Gravitational Potential Energy Sinks in the Oceans
Gravitational potential energy (GPE) is lost during convective adjustment. Using monthly mean climatological datasets, the annual mean GPE loss due to convective adjustment in the world oceans is estimated at 0.24 TW. Conversion from the mean-state GPE to eddies GPE and kinetic energy (KE) is also estimated, using the commonly accepted Gent-McWilliams scheme. Our estimate is that about 1.1TW is...

The last 3.85 Gyr of Earth history have been divided into five stages. During stage 1 (3.85-2.45 Gyr ago (Ga)) the atmosphere was largely or entirely anoxic, as were the oceans, with the possible exception of oxygen oases in the shallow oceans. During stage 2 (2.45-1.85 Ga) atmospheric oxygen levels rose to values estimated to have been between 0.02 and 0.04 atm. The shallow oceans became mildl...
