Title

PALAEOVOLCANOS, SOLAR ACTIVITY AND PINE TREE-RINGS FROM THE KOLA PENINSULA (NORTHWESTERN RUSSIA) OVER THE LAST 560 YEARS

Pages

  855-864

Abstract

 The paper deals with the analysis of the external factor (solar activity, VOLCANIC ERUPTIONS) influence on tree growth at the Kola Peninsula, northwestern Russia. Pinus sylvestris L. (Scots pine) tree-ring chronologies collected nearby the northern timberline (68.63N, 33.25E) include the oldest (1445-2005 AD) living pine tree found up to date in the Kola Peninsula. A total of 18 living trees Pinus sylvestris were sampled taking two cores. Tree rings measured with a precision of 0.01 mm by using an image analysis system (scanner and relevant software). The samples were cross-dated using standard dendrochronological practices and the COFECHA program. A negative exponential curve was used to remove the age trend from individual annual ring series prior to construction of the chronology using the ARSTAN modeling. It was shown that the past climatic variations in the Kola Peninsula were fairly strongly connected to solar variability and volcanic activity. A superposed epoch analysis of 18 large (Volcanic Explosivity Index, VEI>5) volcanic events revealed a significant suppression of tree growth for up to 8 years following VOLCANIC ERUPTIONS. The data analysis enabled us to get some conclusions on the past CLIMATE variations and to demonstrate the relation of global and regional climatic variations in the European North.
