Holocene environmental change in Rotsee and its impact on sedimentary carbon storage.

ABSTRACT: To assess the long-term impact of climate change and human influence on lakes and their sedimentary carbon storage, paleo-environmental approaches using well-dated lake sediment cores can be employed. Here, we reconstruct carbon mass accumulation rates for organic and inorganic carbon since 13 ka BP in Rotsee, a perialpine lake near the Swiss Alps, using a 12-m sediment core. A multiproxy approach (XRF, carbon and nitrogen isotopes, organic macromolecule chemical compositions, aDNA) was used to explore changes in the lake system that affect sedimentary carbon storage. The Early Holocene (11.8-7 cal ka BP) was characterized by a mixed phytoplankton and watershed-derived provenance of organic matter, and the deposition of inorganic and organic sedimentary carbon.
