Ice Core Analysis with Biogenic Material


Ice cores provide well preserved proxies of the paleo-environment and are usually analyzed by physical and chemical methods. Snow algae can be also used in the ice core analyses as indicators of the paleo-environment (Yoshimura et al., 2000; 1997). Biomass and community structure of algae in a layer of the ice core may reflect the environment at the time when the algae grew on the surface of the glacier. Thus, it is important to understand the ecology of snow algae in studies of glacial variations and ice-cores.

Ice core drilling on Devon Icecap in Canadian Arctic

An ice core drilling from the Belukha Plateau in Altai Mountains. The core is from about 170 m in depth, almost bedrock of the glacier. The core contains stones from the bedrock.
