Navy Northrop Grumman Particle Tracking version 0.1 Navy Northrop Grumman Particle Tracking version 0.1
This software release contains a generalized workflow to setup particle tracking analyses to assess groundwater travel times at the Navy-Northrop-Grumman site, in Nassau County, New York. This approach uses the posterior "texture model" inset model described by Fienen and others (2024) and made available in Corson-Dosch and others (2023) that simulates groundwater flow in the sole-source...
Code for reproductive habitat mismatch influences chytrid infection dynamics in a tropical amphibian community Code for reproductive habitat mismatch influences chytrid infection dynamics in a tropical amphibian community
This repository contains data and code supporting the Gilbert et. al manuscript entitled, "Reproductive habitat mismatch influences chytrid infection dynamics in a tropical amphibian community". The objective of the paper is to identify the influence of life history, rainfall, and habitat on chytrid infection dynamics in a frog community in Brazil’s Atlantic Forest. The code (see...
Marginalized space-time point process models for inferring animal resource selection and species distribution from telemetry data Marginalized space-time point process models for inferring animal resource selection and species distribution from telemetry data
This project compared methods for estimating large scale patterns of animal resource selection and species distribution to demonstrate the benefits of marginalized space-time point process models.
InQUIRI InQUIRI
This standalone software application provides an integrated set of tools for inferring river discharge Q from remotely sensed data based on critical flow theory, a method introduced by Legleiter et al. (2025). This approach can yield accurate streamflow estimates in rivers with well-defined standing wave trains, referred to as undular hydraulic jumps (UHJ's). Once an image with clearly...
SURF - Seismicity Utilized for Reconstructing Faults - Python Package SURF - Seismicity Utilized for Reconstructing Faults - Python Package
SURF is an algorithm to generate 3D fault models. This algorithm utilizes open-source, well known and documented packages, to generate fault models that require very few user input parameters.
Failure to meet the exchangeability assumption in Bayesian multispecies occupancy models: Implications for study design Failure to meet the exchangeability assumption in Bayesian multispecies occupancy models: Implications for study design
Land managers seek to understand whether treatments they implement effectively achieve their goals to support, or at least not negatively impact, species of concern. This power analysis identifies minimum data collection needs to estimate treatment impacts when baseline species community information is lacking, and when there is significant risk of violating the species exchangeability...
Code for Doe diligence: A regional analysis of antlerless deer harvest regulations in the Midwestern United States of America Code for Doe diligence: A regional analysis of antlerless deer harvest regulations in the Midwestern United States of America
This code uses Nimble to run a Bayesian hierarchical model using both linear and nonlinear features. The model assesses the effects of various changes in white-tailed deer (Odocoileus virginianus) harvest regulations on realized annual antlerless harvest. Eight states participated in this analysis and all data was unified to a common definition through extensive consultation with experts...
ezMCDA: An Interactive Dashboard for Multi-Criteria Decision Analysis ezMCDA: An Interactive Dashboard for Multi-Criteria Decision Analysis
ezMCDA is a user-friendly software to conduct Multicriteria Decision Analysis (MCDA) while considering uncertainty and nonlinear utility functions.
Evaluation of CONUS404 simulations of precipitation, temperature, and net radiation in the Delaware River Basin Evaluation of CONUS404 simulations of precipitation, temperature, and net radiation in the Delaware River Basin
This product is a series of Jupyter Notebook tutorials that are designed to help researchers preprocess data and statistically compare modelled and observational precipitation, temperature, and radiation data. The first notebook walks researchers through setting up their environment, important concepts, querying data sources, and filtering their data to the same temporal and spatial...
Articulated Barrier Shoreface (ABSF) Model Articulated Barrier Shoreface (ABSF) Model
The Articulated Barrier Shoreface (ABSF) Model is a framework to simulate the transgression of a barrier island under sea-level rise, including a dynamic upper (US) and lower (LS) shoreface and overwash components. The model is written in MATLAB and in python, both versions included in this release.
DSWE_GEE v2.0.0 DSWE_GEE v2.0.0
Code for implementation of the Dynamic Surface Water Extent algorithm in Google Earth Engine. Multiple scripts allow the creation of single-scene or composited Dynamic Surface Water Extent (DSWE) images from Landsat (updated for Collection 2 imagery) and MODIS data. All code is written for use in Google Earth Engine in the JavaScript API.
R Script to Run a Simulation-based Power Analysis for Eelgrass Biomass R Script to Run a Simulation-based Power Analysis for Eelgrass Biomass
This script simulates data under an example scenario and applies a model to the simulated dataset to estimate trend, thus evaluating the power to detect the trend. The study was designed to evaluate various scenarios (sampling designs, as well as biological parameters that differ between the two study lagoons).
