Featured Dissertation: Physical Controls on Extremes of Oceanic Carbon and Oxygen in Coastal Waters

by Zelalem M. Engida

UVic News recently announced that “Times Higher Education released its 2020 world university rankings by subject for physical sciences and psychology, placing UVic programs in these areas among the Top 200 around the globe”. To celebrate, we would like to feature some of our graduate research associated with those disciplines.

Today, we feature research in Earth and Ocean Sciences: https://dspace.library.uvic.ca/handle/1828/11209

Abstract (excerpt):

The west coast of Vancouver Island is located at the northern end of the California Current System, one of the world’s Eastern Boundary Current Systems. The region is characterized by wind driven coastal upwelling and high productivity, which supports fisheries and related industries. Climate change poses a challenge to these industries by increasing seawater acidity and decreasing dissolved oxygen levels, which are two of the multi-stressors of marine organisms. This thesis explores the relative importance of different physical and biological mechanisms that affect oxygen and carbon extremes in the region.
(…)
This thesis has identified relative locations within the study domain of priority for effective monitoring of dissolved oxygen and carbon extremes in the study region. Finally, joint DIC- O2 extreme events are found to be common at the end of the summer. This information can be used to inform adaptation and mitigation plans aimed at protecting the economic and bequest value of the coast from potential hazards associated with oxygen and carbon extremes.

*UVic’s open access repository, UVicspace, makes worldwide knowledge mobilization possible. Through this platform, researchers at any institution have access to dissertations (and theses and graduate projects) published by our graduate students. This also makes works available to the interested layperson, who may be engaged in learning more about the research being done at UVic, with no paywall. UVic’s graduate students are doing valuable research every day – but sometimes it goes unsung. Our goal with this series is to shine a light on our students by featuring excellence, one achievement at a time.
