Measured parameters include varve thickness, magnetic # susceptibility, clay/sand/silt, loss-on-ignition, and sediment greyscale. Lake DV09 has a surface area of 3ha, # 16m maximum depth, pH of 8.4, and is located 1.3 km from the coast. Bedrock is Middle Ordovician Bay Fiord Formation, # soils are Cryic regosols, and vegetation is Northern Arctic tundra. # # Additional References: # Courtney Mustaphi, C.J. 2008.

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. #------------------ # Funding_Agency # Funding_Agency_Name: Natural Sciences and Engineering Research Council of Canada (NSERC) # Grant: #------------------ # Funding_Agency # Funding_Agency_Name: Canadian Foundation for Climate and Atmospheric Sciences (CFCAS) # Grant: #------------------ # Site_Information # Site_Name: Lake DV09 # Location: North America>Canada>Nunavut # Country: Canada # Northernmost_Latitude: 75.5761 # Southernmost_Latitude: 75.5761 # Easternmost_Longitude: -89.3153 # Westernmost_Longitude: -89.3153 # Elevation: 35 m #------------------ # Data_Collection # Collection_Name: DV09T2013MS # Earliest_Year: 7500 # Most_Recent_Year: 50 # Time_Unit: Cal.
