The San Juan River is a major water source for communities in the Four Corners region of the United States (parts of Colorado, Arizona, New Mexico, Utah) and is a vital source of water for the Navajo Nation. The Navajo Nation Environmental Protection Agency (NNEPA) periodically samples surface water on the Navajo Nation and has found that some elements exceed NNEPA surface water...

This dataset comprises high-resolution geotif files representing various aspects of the ʻākohekohe (Palmeria dolei) potential habitat on the Island of Hawaiʻi. It includes a habitat suitability map showing average suitability scores, a map of homogenous forested areas (HFAs) depicting clusters with consistent suitability scores, and a map of pixel-wise standard deviation across habitat...

This dataset consists of sample descriptions and radiocarbon age data from coastal environments on Montague Island, Alaska, analyzed at the National Ocean Sciences Accelerator Mass Spectrometry Facility.

These are scanned recordings from the Rangely earthquake control experiment that took place from 1969-1974 in the area surrounding Rangely, Colorado. Data were telemetered to Menlo Park, California, where they were recorded on develocorder films. Twelve stations with a total of fourteen channels were recorded and are available in this data set. Data were collected by the US Geological...

This data release contains information collected during surveys for chorus fogs (Pseudacris maculata), wood frogs (Lithobates sylvaticus) and tiger salamanders (Ambystoma mavortium) conducted in Rocky Mountain National Park (1986 – 2022) by the U.S. Geological Survey. Survey methods included visual encounter and aural surveys, and dip netting. Data collected between 1986 and 1994 focused...

In support of a preliminary analysis performed by New York State Department of Environmental Conservation (NYSDEC) that found elevated nutrient levels along selected reaches of the Mohawk River, one-dimensional, unsteady, hydraulic and water-quality models using HEC-RAS and HEC-RAS Nutrient Simulation Module I (version 5.0.3) were developed by the U.S. Geological Survey (USGS) for the...

This data release contains the methodology and results of three field experiments performed in 2024 and 2025 to better understand how predation impacts detection efficiency of acoustic tags. The first experiment was a static approach focusing on how different tag types, tag power, depth, distance to passive receivers, and predation would affect detection efficiency and utilized both...

The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand by delivering routine assessments of water supply and demand. A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface...

This dataset accompanies planned publication 'Paleogene mid-crustal intrusions in the Ruby Mountains Metamorphic Core Complex, northeastern Nevada' [IP-153033], to be published in Geosphere, as well as planned future publications in this region. The data encompass U-Pb zircon age and trace element data and whole-rock Pb, Sr, and Nd isotopic data from igneous and metamorphic rocks...

This dataset contains taxonomic information, counts, and lengths of macroinvertebrates collected from rivers in northwest Alaska using drift and kick nets during summer and fall 2015-2019.

These data are in three tables each reporting estimated iron mineralization within stream reaches from three arctic rivers in northwestern Alaska on select days between July-August, 1985-2022. The relative magnitude of iron mineralization was measured using a remotely sensed iron index calculated from available Level 2, Collection 2, Tier 1 Landsat Surface Reflectance products derived by...

Landsat Extended Acquisitions of the Poles (LEAP) imaging plan is a Landsat special request data collection program for Earth's polar regions that include Antarctica, Greenland, and Arctic sea ice geographies. The LEAP program includes Landsat 8 and Landsat 9 observatories that operationally acquire spaceborne images of all Earth's land surface and near-shore coastal environments. These...
