Water for Birds—A spreadsheet-based tool for the Malheur National Wildlife Refuge for irrigation months in 2021–2024 Water for Birds—A spreadsheet-based tool for the Malheur National Wildlife Refuge for irrigation months in 2021–2024
A spreadsheet-based model (using Microsoft Excel) was developed to assess the amounts and types of habitats within the Malheur National Wildlife Refuge in southeastern Oregon, USA. The Refuge provides critical bird habitat, and the model was designed to quantify the areas of open water, partial water, and water depths during the irrigation season (April–July) from 2021–2024. This data...
Carmel River Basin Hydrologic Models: Future Climate Data Carmel River Basin Hydrologic Models: Future Climate Data
This digital dataset contains the gridded future climate data used for the Carmel River Basin Hydrologic Model. The daily climate data for the Carmel River Basin Hydrologic Model Hydrologic Model are based on the Salinas and Carmel River Basins Study (SCRBS) future climate scenarios (Henson and others, 2024). SCRBS considers one baseline climate scenario that represents recent historical...
Timelapse and webcam images of the 2022 eruption of Mauna Loa, Island of Hawaiʻi Timelapse and webcam images of the 2022 eruption of Mauna Loa, Island of Hawaiʻi
The 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi, was the first eruption on the volcano since 1984, producing a 17 km lava flow that threatened a major highway (Mulliken and others 2024; Zoeller and others 2024). The eruption began with lava fountaining in the summit caldera (Mokuʻāweoweo) at 23:21 HST on November 27, transitioning to vents on the Northeast Rift Zone (NERZ) by...

This data release contains macro and microscale datasets describing the abundance, valence states, and mineral residence(s) of chromium, iron, and manganese in natural and synthetic mineral mixtures used in laboratory experiments designed to simulate dynamic conditions in an engineered aquifer system [see Izbicki and Groover (2018) and Miller and others (2020)]. The landing page contains...
Topographic datasets compiled for the Lower Roanoke River corridor in 2003, 2014, and 2020, North Carolina Topographic datasets compiled for the Lower Roanoke River corridor in 2003, 2014, and 2020, North Carolina
This data release contains topographic information compiled for the Lower Roanoke River corridor located in eastern North Carolina. The Lower Roanoke River corridor includes the mainstem of the Roanoke River from Roanoke Rapids, NC (below the Roanoke Rapids dam) to the mouth of the Roanoke River at its confluence with the Albemarle Sound, and the associated floodplains and wetland areas
Supplementary Data Release for Framework for Mapping Liquefaction Hazard-Targeted Design Ground Motions Supplementary Data Release for Framework for Mapping Liquefaction Hazard-Targeted Design Ground Motions
These data are supplementary to the journal article Makdisi, A.J., Kramer, S.L. (In-Review). Framework for Mapping Liquefaction Hazard-Targeted Design Ground Motions (doi to be updated on full publication). This dataset includes tabular data summarizing mean and standard deviation liquefaction factor of safety (FSL) ratios, effective FSL return periods, and example reference liquefaction...
Cyanotoxin Concentrations in Extracts from Solid Phase Adsorption Toxin Tracking (SPATT) and Diffusive Gradients in Thin-Films (DGT) Samplers in Owasco Lake, Seneca Lake, and Skaneateles Lake, Finger Lakes Region, New York, 2019 Cyanotoxin Concentrations in Extracts from Solid Phase Adsorption Toxin Tracking (SPATT) and Diffusive Gradients in Thin-Films (DGT) Samplers in Owasco Lake, Seneca Lake, and Skaneateles Lake, Finger Lakes Region, New York, 2019
This data release contains dissolved cyanotoxin concentrations for microcystins (MC), cylindrospermopsins (CYL), anatoxins (ATX), and saxitoxins (STX) assessed using enzyme-linked immunosorbent assays (ELISA) and liquid chromatography-mass spectrometry or tandem mass spectrometry (LC-MS and LC-MS/MS, respectively) in extracts from SPATT (n=95) and DGT samplers (n=10) deployed on three...
Evaluating Seawater Intrusion Forecast Uncertainty under Climate Change in Pajaro Valley, California: Model Archive Evaluating Seawater Intrusion Forecast Uncertainty under Climate Change in Pajaro Valley, California: Model Archive
Climate change and climate variability impacts such as rising sea levels have the potential to exacerbate seawater intrusion and the strain on coastal freshwater resources in already stressed groundwater basins such as those in the Pajaro Valley groundwater basin, California. The U.S. Geological Survey (USGS) developed the Pajaro Valley Hydrologic model (PVHM) to quantitatively assess...
Illinois River basin seasonally dynamic total nitrogen and phosphorus SPARROW model inputs and outputs, 2000 through 2020 Illinois River basin seasonally dynamic total nitrogen and phosphorus SPARROW model inputs and outputs, 2000 through 2020
This data release contains seasonal source-specific estimates of total nitrogen (TN) and total phosphorus (TP) loading to streams across the Illinois River basin (25,620 reaches) for 21 years from 2000 through 2020 using a dynamic SPARROW (Spatially Referenced Regressions on Watershed attributes) model. Input data including calibration loads, output predictions, model control files, and...
MODFLOW-6 model of variable-density groundwater flow and brine discharge to the Dolores River in the Paradox Valley, Colorado MODFLOW-6 model of variable-density groundwater flow and brine discharge to the Dolores River in the Paradox Valley, Colorado
MODFLOW-6 with the Groundwater Flow (GWF) and Groundwater Transport (GWT) models was used to simulate the geohydrology of the aquifer system of the Paradox Valley in western Colorado. Salinity of the Colorado River is a major concern in both the United States and the Republic of Mexico. The Colorado River and its tributaries supply water for about 40 million people and irrigation of...
Microbial Communities Across a Successional Gradient at Indiana Dunes National Park, 2015-2017 Microbial Communities Across a Successional Gradient at Indiana Dunes National Park, 2015-2017
This soil and vegetation data were collected along a successional gradient at the Indiana Dunes National Park. Soil samples were processed for standard soil chemistry, texture, and nutrients. DNA extracted from soil samples were analyzed for bacterial communities using 16S rRNA amplicon sequencing technique to understand the composition and distribution of these communities along the...
Hexane extractable material in water-based and oil-based drilling fluid wastes collected from sites in Oklahoma, North Dakota, and Wyoming in 2021 Hexane extractable material in water-based and oil-based drilling fluid wastes collected from sites in Oklahoma, North Dakota, and Wyoming in 2021
Wells drilled during oil and gas exploration use drilling fluids to cool and lubricate the drilling bit and clear the borehole of cuttings. These fluids are recycled during the drilling process, but eventually can no longer be used. This is an important waste stream from petroleum generation that requires disposal. Chemical characterization of these materials is important to determine if...
