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… 
Significant dissipation of tidal energy in the deep ocean inferred from satellite altimeter data
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.

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
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
Tides on Other Earths: Implications for Exoplanet and Palaeo‐Tidal Simulations
A key controller of a planet's rotational evolution, and hence habitability, is tidal dissipation, which on Earth is dominated by the ocean tides. Because exoplanet or deep‐time Earth topographies
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

Paper on the creep tide theory and its applications to satellites and planets with emphasis on a new set of differential equations allowing easier numerical studies. The creep tide theory is a new
Tides—a modern perspective
Progress in tidal science has been rapid in recent years. The advent of precision altimetry has enabled, for the very first time in tidal history, an accurate measurement of tides in most of the

The most precise way of estimating the dissipation of tidal energy in the oceans is by evaluating the rate at which work is done by the tidal forces and this quantity is completely described by the
Planetary energy balance for tidal dissipation
Dissipation of tidal energy is expressed here as an integral on the surface of a sphere that encloses the mass of the planet. When developed in constituent form, this surface integral depends
Energetics of global ocean tides from Geosat altimetry
The authors' global ocean tide maps derived from Geosat altimetry are here improved in quality and coverage; they compare favorably with ground truth data at about the same rms level as Schwiderski's
The response of a realistic earth to ocean tide loading
SUMMARY A novel ocean tide loading model is developed which allows the earth to be self-gravitating, compressible, layered, anisotropic viscoelastic and rotating, with a solid inner core and fluid
Spectroscopy of the world ocean tides from a finite element hydrodynamic model
An atlas of the main components of the tides has been produced on the basis of a finite element hydrodynamic model, with the aim of offering the scientific community, using satellite altimetric data,
The effects of mantle anelasticity on nutations, earth tides, and tidal variations in rotation rate
Summary. We model the effects of mantle anelasticity on luni-solar nutations, on tidal deformation, on tidal variations in rotation rate, and on the eigenfrequency of the free core nutation. Our
A preliminary tidal analysis of TOPEX/POSEIDON altimetry
Approximately 12 months of data from the TOPEX/POSEIDON satellite altimeter mission are analyzed for the major short-period oceanic tides. A harmonic analysis is performed on data captured within

Intercomparison of recent ocean tide models
One of the tremendous achievements of the TOPEX/POSEIDON (T/P) satellite mission is the release of 12 new global ocean tide models during 1994. Virtually all of these models are based on the
