The lake was uplifted from marine inundation ~7600 cal BP. After a millennium of rapid sediment accumulation, which coincided with the Holocene Thermal Maximum in the region, accumulation rates decreased over the past 6000 years as the Arctic became colder. This resulted in the deposition of very fine laminae that were interpreted as varves. The uppermost laminated sediments provided a ~1600 year history of annual sediment transport and deposition into the lake. During periods of warmer temperatures, such as between 6000 and 7500 cal BP and during the Medieval Climate Anomaly (~950-1300 CE; CE, Christian Era), hydroclimatic and permafrost slope processes increased sedimentation rates into the basin. STUDY NOTES: Multiproxy data from 2 sediment cores collected in Lake DV09, Devon Island, Nunavut, Canada, as presented in Courtney Mustaphi and Gajewski (2013) Figures 2, 4, 5, and 6. Measured parameters include varve thickness, magnetic susceptibility, clay/sand/silt, loss-on-ignition, and sediment greyscale.
