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.

Digital elevation model (DEM) and digital surface model (DSM) data for the Colorado River corridor in Grand Canyon National Park and Glen Canyon National Recreation Area (2002, 2009, 2013 and 2021), including accuracy assessment data Digital elevation model (DEM) and digital surface model (DSM) data for the Colorado River corridor in Grand Canyon National Park and Glen Canyon National Recreation Area (2002, 2009, 2013 and 2021), including accuracy assessment data
These datasets consist of four, 1-meter spatial resolution digital surface models (DSMs) that were generated to orthorectify airborne multispectral imagery acquired in 2002, 2009, 2013, and 2021 for the Colorado River in Grand Canyon in Arizona, USA. These datasets also consist of a 1-meter spatial resolution digital elevation model (DEM) that was generated from the 2021 DSM. The DSMs...
Altitudes of well measuring points surveyed during 2023–24, Hālawa area, O‘ahu, Hawai‘i Altitudes of well measuring points surveyed during 2023–24, Hālawa area, O‘ahu, Hawai‘i
This data release contains a comma-delimited file of 71 well measuring-point altitudes for monitored wells in the Hālawa area, O‘ahu, Hawai‘i. The measuring-point altitude of a monitoring well is needed to determine the groundwater level in the well relative to a datum such as local mean sea level. A well measuring point is typically located at the top of the well casing. By surveying...
Warming Tolerances for 34 Species of Anurans Native to the Southeast United States Warming Tolerances for 34 Species of Anurans Native to the Southeast United States
Identifying how close species are to their current upper thermal limits estimates species sensitivity to climate change (or the species ability to persist in place without changing). Process-based models like the NicheMapR mechanistic niche model (Kearney et al. 2019; https://doi.org/10.1111/ecog.04680) use a mass-balance approach to translate microclimate estimates into individual...
Geochemical data for the relationship between whole rock S/Fe and degree of organic sulfurization in the Eagle Ford Group Geochemical data for the relationship between whole rock S/Fe and degree of organic sulfurization in the Eagle Ford Group
Geochemical data were generated from multiple thermally immature drill cores of the Eagle Ford Group across Texas. This data set accompanies a journal article that shows the relationship between whole rock S/Fe and degree of organic sulfurization across the thermally immature Eagle Ford in Texas. The data include LECO total carbon and total organic carbon, programmed pyrolysis, whole...
Fish communities in streams of the Maryland-Washington, DC-Virginia developed Piedmont, 2024 Fish communities in streams of the Maryland-Washington, DC-Virginia developed Piedmont, 2024
From May 27 to June 21, 2024, a Virginia Tech team of 5 sampled the fish community in 30 streams spanning a gradient of the developed landscape, including Potomac River, Rappahannock River, and upper Chesapeake Bay tributaries of Maryland, Washington, D.C., and Virginia, USA. These fish surveys were part of a larger stream-health study including other teams who surveyed geomorphology...
Data to fit habitat suitability models at different invasion stages and their results to evaluate model decisions Data to fit habitat suitability models at different invasion stages and their results to evaluate model decisions
This is a dataset containing the input and output data used in the analysis of best practices of invasive plant species distribution modeling (Young et al. 2024). We developed habitat suitability models for 13 invasive plant species at a variety of geographic ranges and different invasion stages and modeling strategies to assess the impact of predictor quality, thinning resolution, and...
