Geochemistry and x-ray diffraction data for hydrothermal manganese oxide rocks from the Samoa hotspot region in the South Pacific Ocean collected during research expedition KM0506 Geochemistry and x-ray diffraction data for hydrothermal manganese oxide rocks from the Samoa hotspot region in the South Pacific Ocean collected during research expedition KM0506
Hydrothermal manganese oxide rocks were collected via dredge from the Tulaga Seamount, the flank of Ofu Island, and from Soso seamount in the Samoa hotspot region offshore American Samoa during the KM0506 cruise aboard the R/V Kilo Moana in April of 2005. Rocks were subsampled at USGS and analyzed for mineralogy by x-ray diffraction as well as sent to SGS laboratories, Canada for major...
Data Examining the Effects of Fire Timing and Snow Depth on Plant Emergence Phenology Growth and Flowering in a Restored Tallgrass Prairie in Wisconsin from 2016–2023 Data Examining the Effects of Fire Timing and Snow Depth on Plant Emergence Phenology Growth and Flowering in a Restored Tallgrass Prairie in Wisconsin from 2016–2023
This dataset includes data from a study testing the interacting effects of disturbance regime and winter snow depth on plant emergence, growth, and reproductive effort in a restored tallgrass prairie. The “Treatments.csv” file includes details of the experimental design. The design includes two snow manipulation treatments (ambient or reduced snow) nested within one of three disturbance...
Data Release - Geologic Map geodatabase of the valley corridor of the 59-mile reach of the Missouri National Recreational River, South Dakota, Nebraska, and Iowa: Gavins Point Dam to North Sioux City Data Release - Geologic Map geodatabase of the valley corridor of the 59-mile reach of the Missouri National Recreational River, South Dakota, Nebraska, and Iowa: Gavins Point Dam to North Sioux City
This geologic map area of 5,430 km2 spans a reach of the lower Missouri River valley and adjoining uplands for about 100 kilometers east of Gavins Point Dam, the easternmost mainstem dam on the Missouri River. Understanding the surficial geologic history of the valley is relevant to natural resource management of the Missouri National Recreational River and is foundational to improved
Fuels Data for the 2000 Highland Creek Fire and 2017 Legion Lake Fire in Blacks Hills, SD, Collected in 2025 Fuels Data for the 2000 Highland Creek Fire and 2017 Legion Lake Fire in Blacks Hills, SD, Collected in 2025
Eleven pre-established plots within the 2000 Highland Creek Fire perimeter were revisited in 2025 with the purpose of characterizing long-term vegetation recovery as well as present-day fuel loads and forest structure. These research plots were originally established in Wind Cave National Park to assess burn severity using the Composite Burn Index. Additionally, 28 plots established in...
Geochemical and hydrologic data supporting assessment of a low-temperature geothermal system in Steamboat Springs, Colorado Geochemical and hydrologic data supporting assessment of a low-temperature geothermal system in Steamboat Springs, Colorado
Geothermal springs may be connected to both shallow and deep groundwater sources, and identification of variable spring sources may assist with resource management of geothermal systems. Numerous geothermal springs exist near the Yampa River in Steamboat Springs, Colorado and local water and land management agencies could benefit from information on the sources of these springs. This...
Input and Output files from the Zonebudget program used with MODFLOW models to compute regional groundwater budgets for the Virginia Coastal Plain aquifer system Input and Output files from the Zonebudget program used with MODFLOW models to compute regional groundwater budgets for the Virginia Coastal Plain aquifer system
This data release contains results from annual water budgets computed for two groundwater-flow models of the Virginia Coastal Plain published by the Virginia Department of Environmental Quality (Virginia Department of Environmental Quality, 2020, 2024a and 2024b). Both models simulated historical withdrawals from approximately 1900 to 2023 and projected withdrawal conditions to 2073...
Historical (1900s-1940s) and present-day (2003 – 2023) spring Chinook salmon (Oncorhynchus tshawytscha) spawning distribution in the Willamette River Basin, Oregon Historical (1900s-1940s) and present-day (2003 – 2023) spring Chinook salmon (Oncorhynchus tshawytscha) spawning distribution in the Willamette River Basin, Oregon
Spawning distribution maps for Upper Willamette River (UWR) spring Chinook salmon were created for the historical period (approximately 1910-1940), and for the present-day period (2003-2023). These maps were created as a tool to visualize generalized, reach-scale patterns of spawning distribution before and after the construction of high-head dams and other large-scale anthropogenic...
PIT tagging and detection of Chinook salmon (Oncorhynchus tshawytscha) in cold water refuges of the Klamath River PIT tagging and detection of Chinook salmon (Oncorhynchus tshawytscha) in cold water refuges of the Klamath River
We conducted a pilot study to evaluate the extent of cold water refuge use by juvenile outmigrating fall-run Chinook salmon (Oncorhynchus tshawytscha) in relation to managed water flows in the Klamath River. Juvenile fall-run Chinook salmon were captured and implanted with passive integrated transponder (PIT) tags and subsequently detected by submersible antennas that were strategically...
Model output and code for a long short-term memory model forecasting streamflow drought across the Conterminous United States by focusing on percentiles below 50 percent Model output and code for a long short-term memory model forecasting streamflow drought across the Conterminous United States by focusing on percentiles below 50 percent
Machine learning (ML) models were used to forecast streamflow drought from 1 to 13 weeks into the future at more than 3,000 streamgage locations across the conterminous United States. Long short-term memory [LSTM] neural network models were used to predict weekly streamflow percentiles with independent models for each forecast horizon. In this data release we specifically include an LSTM...
Aquaculture and irrigation water-use model (AIWUM) version 1.1 estimates and related datasets for the Mississippi Alluvial Plain, 2020–2023 Aquaculture and irrigation water-use model (AIWUM) version 1.1 estimates and related datasets for the Mississippi Alluvial Plain, 2020–2023
This data release contains monthly and annual water-use estimates from the Aquaculture and Irrigation Water-Use Model (AIWUM) version 1.1 for the Mississippi Alluvial Plain (MAP) from 2020 to 2023.

Estimates of plant water use needs for Tres Rios wetland and riparian corridor based on Landsat greenness and evapotranspiration time series from 2013-2024 Estimates of plant water use needs for Tres Rios wetland and riparian corridor based on Landsat greenness and evapotranspiration time series from 2013-2024
These spatial and tabular data were compiled to have a decade-long record of the water usage in the riparian corridor and the wetlands near Phoenix, Arizona called the Tres Rios area to observe the effect of riparian and wetland health as characterized by vegetation greenness and its water use or evapotranspiration. The objective of our study was to quantify evapotranspiration (in...
