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 (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 gases, or
REDPy - Repeating Earthquake Detector in Python (Version 1.0.0)
REDPy (Repeating Earthquake Detector in Python) is a tool for automated detection and analysis of repeating earthquakes in continuous data. It works without any previous assumptions of what repeating seismicity looks like (that is, does not require a template event). Repeating earthquakes are clustered into families based on waveform similarity via cross-correlation across multiple stations. All d
Population Viability Model for Western Pond Turtle
The code herein uses a triple loop structure to simulate a spatially implicit stage structured matrix model for two species of western pond turtle with parametric uncertainty and temporal stochasticity.
digger: A python package for D-Claw model inputs
Digger is a python package that provides a number of pre- and post-processing tools for working with the D-Claw model.
R code for calculating imperilment of freshwater fish with a Bayesian belief network
This R script is reproduces a Bayesian belief network built within the propriety software program, Netica. The R- and Netica-based belief networks were used in Dunn and Schumann et al. (in press), which presents an approach for calculating imperilment of freshwater fishes.
algaeClassify
The goal of algaeClassify is to facilitate the analysis of taxonomic and functional trait data for phytoplankton.
Population Viability Model for Spot-tailed earless lizard
Code for simulating Spot-tailed earless lizard populations under habitat loss and road mortality threats in central Texas
Predicting fish responses to climate change using a joint species, spatially dependent physiologically guided abundance model
Predicting the effects of warming temperatures on the abundance and distribution of organisms under future climate scenarios often requires extrapolating species-environment correlations to thermal conditions not currently experienced by a species or to temperatures that exceed the range of observed data. For poikilotherms, incorporating species’ thermal physiology to inform extrapolations under
Population genetic structure of white-tailed deer using microsatellites i the Mid-Atalntic region
Results of 11 microsatellites for white-tailed deer collected in Maryland, New York, Ohio, Pennsylvania, and Virginia from 2014 to 2022 for genetic analysis. In this project we assessed genetic structure using different analyses, and evaluated the performance of assignment tests to correctly match deer to origin (defined as genetic cluster, state or physiographic province). This repository include
CalPUR-LUE
Estimating High Resolution Multi-Cropped Irrigated Land Use Using a Pesticide Use Reporting Database in California
Estimating the amount of water needed for agriculture is vital for food and water security. These estimates rely on maps of crop type and acreage that have limited ground-truthing or represent multiple years or regional cropping patterns. In regions where crops change frequently or m
Numerical model of coastal Erosion by Waves and Transgressive Scarps (NEWTS)
The Numerical model of coastal Erosion by Waves and Transgressive Scarps (NEWTS) model is a framework to simulate the erosion of a closed-basin coastline through time by fetch-dependent erosion or uniform erosion. The model is written in MATLAB and the MATLAB Image Processing Toolbox and a MEX compiler are required.
