Lake coring Svalbard 2017

Awarded: NOK 77,999

The Holocene Thermal Maximum (11-5 ka BP) may serve as an analogue for near-future Arctic climate: Like the present, this period was characterized by a combination of high radiative forcing (caused by maximum summer insolation instead of greenhouse gases) and freshwater input from melting Arctic ice sheets. Proxy and modelling evidence suggest that deglacial meltwater fluxes overprinted insolation-driven warming in the Svalbard region, inhibiting overturning circulation and causing cooling. The temporal evolution and climate impacts of this dynamic period remain, however, poorly constrained due to a scarcity of high-resolution paleoclimate datasets. This project aims to address this pressing knowledge gap by generating quantitative paleo-temperature reconstructions from laminated lake sediments, using novel techniques from the emerging field of molecular geochemistry.
