The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined...
Long-term gas and heat emissions measurements, Norris Geyser Basin, Yellowstone National Park Long-term gas and heat emissions measurements, Norris Geyser Basin, Yellowstone National Park
We installed an eddy covariance station on July 10, 2018 at Bison Flat, an acid-sulfate, vapor-dominated area (0.04-km2) in Norris Geyser Basin, Yellowstone National Park, WY to monitor variations in hydrothermal gas and heat emissions. Since then, this station has measured CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, and wind speed and direction on a half...
Site and Survey Data for Dixie Valley Toads in Churchill County, Nevada, 2019 Site and Survey Data for Dixie Valley Toads in Churchill County, Nevada, 2019
These data include site- and survey-specific information for occupancy surveys of Dixie Valley Toads (Anaxyrus williamsi) collected in the Dixie Valley, Churchill County, Nevada, in May 2019. The data include both multiple surveys of the same sites and time-to-detection information to quantify detection probabilities and account for imperfect detection in assessments of Dixie Valley Toad...

The USGS Gulf Coast Source Rock Database (GCSRD) is an online repository for all publicly available source rock data (outcrop and subsurface) from the states of Florida, Georgia, Alabama, Mississippi, Louisiana, Arkansas, and Texas. "Source rock data" are defined in this context as data that include any of the following measured or calculated parameters: -total organic carbon (TOC),...
Hawaii Island tree response to koa moth outbreak, 2013-2014 Hawaii Island tree response to koa moth outbreak, 2013-2014
This data release includes metadata and tabular data that document the response of koa (Acacia koa) trees to defoliation by the koa moth (Scotorythra paludicola) during 2013-2014 at Hakalau Forest National Wildlife Refuge. Data were collected on 55 plots at 4 sites representing 2 habitat types with either high or low koa densities. Ohia (Metrosideros polymorpha) trees dominated habitats...
