White spruce tree-ring-width data in Old Crow Flats, Yukon Territory, 2007-2008
收藏资源简介：
A network of 23 white spruce sites was established in Old Crow Flats, and tree-ring samples were collected from each site using standard dendrochronological techniques. Cores were collected from living trees and cookies were cut from dead trees. Ring-width series were measured from all samples at the Carleton University Paleoecology Laboratory, and mean site chronologies were calculated for each site. Climate-growth relations of each site were assessed. Regional growth patterns were compared against other white spruce chronologies from across northwestern North America to determine the larger-scale importance of tree-ring growth in Old Crow Flats.
