Temperature reconstructions from tree-ring densities overestimate volcanic cooling
The fidelity of inferences on volcanic cooling from tree-ring density records has recently come into question, with competing claims that temperature reconstructions based on tree-ring records underestimate cooling due to an increased likelihood of missing rings or overestimate cooling due to reduced light availability accentuating the response. Here we test these competing hypotheses in the la...
متن کاملLong range correlations in tree ring chronologies of the USA: Variation within and across species
[1] Tree ring width data are among the best proxies for reconstructing past temperature and precipitation records. The discovery of fractal scaling and long-memory in meteorological and hydrological signals motivates us to investigate such properties in tree ring chronologies. Detrended fluctuation analysis and adaptive fractal analysis are utilized to estimate the Hurst parameter values of 697...
متن کاملVolcano-induced regime shifts in millennial tree-ring chronologies from northeastern North America.
Dated records of ice-cap growth from Arctic Canada recently suggested that a succession of strong volcanic eruptions forced an abrupt onset of the Little Ice Age between A.D. 1275 and 1300 [Miller GH, et al. (2012) Geophys Res Lett 39(2):L02708, 10.1029/2011GL050168]. Although this idea is supported by simulation experiments with general circulation models, additional support from field data ar...
متن کاملExtension of New Zealand kauri (Agathis australis) tree-ring chronologies into Oxygen Isotope Stage (OIS) 3
New Zealand kauri (Agathis australis) is both long-lived and sensitive to climate so during the past two decades an extensive network of sites has been sampled for dendrochronological analyses. The network can be divided into three general groups based on the time period they cover— ‘modern’ kauri (MK), late-Holocene kauri (HK) and ‘ancient’ kauri (AK) from before the Last Glacial Maximum (LGM)...
متن کاملComparing Tree-ring Chronologies and Repeated Timber Inventories as Forest Monitoring Tools
Historical information on forest growth is essential to evaluate and understand change in managed and unmanaged forests. Two ground-truth nondestructive sources of information on interannual to interdecadal changes are (a) repeated timber inventories and (b) tree-ring chronologies. I present here a case study of how those two types of data can complement and benefit each other. At the Gus Pears...
