TOPEX/Poseidon: Revealing Hidden Tidal Energy DLESE Reviewed Collection

Comment on this resource
Until recently, the total energy imparted to the oceans from the moon's gravitational pull has not been fully accounted for: about 30 percent had seemingly vanished without mathematical explanation. The total energy dissipating along the world's shallow areas and coasts don't add up to the expected total. However, data collected by the U.S./French satellite called TOPEX/Poseidon may provide the answer. Visualizations and remote imagery accompanied by text explain how the rough terrain of undersea mountains and ridges may dissipate the unaccounted-for energy.
