Marine gas hydrates incorporate significant concentrations of natural gases in their cages, mostly methane, and also ethane, propane, CO2 and H2S. Some anthropogenic tracers dissolved in sea water, e.g. CFC-11 (CFCl3) and CFC-12 (CF2Cl2), also have appropriate molecular diameters to occupy the structure I gas hydrate cages. The ratio of CFC-11/12 in sea water is often used to calculate sea water's apparent age. If CFC-11 and 12 are incorporated into natural marine gas hydrates and the CFC-11 to 12 ratio in the gas hydrate differs only by a constant from the sea water ratio, then it could also be used to date sea floor and shallow sub-seafloor gas hydrates.
