The USGS Wyoming-Montana Water Science Center (WY–MT WSC) completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 66.7-, 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for...

-R code to create and fit dynamic occupancy models to Dixie Valley Toad survey data in JAGS and produce useful summaries of model results. This script will perform the Gibbs Variable Selection (GVS) using the initial set of environmental covariates, and then fit the "final" model using only important environmental covariates. The dynamic occupancy model is adapted from the model...

In 2021, the U.S. Geological Survey (USGS) Mercury Research Laboratory (MRL) conducted a large-scale assessment of mercury (Hg) concentrations and Hg stable isotope values in tributaries of Lake Superior in order to define the sources and amounts of Hg entering the lake. Water samples were collected monthly from 18 tributaries in the United States from April through October in 2021 and...

Many aspects of recurring plant developmental events – vegetation phenology – are measured by remote sensing. By consistently measuring the timing and magnitude of the growing season, it is possible to study the complex relationships among drivers of the seasonal cycle of vegetation, including legacy conditions. We studied the role of current and legacy climate, and contextual factors on...

These data include geochemical analyses of rock, mine waste, sediment, soil, and water samples collected from the Hajigak iron deposit, Bamyan and Wardak Provinces, Afghanistan in 2019.

A model of the lower seismogenic depth distribution of earthquakes in the western United States was developed to support models for seismic hazard assessment that will be included in the 2023 USGS National Seismic Hazard Model. This data release presents a recalibration using the hypocentral depths of events M>1 from the Advanced National Seismic System Comprehensive Earthquake Catalog...

Environmental DNA results for March 2022 smallmouth bass surveillance in the Gardner River, Montana

This dataset contains surface dive times, defined as 0-2 m in the water column, for three species of sea turtles (Kemp's ridleys, loggerheads, and green turtles) tracked via satellite telemetry in the Gulf of Mexico during periods within 2010-2019. It contains information on turtle species, location, proportion of time in "surface" bins, region of the Gulf of Mexico, corresponding...

This repository contains the source code for the oaftools package. The package creates visual tools to study aftershock behavior and the performance of the Operational Aftershock Forecasting system. The visual tools are: A global map, rendered by Leaflet to show the distribution of earthquakes with forecasts A local map, rendered by Leaflet to show the aftershock sequence and the...

These data were compiled for the National Park Service and Upper Colorado River Endangered Fish Recovery Program. Objective(s) of our study were to resurvey previously established cross sections on the Yampa and Little Snake rivers in the Deerlodge Park area to document changes in channel width, depth, and cross-sectional area. A secondary purpose of this study was to document the...

These data were compiled to investigate the demographic and phylogeographic of Carex specuicola. Objectives of our study were to understand the demographic and dispersal history of Carex specuicola across hanging gardens, the hybridization history between Carex specuicola and Carex utahensis, and the population structure of Carex specuicola across its distribution. The data release...

Microsatellite genotypes for American black bears collected by Gould et al. 2002 and used to assess the genetic structure of American black bear populations in the American Southwest and northern Mexico. Genotypes are for Ursus americanus individuals.
