The GIS shapefile "bison_locations" provides 132996 locations of 5 adult female bison marked with global positioning system (GPS) collars at Tallgrass Prairie National Preserve during February 2021 to November 2023. We provide locations computed at 15-min and 1-h intervals for individual bison and the date and time of acquisition for each location. Users are advised that ground...

This GIS shapefile, "density_contours," describes 1) a bison study area at Badlands National Park, South Dakota, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2015-2024. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the...

This data release includes laboratory analyses for biofilm and bed-sediment samples collected from streams in the Clark Fork Basin, spanning from Butte to near Missoula, Montana. Samples were collected by the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency as part of a long-term monitoring program. Biofilm samples were collected once at 19 sites...

The dataset includes .csv spreadsheets which provide whole rock geochemical data for the alkaline silicate rock and carbonatite rock samples for the Mountain Pass Intrusive Suite that were analyzed as part of this study, as well as whole rock Rb-Sr and Sm-Nd isotopic data for whole rock alkaline silicate samples. The .csv files containing this data are associated with individual data...

In unconsolidated glacial sediments and exhumed bedrock of Minnesota, USA, landslides may occur on low-relief steep slopes generated by post-glacial fluvial network development and drainage of glacial lakes. As part of an investigation to understand the link between various environmental variables, post-glacial landscape development, and a previously mapped landslide inventory, we...

Existing simulated groundwater head and water-budget output files from MODFLOW models for the Plymouth-Carver region (Masterson and others, 2009), the Hyannis Ponds Cape model (LeBlanc and others, 2019), and a SEAWAT model of lower Cape Cod (Masterson, 2004) were used in a new MODPATH version 6 (MP6) (Pollock, 2012) particle-tracking analyses. In the MODPATH6 analyses, endpoints...

This dataset provides time series for the ungaged watershed inflows and associated inflow points for the Lower Salinas Valley Hydrologic Models (SVHM), including the Salinas Valley Integrated Hydrologic Model (SVIHM) and the Salinas Valley Operational Model (SVOM). Monthly outflows from watersheds that do not have gages that surround the Salinas River Valley are used in the Lower Salinas...

This data release contains three variables from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System (NHM-PRMS) version 1.1 modeling application forced with CONUS404-BA (Markstrom and others, 2024) from January 1st, 1980 through September 25th, 2021 that are summarized to a twelve-digit hydrologic unit code for the spatial extent of the conterminous...

In 2015 the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) in cooperation with the Alaska Department of Fish and Game (ADFG) collected bathymetry and acoustic backscatter data offshore Cross Sound in southeast Alaska using an Reson 7111 multibeam echosounder mounded to the ADFG R/V Solstice. The survey was conducted to map the offshore expression of the...

One of the largest and most expensive restoration efforts in the world is occurring in the Everglades, a sub-tropical freshwater wetland system located in southern Florida. This unique ecosystem supports several endemic and endangered species, provides flood control for Florida’s large urban population, and provides water for both agriculture and drinking supply within the state. The...

This data release includes data and metadata documenting the removal of eggs from wild palila (Loxioides bailleui) nests to stimulate wild renesting while hatching the harvested eggs and rearing the chicks in captivity for later release to the wild. Some eggs were not harvested and were monitored in the wild for hatching and resulting progeny. The data provides details related to the...

4+ year old cisco (Coregonus artedi) pre-spawn and spawning/near-spawning behavioral data were collected and compiled at the Tunison Laboratory of Aquatic Science in Cortland, NY USA, between August-October 2021 and November-December 2021. Data are comprised of fish reactions in choice flume video data (attractance/avoidance). Cisco were exposed/not exposed to an imprinting chemical...
