A multi-proxy lacustrine record of Holocene climate change on northeastern Baffin Island, Arctic Canada
Reconstructions of past environmental changes are critical for understanding the natural variability of Earth’s climate system and for providing a context for present and future global change. Radiocarbon-dated lake sediments from Lake CF3, northeastern Baffin Island, Arctic Canada, are used to reconstruct past environmental conditions over the last 11,200 years. Numerous proxies, including chi...
متن کاملHolocene alpine glaciation inferred from lacustrine sediments on northeastern Baffin Island, Arctic Canada
With accelerated melting of alpine glaciers, understanding the future state of the cryosphere is critical. Because the observational record of glacier response to climate change is short, palaeo-records of glacier change are needed. Using proglacial lake sediments, which contain continuous and datable records of past glacier activity, we investigate Holocene glacier fluctuations on northeastern...
متن کاملVertical distribution patterns of copepods, chlorophyll, and production in northeastern Baffin Bay
High resolution vertical distributions of chlorophyll and zooplankton were collected with an instrumented Batfish vehicle in northeastern Baffin Bay. The dominant copepod species wc1.e Calanusfinmllrchicus, Calanus glncinlis, and Calanus hyperlporeus V and VI. Copepod layers consisting of C. jkmclr-chicus and C. glncialis were commonly situated ~3-4 m above the chlorophyll maximum in a depth re...
متن کاملHolocene glaciation and climate evolution of Baffin Island, Arctic Canada
Lake sediment cores and cosmogenic exposure (CE) dates constrain the pattern of deglaciation and evolution of climate across Baffin Island since the last glacial maximum (LGM). CE dating of erratics demonstrates that the northeastern coastal lowlands became ice-free ca.14 ka as the Laurentide Ice Sheet (LIS) receded from its LGM margin on the continental shelf. Coastal lakes in southeastern Baf...
متن کاملHolocene Fire History of a Coastal Temperate Rain Forest Based on Soil Charcoal Radiocarbon Dates
The long-term role of fire in coastal temperate rain forest is poorly understood. To determine the historical role of fire on western Vancouver Island (British Columbia, Canada), we constructed a long-term spatially explicit fire history and examined the spatial and temporal distribution of fire during the Holocene. Two fire-history parameters (time-since-fire [TSF] and fire extent) were relate...
