Superocean

The energy involved is of a magnitude difficult to visualize; for each valve will then be releasing about 230,000 hp, the total for each group of six being equal to 1,380,000 hp, or the equivalent of seven superocean liners each of the same power capacity as that of the "Queen Mary.".

Reduced to its simplest scenario the earth appears to have consisted essentially of a single ‘‘supercontinent’’, Pangaea, surrounded by “‘superocean”’ Panthalassa in the late Paleozoic.

To study the evolution of world ocean from a single supercontinent and superocean 200 million years ago to the fragmented system we have today.

The main reason for interest in Jurassic sediments from the Pacific is that they chronicle the paleoenvironment of the Jurassic superocean, which covered two-thirds of the Earth at the time, but for which we have no direct record.

A single supercontinent, called Pangea, came into, existence, together with a single superocean called Panthalassa.
