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...
(ORB II-13 (100)) Geologic map of the Maestlin G region of the moon, Lunar Orbiter site II P-13, Oceanus Procellarum, including Apollo landing site 5 (ORB II-13 (100)) Geologic map of the Maestlin G region of the moon, Lunar Orbiter site II P-13, Oceanus Procellarum, including Apollo landing site 5
This map shows the geology in and around potential early Apollo landing site 5 in the lunar equatorial belt. The Maestlin G region is in Oceanus Procellarum, about midway between the crater Kepler to the northeast and Flamsteed to the southwest. Terra materials occur only in the northeast corner of the region. Dark mare covers the remainder, and the entire region is crossed by rays from...
Geologic map of the Maskelyne DA region of the moon, Lunar Orbiter site II P-2, southeastern Mare Tranquillitatis including Apollo landing site l Geologic map of the Maskelyne DA region of the moon, Lunar Orbiter site II P-2, southeastern Mare Tranquillitatis including Apollo landing site l
This map shows the geology in and around potential early Apollo landing site 1 in the lunar equatorial belt. The Maskelyne DA region, at the southeastern edge of the Mare Tranquillitatis, is in the area transitional between mare and terra. Patches of typical terra material occur on northwest-trending ridges, and typical heavily cratered mare materials occurs only in the east-central part...
A comparison of pan trap and hand net bee collection methods at Badlands National Park, South Dakota, 2012 A comparison of pan trap and hand net bee collection methods at Badlands National Park, South Dakota, 2012
This data record includes bee species captured by pan trap or hand net in 1-hectare, mixed-grass prairie plots at Badlands National Park, South Dakota, in 2012.
Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity L-4-90-SC Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity L-4-90-SC
Multichannel seismic (MCS) data were collected by the U.S. Geological Survey (USGS) in 1990 in the California Continental Borderland (USGS field activity L490SC). In 2021, these data were reprocessed to improve accuracy and resolvability of geologic structures and fault systems of California's continental margin. MCS data were acquired to support the Southern California Earthquake...
Multichannel sparker and chirp seismic reflection data collected during USGS field activity 2018-658-FA between Cape Blanco and Cape Mendocino in October of 2018 Multichannel sparker and chirp seismic reflection data collected during USGS field activity 2018-658-FA between Cape Blanco and Cape Mendocino in October of 2018
This data release contains processed high-resolution multichannel sparker seismic-reflection (MCS) data and chirp sub-bottom data that were collected aboard Humboldt State University's R/V Coral Sea in October of 2018 on U.S. Geological Survey cruise 2018-658-FA on the shelf and slope between Cape Blanco, Oregon, and Cape Mendocino, California. MCS data were collected to characterize...
U.S. Geological Survey simulations of 3D-hydrodynamics in Delaware Bay (2016, 2018, 2021) to improve understanding of the mechanisms driving salinity intrusion U.S. Geological Survey simulations of 3D-hydrodynamics in Delaware Bay (2016, 2018, 2021) to improve understanding of the mechanisms driving salinity intrusion
The Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST Warner and others, 2019; Warner and others, 2010) model was used to simulate three-dimensional hydrodynamics and waves to study salinity intrusion in the Delaware Bay estuary for 2016, 2018, 2021. Salinity intrusion in coastal systems is due in part to extreme events like drought or low-pressure storms and longer-term sea level...
Mountain Plover population and habitat assessments in Texas, 2019–2020 Mountain Plover population and habitat assessments in Texas, 2019–2020
We conducted population and habitat assessments for Mountain Plovers in Texas during winters of 2019 and 2020. We used roadside surveys and distance-sampling to estimate bird density and calculate population totals for the study area, which included parts of five ecoregions (Chihuahuan Deserts, High Plains, Central Great Plains, Southern Texas Plains, Texas Blackland Prairies, and...
