Reconstruction of Extreme Paleoclimatic Events in Northwestern Siberia Using Ancient Wood From Fort Nadym
This study addresses the occurrence of damage to the anatomical structure (frost rings, light rings, and fluctuations of the wood density) and missing tree rings in wood samples from Fort Nadym—a medieval fort in the subarctic zone of Western Siberia. The chronology of extreme climatic events was reconstructed for the 1170–1505 period. We used multiple criteria such as severity of events; coincidence of structural pathologies and missing annual r…
Trends In Elemental Concentrations of Tree Rings From the Siberian Arctic
The biogeochemistry and ecology of the Arctic environment have been heavily impacted by anthropogenic pollution and climate change. We used ICP-MS to measure concentrations of 26 elements in the AD 1300–2000 tree rings of larch from the Taymyr Peninsula in northern Siberia for studying the interaction between environmental change and wood chemistry. We applied a two-stage data reduction technique to identify trends in the noisy measurement data. …
Competitive Strength Effect In the Climate Response of Scots Pine Radial Growth In South-Central Siberia Forest-Steppe
This paper presents a method for classification of trees in groups depending on parameters of the age trend in tree-ring width. The method is tested on a sample containing 194 trees of Scots pine (Pinus sylvestris L.) growing in the forest-steppe zone of the South of Central Siberia. The climatic response of tree-ring width in such climatic conditions is complex. The influence of temperature in May-September is negative (moisture reducing). Warm-…
Comparing forest measurements from tree rings and a space-based index of vegetation activity in Siberia
Different methods have been developed for measuring carbon stocks and fluxes in the northern high latitudes, ranging from intensively measured small plots to space-based methods that use reflectance data to drive production efficiency models. The field of dendroecology has used samples of tree growth from radial increments to quantify long-term variability in ecosystem productivity, but these have very limited spatial domains. Since the cambium m…
A 2367-Year Tree-Ring Chronology for the Altai–Sayan Region (Mongun-Taiga Mountain Massif)
Wood material from living trees and trunk remains of Siberian larch (Larix sibirica Ldb) from the upper treeline (2300 m) of the Mongun Taiga mountain massif was used for building up a 2367-year Mongun tree-ring chronology. The chronology is consistent with paleoclimatic data and reflects the main changes in the climate of the Northern Hemisphere over the last two millennia: the cooling of the 6th century, "Medieval warming," "Little Ice Age," an…

Year Tree-Ring Chronology for the Altai-Sayan Region (Western Tuva)
The current paper presents a new 1929-year tree-ring chronology for the Altai-Sayan region (Western Tuva) based on analyses of wood material from living trees and trunk remains of Siberian larch (Larix sibirica Ldb) from the upper treeline (2400 m asl). The correlations between tree-ring indices and meteorological data suggest that maximum effect on radial growth is produced by temperatures in June and July. This makes it possible to use the resu…
Tree-ring growth curves as sources of climatic information
Regional growth curves (RGCs) have been recently used to provide a new basis for removing nonclimatic trend from tree-ring data. Here we propose a different use for RGCs and explore their properties along two transects, one meridional and the other elevational. RGCs consisting of mean ring width plotted against cambial age were developed for larch samples from 34 sites along a meridional transect (55–72°N) in central Siberia, and for 24 sites on …
Summer temperatures in eastern Taimyr inferred from a 2427-year late-Holocene tree-ring chronology and earlier floating series
A brief review is presented of the progress, to date, in constructing a long, continuous ring-width chronology from living and subfossil Siberian larch (Larix gmelinii) in the eastern part of the Taimyr peninsula. A near 2500-year chronology running up to the present has been assembled and several shorter, earlier series have been produced that are dated approximately on the basis of radiocarbon dates. A description is given of the production of …
Tree-ring width and density data around the Northern Hemisphere
Patterns of summer temperature over the Northern Hemisphere, obtained from a calibration of a treering network, are presented for every year from 1600 to 1877. The network of tree-ring density chronologies is shown to exhibit spatially coherent modes of variability. These modes closely match summer half-year tempera ture variations, in terms of similar spatial patterns and similar temporal evolution during the instrumental period. They can, there…
Tree-ring width and density data around the Northern Hemisphere
A detailed description is presented of the statistical patterns of climate forcing of tree growth (annual maximum latewood density and ring-width time series), across a network of 387 specially selected conifer sites that circle the extra-tropical Northern Hemisphere. The in‘ uence of summer temperature dominates growth. A mean April–September response is optimum for describing the major forcing signal over the whole densito-metric network, thoug…
Twentieth-century summer warmth in northern Yakutia in a 600-year context
We report unusual twentieth-century early-summer warmth recorded by larch tree-rings at the north ern tree-line in far northeastern Eurasia (Yakutia). The tree-ring series are strongly replicated and well suited to the detection of fluctuations on interannual to century timescales. They are strongly correlated with local instrumental temperature data. Mean early-summer temperature in the twentieth century significantly exceeds that of any period …
