Earth: Oceans
Ocean layer in which temperature decreases rapidly with depth. From 200 to 1000 meters the temperature decreases by 15 degrees F. In summer the thermocline becomes thin and gradients of 1 degree per foot can be observed.
P(Bar) = 981 cm/s2 * 12*2.54 * Z(ft) * (gm/cm3) * 1.0E-6 Bar/(dyn/cm2)
P(Bar) = 31.0 * Z(1000 ft)
Z(ft) | (gm/cm3) |
0 | 1.028 (assume 35 parts-per-thousand salinity) |
1000 | 1.033 |
2000 | 1.0375 |
20000 | 1.071 |

320 | 10 Bar |
3,200 | 100 Bar |
3,790 | 120 Bar <Z> of all Oceans - depth of life Zone |
4,690 | 145 Bar depth of Mediterranean |
7,282 | 225 Bar depth of Gulf of Mexico |
20,000 | 600 Bar max. depth of Atlantic |
35,600 | 1100 Bar 1960 depth of Trieste into Chall.II (7 miles!!) |
