Replication data for: Holocene sediments from a coastal lake on northern Devon Island, Nunavut, Canada
Abstract: Sediment cores from Lake DV09, northern Devon Island, Nunavut, Canada (75°34”N, 89°18’55”W), were studied to reconstruct the lake ontogeny through analysis and interpretation of the sediment stratigraphy. The lake was uplifted from marine inundation _7600 cal BP. After a millennium of rapi...
