A preliminary reconstruction (A.D.1635-2000) of spring precipitation using oak tree rings in the western Black Sea region of Turkey. International Journal of Biometeorology. 49:297-302 ABSTRACT: Tree-ring data for Turkey are crucial to the understanding of the climatological effect of drought and rainfall from one era to the next. To this end, the present study reconstructed precipitation patterns in the western Black Sea region of Turkey. Tree-ring widths of oak trees were used to reconstruct March–June precipitation patterns for the years A.D. 1635–2000. According to the findings, during the past four centuries drought events in this region persisted for no more than 2 years, and extreme dry and wet events occurred generally in 1-year intervals. Historical records of droughts in Anatolia and neighboring countries corroborate the data furnished by tree-ring widths to indicate that major droughts and famine events occurred in 1725, 1757, 1887, 1890–1891, 1893–1894 and 1927–1928. GEOGRAPHIC REGION: NW Turkey, Western Black Sea Region PERIOD OF RECORD: 1635-2000 AD DESCRIPTION: The data set is a high-frequency 365-year March-June precipitation reconstruction for a region. The reconstructed values for each year, including particularly dry and wet years, are of equal precision. The oak tree-ring data used for the reconstruction includes 42 stem discs, 20 from living trees and 22 from old constructions. These data are included in the International Tree Ring Data Bank: http://www.ncdc.noaa.gov/paleo/treering.html site turk034 "Around Pinarbasi". Methods included the testing and use of standardized tree-ring sample data and negative exponential or linear regression for detrending; regression analyses, adjustment of temporal variance, and other standard dendroclimatic methods (Cook and Kairiukstis 1990). All are discussed in the references.
