*Multiproxy reconstruction of past climate and environmental change from Inutoqqat Nunaat, north Greenland from 7 ka to present
Description: Using bulk geochemistry, diatom speciation data, and long-chain alkenones preserved in sediment cores from Nedre Midsommersø and Latesommersø to reconstruct past changes in local temperature, lake ice cover, and moisture availability. Results are paired with new radiocarbon dates on archeological bone material to discuss the climatic and environmental context for human settlement patterns in northernmost Greenland.
Status: Publication in preparation
Reconstruction of Holocene glacial activity in Inutoqqat Nunaat using sediment cores from Nedre Midsommersø
Description: Using grain-size distribution, bulk geochemistry, and diatom speciation data in lake sediment cores from Nedre Midsommersø to investigate past changes in regional glacial activity

A High-Resolution Record of Temperature Trends in Inutoqqat Nunaat over the Past Millennium
Description: Using lipid biomarkers preserved in annually varved lake sediments from Lake South West in Inutoqqat Nunaat to reconstruct past changes in water temperature at high resolution. Results span the last millennium, providing valuable insight into the environmental conditions experienced by the Thule people.
