Ultimate Tree-Ring Web Pages: An extensive set of web pages built by Henri Grissino-Mayer that covers a wide variety of topics related to tree ring research. The site is a good starting point for investigating any aspect of tree ring research.
Lectures in Dendrochronology: A series of PowerPoint presentations developed by Jim Speer, Paul Krusic, and Henri Grissino-Mayer for use in instructional settings. The presentations provide introductory information on the practice of dendrochronology and relevant background information.
North American Dendroecological Fieldweek: An instructional program held in a different location each year. The program provides participants with hands on experience and is appropriate for a wide range of experience levels.
International Tree-Ring Data Bank Forum: A cyberspace discussion of all facets of tree-ring research in which many experienced dendrochronologists participate. The forum is a good source of details on many techniques and includes a searchable archive.
Crossdating Tutorial: A series of instruction web pages created by Paul Sheppard that explain the technique of cross-dating and include an interactive application for skeleton plotting. The interactive application provides a convenient way to practice crossdating and learn the technique before working with real samples.
International Tree-Ring Data Bank: Part of the National Oceanic and Atmospheric Administration’s paleoclimatology effort, the database is the primary public repository of raw and processed tree-ring data. Data may be searched in a variety of ways and downloaded.
Bibliography of Dendrochronology: A searchable database containing all types of publications on topics related to tree rings. Henri Grissino-Mayer continuously updates the database, a useful resource for finding publications not included or poorly indexed in other databases.
Dendrochronology Program Library: A collection of free software programs produced by the Laboratory of Tree-Ring Research. The programs allow manipulation and statistical processing of tree-ring data files, and are widely used by the dendrochronology community.
University of Arizona Laboratory of Tree-Ring Research: The first Laboratory dedicated to tree ring research, and still a leader in a variety of tree-ring subdisciplines.
Lamont-Doherty Earth Observatory Tree-Ring Lab: Part of Columbia University, the lab is a world-wide leader in Dendroclimatology
Cornell Tree-Ring Laboratory:
An established tree ring laboratory focused on tree-ring research in the northeastern
United States, Near East, and Aegean regions.
Tree-Ring Society: a scientific association for the promotion of tree-ring research that publishes the journal Tree-Ring Research.
