Lakes and ponds are extremely abundant in high latitude regions, especially across Arctic permafrost landscapes which are in rapid transition in response to climate change. These freshwater ecosystems act as unique environmental sentinels, integrating and recording environmental changes – past and present – in their basins and bottom sediments, providing information on thermokarst and other processes occurring in their surrounding catchments. This session aims at bringing together paleolimnologists working or interested in high latitude permafrost « limnoscapes », over timescales from the recent past to the entire Holocene and beyond. Presentations from all fields of Arctic paleolimnology are welcome, including physico-chemical investigations of lacustrine archives to biostratigraphy, as well as remote sensing and modelling studies. The session will focus on presenting the current state-of-the-science and fostering exchanges between researchers examining all aspects of lake and pond ecosystem processes and dynamics over various time spans and across widespread geographic regions of the circumpolar North.
