Researcher at University of Washington studying ocean oxygen and ventilation
Why do we care about oxygen in the ocean? Well, because things living there need to breathe
And unlike those of us breathing air, ocean organisms can’t always rely on there being enough O2. Without sunlight for plants to grow below ~200m, ventilation is the main O2 supply for most of the ocean
