WebBelow the oxygen minimum layer there is often an increase in dissolved oxygen at the greatest depths (Figures 5.4.1, 5.4.2). This bottom water is usually colder than the surface water and is under enormous pressure; as stated above, lower temperatures and higher pressure increase the solubility of dissolved gases. WebOxygen minimum zones (OMZs) are midwater regions of the ocean with hypoxic waters, where oxygen concentrations typically are < 0.5 ml L -1 (or about < 20mM).
