• Tsunamigenic potential of crustal faults in the southern Strait of Georgia and Boundary Bay 

  Caston, Megan (2021-08-31)

  In this thesis, I constrain rupture scenarios of active crustal faults in the southern Strait of Georgia and Boundary Bay in order to assess their tsunamigenic potential. The NW-SE-trending Drayton Harbor, Birch Bay, and ...
• Seasonal forecast skill and potential predictability of Arctic sea ice in two versions of a dynamical forecast system 

  Martin, Joseph Zachary (2021-08-31)

  As the decline in Arctic sea ice extent makes this region more accessible, the need is increasing for effective seasonal sea ice forecasting to facilitate operational planning. Recently, coupled global climate models (CGCMs) ...
• Dinoflagellate cysts across the Cretaceous–Paleogene (K/Pg) boundary in the North Pacific; biostratigraphy, diversity, and paleoenvironmental reconstructions 

  McLachlan, Sandy Melvin Stuart (2021-08-31)

  The central objective of this study is to understand phytoplankton community response following the global mass extinction event at the Cretaceous–Paleogene (K/Pg) boundary. The objective is approached through analysis of ...
• Twenty-first century wind and solar energy potential in northern Canada 

  Van Vliet, Laura (2021-08-30)

  Northern regions of Canada are of special interest for renewable energy investment due to the high cost of traditional energy generation in remote communities (Das & Canizares 2016b). However, climate variability and change ...
• High temperature forearc metamorphism and consequences for sulfide stability in the Pacific Rim Terrane, British Columbia 

  Geen, Alexander C. (2021-06-25)

  The Pacific Rim Terrane in British Columbia is a group of fault-bound forearc metasedimentary and metaigneous rocks subcreted to Wrangellia, comprising three lithological units: the Leech River Complex (LRC), the Pandora ...
• Empirical bifurcation analysis of atmospheric stable boundary layer regime occupation 

  Ramsey, Elizabeth (2021-05-18)

  Turbulent collapse and recovery are both observed to occur abruptly in the atmospheric stable boundary layer (SBL). The understanding and predictability of turbulent recovery remains limited, reducing numerical weather ...
• Blue carbon storage in the Cowichan Estuary, British Columbia 

  Douglas, Tristan (2021-05-10)

  The capacity of the world’s coastal ecosystems to sequester carbon dioxide (CO2), termed “Blue Carbon,” has been a major focus of research in recent decades due to its potential to mitigate climate change. Vegetated coastal ...
• Imaging major Canadian sedimentary basins and their adjacent structures using ambient seismic noise (and other applications of seismic noise) 

  Kuponiyi, Ayodeji Paul (2021-05-05)

  Over a decade ago, it was discovered that the earth’s natural seismic wavefields, propagating as seismic noise, can be processed using correlation methods to produce surface waves, similar to those generated by earthquakes. ...
• Comprehensive study of seismic waveform similarity: applications to reliable identification of repeating earthquakes and investigations of detailed source process of induced seismicity 

  Gao, Dawei (2021-05-05)

  This Ph.D. dissertation focuses on a comprehensive study of seismic waveform similarity aiming at two themes: (1) reliable identification of repeating earthquakes (repeaters) and (2) investigation of the detailed source ...
• Conceptualizing the hydrogeothermal system at Sloquet Hot Springs on unceded St'at'imc territory in southwestern British Columbia 

  Van Acken, Ashley (2021-04-29)

  Geothermal research in the southern Canadian Cordillera has typically focused on hot spring systems and predicting maximum temperatures at depth, estimating fluid circulation depths, and investigating the distribution of ...
• An investigation of low-temperature off-axis hydrothermal systems using lithium isotopes and trace element geochemistry 

  Seyedali, Minasadat (2020-10-26)
