Data Release for Laboratory and field comparisons of TFM bar formulations used to treat small streams for larval sea lamprey Data Release for Laboratory and field comparisons of TFM bar formulations used to treat small streams for larval sea lamprey
The dataset was generated to verify the suitability of the new TFM bar formulation for wide-scale use in the Sea Lamprey Control Program (SLCP). Dataset includes TFM concentrations of three streams (each used twice) where randomized experimental applications of new and old TFM bar formulation dissolution trials were conducted, TFM concentrations of 12 laboratory flume experimental...
Data release for Late glacial-Younger Dryas climate in interior Alaska as inferred from the isotope values of land snail shells Data release for Late glacial-Younger Dryas climate in interior Alaska as inferred from the isotope values of land snail shells
The isotopic values of fossil snail shells can be important archives of past climate. Here we present the first carbon (δ13C) and oxygen (δ18O) isotope values of radiocarbon-dated and live-collected snails in interior Alaska to explore changes in vegetation and humidity through the late glacial period (14-11.7 ka). Snail shell δ13C values were relatively consistent through the late...
Data Release for Lock 19 Underwater Acoustic Deterrent System (UADS) Study: Interim Project Update Data Release for Lock 19 Underwater Acoustic Deterrent System (UADS) Study: Interim Project Update
The Underwater Acoustic Deterrent System is an experimental deterrent that utilizes underwater sounds to deter invasive carps. An experimental deployment and evaluation of a UADS is currently being conducted at Lock 19 on the Mississippi River, near Keokuk, Iowa. This dataset includes information derived from two telemetry arrays (i.e., 307 kHz HTI and 69 kHz VEMCO) deployed at and...
Data Release for Luminescence: Butler Cave, Burnsville Cove, Bath and Highland Counties, VA Data Release for Luminescence: Butler Cave, Burnsville Cove, Bath and Highland Counties, VA
Burnsville Cove in Bath and Highland Counties (Virginia, USA) is a karst region in the Valley and Ridge Province of the Appalachian Mountains. The region contains many caves in Silurian to Devonian limestone, and is well suited for examining geologic controls on cave location and cave passage morphology. In Burnsville Cove, many caves are located preferentially near the axes of synclines...
Data Release for Luminescence: Construction and modification of debris-flow alluvial fans as captured in the geomorphic and sedimentary record: examples from the western Sangre de Cristo Mountains, south-central Colorado Data Release for Luminescence: Construction and modification of debris-flow alluvial fans as captured in the geomorphic and sedimentary record: examples from the western Sangre de Cristo Mountains, south-central Colorado
The following report summarizes the dating results from the San Luis Valley-Pioneer Fan 2017-2019 dating project. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be...
Data Release for Luminescence: Plio-Pleistocene Hydrology and Marine Isotope Stage (MIS) 4 Deep Springs Lake, Western Great Basin, Inyo County, California Data Release for Luminescence: Plio-Pleistocene Hydrology and Marine Isotope Stage (MIS) 4 Deep Springs Lake, Western Great Basin, Inyo County, California
Deep Springs Valley (DSV) is a hydrologically isolated valley between the White (north and west) and Inyo (south and east) Mountains that is commonly excluded from regional paleohydrologic and paleoclimate studies. Previous studies showed that uplift of Deep Springs ridge (informal name) by the Deep Springs fault defeated streams crossing DSV and hydrologically isolating the valley...
Data Release for Luminescence: Surficial Mapping of the Central Panamint Valley, Inyo County, California Data Release for Luminescence: Surficial Mapping of the Central Panamint Valley, Inyo County, California
Several historic, multi-fault ruptures in the Eastern California Shear Zone (ECSZ) reinforce the need to understand how this rupture style contributes to seismic hazard in complex and diffuse fault zones. Several historic earthquakes in the ECSZ, the 1992 Landers, the 1999 Hector Mine, and the 2019 Ridgecrest rupture sequence, involved complex and multi-fault rupture. However...
Data Release for Multimodal Invasive Carp Deterrent Study at Barkley Lock and Dam: Status Update through 2022 Data Release for Multimodal Invasive Carp Deterrent Study at Barkley Lock and Dam: Status Update through 2022
The BioAcoustic Fish Fence (BAFF; Fish Guidance Systems Ltd.) is a multi-modal deterrent that utilizes a combination of lights, sound, and bubbles to guide fish away from a location. An experimental deployment of a BAFF is currently ongoing at Barkley Lock and Dam on the Cumberland River near Grand Rivers, KY. This dataset includes information derived from two telemetry arrays (i.e...
Data release for spatial and temporal analysis of geologically derived fault slip rates, Cucamonga Fault, California, USA Data release for spatial and temporal analysis of geologically derived fault slip rates, Cucamonga Fault, California, USA
This report summarizes the age-dating results from two alluvial fan surfaces (map units Qyf2 and Qyf3) that are broken by strands of the Cucamonga Fault, in southern California, at Day Canyon and Etiwanda Canyon. Within this report are detailed the methodology used to collect samples of rock and sediment, determine concentrations of cosmogenic beryllium-10 in purified quartz isolated...
Data Release for Testing ecosystem accounting in the United States: A case study for the Southeast - 2022 Updates (ver. 2.0, February 2023) Data Release for Testing ecosystem accounting in the United States: A case study for the Southeast - 2022 Updates (ver. 2.0, February 2023)
Ecosystems benefit people in many ways, but these contributions do not appear in traditional national or corporate accounts so are often left out of policy- and decision-making. Ecosystem accounts, as formalized by the System of Environmental-Economic Accounting Experimental Ecosystem Accounts (SEEA EEA), track the extent and condition of ecosystem assets and the flows of ecosystem...
Data release for the 3D petroleum systems model of the Williston Basin, USA Data release for the 3D petroleum systems model of the Williston Basin, USA
This data release contains data associated with the journal article "Modeling the maturation history of the stacked petroleum systems of the Williston Basin, USA". Collectively, the data release includes 13 child items and metadata files that provide detailed descriptions of the attributes, processing steps, and original data sources. There is also a data table, "Williston_Basin_Data...
Data release for the Geologic Map of the Denali Park Road Corridor, Denali National Park, Alaska Data release for the Geologic Map of the Denali Park Road Corridor, Denali National Park, Alaska
Denali National Park and Preserve (DENA), located in central Alaska, is home to iconic and dynamic landscapes surrounding the tallest mountain range in North America, the Alaska Range. DENA preserves over 6 million acres of wild land that provides opportunities for recreation, subsistence hunting and gathering, preservation of cultural resources, and scientific research. Despite its size...
