Since 1970, bird populations in the U.S. and Canada have declined by 29%, or almost 3 billion birds, signaling a widespread ecological crisis, a study published in the journal Science reveals. The res...
The third IEEE Canada International Humanitarian Technology Conference (IHTC 2017) will be held in Toronto, Canada on July 20-21, 2017. This unique conference will focus on all areas of technology...
Background: Assessments of the dietary intakes in various populations suggest that pregnant women have difficulty meeting all their nutritional requirements through diet alone. Few large-scale studies...
As the first cabled seafloor observatory that involves a geographically distributed network structure, the Victoria Experimental Network Under the Sea (VENUS) will oversee the deployment of three powe...
In the context of examining the potential usage of safe and sustainable geothermal energy in the Alberta Basin, whether in deep sediments or crystalline rock, the understanding of the in situ stress s...
We present the complete submillimeter data for the Canada-UK Deep Submillimeter Survey (CUDSS) 3h field. The observations were taken with the Submillimeter Common-User Bolometric Array (SCUBA) on the ...
We present the multiwavelength identifications for 23 sources in the Canada-UK Deep Submillimeter Survey (CUDSS) 14h field. The identifications have been selected on the basis of radio and near-infrar...
We present optical, near-infrared (IR) and radio observations of the 3-hour field of the Canada–UK Deep Submillimetre Survey (CUDSS). Of the 27 submillimetre sources in the field, nine have secure ide...
Analyses of sediment cores from two small lakes in the southwest Yukon, Jellybean Lake (60.35°N, 134.80°W, 730-m a.s.l.) and Marcella Lake (60.074°N, 133.808°W, 697-m a.s.l.) provide records of Holoce...
This study was designed with the overriding goal of improving our understanding of the nature, causes, and impacts of past climatic conditions in the High Arctic and to evaluate the potential impacts ...
This thesis aims to combine long high-resolution sediment data with information on sedimentation processes in and around Saanich Inlet, to better understand the seasonal sedimentation mechanisms in Sa...
The depth and nature of the source region of the Kiglapait Layered Intrusion, Labrador, Canada, were experimentally explored using rocks representing the troctolitic bulk composition of the intrusion....
