Lake sediment monitoring Tiefer See | TERENO Northeast
With our long-term and comprehensive monitoring at Lake Tiefer See in Mecklenburg-Western Pomerania with seasonally stratified (warved) sediments, we pursue two overarching goals: (1) measuring the effects of climate change on the lake system and (2) calibrating the sediment archives to reconstruct past climate and environmental changes with a seasonal time resolution.
The lake sediment monitoring at Lake Tiefer See for the integrated analysis of climate and landscape development is part of the TERENO Observatory Northeast Germany and has been in operation since 2012.
