Journal ArticleDOI
Peat bogs document decades of declining atmospheric contamination by trace metals in the Athabasca Bituminous Sands region
William Shotyk,Peter G. Appleby,Beatriz Bicalho,Lauren J. Davies,Duane G. Froese,Iain Grant-Weaver,Gabriel Magnan,Gabriel Magnan,Gillian Mullan-Boudreau,Tommy Noernberg,Rick Pelletier,Bob Shannon,Simon van Bellen,Simon van Bellen,Claudio Zaccone +14 more
TL;DR: The age-depth relationships show that atmospheric contamination by trace metals (Ag, Cd, Sb, Tl, but also V, Ni, and Mo which are enriched in bitumen) has been declining in northern Alberta for decades.
Journal ArticleDOI
Peat bogs in northern Alberta, Canada reveal decades of declining atmospheric Pb contamination
William Shotyk,Peter G. Appleby,Beatriz Bicalho,Lauren J. Davies,Duane G. Froese,Iain Grant-Weaver,Michael Krachler,Gabriel Magnan,Gillian Mullan-Boudreau,Tommy Noernberg,Rick Pelletier,Bob Shannon,Simon van Bellen,Claudio Zaccone +13 more
TL;DR: Peat cores were collected from six bogs in northern Alberta to reconstruct changes in the atmospheric deposition of Pb, a valuable tracer of human activities as discussed by the authors, showing that Pb contamination has been in decline for decades.
Journal ArticleDOI
Sphagnum Moss as an Indicator of Contemporary Rates of Atmospheric Dust Deposition in the Athabasca Bituminous Sands Region
Gillian Mullan-Boudreau,René J. Belland,Kevin Devito,Tommy Noernberg,Rick Pelletier,William Shotyk +5 more
TL;DR: Given that P has been regarded as the growth-limiting nutrient in bogs, fertilization of nutrient-poor ecosystems, such as these from fugitive emissions of dusts from open-pit mining, may have long-term ecological ramifications.
Journal ArticleDOI
Impact of the Little Ice Age cooling and 20th century climate change on peatland vegetation dynamics in central and northern Alberta using a multi-proxy approach and high-resolution peat chronologies
Gabriel Magnan,Simon van Bellen,Lauren J. Davies,Duane G. Froese,Michelle Garneau,Gillian Mullan-Boudreau,Claudio Zaccone,William Shotyk +7 more
TL;DR: In this paper, the past changes in vegetation communities were reconstructed using detailed plant macrofossil analyses combined with high-resolution peat chronologies (14C, atmospheric bomb-pulse 14C, 210Pb and cryptotephras).
Journal ArticleDOI
Testate amoeba records indicate regional 20th‐century lowering of water tables in ombrotrophic peatlands in central‐northern Alberta, Canada
Simon van Bellen,Simon van Bellen,Gabriel Magnan,Gabriel Magnan,Lauren J. Davies,Duane G. Froese,Gillian Mullan-Boudreau,Claudio Zaccone,Michelle Garneau,William Shotyk +9 more
TL;DR: It is suggested that recent apparent drying of peatlands, which may only be reconstructed by appropriate indicators combined with high chronological control, may affect vulnerability to future burning and promote emissions of CO2.
