The International Conference on Ocean Deoxygenation and Marine Species Adaptation (ICODMSA 2026) will be held on June 1, 2026, in the United States. Organized by the World Academy of Science, Engineering and Technology (WASET), this international conference brings together marine scientists, researchers, environmental experts, and academics to explore the impacts of ocean deoxygenation on marine ecosystems and species adaptation. The conference focuses on critical topics including climate change effects on ocean oxygen levels, marine biodiversity conservation, ecosystem resilience, and adaptive mechanisms of marine organisms. Participants will present research findings, attend keynote sessions, and engage in discussions addressing global marine environmental challenges. ICODMSA 2026 provides an important platform for knowledge exchange, scientific collaboration, and innovation in ocean and environmental science.
