    Estimating mineral surface area and acid sensitivity of forest soils in Kitimat, British Columbia

    Year: 2018, 2018
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Levasseur, Patrick, Thesis advisor (ths): Watmough, Shaun, Degree committee member (dgc): Aherne, Julian, Degree committee member (dgc): Eimers, Catherine, Degree committee member (dgc): Whitfield, Colin, Degree granting institution (dgg): Trent University
    Abstract: <p>In 2012, the Rio Tinto aluminum smelter in Kitimat, British Columbia increased sulphur dioxide (SO2) emissions from 27 to 42 tonnes/day. An initial study was conducted to investigate the effect of the increased sulphur (S) deposition on forest soils. A key uncertainty of the initial study was mineral surface area estimations that were applied to critical load calculations. The current… more

    Moss Biomonitoring of Trace Element Deposition in Northwestern British Columbia, Canada

    Year: 2018, 2018
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Cowden, Phaedra, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Watmough, Shaun, Degree committee member (dgc): Sager, Eric, Degree committee member (dgc): Canners, Richard, Degree granting institution (dgg): Trent University
    Abstract: <p>Atmospheric pollutant deposition poses a risk to ecosystem health; therefore, monitoring the spatial and temporal trends of deposition is integral to environmental sustainability. Although moss biomonitoring is a common method to monitor various pollutants in Europe, offering a cost-effective approach compared to traditional methods of monitoring, it is rarely used in Canada. The focus… more

    Nitrogen Retention of Terricolous Lichens in a Jack Pine Forest in Northern Alberta

    Year: 2018, 2018
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Bird, Adam, Thesis advisor (ths): Watmough, Shaun, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University
    Abstract: <p>The Athabasca Oil Sands in Alberta, Canada is one of the largest point sources emitters of NOx in Canada and there</p><p>are concerns that elevated nitrogen (N) deposition will lead to widespread eutrophication impacts, including altered</p><p>species composition, similar to what has occurred in several parts of Europe. Atmospheric deposition rates as high as</… more

    The Influence of Canopy Water Partitioning on the Isotopic Signature of Plant Water in a Mixed Northern Forest

    Year: 2018, 2018
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Snelgrove, Jenna, Thesis advisor (ths): Buttle, Jim, Degree committee member (dgc): Lafleur, Peter, Degree committee member (dgc): Watmough, Shaun, Degree granting institution (dgg): Trent University
    Abstract: <p>This study seeks to clarify the way in which the differing canopy characteristics among tree species influence the partitioning of precipitation, and therefore the source of water available for plant water uptake, in the Plastic Lake catchment near Dorset, ON. Three dominant tree species were compared: red oak (Quercus rubra), eastern white pine (Pinus strobus), and eastern hemlock (… more
