NO3GWT version 1.0.0 NO3GWT version 1.0.0
A groundwater Nitrate Decision Support Tool (GW-NDST) for wells in Wisconsin was developed to assist resource managers with assessing how legacy and possible future nitrate leaching rates, combined with groundwater lag times and potential denitrification, influence nitrate concentrations in wells (Juckem et al. 2024). The GW-NDST was reviewed and approved by the journal via this official...
Comparing datasets by surveillance method using spatial models Comparing datasets by surveillance method using spatial models
This software compares statistical methods to model habitat risk of CWD in white-tailed deer in Pennsylvania using Bayesian hierarchical models in R-INLA and compares these results with model output from WinBugs. The software also uses R-INLA with the Stochastic Partial Differential Approach (SPDE) to compare different surveillance methods to model CWD in relation to habitat features and...
Code to Support Hypoxia vulnerability in the salmon watersheds of Southeast Alaska Code to Support Hypoxia vulnerability in the salmon watersheds of Southeast Alaska
Oxygen depletion events (hypoxia) in coastal aquatic ecosystems occur more frequently, yet their causes and consequences remain poorly understood. We identified key drivers of hypoxia in Southeast Alaska watersheds for long-term hypoxia monitoring. This software release contains one R script that can be used to calculate hypoxia risk from environmental variables. This R code will re...
Application of Spatially Misaligned Regression Model to Assess Impacts of White-Nose Syndrome Application of Spatially Misaligned Regression Model to Assess Impacts of White-Nose Syndrome
Code release for a statistical framework that provides a solution to overcome institutionally siloed monitoring activities in order to inform species conservation across large landscapes. Stan code and documentation to provide access and adaptation for other wildlife disease applications.
GRAPES.jl - GRAph Prediction of Earthquake Shaking in Julia (Version 1.0.0) GRAPES.jl - GRAph Prediction of Earthquake Shaking in Julia (Version 1.0.0)
GRAPES.jl is a Julia-language code for earthquake early warning. GRAPES.jl implements the GRAph Prediction of Earthquake Shaking (GRAPES) algorithm using graph neural networks. The GRAPES.jl package provides code for EEW ground motion predictions.
DGMETA (Version 1): Dissolved Gas Modeling and Environmental Tracer Analysis Computer Program DGMETA (Version 1): Dissolved Gas Modeling and Environmental Tracer Analysis Computer Program
DGMETA (Dissolved Gas Modeling and Environmental Tracer Analysis) is a Microsoft Excel-based computer program that is used for modeling air-water equilibrium conditions from measurements of dissolved gases and for computing concentrations of environmental tracers that rely on air-water equilibrium model results. DGMETA can solve for the temperature, salinity, excess air, fractionation of...
