Which outcome occurs when a large phytoplankton bloom decays within a subtropical gyre?

💡 Explanation

Hypoxic zones expand due to the increased oxygen consumption via decomposition. Bacterial respiration is fueled by the bloom's organic material, therefore oxygen decreases significantly at depth, rather than increasing burial rates or affecting upwelling at the coast.
