O 2 concentrations in the ocean have decreased since the 1980s. [2] Part of this decrease is due to increased ocean heat content (OHC) from global warming decreasing O 2 solubility. As solubility in surface oceans decreases, O 2 out gasses to the atmosphere. [3] Increased AOU is likely also contributing to declining ocean O 2 concentrations. [2]
The "saturation system", "saturation complex" or "saturation spread" typically comprises either an underwater habitat or a surface complex which includesof a living chamber, transfer chamber and submersible decompression chamber, [45] which is commonly referred to in commercial diving and military diving as the diving bell, [46] personnel ...

The lysocline is the depth in the ocean dependent upon the carbonate compensation depth (CCD), usually around 5 km, below which the rate of dissolution of calcite increases dramatically because of a pressure effect. While the lysocline is the upper bound of this transition zone of calcite saturation, the CCD is the lower bound of this zone. [1]
In OMZs oxygen concentration drops to levels <10 nM at the base of the oxycline and can remain anoxic for over 700 m depth. [7] This lack of oxygen can be reinforced or increased due to physical processes changing oxygen supply such as eddy-driven advection, [7] sluggish ventilation, [8] increases in ocean stratification, and increases in ocean temperature which reduces oxygen solubility.
Saturation (magnetic), the state when a magnetic material is fully magnetized; Saturated fluid or saturated vapor, contains as much thermal energy as it can without boiling or condensing Saturated steam; Dew point, which is a temperature that occurs when atmospheric relative humidity reaches 100% and the air is saturated with moisture
In medicine, oxygen saturation refers to oxygenation, or when oxygen molecules (O 2) enter the tissues of the body. In this case blood is oxygenated in the lungs, where oxygen molecules travel from the air into the blood. Oxygen saturation ((O 2) sats) measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen ...
A change in pH by 0.1 represents a 26% increase in hydrogen ion concentration in the world's oceans (the pH scale is logarithmic, so a change of one in pH units is equivalent to a tenfold change in hydrogen ion concentration). Sea-surface pH and carbonate saturation states vary depending on ocean depth and location.
