We simulated three heavy summer precipitation events in Alberta, Canada, using the Weather Research and Forecasting (WRF) model and compared the output precipitation data with observations to determine model accuracy. Each storm was simulated multiple times, using five different cumulus...
Tidewater outlet glaciers drain approximately 47% of the ~105,000 km^2 covered by ice caps in the Queen Elizabeth Islands of Nunavut, Canada, suggesting that iceberg discharge may be an important process in the mass balance of these ice caps. Seasonal and inter-annual velocity changes of...
Variations in climatic conditions from the Cayman Islands through stable isotope and element analysis from corals and sediment cores; a 500,000 year recordDownload
The Caribbean region is particularly important to understanding global climate change and feedback systems because the tropics are the primary source of heat and water vapor for the atmosphere. The Caribbean region, however, is a relatively understudied area in terms of tracking climate change...
Variability in Summer Anticyclonic Activity over the Canadian Arctic Archipelago and west Greenland in the late 20th/early 21st centuries, and its impact on the firn stratigraphy of the Devon Ice CapDownload
Significant summer warming over the Canadian Arctic Archipelago (CAA) is linked to a doubling in the frequency of anticyclonic circulation over the region since 2007. The frequency of positive anomalies in summer 500 hPa geopotential height is related to Arctic sea ice volume/thickness in April,...
Using drilled-undrilled shell damage analysis to estimate crushing predation frequencies in modern marine gastropod assemblagesDownload
Predation is a frequently studied subject, but estimating crushing predation in mollusk communities is challenging. Shells record successful attacks, but it is not always possible to identify attacks on an individual basis. Repair scar frequency is a common proxy for crushing mortality, but shell...
Using a novel approach to precisely measure the sedimentation velocity of a (bio)chemical sediment: cyanobacteria-ferrihydrite aggregatesDownload
Banded iron formations (BIF) are iron-rich (~20-40% Fe), siliceous (~40-50% SiO2), and organic-lean (<0.5 wt.%) sedimentary deposits that precipitated widely during the late Archean (2.7-2.5 Ga) and Paleoproterozoic (2.5-1.8 Ga). As cyanobacteria evolved, the reaction between dissolved Fe(II) and...
Using TLS-measured Tree Attributes to Estimate the Above Ground Biomass of Individual Small Black Spruce Trees in Canadian Boreal Forest PeatlandsDownload
Earth’s changing climate poses a number of potential issues for people around the globe. It has become increasingly important for researchers to have the ability to collect good data and build accurate, robust climate models that can help influence the direction of policy makers to mitigate the...
Interest in park services and understanding leisure decision making has become increasingly important in the last fifty years. Canadians in particular have an affinity for spending time in natural areas and often in parks. Parks and protected areas provide a reasonable and approachable place for...
