This notebook implements the processing of UAS aeromagnetic total magnetic intensity data as described in Phelps and others (2022). After low-pass filtering the raw data and applying a diurnal magnetic correction, a heading and altitude correction model is applied to the data, solved using regularized regression methods; heading refers to the direction in which the sensor is flying. The...

NSHM Hazard Tool, a suite of web tools for the NSHMP.

GSFLOW is a coupled Groundwater and Surface-Water Flow model based on the integration of the U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS; Markstrom and others, 2015) and the U.S. Geological Survey Modular Groundwater Flow Model (MODFLOW-2005, Harbaugh, 2005; MODFLOW-NWT, Niswonger and others, 2011). In addition to the basic PRMS and MODFLOW simulation methods...

The R package webmap creates interactive web maps using the JavaScript Leaflet library with base layers of The National Map (TNM). Map service endpoints are offered with no use restrictions and provide access to base geospatial information that describes the landscape of the United States and its territories. Base layers outside these areas are unavailable at higher spatial scales. This...

This software release contains several R scripts that generate epidemic projections of SARS-CoV-2 in white tailed deer populations using a Susceptible-Infected-Recovered-Susceptible (SIRS) modeling framework. We provide a workflow of vignettes used in Rosenblatt et al. In Prep and Cook et al. In Prep. Users are able to specify transmission parameters for human-deer and deer-deer...

This spreadsheet enables statistical and visual wiggle-matching of sequential radiocarbon ages from a tree-ring chronology to the IntCal20 calibration curve. It will calculate and plot an optimal fit of the samples to the calibration curve and the user can then incrementally move the wiggle-match in time to see the effect in both goodness-of-fit statistics and visually on a graph. This...

This software involves R scripts to download and process large-scale spatial data defined by an extent input by the user. The code then resamples data to the desired resolution, downloads metadata from a public website on West Nile virus prevalence in mosquito pools, then extracts spatial layer data as covariates for each record. Also, this software involves R script to fit models of...

Software package to support regression-based regionalization of streamflow frequency statistics that follow a log-Pearson type III distribution.

AMMonitor is an open source R package dedicated to collecting, storing, and analyzing AMU information in a way that 1) is cost-effective, 2) can efficiently process and store information, and 3) can take advantage of the vast and growing community of R analytics.

Approximate Dynamic Programming relies on forward simulation of the system, so two population projection models are used, one for crabs and one for red knots. The two models are linked: HSC abundance is a predictor variable in the REKN model. Other useful outputs are produced as well, such as predictions of future harvest.

A Google Earth Engine (GEE) application was developed to explore the spatial distribution map of potential percent change (2020 compared to 1985) of design peak-flow, an average percent change (average of pixels within the selected urban area) as text, and three time-series (1985-2020) charts of design peak-flow for three precipitation frequencies (with three recurrence interval and...
