Analysis of laminated sediments from Lake DV09, northern Devon Island, Nunavut, Canada
A 147cm sediment core from Lake DV09, northern Devon Island, Nunavut, Canada (75° 34'34"N, 89° 18'55"W) contains annually-laminated (varved) sediments, providing a 1600-year record of climate variability. A minerogenic lamina deposited during the annual thaw period and a thin dep...
