• Multicentennial Ring-Width Chronologies of Scots Pine Along a North–South Gradient Across Finland

  Samuli Helama, Markus Lindholm et al.•ARTICLE•Tree-Ring Research•2005

  Añadir item

  Four regional Scots pine ring-width chronologies at the northern forest-limit, and in the northern, middle and southern boreal forest belts in Finland cover the last fourteen centuries. Tree-ring statistics and response functions were examined, and tree-ring width variation was also compared to North Atlantic Oscillation (NAO) and volcanic forcing. The tree-ring statistics show evidence of an ecogeographical gradient along a north–south transect.…

• The supra-long Scots pine tree-ring record for Finnish Lapland

  Open Access•Samuli Helama, Markus Lindholm et al.•ARTICLE•The Holocene•2002•Citada por: 9•Referencias: 2

  Añadir item

  Midsummer (July) temperatures are reconstructed for the last 7500 years using the long ring-width chronology of Scots pine (Pinus sylvestris L.) from northern Finland. The chronology was built using regional curve standardization (RCS), which allows for long-term (low-frequency) variability to be extracted from this annually resolved record of 1087 samples from living trees and subfossil timber. Short-and long-term changes in reconstructed July t…

• The supra-long Scots pine tree-ring record for Finnish Lapland

  Añadir item

  This paper reviews the development of the current ‘supra-long’ pine chronology for northern Finnish Lapland. In the forest-tundra ecotone region of northern Finnish Lapland over 250 samples from living Scots pines (Pinus sylvestris L.) and over 1700 samples of subfossil pines have been collected for dendrochronological studies. In addition, over 1400 subfossils have been sampled from the forested area of Finnish Lapland. The goal of the research …
