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. WebApr 1, 1998 · These oxygen minimum layers are areas of the water column and the associated benthos with stable conditions of continuously low oxygen level and low …
The oxygen minimum zone (OMZ), sometimes referred to as the shadow zone, is the zone in which oxygen saturation in seawater in the ocean is at its lowest. This zone occurs at depths of about 200 to 1,500 m (660–4,920 ft), depending on local circumstances. OMZs are found worldwide, typically along the … See more Surface ocean waters generally have oxygen concentrations close to equilibrium with the Earth's atmosphere. In general, colder waters hold more oxygen than warmer waters. As water moves out of the See more • Dead zone (ecology), localized areas of dramatically reduced oxygen levels, often due to human impacts. • Ocean deoxygenation See more Despite the low oxygen conditions, organisms have evolved to live in and around OMZs.
