Will Earth-like planets be found to have Earth-like oceans?

For a planetary surface to boast extensive areas of both land and water, a delicate balance must be struck between the volume of water it retains and the capacity of its oceanic basins. Each of these two quantities may vary substantially across the full spectrum of water-bearing worlds. Why the Earth’s values are so well balanced is an unresolved and long-standing conundrum. In a paper published in the Monthly Notices of the Royal Astronomical Society (Ed. Oxford University Press) the author, Fergus Simpson of the Institute of Cosmos Science at the University of Barcelona, has constructed a statistical model – based on Bayesian probability – to predict the division between land and water on habitable exoplanets.

The Earth has oceans and continents: how weird is that?

For a planetary surface to boast extensive areas of both land and water, a delicate balance must be struck between the volume of water it retains, and the depth and height of its valleys and mountains. With too much water, sea levels will be above the highest point on the planet. But if a planet doesn't have enough water, it will be quasi-desert.
