Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Vegetation Composition and Management History Data (2015-2019) from Experimental Plots at Badlands NP, Wind Cave NP, and Scotts Bluff NM Used to Develop the ABAM Model
Plant species cover and richness data were collected in experimental plots at three sites: one at Badlands National Park (BADL), South Dakota, one at Scotts Bluff National Monument (SCBL), Nebraska, and one at Wind Cave National Park (WICA), South Dakota. At the Badlands and Scotts Bluff sites, data were collected in the summers of 2015 and 2017-2020 in 50 x 50-m plots with one of five treatments:
Penstemon grahamii genetic data from a dryland region of the western United States
These data were compiled to investigate the evolutionary history of Graham's beardtongue (Penstemon grahamii). Objective(s) of our study were to determine the evolutionary history of P. grahamii, including ancestral population sizes, the history of population divergences, and historical connectivity. In addition, we characterized population structure, genetic diversity summary statistics, and land
Structure from motion products associated with UAS flights in Sandwich, Massachusetts between January 2016 - September 2017
Low-altitude (80-100 meters above ground level) Unmanned Aircraft Systems (UAS) imagery of Town Neck Beach in Sandwich, Massachusetts, were used in a structure-from-motion (SfM) photogrammetry workflow to create high-resolution topographic datasets. Imagery was collected at close to low tide on twelve days to observe changes in beach and dune morphology. Ground control points (GCPs), which are tem
Blood Parasite Infection, Body Mass, and Survival Data from Emperor Geese (Anser canagicus), Yukon-Kuskokwim Delta, Alaska, 2006-2016
This dataset provides two tables of blood parasite infection data collected from Emperor Geese (Anser canagicus) on Yukon-Kuskokwim Delta, Alaska, 2006-2016. Three genera of blood parasites (Leucocytozoon, Haemoproteus, Plasmodium) were detected by molecular sequencing of a 479 bp fragment of the Cytochrome-b gene. The data provided in the tables are: 1) age, sex, mass, infection status, and NCBI
Potentially Resolvable National Hydrography Dataset Waterbodies and Flowlines from Landsat Images in the United States (excluding Alaska)
This data release presents two datasets including waterbodies (reservoirs, lakes, ponds, wetlands, etc.) and flowlines (stream reaches) from the high-resolution National Hydrography Dataset Plus (NHDPlus HR) that are potentially observable from Landsat images for the United States (excluding Alaska). To determine where National Hydrography Dataset Plus high resolution (NHDPlus HR; USGS 2019) featu
Data for Simulating the Effects of Air Temperature and Precipitation Changes on Streamflow and Water Temperature in the Meduxnekeag River Watershed, Maine
The U.S. Geological Survey (USGS), in cooperation with the Houlton Band of Maliseet Indians (HBMI), has developed tools to assess the effects climate change on hydrology and water temperatures in the Meduxnekeag River Watershed in Maine. A USGS Scientific Investigations Report (SIR) report documents tools and datasets developed by the USGS to evaluate how climate change will affect the hydrology a
Input and output data from streamflow and water-quality regression models used to characterize streamflow and water-quality conditions in the Upper Yampa River Basin, Colorado, from 1992-2018
This dataset includes input and output data from streamflow and water-quality regression models used to characterize streamflow and water-quality conditions in the Upper Yampa River Basin, Colorado from 1999-2018. All input data, including discrete and continuous streamflows and discrete concentrations of suspended sediment, Kjeldahl nitrogen, and total phosphorus, were compiled from the U.S. Geol
Dissolved-Selenium Concentrations and Loads in the Lower Gunnison River Basin, Colorado, as Part of the Selenium Management Program (ver. 3.0, August 2023)
The U.S. Geological Survey (USGS ), in cooperation with the Bureau of Reclamation, completed a review of dissolved selenium data collected from the Selenium Management Program network during each water year (WY) in the lower Gunnison River Basin, in western Colorado. The data tables include dissolved-selenium concentrations, selected streamflow data, and computed loads as well as dissolved seleniu
Sedimentological and geotechnical analyses of marine sediment cores from the New England Mud Patch
Variability in sediment properties with depth and the thickness of individual sedimentary layers are critical determinants of seabed acoustic response. The New England Mud Patch, located south of Cape Cod, is an unusual feature on the U.S. Continental Shelf in that it is composed of fine-grained sediment layers containing a relatively-homogeneous mix of sand, silt, and clay-sized particles bounded
Florida physiological and morphological data from wild and recently captive Python bivittatus 2018-2019
This dataset provides morphological and blood-derived physiological data from invasive Burmese pythons (Python bivittatus) captured in Florida. Data were collected on pythons at capture in the field and in varying lengths of time in captivity. Samples were collected immediately at handling (baseline) and 1 hour post-restraint. Physiological data include circulating corticosterone hormone levels, f
Maui Island Modeling Scenarios for the Management of Axis Deer 1959-2014
Our objectives were to examine the population history of axis deer on Maui, estimate observed population growth, and then use species-specific demographic parameters in a VORTEX population viability analysis to examine removal scenarios that would most effectively reduce the population. Only nine deer were introduced in 1959, but recent estimates of less than 10,000 deer suggest population growth
Lanai Island Spatial Prioritization of Native Plant Habitat and Hunting Areas, 2021
This data release includes data and metadata on all native plant species, native habitat, and hunting areas included in the spatial prioritization analyses. Broadly, recovery of threatened and endangered species requires specific management actions by natural resource managers at a fine scale. We used a systematic conservation planning framework to outline conservation goals across multiple land-u
