An article resulting from a National Science Centre (NCN) project led by Wojciech Tylmann has just been published in the Journal of Paleolimnology. In the paper, the research team examined the mechanisms behind the formation of modern varves in Lake Gorzyńskie. Using three years of limnological observations, hydrochemical and hydrobiological analyses, and sediment trap monitoring, the authors traced seasonal changes in the supply of material to the lake bottom. They found that more than 90% of the sediment mass is deposited in spring and summer. Of particular interest is the fact that sediment lamination is preserved despite bottom waters remaining oxygenated for many months. The results help us better understand how these valuable archives of environmental change form, and how increasingly mild winters may affect them.
