Data loggers were part a study beginning in 2017, with data available through 2019 for most locations. The spatial data layer contains site locations, geographic information, data summaries, mean August stream temperatures...
OFR 2021-1008 MODEL ARCHIVE: Soil-Water-Balance model developed to simulate net infiltration and irrigation water use for the Mississippi Embayment Regional Aquifer System, 1915 to 2018 OFR 2021-1008 MODEL ARCHIVE: Soil-Water-Balance model developed to simulate net infiltration and irrigation water use for the Mississippi Embayment Regional Aquifer System, 1915 to 2018
This model archive makes available the calibrated Soil-Water-Balance (SWB) model used to simulate potential recharge for the Mississippi Alluvial Aquifer for 1915 to 2018. The model was calibrated using monthly values of evapotranspiration and annual values of runoff and recharge for 19 drainage basins selected from within or nearby the Mississippi Alluvial Aquifer system. The calibrated...
Nutrient balances, river loads, and a counterfactual analysis to determine drivers of Mississippi River nitrogen and phosphorus loads between 1975 and 2017 Nutrient balances, river loads, and a counterfactual analysis to determine drivers of Mississippi River nitrogen and phosphorus loads between 1975 and 2017
This data release includes data processing scripts, data products, and associated metadata for a study investigating trends in Mississippi River (MR) nitrogen and phosphorus loads to the Gulf of Mexico. This data release consists of three main components: 1) Nitrogen and phosphorus balances, which account for major nutrient inputs (fertilizer, manure, waste water treatment facility...
occStan: Occupancy models with RStan occStan: Occupancy models with RStan
occStan is an R package (R Core Team 2021) providing a collection of occpuancy Bayesian models written in the Stan language as called through RStan (Stan Development Team 2021). The package is a USGS software software release. The purpose of the package is to document these models for use in USGS projects and allow easy discrimination. The package assumes the user is familiar with R and...
Body condition scores and foaling outcomes in 2021 for 18 mares at Sulphur herd management area, Utah treated with gonadotropin releasing hormone Body condition scores and foaling outcomes in 2021 for 18 mares at Sulphur herd management area, Utah treated with gonadotropin releasing hormone
These data present outcomes for monitoring of 18 mares at Sulphur herd management area, Utah. Data include Henneke body condition scores (BCS) and foaling success, measured by visual observations of mares during the 2021 breeding season (April to September 2021) to determine if mares had a foal at foot. Mares were treated with gonadotropin releasing hormone vaccine on September 2, 2020...
Specimen observation data for Najas marina L. from 1863 to 2020 Specimen observation data for Najas marina L. from 1863 to 2020
The North American distribution of Najas marina L. from 1863 to 2020 is presented in this dataset. Fields provided include georeferenced coordinates, dates of collections, collectors, and source herbaria. Data are housed in the U.S. Geological Survey's Nonindigenous Aquatic Species Database (nas.er.usgs.gov).
Estimated equivalent population using groundwater for public supply domestic use in the conterminous U.S. 2010, hydrogeologic mapping units, and wells used (ver. 2.0, March 2023) Estimated equivalent population using groundwater for public supply domestic use in the conterminous U.S. 2010, hydrogeologic mapping units, and wells used (ver. 2.0, March 2023)
These datasets map the estimated population using public supply drinking water (both groundwater and surface water) using two methods: the census enhanced method (CEM) evenly distributes the population across populated census blocks, and the urban land-use enhanced method (ULUEM) distributes the population only to certain urban land use designations. (See the six Estimated equivalent...
Data on grasshopper composition in the Thunder Basin National Grassland, Wyoming, USA Data on grasshopper composition in the Thunder Basin National Grassland, Wyoming, USA
Grasshopper biomass and species-level diversity was recorded at locations on and off prairie dog colonies in the Thunder Basin National Grassland, Wyoming, USA. Data were collected in order to record the association between grasshopper communities and prairie dog colonies.
Flood inundation map geospatial datasets for Lake Ontario, New York Flood inundation map geospatial datasets for Lake Ontario, New York
Static flood inundation boundary extents were created along the entire shoreline of Lake Ontario in Cayuga, Jefferson, Monroe, Niagara, Orleans, Oswego, and Wayne Counties in New York by using recently acquired (2007, 2010, 2014, and 2017) light detection and ranging (lidar) data. The flood inundation maps, accessible through the USGS Flood Inundation Mapping Program website at https:/...
Dissolved oxygen concentrations, light penetration, and temperature along the water-depth profile of wetlands P1 and P8 of the Cottonwood Lake Study area in North Dakota, USA, 2019 Dissolved oxygen concentrations, light penetration, and temperature along the water-depth profile of wetlands P1 and P8 of the Cottonwood Lake Study area in North Dakota, USA, 2019
This data release presents data that were collected as part of a larger effort to assess factors that regulate metabolism in global lakes, via an international collaboration with the Global Lake Ecological Observatory Network (GLEON). From May to August 2019, dissolved oxygen and light penetration were measured throughout the water-depth profile of two small inland wetlands at Cottonwood...
Presence and cover of exotic annual and perennial grass species during five years post-fire on the Soda Wildfire Presence and cover of exotic annual and perennial grass species during five years post-fire on the Soda Wildfire
Data includes cover and presence (within microsites and 13 m radius plots) of three exotic annual grass, Bromus tectorum, Taeniatherum caput-medusae, and Ventenata dubia and presence (within microsites) of four perennial bunchgrass species (Agropyron cristatum, Pseudoroegneria spicata, Poa secunda, Elymus elymoides) within the first five years after the 2015 Soda wildfire. Additional...
Tidal Datums, Tidal Range, and Nuisance Flooding Levels for Chesapeake Bay and Delaware Bay Tidal Datums, Tidal Range, and Nuisance Flooding Levels for Chesapeake Bay and Delaware Bay
This U.S. Geological Survey data release provides data on spatial variations in tidal datums, tidal range, and nuisance flooding in Chesapeake Bay and Delaware Bay. Tidal datums are standard elevations that are defined based on average tidal water levels. Datums are used as references to measure local water levels and to delineate regions in coastal environments. Nuisance flooding refers...
