We are thrilled to announce that Hongsik Kim has successfully defended his PhD thesis: “Economic Impacts of Ocean Deoxygenation on Marine Fisheries and Ecosystems,” which offers a critical interdisciplinary analysis of one of the most pressing threats to marine environments. The thesis is an interdisciplinary examination of how declining oxygen levels in the ocean affect marine life and fisheries, and integrates oceanographic, biological, and economic perspectives to analyze these impacts.
Dr. Kim’s work explored how deoxygenation affects fish physiology, habitat, and food webs. Using innovative methods like the Aerobic Growth Index and ecosystem modeling, the research projects significant future impacts. Case studies on Pacific halibut and East China Sea fisheries suggest potential biomass reductions and economic losses by 2100 under high-emission scenarios. His study also notes that mid-trophic level species and small-scale fishing fleets may be more vulnerable.
The thesis highlights the importance of using interdisciplinary approaches to develop effective management strategies and supports a precautionary approach to fisheries management.
Congratulations, Dr. Kim!
