Bastien Queste

Bastien Queste serves as an Associate Senior Lecturer in the Department of Marine Sciences at the University of Gothenburg, Sweden, where he leads cutting-edge research on ocean deoxygenation and biogeochemical cycles using autonomous observational platforms. His work addresses critical gaps in climate modeling related to oxygen minimum zones and small-scale ocean processes.

His research centers on oxygen minimum zones (OMZs) and their role in marine ecosystems, carbon/nitrogen cycling, and greenhouse gas production. He investigates how physical processes—from large-scale circulation to submesoscale eddies—influence oxygen supply and consumption across global oceans, with fieldwork focused on the Arabian Sea, Baltic Sea, and Antarctic regions. Queste's approach combines autonomous gliders, satellite data, and in-situ measurements to resolve processes that conventional climate models fail to capture due to grid limitations.

Analysis of his 15 most recent publications reveals a dominant focus on ocean deoxygenation mechanisms, carbon cycle dynamics, and climate change impacts. Key trends include the ventilation of OMZs by water masses like Persian Gulf Water, sea-ice regulation of carbon dioxide uptake, methane emissions from anthropogenic sources, and ice-ocean interactions in polar regions. His methodology consistently leverages autonomous platforms for high-resolution observations across diverse marine environments.

Queste directs the FLOW Lab (Fluxes in Low Oxygen Waters), which investigates low-oxygen water dynamics through interdisciplinary collaboration. The lab's work integrates physical oceanography, biogeochemistry, and climate science to improve predictive models of ocean deoxygenation under future climate scenarios.
