What’s Causing Low Oxygen Conditions in the Southern Benguela Upwelling System?

Across the world’s oceans, there are places especially abundant in nutrients and life. They cover around 1% of the ocean but produce a disproportionate amount of fish: 20% of global marine fish catches. The southern Benguela Upwelling System is one such place. But it tends to unpredictable severe low-oxygen conditions, which are life-threatening to sea creatures and livelihood-threatening to local people. Researchers at UCT and their collaborators are figuring out what’s causing these conditions and how to manage them.
