Reston Stable Isotope Lab Laboratory Information Management System (LIMS) for Lasers & Light Stable Isotopes
The Reston Stable Isotope Laboratory LIMS (Laboratory Information Management System) software suite is available for download: 1) LIMS for Lasers 2015 for off-axis and cavity ring-down laser absorption spectrometers, 2) LIMS Data Viewer, a companion utility that allows read-only access to LIMS for Lasers data, and 3) LIMS for Light Stable Isotopes for isotope-ratio mass spectrometers.
mapRandomForest---Monthly flow estimation in the Mississippi Alluvial Plain by means of Random Forest Modeling
The code included in this package, when combined with data retrieved from an associated ScienceBase archive, is designed to allow for reasonable monthly total and baseflow volumes to be estimated at arbitrary locations within the Mississippi Embayment as part of the Mississippi Alluvial Plain (MAP) Project. The resulting surface water volume estimates were used as inputs to associated groundwater
grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases
Greater sage-grouse (Centrocercus urophasianus) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the western United States. They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great Plains of the United States. Sage-grouse are one of the most closely monitor
Multi-grid Analysis of Point Stability Tool
Elevation-change datasets can also be used to identify stable and unstable areas of the seafloor. The Multi-grid Analysis of Point Stability (MAPS) program was created to automate this process. This program is used to locate persistent areas of user-defined seafloor stability and/or instability at common geographic locations from multiple elevation-change datasets (grids) representing different ti
MetaIPM
MetaIPM is a Python package (Python Software Foundation 2020) that models meta-population dynamics and continuous growth rates via an integral projection model (IPM) for species living in distinct habitat patches.
The package stems from a model that compares invasive carp population control strategies.
The package supports differing sex and any organisms living in distinct habitat patches.
gfail_lifelines
gfail_lifelines is a package for estimating lifeline impacts caused by earthquake-triggered ground failure. It currently contains one module, gfroads, that combines the USGS earthquake-triggered landslide model (the Nowicki Jessee et al. 2017 model) estimates of areal coverage with Open Street Map roads to estimate the probability of a given road segment being affected.
Stochastic Empirical Loading and Dilution Model (SELDM) software archive
The Stochastic Empirical Loading and Dilution Model (SELDM) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to transform complex scientific data into meaningful information about the risk of adverse effects of runoff on receiving waters, the potential need for mitigation measures,
North American Bat Monitoring Program: R Data Connection Package, (Version 1.0.1)
The North American Bat Monitoring Program: R Data Connection Package can be used to extract and upload data to the NABat Monitoring Program through the GQL API. This software is written as a wrapper around the NABat GQL API. Documentation for the database and API can be found at https://sciencebase.usgs.gov/. This code includes the ability to reformat NABat data, upload NABat data, create reports,
WildAgg: an R package to estimate and visualize wildlife aggregation data
This package is designed to estimate, summarize, and visualize wildlife aggregation metrics using location information like GPS collar data. The motivation for the development of this package began with two research efforts studying the aggregation and density of elk on the National Elk Refuge, Wyoming (Janousek et al.2021; and Graves et al. 2021). The primary goal of the WildAgg package is to pro
Bighorn Sheep Risk of Contact Tool
The Risk of Contact Tool (RoCT) is an R-based implementation of the Risk of Contact model described in O'Brien et al. (2014). It uses a variety of spatial inputs (including telemetry point data, a core herd home range (CHHR) polygon, a habitat raster model, and a set of active domestic sheep allotments) together with estimates of bighorn sheep foray behavior to estimate the probability and rate of
MapMark4 Shiny: A self-contained implementation of the MapMark4 R package
MapMark4 Shiny is a self-contained R Shiny app designed for quantitative mineral resource assessments. The MapMark4 Shiny app is an implementation of the MapMark4 R package.
Computer programs for the assessment of coal resources (ver. 2.0, April 2021)
The USGS assessment and methodology reports cited within this software release require extensive processing using computational methods and modeling. The most demanding aspects of the modeling were performed using publicly available software: SGeMS and GSLIB (See the 'related External Resources' section on this webpage to learn more about this software). This publication releases the FORTRAN sourc
