Quizplus · Accepted Answer

Lows in dissolved oxygen can occur in various marine environments: at the bottom of trenches due to decomposition and lack of circulation, in mid-water depths in the eastern parts of the Pacific Ocean due to specific oceanographic conditions, and in estuaries in summer due to increased temperatures and nutrient runoff leading to eutrophication.
