North American Glacial Varve Project
Antevs (Automatic Numerical Time-series Evaluation of Varve Sequences) is a program for correlating glacial varve sequences, and similar time-series data. The program uses Fourier analysis, or optionally curve fitting algorithms such as cubic splines, to remove trends and to normalize the series for comparison. The resulting series are correlated using cross-correlation techniques to identify potential matches. Editing capabilities allow series renumbering once an unknown series is correlated with a known chronology.
Antevs includes techniques for matching tree-ring sequences, and is used extensively in undergraduate student and other research projects in John Rayburn's varve and tree-ring laboratory at SUNY New Paltz. Suggestions from Dr. Rayburn and his students have been the primary motivation for updates, feedback from other users is appreciated, and will likely result in fixes and new features.
