute and chronic nickel and zinc exposure bioassays to two sensitive freshwater benthic invertebrates
The responses (survival, growth, and/or reproduction) of test organisms in six concentrations of toxicants in acute and chronic tests. Chemical and water quality parameters were measured for quality assurance and quality control purposes.

Understanding how data are used across the scientific community provides many benefits to data authors, including building a better awareness and comprehension of 1) a dataset's scientific impact, 2) use cases to direct future versions, and 3) related efforts. Effectively tracking when and how data are used in the literature through time can be challenging. This is in part due to a lack...
Data used to describe hydrogeologic units and create contour maps and cross sections of the Boone and Roubidoux Aquifers, northeastern Oklahoma Data used to describe hydrogeologic units and create contour maps and cross sections of the Boone and Roubidoux Aquifers, northeastern Oklahoma
The Ozark Plateau aquifer system stretches across approximately 70,000 square miles (mi2) of Arkansas, Missouri, Kansas and Oklahoma, and is composed of many hydrogeologic units, such as the Boone aquifer and the Roubidoux aquifer. However, this data release is focused on only 11,000 mi2 in northern Arkansas, southeastern Kansas, southwestern Missouri, and northeastern Oklahoma. The...
Machine-learning model predictions and groundwater-quality rasters of specific conductance, total dissolved solids, and chloride in aquifers of the Mississippi embayment Machine-learning model predictions and groundwater-quality rasters of specific conductance, total dissolved solids, and chloride in aquifers of the Mississippi embayment
Groundwater is a vital resource in the Mississippi embayment of the central United States. An innovative approach using machine learning (ML) was employed to predict groundwater salinity - including specific conductance (SC), total dissolved solids (TDS), and chloride (Cl) concentrations - across three drinking-water aquifers of the Mississippi embayment. A ML approach was used because...
Lamprey Larvae Carcasses following Exposure to 3-trifluoromethyl-4-nitrophenol (TFM) or TFM plus 1% Niclosamide Data Lamprey Larvae Carcasses following Exposure to 3-trifluoromethyl-4-nitrophenol (TFM) or TFM plus 1% Niclosamide Data
To evaluate how bigheaded carps use a restored backwater habitat, their passages into and out of and residency within a backwater was monitored using acoustic telemetry. This dataset describes the results of this study and was used to compare activity of bigheaded carps between species, at a diel scale, among seasons, and how activity related of environmental conditions. Calculation of...
Measurements of bed grain size on the Colorado River in Grand Canyon National Park, Arizona - 2000 to 2014 Measurements of bed grain size on the Colorado River in Grand Canyon National Park, Arizona - 2000 to 2014
These data were compiled to better understand sedimentation patterns on the bed of the Colorado River in Grand Canyon National Park, and the way these patterns relate to suspended sediment grain size and concentration. These data were collected by the US Geological Survey Grand Canyon Monitoring and Research Center from 2000 to 2014, primarily using the "Flying Eyeball" underwater...
