Images of the seafloor off the Kona coast of the Island of Hawai`i were collected by the United States Geological Survey in 2003, 2004, and 2022, during field activities A803HW, A204HW, A604HW, and 2022-615-FA. The images were acquired in cooperation with the National Park Service, primarily in the waters off Kaloko-Honokohau National Historical Park, Pu`ukohola Heiau National Historic...

This U.S. Geological Survey (USGS) data release includes whole-rock major, trace, and rare earth element geochemical data, whole-rock Nd-Pb-Sr isotopic data collected by thermal ionization mass spectrometry (TIMS), and zircon U-Pb isotopic data collected by laser ablation-inductively coupled mass spectrometry (LA-ICP-MS) methods. These data provide constraints on, and characterize, the...

This dataset provides a predictive ecological state map for the Southwest Sandy and Loamy Uplands Ecological Site Group (ESG). We developed a machine learning approach to predict ecological states by training vegetation cover data from three remotely sensed datasets—Rangeland Analysis Platform (RAP), Rangeland Condition Monitoring Assessment and Projection (RCMAP), and Landscape Cover...

Data was collected in association with the exposure of aqueous nickel (NiCl2-H2O) to juvenile crayfish (Faxonius virilis) for 29 days at different concentrations to observe any differences in growth (after 28 days) and food consumption (on day 29). Data for the growth component of the study included crayfish wet weight (initial and final), final carapace length, and crayfish sex. The...

This dataset consists of three turbidite sandstone samples that were analyzed for U-Pb detrital zircon ages. The dataset accompanies the publication "An empirical test of Maximum Depositional Age through paired LA-ICP-MS and CA-ID-TIMS detrital zircon analysis: implications for the "Nevadan orogeny" in the Sierra Nevada foothills, California, U.S.A.", as well as planned future...

These data were compiled to evaluate the impacts of large-scale solar energy development on wind-borne dust production. Objectives of the study were to evaluate dust produced during construction and operation of solar energy facilities constructed using varying construction methods. We also collected data on plant and soil variables that are known to be important predictors of dust...

The orthomosaic, digital surface model and point cloud presented here document conditions at Pickle Pond in Superior, Wisconsin in September 2022, prior to planned ecological restoration. Images were collected using a 3D Robotics Solo aircraft with GNSS GPS upgrade, Mission Planner software, and a Pentax Ricoh GRII 3-band digital camera sensor. Imagery acquisition flights were...

Bathymetric, topographic, and grain-size data were collected in May 2014 along a 27 mile (43.5 kilometer) reach of the Colorado River in Grand Canyon National Park, Arizona. The study reach begins at river mile 61.1, about 0.6 miles (1 kilometer) above the confluence of the Colorado and Little Colorado Rivers and ends at river mile 88.1 at the upstream boundary of the Bright Angel Rapid...

Chronic selenium toxicity thresholds are based primarily on dietary organoselenium exposure and subsequent reproductive effects in fish. Available chronic selenium toxicity data suggests that invertebrates are less sensitive than fish, but chronic invertebrate studies are limited. We evaluated yeast-based diets for chronic toxicity studies with Hyalella azteca and Chironomus dilutus...

This dataset represents coarse active relocations of acoustic transmitters in telemetry tagged fish of various species detected among the Mississippi and Missouri rivers near their confluence. These detections of unknown tagged individuals were incidental and occur within the range and frequency of effort for a focused active telemetry study on invasive carp. These river segments consist...

This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR) and projected coastal storms. Products include projected flood depths, flood extents including uncertainties, water elevations, wave heights, velocity hazards, and erosion and sedimentation patterns. These are generated using a suite of numerical models driven by outputs from...

The dataset is an inventory (enumeration and taxonomic identification) of mollusk diet items consumed by wild-caught black carp (Mylopharyngodon piceus), based on the examination of gut contents from black carp collected in the lower Mississippi River drainage of the U.S. in 2019 through 2023.
