Isotopic evidence of increasing water abundance and lake hydrological change in Old Crow Flats, Yukon, Canada

Autor: Lauren A MacDonald, Kevin W Turner, Ian McDonald, Mitchell L Kay, Roland I Hall, Brent B Wolfe

Publikováno v: Environmental Research Letters, Vol 16, Iss 12, p 124024 (2021)

Lake-rich northern permafrost landscapes are sensitive to changing climate conditions, but ability to track real-time and potentially multiple hydrological responses (e.g. lake expansion, drawdown, drainage) is challenging due to absence of long-term

Multi-year isoscapes of lake water balances across a dynamic northern freshwater delta

Autor: Casey R Remmer, Laura K Neary, Mitchell L Kay, Brent B Wolfe, Roland I Hall

Publikováno v: Environmental Research Letters, Vol 15, Iss 10, p 104066 (2020)

Sustainable approaches capable of tracking status, trends and drivers of lake water balances in complex, remote landscapes are needed to inform ecosystem stewardship and water-security actions. At the Peace-Athabasca Delta (Alberta, Canada), a global

Value of long-term isotope monitoring of an index lake for tracking changes in lake water balances across a northern freshwater landscape

Autor: Arisha Imran, Laura K. Neary, Matthew D. Falcone, Brent B. Wolfe, Roland I. Hall

Publikováno v: Journal of Hydrology: Regional Studies, Vol 53, Iss , Pp 101765- (2024)

Study region: The Peace-Athabasca Delta, northeastern Alberta, a Ramsar Wetland of International Importance. Study focus: To explore the cause of change in water isotope composition at an ‘index lake’ (δSSL; ‘PAD 18’), a terminal basin where

Has Alberta oil sands development altered delivery of polycyclic aromatic compounds to the Peace-Athabasca Delta?

Autor: Roland I Hall, Brent B Wolfe, Johan A Wiklund, Thomas W D Edwards, Andrea J Farwell, D George Dixon

Publikováno v: PLoS ONE, Vol 7, Iss 9, p e46089 (2012)

The extent to which Alberta oil sands mining and upgrading operations have enhanced delivery of bitumen-derived contaminants via the Athabasca River and atmosphere to the Peace-Athabasca Delta (200 km to the north) is a pivotal question that has gene

Use of pre-industrial floodplain lake sediments to establish baseline river metal concentrations downstream of Alberta oil sands: a new approach for detecting pollution of rivers

Autor: Johan A Wiklund, Roland I Hall, Brent B Wolfe, Thomas WD Edwards, Andrea J Farwell, D George Dixon

Publikováno v: Environmental Research Letters, Vol 9, Iss 12, p 124019 (2014)

In the Alberta oil sands region, insufficient knowledge of pre-disturbance reference conditions has undermined the ability of the Regional Aquatics Monitoring Program (RAMP) to detect pollution of the Athabasca River, because sampling began three dec
