Abstract

Increasing atmospheric CO2 concentration due to human activities is responsible for global warming and ocean warming, the latter enhancing stratification and shoaling of the upper mixed layer (UML). This hinders the upward transport of nutrients from deeper layers, and also causes organisms dwelling in the UML to be exposed to increased doses of PAR and UV radiation (see the review by Gao et al. (2020) and literature therein). Reduced O2 solubility in seawater along with ocean warming leads to ocean deoxygenation and rapid expansion of hypoxic zones in nearshore waters, where human nutrient over-enrichment can deplete dissolved oxygen by promoting excessive levels of primary production and consequent elevated bacterial respiration as that organic matter is broken down.
