Overview

VBVenn is a Visual Basic program that calculates the size and position of two circles to construct a quantitative Venn diagram. It is a simple one-form program with a fairly intuitive user interface.

ZONECONC is a postprocessing program that tabulates concentration statistics from concentration data generated by MODFLOW-GWT.

Computes estimates of survival and capture probability for 1-age class open population capture-recapture models.

Computes estimates of survival and capture probability adjusted for missclassification.

Swarm is a Java application designed to display and analyze seismic waveforms in real-time. Swarm can connect to and read from a variety of different static and dynamics data sources, including Earthworm waveservers, IRIS DMCs, SEED and SAC files, and simple ASCII. Swarm has both time- and frequency-domain analysis tools, along with a simple but powerful mapping platfrom. 

SutraPrep  facilitates the creation of three-dimensional (3D) input datasets for the USGS ground-water flow and transport model SUTRA .

SutraPlot creates 2D and rotatable 3D plots from 2D and 3D SUTRA output data.

A removal model for estimating detection probabilities from point count surveys.

VolatileCalc calculates H2O-CO2-melt equilibrium for the rhyolite and basalt systems.

A Fortran-77 Computer Program to Calculate the Areal Distribution of Mapped Data Points Using Count-Circle Methodology.

Computes estimates of survival and recovery rates for band-recovery data with additional models for estimating reporting rate.

A Double-observer approach for estimating detection probability and abundance from avian point counts.
