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.

grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.2.0 grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.2.0
Greater sage-grouse (Centrocercus urophasianus; hereafter referred to as sage-grouse) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the West (Hanser & Knick, 2011; Rowland et al., 2006). They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great...
Analyses of Select Organic and Inorganic Data Collected from Lysimeters Installed at the Bemidji Crude Oil Spill Site, Minnesota, 2018, 2019, 2021 Analyses of Select Organic and Inorganic Data Collected from Lysimeters Installed at the Bemidji Crude Oil Spill Site, Minnesota, 2018, 2019, 2021
The U.S. Geological Survey (USGS) collected porewater samples from nine suction lysimeters in 2018, 2019, and 2021 for analysis of organic and inorganic constituents from the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, MN. In August of 1979, approximately 1,700,000 L (liters), or 10,700 barrels, of crude oil spilled onto a glacial outwash aquifer...
PAAD: The Planetary Aeolian Analog Database PAAD: The Planetary Aeolian Analog Database
The Terrestrial Analogs Data Portal (TADP; https://tadp.astrogeology.usgs.gov/) has been established as a repository and data discovery portal which leverages USGS ScienceBase, a trusted long-term digital repository that provides access to all USGS data services. Creation of the TADP service is in response to a number of NASA-generated reports identifying the need for a permanent...
Modeling the Effects of Interior Headland Restoration on Estuarine Sediment Transport Processes in a Marine-Dominant Estuary: Delft3D Model Output Modeling the Effects of Interior Headland Restoration on Estuarine Sediment Transport Processes in a Marine-Dominant Estuary: Delft3D Model Output
The effects of interior headland restoration on estuarine sediment transport processes are assessed through process-based numerical modeling. Three proposed interior headland restoration scenarios in the Grand Bay estuary (Mississippi/Alabama) are modeled using Delft3D (developed by Deltares) to understand impacts on suspended sediment concentrations, bed level morphology and sediment...
USGS Gulf Coast Geologic Energy Assessments and Research Project-Upper Jurassic Smackover Formation Continuous Resources: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS Gulf Coast Geologic Energy Assessments and Research Project-Upper Jurassic Smackover Formation Continuous Resources: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered continuous oil and gas resources in the Smackover formation in the U.S. Gulf Coast. 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 within the context of...
Geologic map of the Wichmann CA region of the Moon, Lunar Orbiter Site III P-11, Oceanus Procellarum including Apollo landing sites 4 and 4R Geologic map of the Wichmann CA region of the Moon, Lunar Orbiter Site III P-11, Oceanus Procellarum including Apollo landing sites 4 and 4R
This map shows the geology in and around two potential early Apollo landing sites in the equatorial belt. The Wichmann CA region is in the Oceanus Procellarum, south of the equator, approximately 320 km south of the crater Kepler. It is covered by mare material with numerous ridges, low domes, craters, and crater clusters. Relatively few of the craters are larger than 200 m across. Terra...
