• Biogenic silica dynamics of Arctic marine ecosystems 

  Giesbrecht, Karina (2019-04-05)

  Marine diatoms are the dominant primary producers in coastal and shelf regions, and contribute to about 20% of the annual photosynthesis on Earth. Diatoms also exert a major control on the marine silicon (Si) cycle through ...
• Molecular composition and isotope mapping of natural gas in the British Columbia Natural Gas Atlas 

  Evans, Curtis (2019-01-31)

  This thesis provides a geochemical interpretation of natural gas resources in north eastern British Columbia (NEBC), Canada. The work is part of the three-year project, British Columbia Natural Gas Atlas (BC-NGA) to collect ...
• Regime occupation and transition information obtained from observable meteorological state variables in the stably stratified nocturnal boundary layer 

  Abraham, Carsten (2019-01-15)

  The stably stratified nocturnal boundary layer (SBL) can be classified into two distinct regimes: one with moderate to strong winds, weak stratification and mechanically sustained turbulence (wSBL) and the other one with ...
• Modelling sea-ice and oceanic dimethylsulfide production and emissions in the Arctic 

  Hayashida, Hakase (2019-01-04)

  Recent field observations suggest that the radiative forcing of aerosol and clouds in the Arctic may be seasonally regulated by the oceanic emissions of the climatically-important biogenic trace gas dimethylsulfide (DMS). ...
• Reconstructing Holocene East Asian climate and oceanographic history of the northern South China Sea: high-resolution records of pollen, spores, and dinoflagellate cysts 

  Li, Zhen (2019-01-02)

  This study contributes to developing terrestrial and marine palynological indicators of winter or summer monsoon signals as well as oceanographic environments of the South China Sea (SCS). The high-resolution reconstructions ...
• Mapping aquifer stress, groundwater abstraction, recharge, and groundwater’s contribution to environmental flows in British Columbia 

  Forstner, Tara (2019-01-02)

  Groundwater is considered a reliable resource, relatively insensitive to seasonal or even multi-year climatic variation, however quantifying aquifer-scale estimates of stress in diverse hydrologic environments is particularly ...
• Tidal flows, sill dynamics, and mixing in the Canadian Arctic Archipelago 

  Hughes, Kenneth (2018-11-26)

  The transport of low-salinity waters through the Canadian Arctic Archipelago links the North Pacific, Arctic, and North Atlantic Oceans. This transport is influenced by many related small-scale processes including mixing, ...
• Of warming nights and shifting winds 

  Stone, Dáithí Alastar (2018-11-22)

  The attribution of recent global warming to anthropogenic emissions is now well established. However, the relation of recent changes in other properties of the climate system to human activities is not as clearly understood. ...
• Mixing processes near boundaries 

  Colbo, Keir Murray (2018-11-14)

  Using a large eddy simulation (LES) model the cross-cell diffusion of neutrally buoyant and buoyant particles in Langmuir circulation is studied. The non-dimensional diffusivity is found to asymptote to a constant value ...
• Interdisciplinary insights into paleoenvironments of the Queen Charlotte Islands/Hecate Strait region 

  Hetherington, Renée (2018-11-13)

  Subsequent to the Last Glacial Maximum (LGM), complex coastal response resulted from deglaciation, eustatic sea-level change, and a relatively thin, flexible lithosphere in the Queen Charlotte Islands (QCI) region of ...
• Modelling studies of glacial-interglacial transitions 

  Yoshimori, Masakazu (2018-11-05)

  Glaciation/deglaciation is one of the most extreme and fundamental climatic events in Earth's history. The origin of the glacial-interglacial cycles has been explored for more than a century and the astronomical theory is ...
• Velocity structure of S.W. British Columbia, and N.W. Washington, from 3-D non-linear seismic tomography 

  Ramachandran, Kumar (2018-10-25)

  This thesis applies three-dimensional (3-D) non-linear seismic tomography to image crustal/upper mantle structure of S.W. British Columbia and N.W. Washington. Two tomographic inversions are carried out including high-resolution ...
• 3-D seismic investigations of northern Cascadia marine gas hydrates 

  Riedel, Michael (2018-10-23)

  This dissertation presents results from 3-D (parallel 2-D) high resolution seismic surveys and associated studies over an area with deep sea gas hydrate occurrence. The study area is located on the accretionary prism ...
• The impact of the 1989 Exxon Valdez oil spill on phytoplankton as seen through the dinoflagellate cyst record 

  Genest, Maximilien (2018-09-28)

  Our knowledge of how oil spills affect coastal environments is severely limited by the shortage of research that addresses the impact of these events on phytoplankton, the single most important group of organisms in the ...
