Description: Drivers of hypoxia and ocean acidification intensification in upwelling shelf systems. Equatorward winds drive the upwelling of low dissolved oxygen (DO), high nutrient, and high dissolved inorganic carbon (DIC) water from above the oxygen minimum zone. Cross-shelf gradients in productivity and bottom water residence times drive the strength of DO (DIC) decrease (increase) as water transits across a productive continental shelf. Variations in source water DO, DIC, and nutrient content, upwelling favorable winds, and shelf processes can all accentuate or dampen the severity of hypoxia and OA exposure.Modified from Gewin (2010) by Moni Kovacs.
