Tree ring dating database
It currently contains 14,341 references dating back to 1737. This database contains brief descriptions of fossil and modern woody dicots (hardwoods) from more than 200 plant families, and is searchable by an interactive, multiple-entry key. Paleo data come from natural sources such as tree rings, ice cores, corals, and ocean and lake sediments, and extend the archive of climate back hundreds to millions of years. The Data Bank includes raw ring width or wood density measurements, and site chronologies (growth indices for a site). Various species of fossilized wood taken under the microscope and shown in tomograms. Juan Pedro Ferrio Díaz, Albert-Ludwigs-Universität Freiburg, Germany: How can we study past climates? Resources for information on tree-ring research (dendrochronology). This yearly updated Bibliography of Dendrochronology is a free searchable archive of printed documents relevant to tree-ring research worldwide. The Inside Wood project integrates wood anatomical information from the literature and original observations into an internet-accessible database (over 40,000 images showing anatomical details) useful for research and teaching. Radial, tangential, and cross-sections of 350 North American woods from the 14-volume rare book The American Woods, published between 18 by the author, Romeyn Beck Hough. National Oceanic and Atmospheric Administration (NOAA), Washington, DC. NOAA Paleoclimatology operate the World Data Center for Paleoclimatology which distributes data contributed by scientists around the world. Scientists and forestry professionals have contributed in the many stages of the production of this atlas, through the collection of ground data on the location of tree species, elaboration of the distribution and suitability maps, production of the photographic material and compilation of the different chapters.
