Short summary
Our understanding of the drivers of hypoxia fundamentally hinges on patterns of water circulation and vertical mixing that can be difficult to resolve in coastal regions. We identified areas prone to oxygen loss in a complex marine area without knowledge of biogeochemical properties, using only parameters which describe the enclosed seafloors with restricted water exchange. Our approach could help nutrient abatement measures and pinpoint areas where management actions are most urgently needed.
