The development and application of a technique in dendrochronology
… of analyzing key-year patterns over a wide area. Cross-dating of trees utilizing key-year patterns from living trees and old building timbers was successfully accomplished in Montgomery County, Virginia. Key-year pattern data from both counties were used in a study of the correlation of key-year …

Dendrochronological Potential of Bermuda Cedar
… from this species for historical timber dating or climate reconstruction. Construction of a regional chronology for the island of Bermuda was attempted with 110 cores, 1 partial section, and 1 full section. Using computer assisted cross-dating with independent radiocarbon testing, a …

Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits
… L.) buried in South Swedish peat deposits. By cross-dating Swedish bog-pine ring-width (RW) chronologies with corresponding material from North-west Germany, three Swedish RW chronologies were assigned absolute ages and yielded continuous, dated chronologies over the periods 5284-3728 BC and …

Dendrochronological investigations of living and relict yew trees from eastern England
… from a network of over 150 modern yew trees across eastern England. Analysis of climate-growth relationships reveals an unexpectedly strong signal that enables reconstructing interannual to multi-decadal spring-summer precipitation and mid-summer drought variability for western Europe. Second, …

Potential of above- and below-ground coarse woody debris as a carbon sink in managed and unmanaged forests
… radiocarbon analysis and dendrochronological cross-dating were used to determine the time of tree death for CWD logs. From these data, disappearance times were calculated for the three tree species. In the unmanaged forests, the C stocks in the CWD accumulated to 10 Mg ha-1 in the spruce …

A Multidisciplinary Approach for Determining the Extents of the Beds of Complex Natural Lakes in Louisiana
In Louisiana, the beds of natural lakes are owned by the state. The locations of property boundary lines separating state property from private lands have usually been set by determining the levels of natural monuments known as ordinary high water marks. The term is confusing and subjective, …
