Pattern Recognition: The Exploration of Machine Learning Algorithms in Archaeological Site Prediction, Fraser River Valley, British Columbia

Golder Associates Ltd., teaming with the Seyem’ Qwantlen Business Group (Kwantlen First Nation), was retained by the Township of Langley to develop a model to predict the location of unrecorded archaeological sites on a 10,000 year-old landscape located in the Fraser River Valley, British Columbia. Conventional predictive modelling techniques are common practice however with the […]

Noble metal nanoparticle plasmonic photocatalysts

Plasmonic catalysis is an emerging technology which holds the promise of utilizing light to facilitate a chemical transformation. Antenna nanoreactor is comprised of a plasmonic core and a transition metal shell in which the plasmonic core can absorb the light and generate the highly energetic electrons (hot electrons) and the transition metal shell receives these […]

Using Machine Learning to Decipher Controls Water Quality

Water in the United States is a valuable resource. It is used from everything from drinking water to tourism. However, by the 1970s, many rivers and coastal areas were severely degraded from decades of using water to assimilate pollution. After billions of dollars spent and decades of effort on all levels of government, the increasing […]

Application of paleolimnological tools for assessing the transfer of marine derived nutrients and toxins to fresh water systems, Nova Scotia Canada: Focus on Alewife within the Gaspereau Lake watershed

This research will focus on using lakes sediments to determine the amount of marine derived nutrients and contaminants that Alewife (Gaspereau) transfer into Gaspereau Lake, Kings County, Nova Scotia. Lake sediment records form an archive that preserves environmental change that has occurred in lakes. In this project lake sediment cores will be collected and analyzed […]

Traitement in situ subaquatique par stabilisation/solidification des sédiments contaminés

La gestion des sédiments contaminés et des risques qu’ils peuvent poser pour l’environnement est un enjeu important au Canada. Les administrations portuaires doivent couramment draguer et transporter des sédiments contaminés. Ce transfert vers le milieu terrestre complexifie la gestion des sédiments contaminés. Ce projet vise à proposer une approche qui permettra, dans certains cas, d’éliminer […]

Development of Remedial Action Objectives for McKay River Watershed Impacted by Open Mines and Steam-Assisted Gravity Drainages

Since the 1960s, the lands of several indigenous communities such as the Fort McKay Métis have been largely impacted by open mines and steam assisted gravity drainages (SAGDs). Such oil sands operations have disturbed large areas, changed geology, hydrogeology, hydrology, aquatic and terrestrial environment, and created a linear disturbance. This research project will map and […]

Quantification du carbone séquestré dans les sols forestiers (secteur de la rivière Romaine)

Les barrages hydroélectriques permettent de fournir une énergie renouvelable. Leur construction implique d’inonder une vaste zone en amont du barrage. Le fait d’inonder un territoire engendre des émissions de gaz à effets de serre dans l’atmosphère. Calculer le bilan carbone des réservoirs hydroélectriques implantés en forêt boréale est difficile, puisque les forêts sont affectées régulièrement […]

Assessment of Climate Change-induced Geohazards for Ice-clad Canadian Volcanoes and Mountains

In Canada’s mountains, climate change is leading to the retreat of glaciers, permafrost thawing and accelerated snowmelt. These factors contribute to a significant increase in slope stability hazards and the risk of landslides, placing numerous communities and critical infrastructure at risk. Volcanoes are particularly vulnerable as they are commonly hydrothermally altered and weakened, thereby compounding […]

Characterization of a new ion source for mass spectrometry

Characterization of the energy distribution of ions generated by the plasma in an Inductively Coupled Plasma Mass Spectrometer (ICP-MS) instrument is necessary for a new ion source in that it influences the ion sampling process, transmission efficiency, focusing, and mass analysis in ICP-MS. These energy distribution phenomena are also analogous to the ion beam that […]
