Sensitivity of hypoxia predictions for the northern Gulf of Mexico to sediment oxygen consumption and model nesting

Abstract: [1] Every summer, a large area (15,000 km 2 on average) over the Texas-Louisiana shelf in the northern Gulf of Mexico turns hypoxic due to decay of organic matter that is primarily derived from nutrient inputs from the Mississippi/Atchafalaya River System. Interannual variability in the size of the hypoxic zone is large. The 2008 Action Plan put forth by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force, an alliance of multiple state and federal agencies and tribes, calls for a reduction of th… Show more

“…However, sediment-water flux parameterizations are a coarse representation of sedimentwater interaction, and typically do not capture nonlinearities in nutrient fluxes that occur under hypoxic/anoxic conditions. Moreover, the choice of parameterization can have a significant effect on model results as shown in Fennel et al (2013) where different parameterizations of SOC led to dramatically different regions of hypoxia.…”

“…In the Congo River for example, TA is flow-dependent but DIC is persistently high year-round (Wang et al, 2013). On top of natural variability, many estuaries also experience heavy anthropogenic pressure (Frankignoulle et al, 1996;Zhai et al, 2007;Cai et al, 2017), making them particularly vulnerable to ocean acidification (Cai et al, 2011 and in some cases the subject of intensive management and policy initiatives (Fennel et al, 2013).…”
