Reconstruction of the temperature regime of Bol’shoe Miassovo Lake on the basis of regional diatoms termoindication properties

Abstract

Diatom assemblages from the top levels of botton sediments in Lake Bol’shoe Miassovo (Southern Urals) has been studied. On the basis of species composition and termoindication properties of algae a reconstruction of the thermal regime of the lake for the last 1000 years is made. It is established that its significant change was caused by rapid climate warming that began in the 19th century in the Southern Urals.
