Life under the ice: Under ice convection

PhyLOZooPhy – Coupling Physics on Lake Onego with Zooplankton and Phytoplankton

Winter limnology studies have remained limited in the past but the interest is now rapidly growing in a context of climate change. This research program aims at investigating life under ice and relevant physical and biological processes. In particular, we are interested in understanding under-ice convection and its implication for ecosystem development.

The research program is a collaborative study between laboratories in Switzerland and the Northern Water Problems Institute (NWPI), Karelian Research Center in Russia. This project involves field work in Lake Onego during the winter.
