THE rate at which tidal energy is dissipated in the solid Earth can constrain the anelastic properties of the Earth at frequencies much lower than those accessible with seismology. The dissipative properties of a system are usually expressed as a 'quality factor', Q; estimates1–7 of the semi-diurnal solid-Earth Q range from 90 to 500. But observational constraints on this quantity are difficult to obtain, because dissipation by the body tide is masked by the much greater dissipation that occurs… Expand

Significant dissipation of tidal energy in the deep ocean inferred from satellite altimeter data
TLDR
Satellite altimeter data from Topex/Poseidon is used to map empirically the tidal energy dissipation and shows that approximately 1012 watts—that is, 1 TW, representing 25–30% of the total dissipation—occurs in the deep ocean, generally near areas of rough topography. Expand
Constraints on Energy Dissipation in the Earth's Body Tide from Satellite Tracking and Altimetry
The phase lag by which the earth's body tide follows the tidal potential is estimated for the principal lunar semidiurnal tide M(sub 2). The estimate results from combining recent tidal solutions… Expand
Scaling in global tidal dissipation of the Earth-Moon system
Abstract The Moon migrated to cm over a characteristic time r / v = 10  Gyr by tidal interaction with Earth’s oceans at a present velocity of v = 3.8  cm yr − 1 . We model global dissipation to cover… Expand
Estimates of M2 Tidal Energy Dissipation from TOPEX/Poseidon Altimeter Data
Most of the tidal energy dissipation in the ocean occurs in shallow seas, as has long been recognized. However, recent work has suggested that a significant fraction of the dissipation, perhaps 1 TW… Expand
Lunar rotational dissipation in solid body and molten core
Analyses of Lunar Laser ranges show a displacement in direction of the Moon's pole of rotation which indicates that strong dissipation is acting on the rotation. Two possible sources of dissipation… Expand
Tides on the Moon: Theory and determination of dissipation
Solid body tides on the Moon vary by about ±0.1 m each month. In addition to changes in shape, the Moon's gravity field and orientation in space are affected by tides. The tidal expressions for an… Expand
Determination of solid Earth tide phase lag by satellite observation data
The geopotential variation caused by solid Earth, ocean and atmospheric tides can be estimated from artificial satellite orbit perturbations. It is shown that the total tidal variation in… Expand
