This toolbox was developed for use on mine waste sites in the state of Alaska. Many of these are placer mining sites, with small waste piles spread along a stream bed. The tool to calculate mine waste volume lets the user select between two different methods: surface difference and height estimation. The surface difference method was designed to estimate the volume of the stream bed...

lasertramdb (laser time resolved analysis module dashboard) is a tool for processing laser ablation icp-ms data from raw counts per second into chemical concentrations. Built using PyQT it is a graphical user interface that gives the user significant control over which portion of the signal is used in calculating final concentrations, ultimately allowing them to be more accurate. All...

This software release contains three R scripts that comprise an RShiny App to simulate scenarios and evaluate the optimal decision to move egg masses. The user is able to specify the size and number of egg masses in the donor and recipient pools as well as the number of recipient pools. The app will then display the number of metamorphs gained by moving the selected number of egg masses...

This code is associated with Gerber et al. manuscript titled, "Monitoring wolverine (Gulo gulo) distribution across the western United States for regional and national assessment", authored by members of the Western Association of the Fish and Wildlife Agencies (WAFWA) Forest Carnivore Subcommittee

Pysochron 2 is an open source 26Al/10Be burial isochron calculator, available for download in both .exe and .py formats. Like the original Pysochron, it uses orthogonal distance regression to fit isochron lines to measured concentrations of 26Al and 10Be and accounts for uncertainty using a Monte Carlo framework. The final output is a .pdf that contains the burial isochron diagram along...

This project contains scripts used to examine trends in historical sub-daily and daily rainfall in the State of Florida over the period 1990–2022. This project is a collaborative effort between the U.S. Geological Survey and South Florida Water Management District.

This repository contains the code used determine the effects of a carbon dioxide mat on zebra mussels. The supporting data has been released ass a USGS data release: Meulemans, M.J., Waller, D.L., Wise, J.K., Severson, T.J., Barbour, M.T., and Morris, B.E., 2026, Evaluation of benthic barrier layers/tarps for open water control of invasive mussels in 2024 in Loon Lake, Benzie Co...

Projected streamflow statistics have broad potential utility in evaluating future conditions of habitat quality for imperiled species. Future daily streamflow simulations are available via the Precipitation-Runoff Modeling System (PRMS) application of the USGS National Hydrological Model (NHM) for the conterminous United States (CONUS), but there remain barriers to user accessibility and

The Playback and Recording Device (PRD) is a low‑cost, field‑ready microcontroller platform designed for ecological monitoring, sensor integration, and automated data collection. This repository contains the firmware used in field deployments, audio cue files used for playback experiments, and documentation intended to ensure full reproducibility in accordance with HardwareX open...

During major storms or other short-term flood events, the USGS collects streamflow and additional data (including storm tide, wave height, high-water marks, and additional sensor deployments) to aid in documenting flood events. The USGS Flood Event Viewer provides convenient, map-based access to downloadable event-based data using individualized URLs for each storm. FEV leverages React...

This repository contains code to run the Alligator Production Suitability Index (APSI), a Joint Ecosystem Modeling (JEM) hosted model developed by the National Park Service. The model has been refactored in R from Java to facilitate further model development, updates, and collaboration with Everglades partners. The R version has been modified slightly from the original Java version to...

An R package for modeling health effects of environmental exposures, with a primary focus on groundwater contaminants. Based on epidemiological studies and existing concentration models.
