  Belcourt, Josée (2018-08-30)

  This thesis presents Bayesian geoacoustic inversion of seabed reflection-coefficient data as part of the U.S. Office of Naval Research Seabed Characterization Experiment 2017 at the New England Mud Patch. First, a linearized, ...
• A two-stage matched-field tomography method for estimation of geoacoustic properties 

  Corré, Vanessa (2018-08-16)

  Knowledge of the geoacoustic properties of the ocean bottom is essential for accurate modeling of acoustic propagation in shallow-water environments. Estimates of these properties can be obtained through geoacoustic ...
• Systematics and biostratigraphy of Lower Cambrian trilobites of western Laurentia 

  Bohach, Lisa Lynn (2018-07-20)

  Medial Lower Cambrian strata from continental shelf deposits of western Laurentia yield abundant, low diversity trilobite faunas. New faunas from the Cranbrook and Eager formations (southeastern British Columbia) and the ...
• Seismic studies of the northern Cascadia accretionary prism: sediment consolidation and gas hydrates 

  Yuan, Tianson (2018-07-19)

  This thesis work was directed at aspects of two related problems: (1) sediment compaction and fluid expulsion processes in a subduction margin accretionary prism, and (2) the nature and concentration of gas hydrates that ...
• Geophysical studies of saline fluids in the deep crust 

  Marquis, Guy (2018-07-04)

  Geophysical studies have shown that the lower continental crust, especially in Phanerozoic areas, is commonly more conductive and reflective and has a lower seismic velocity than what is expected from the composition of ...
• Hydrothermal alteration in a modern suprasubduction zone : the Tongo forearc crust 

  Banerjee, Neil Raoul (2018-05-24)

  An extensive suite of hydrothermally altered basalts, gabbros, and plagiogranites, was recovered from the trench-facing slope of the Tonga forearc. The tectonic setting, lithology, and geochemistry of these samples make ...
• Modern and late Holocene climate-tree-ring growth relationships and growth patterns in Douglas-fir, coastal British Columbia, Canada 

  Zhang, Qibin (2018-05-04)

  This thesis investigates nonlinear climate-growth relationships and spatio-temporal variations in radial growth of Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) in coastal British Columbia (BC), Canada. ...
• Temporal patterns in Pacific white-sided dolphin pulsed calls at Barkley Canyon, with implications for multiple populations 

  Kanes, Kristen Samantha Jasper (2018-05-01)

  Evaluation of diel and seasonal patterns in offshore marine mammal activity through visual data collection can be impaired by poor weather and light limitations and by the requirement for costly ship time. As a result, ...
• Relative and absolute timing of tectonothermal events in the Pohjanmaa Belt: A structural study of the Paleoproterozoic coupled Bothnian oroclines, Finland. 

  Dawson, Travis (2018-04-30)

  Studies on the formation of oroclines (bends of originally linear mountain belts) are restricted to Phanerozoic examples. Here I provide a structural, metamorphic and geochronological study of the meta-sedimentary Pohjanmaa ...
• A study of the effects of friction and mixing on the exchange flow through the Bosphorus (Strait of Istanbul) 

  Gerdes, Frank (2018-04-05)

  This thesis presents observations from the Bosphorus (Strait of Istanbul), Turkey, made to study the effects of mixing, entrainment and frictionally induced shear on the dynamics of an exchange flow. The well known ...
• Stratigraphy, conodont taxonomy and biostratigraphy of Upper Cambrian to Lower Silurian platform to basin facies, northern British Columbia 

  Pyle, Leanne (2018-02-26)

  This study establishes the stratigraphic framework and conodont biostratigraphy of Lower Paleozoic strata of the Northern Canadian Cordilleran Miogeocline, which document a non-passive tectonic evolution of the rifted ...
• Mixing and secondary circulation in Juan de Fuca Strait 

  Ott, Michael William (2018-02-23)

  Estuaries, the regions where runoff of fresh water, soil, and contaminants first encounter the ocean, are also primary fishing and recreation areas. It is therefore important to understand the dynamics associated with ...
• Environmental control of stable carbon isotope systematics in Emiliania huxleyi 

  Eek, Magnus (2018-02-14)

  The carbon isotope fractionation in the coccolithophore Emiliania huxleyi constitutes the basis for the paleo-pCO₂ barometry. Under the premise that the carbon isotope fractionation is dependent on the availability of ...
