Zhigansk floodplain, Yakutia, Russia - russ207 Additional Information Andrea H. Lloyd, Andrew G. Bunn, and Logan Berner Purpose of Collection: Ecology Cores and cross-sections are stored at: Middlebury College Reference: Manuscripts currently in review Notes: Site was outside the town of Zhigansk, on the floodplain of a tributary to the Lena River. There is some human disturbance (in the form of cut stumps) near the site. This file contains all of the measured trees. Trees have been crossdated, but some cores contain persistent problems that were not resolved. We advise users to examine COFECHA output prior to use-- for climatological studies, users will probably want to eliminate a few cores with persistent problems.
