Data Release for the 2023 U.S. 50-State National Seismic Hazard Model - Overview Data Release for the 2023 U.S. 50-State National Seismic Hazard Model - Overview
This data release contains data sets associated with the 2023 50-State National Seismic Hazard Model Update. The 2023 50-State National Seimsic Hazard Model (NSHM) Update includes an update to the NSHMs for the conterminous U.S (CONUS, last updated in 2018), Alaska (AK, last updated in 2007), and Hawaii (last updated in 2001). Data sets include inputs like seismicity catalogs used as...
Data Release for the The 2023 Alaska National Seismic Hazard Model Data Release for the The 2023 Alaska National Seismic Hazard Model
The U.S. National Seismic Hazard Model (NSHM) for the state of Alaska was updated in 2023 as part of the 50-state NSHM update. The new model incorporates more than 15 years of additional science since the release of the previous model in 2007 and has been reviewed by a six-member review panel and a supplementary eight-member team of ground motion model developers. This time-independent
Data release for toxicity of Antimycin A incorporated management bait for grass carp Data release for toxicity of Antimycin A incorporated management bait for grass carp
The goal of this study was to develop and examine whether a management bait that can be used for selective control of grass carp. Our objectives were to 1) quantify the water-based 24-h LC50 of Antimycin-A for grass carp and rainbow trout, 2) quantify the 96-h LD50 of orally administered Antimycin-A laden bait for grass carp and rainbow trout, 3) quantify the leaching rate of Antimycin-A...
Data Release of Final Report to Bureau of Reclamation: Case Study Using KINEROS Model to Assess Potential Hydrologic and Geomorphic Impacts of Installing Gabions in a Developing Subwatershed near Buckeye, Arizona, USA Data Release of Final Report to Bureau of Reclamation: Case Study Using KINEROS Model to Assess Potential Hydrologic and Geomorphic Impacts of Installing Gabions in a Developing Subwatershed near Buckeye, Arizona, USA
This data release provides results from a watershed modelling effort to depict the use of natural infrastructure in dryland streams (NIDS), i.e., gabions, as a low-tech and low-cost, nature-based solution for increased water availability in the Buckeye area, west of the White Tank mountains and northwest of Phoenix, AZ, USA. Our goal was to identify impacts of current management and...
Data release of isotope geochemistry, mineral chemistry, and geochronology for a Proterozoic paragneiss sampled from drill core from North Dakota Data release of isotope geochemistry, mineral chemistry, and geochronology for a Proterozoic paragneiss sampled from drill core from North Dakota
This U.S. Geological Survey (USGS) data release provides whole rock isotope geochemistry, zircon hafnium isotope geochemistry, feldspar mineral chemistry, and zircon, monazite, and xenotime geochronology for a paragneiss sampled from a drill core from North Dakota. The sample was collected from the 9-11R E-M Larson well in order to constrain the depositional age, provenance, metamorphic...
Data release of monazite and xenotime geochronology for Proterozoic rocks in central Colorado and monazite and zircon geochronology and whole-rock isotope geochemistry fo a Proterozoic drill core sample from western Colorado Data release of monazite and xenotime geochronology for Proterozoic rocks in central Colorado and monazite and zircon geochronology and whole-rock isotope geochemistry fo a Proterozoic drill core sample from western Colorado
This U.S. Geological Survey (USGS) data release provides monazite and xenotime geochronology from Proterozoic rocks collected from outcrop in central Colorado and whole rock isotope geochemistry, and zircon and monazite geochronology from a Proterozoic rock sampled from a drill core from western Colorado. The drill core sample was collected from the 1 Paradox Valley injection core near...
Data release of zircon U-Pb geochronology and whole-rock isotope geochemistry for drill core samples from Montana, Nebraska, Nevada, and Wyoming Data release of zircon U-Pb geochronology and whole-rock isotope geochemistry for drill core samples from Montana, Nebraska, Nevada, and Wyoming
This U.S. Geological Survey (USGS) data release provides zircon U-Pb geochronology and whole rock isotope geochemistry for drill core samples from Montana, Nebraska, Nevada and Wyoming. The drill core samples were obtained from the USGS Core Research Center in Denver, Colorado. The samples were in order to constrain the age, provenance, metamorphic history, and geochemical character of...
Data Release: Bee and plant inventory data from four national parks in Maryland and Virginia, USA, 2021–2022 Data Release: Bee and plant inventory data from four national parks in Maryland and Virginia, USA, 2021–2022
This data release is for all native bee and plant records collected at four national parks in Maryland and Virginia, 2021 and 2022. The purpose of the study was to document the floral resources and native bees that depend on them within variously-managed park grasslands, with the goal of providing managers with information that will help them maximize pollinator habitat while...
Data release: early warning indicators for harmful algal bloom assessments in the Illinois River, 2013 - 2020 Data release: early warning indicators for harmful algal bloom assessments in the Illinois River, 2013 - 2020
Harmful algal blooms (HABs) have recently been observed in rivers, including the Illinois River in the Midwest United States. The Illinois River Basin has a history of eutrophication issues, primarily caused by the excessive loading of nitrogen and phosphorus from urban and agricultural sources. Recent events have seen the emergence of cyanobacterial harmful algal blooms in the area...
Data sets for: Status of Water Quality in Groundwater Resources Used for Drinking-Water Supply in the Southeastern San Joaquin Valley, 2013-2015 - California GAMA Priority Basin Project Data sets for: Status of Water Quality in Groundwater Resources Used for Drinking-Water Supply in the Southeastern San Joaquin Valley, 2013-2015 - California GAMA Priority Basin Project
This data release contains site information and potential explanatory factor data for 1,899 groundwater sites. These sites were used to assess groundwater quality in aquifers used for domestic and public drinking water supply in the southeastern San Joaquin Valley. The southeastern San Joaquin Valley (SESJV) study unit consists of five study areas whose boundaries are defined by the...
