Overview In this exercise, you'll use Google Earth to examine the global network of tree-ring data. We'll review the geographic distribution of tree-ring records and discuss why tree-ring data are common in some regions and rare in others (or completely absent). This assignment will help you understand why there are geographic biases in the application of tree-ring research and identify frontier regions for future research.
Useful resources Google Earth is available as a free download at http://www.google.com/earth/ index.html. The International Tree-Ring Data Bank is maintained by the NOAA Paleoclimatology Program and the World Data Center for Paleoclimatology at http://www.ncdc.noaa.gov/paleo/ treering.html.
