Projected peak instantaneous rate of green-up date and spring scale across Wyoming from 2000 to 2099 Projected peak instantaneous rate of green-up date and spring scale across Wyoming from 2000 to 2099
These data represent projections of peak instantaneous rate of green-up date (PIRGd) and spring scale across Wyoming from 2000-2099. Annual data is provided in gridded time series at approximately 4 km spatial resolution. Projections were generated by applying linear mixed models to contemporary remote sensing data, and applying model parameters to future climate projection data from the...
Estimated water surface elevations for selected monthly flow exceedance percentiles for Firesteel Creek upstream from Lake Mitchell in Davison County, South Dakota, 2021 Estimated water surface elevations for selected monthly flow exceedance percentiles for Firesteel Creek upstream from Lake Mitchell in Davison County, South Dakota, 2021
The City of Mitchell, South Dakota is exploring ways to improve water quality in Firesteel Creek, which flows into Lake Mitchell. One possible way is to construct a wetland on City-owned land in the Firesteel Creek floodplain above Lake Mitchell, allowing sediment deposition and nutrient uptake by aquatic vegetation in the constructed wetland. In order for a constructed wetland to be...
Field and laboratory data to determine lethal pesticide concentrations for control of invasive crayfish Field and laboratory data to determine lethal pesticide concentrations for control of invasive crayfish
Data were collected associated with the application of a pesticide to a stormwater retention pond and burrows to suppress or eradicate an invasive crayfish species, Procambarus clarkii, in support of high-priority research developing control methods to mitigate impacts of invasive crayfish within the Great Lakes Basin. Effectiveness of the treatment was accessed using an in-situ bioassay...
Black-tailed prairie dog capture data from plots treated and not treated with oral plague vaccine from 2013-2017 in Montana Black-tailed prairie dog capture data from plots treated and not treated with oral plague vaccine from 2013-2017 in Montana
Oral sylvatic plague vaccine baits (SPV) and placebo baits were distributed once annually from 2013-2016 on treated and non-treated paired plots from 2013-2016. Black-tailed prairie dogs (BTPD) were live-trapped and permanently marked with passive integrated transponders and ear tags on 4 pairs of plots each year from 2013-2017 to provide capture/recapture data for use in estimating BTPD...
Black-tailed prairie dog movement and bait uptake data from 2013-2017 in Montana Black-tailed prairie dog movement and bait uptake data from 2013-2017 in Montana
Oral sylvatic plague vaccine baits (SPV) and placebo baits, each containing Rhodamine B dye biomarker, were distributed once annually from 2013-2016 on treated and non-treated paired plots from 2013-2016. Black-tailed prairie dogs (BTPD) were live-trapped and permanently marked with passive integrated transponders and ear tags on 4 pairs of plots each year from 2013-2017 to provide...

This data package includes 3 child items with mapping data of polar bear den habitat on the Arctic Coastal Plain of Alaska. Child Item 1: "Data Used to Compare Photo-Interpreted and IfSAR-Derived Maps of Polar Bear Denning Habitat for the 1002 Area of the Arctic National Wildlife Refuge, Alaska, 2006-2016" Child Item 2: "Polar Bear Maternal Den Habitat on the Coastal Plain of Northern...
SEAWAT, MODFLOW-2000, and SHARP models used to simulate potential water-allocation changes, Cape May County, New Jersey SEAWAT, MODFLOW-2000, and SHARP models used to simulate potential water-allocation changes, Cape May County, New Jersey
Three existing groundwater flow models, using MODFLOW-2000, SEAWAT, and SHARP model codes, were used by the U.S. Geological Survey (USGS) to determine the effects of increased withdrawals, and shifts of withdrawals between 2 aquifers, on the limited water resources in the Cape May County, New Jersey. Saltwater intrusion and declining water levels have been a water-supply problem in Cape...
2020 Systemic Land Cover Data, Upper Mississippi River System (UMRS) 2020 Systemic Land Cover Data, Upper Mississippi River System (UMRS)
The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to...
Comparative Virulence of Spring Viremia of Carp Virus (SVCV) Genotypes in Two Koi Varieties Comparative Virulence of Spring Viremia of Carp Virus (SVCV) Genotypes in Two Koi Varieties
Spring viremia of carp virus (SVCV, species Carp sprivivirus), is considered one of the most lethal freshwater pathogens of cyprinid fish. Common carp Cyprinus carpio L. and koi C. carpio koi are the most susceptible host fish species. The virus was formally described in the 1960's after outbreaks occurred in carp species on the European continent, but there has been a global expansion...
CMIP5 MACAv2-METDATA Monthly Water Balance Model Projections 1950-2099 for the Contiguous United States CMIP5 MACAv2-METDATA Monthly Water Balance Model Projections 1950-2099 for the Contiguous United States
We apply a monthly water-balance model (MWBM) to simulate components of the water balance for the period 1950-2099 under RCP4.5 and RCP8.5 for the Contiguous United States. We use the statistically downscaled MACAv2-METDATA temperature and precipitation data from 20 General Circulation Models (GCMs) from the Climate Model Intercomparison Program Phase 5 (CMIP5) as input to the water...
Supporting data for analysis of general water-quality conditions, long-term trends, and network analysis at selected sites within the Missouri Ambient Water-Quality Monitoring Network, water years 1993–2017 Supporting data for analysis of general water-quality conditions, long-term trends, and network analysis at selected sites within the Missouri Ambient Water-Quality Monitoring Network, water years 1993–2017
The U.S. Geological Survey (USGS), in cooperation with the Missouri Department of Natural Resources (MDNR), collects data pertaining to the surface-water resources of Missouri. These data are collected as part of the Missouri Ambient Water-Quality Monitoring Network (AWQMN) and are stored and maintained by the USGS National Water Information System (NWIS) database.
