• Constraining Climate Model Projections of 21st-Century Global and Regional Warming 

  Liang, Yongxiao (2023-04-11)

  Different climate models predict different amounts of future warming over the 21st century. Such uncertainty of future warming projections can be narrowed down by emergent constraints identified based on the relationships ...
• N2O Production in the Global Ocean:Controls by Nitrification and Denitrification Pathways 

  Pierce, Rebecca (2023-01-31)

  Nitrous oxide (N2O) is a potent greenhouse gas with a high global warming potential, but the underlying processes behind N2O production and consumption are not well understood. The ocean is known to be a strong source of ...
• The State Dependency of Climate Sensitivity and Cloud Responses to CO2 Doubling 

  Smith, Brandon (2023-01-31)

  Cloud feedbacks are a large source of uncertainty in paleoclimate studies and in the constraint of climate sensitivity, and it is thought that climate sensitivity depends on climate state because of these feedbacks. Here ...
• Time Varying Changes and Uncertainties in the CMIP6 Ocean Carbon Sink from Global to Local Scale 

  Gooya, Parsa (2023-01-06)

  As a major sink for anthropogenic carbon, the oceans slow the increase of carbon dioxide in the atmosphere and regulate climate change. Future changes in the ocean carbon sink, and its uncertainty at a global and regional ...
• Algorithmic Hallucinations of Near-Surface Winds: Statistical Downscaling with Generative Adversarial Networks to Convection-Permitting Scales 

  Annau, Nicolaas J. (2022-12-21)

  Providing timely and accurate small-scale information about weather and climate is challenging – especially for variables strongly controlled by processes that are unresolved by low-resolution (LR) models. Motivated by ...
• Changes in Cross-Equatorial Ocean Heat Transport Impact Regional Climate and Precipitation Sensitivity 

  Oghenechovwen, Oghenekevwe C. (2022-12-01)

  Do changes in how cross-equatorial energy transport is partitioned between the ocean and atmosphere impact the hemispheric climate response to forcing? To find out, we alter the cross-equatorial ocean heat transport in a ...
• Thermal Tolerance Limits and Cardiac Acclimation Potential of Sablefish (Anoplopoma fimbria) Embryos and Yolk-Sac Larvae Incubated at Different Temperatures 

  Schellenberg, Chrissy (2022-09-22)

  Average global ocean temperatures and the frequency and intensity of marine heat waves have been increasing over the last century. Temperature plays a critical role in defining the geographical range of the majority of ...
• A probabilistic prediction of rogue waves from a spectral WAVEWATCH III ® wave model for the Northeast Pacific 

  Cicon, Leah (2022-09-22)

  Rogue waves are unexpected, individual ocean surface waves that are disproportionately large compared to the background sea state. They present considerable risk to mariners and offshore structures when encountered in large ...
• The distribution of trace metals and their relationship to net community production during two marine heatwave events in the subarctic northeast Pacific Ocean 

  Taves, Robyn (2022-04-29)

  The marine biological carbon pump (BCP) leads to the transfer of carbon from the atmosphere to the ocean interior through the growth of photosynthetic plankton in the euphotic zone and subsequent sinking of particulate ...
• Glacial isostatic adjustment modelling of the Coast Mountains of British Columbia 

  Lauch, Maximilian (2022-04-20)

  The Coast Mountains in British Columbia contain over 10,000 km2 of glacial ice. While these glaciers have lost significant mass since the Little Ice Age (LIA; around 300 years before present), the melting rate has significantly ...
• Automatic classification of fish and bubbles at pixel-level precision in multi-frequency acoustic echograms using U-Net convolutional neural networks 

  Slonimer, Alex (2022-04-05)

  Multi-frequency backscatter acoustic profilers (echosounders) are used to measure biological and physical phenomena in the ocean in ways that are not possible with optical methods. Echosounders are commonly used on ocean ...
• Robustness of the parameterization of sub-grid scale wind variability on sea-surface fluxes 

  Endo, Kota (2022-03-30)

  Numerical models of the atmosphere discretize space and time, and are unable to resolve processes smaller than model resolution. As such, the aggregate effects of these sub-grid scale processes must be parameterized when ...
• Spatiotemporal variations of the components of seismic hazard in the Chilean subduction zone 

  Herrera, Carlos (2022-02-24)

  This dissertation presents an analysis of the spatiotemporal variations of strong ground shaking and style of faulting at regional scales in the Chilean subduction zone. These properties are part of the two main components ...
• Monitoring fish using passive acoustics 

  Mouy, Xavier (2022-01-31)

  Some fish produce sounds for a variety of reasons, such as to find mates, defend their territory, or maintain cohesion within their group. These sounds could be used to non-intrusively detect the presence of fish and ...
