Lake Baikal - A Touchstone for Global Change and Rift Studies

USGS Fact Sheet
Graph showing percentages of biogenic silica in two Lake Baikal cores. Since diatoms and algae are the most important microorganisms in the lake, biogenic silica is a measure of primary productivity. tadiocarbon ages in years are shown by arrows. First-order changes are caused by glacial (blue)-interglacial (red) cycles, with transitions shown in purple. Second-order fluctuations, such as the peak at 3,770 years, are due to shorter climatic events.
