Acceleration (differential geometry)

In mathematics and physics, acceleration is the rate of change of velocity of a curve with respect to a given linear connection.

See Gravity gradiometry and Acceleration (differential geometry)

Atom interferometer

An atom interferometer uses the wave-like nature of atoms in order to produce interference.

See Gravity gradiometry and Atom interferometer

Bathymetry

Bathymetry is the study of underwater depth of ocean floors (seabed topography), lake floors, or river floors.

See Gravity gradiometry and Bathymetry

Bedrock

In geology, bedrock is solid rock that lies under loose material (regolith) within the crust of Earth or another terrestrial planet.

See Gravity gradiometry and Bedrock

Bell Aircraft

The Bell Aircraft Corporation was an American aircraft manufacturer, a builder of several types of fighter aircraft for World War II but most famous for the Bell X-1, the first supersonic aircraft, and for the development and production of many important civilian and military helicopters.

Centripetal force

A centripetal force (from Latin centrum, "center" and petere, "to seek") is a force that makes a body follow a curved path.

See Gravity gradiometry and Centripetal force

Coordinate system

In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

See Gravity gradiometry and Coordinate system

Dimensional analysis

In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric current) and units of measurement (such as metres and grams) and tracking these dimensions as calculations or comparisons are performed.

See Gravity gradiometry and Dimensional analysis

Eotvos (unit)

The eotvos is a unit of acceleration divided by distance that was used in conjunction with the older centimetre–gram–second system of units (cgs).

See Gravity gradiometry and Eotvos (unit)

Fault (geology)

In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements.

See Gravity gradiometry and Fault (geology)

Gal (unit)

The gal (symbol: Gal), sometimes called galileo after Galileo Galilei, is a unit of acceleration typically used in precision gravimetry. Gravity gradiometry and gal (unit) are gravimetry.

Gravimetry

Gravimetry is the measurement of the strength of a gravitational field. Gravity gradiometry and Gravimetry are Geodesy.

Gravitational acceleration

In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag). Gravity gradiometry and gravitational acceleration are gravimetry.

See Gravity gradiometry and Gravitational acceleration

Gravitational anomaly

In theoretical physics, a gravitational anomaly is an example of a gauge anomaly: it is an effect of quantum mechanics — usually a one-loop diagram—that invalidates the general covariance of a theory of general relativity combined with some other fields.

Gravity Field and Steady-State Ocean Circulation Explorer

The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) was the first of ESA's Living Planet Programme heavy satellites intended to map in unprecedented detail the Earth's gravity field.

Gravity of Earth

The gravity of Earth, denoted by, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). Gravity gradiometry and gravity of Earth are Geodesy.

Inverse second

The inverse second or reciprocal second (s−1), also called per second, is a unit defined as the multiplicative inverse of the second (a unit of time).

Kimberlite

Kimberlite, an igneous rock and a rare variant of peridotite, is most commonly known to be the main host matrix for diamonds.

Lockheed Martin

The Lockheed Martin Corporation is an American aerospace and defense manufacturer with worldwide interests.

Magnetic flux quantum

The magnetic flux, represented by the symbol, threading some contour or loop is defined as the magnetic field multiplied by the loop area, i.e..

Meissner effect

The Meissner effect (or Meißner–Ochsenfeld effect) is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state when it is cooled below the critical temperature.

See Gravity gradiometry and Meissner effect

Reef

A reef is a ridge or shoal of rock, coral, or similar relatively stable material lying beneath the surface of a natural body of water.

See Gravity gradiometry and Reef

Salt dome

A salt dome is a type of structural dome formed when salt (or other evaporite minerals) intrudes into overlying rocks in a process known as diapirism.

Scalar (physics)

Scalars (or scalar quantities) are physical quantities that are unaffected by changes to a vector space basis (i.e., a coordinate system transformation).

See Gravity gradiometry and Scalar (physics)

Spatial gradient

A spatial gradient is a gradient whose components are spatial derivatives, i.e., rate of change of a given scalar physical quantity with respect to the position coordinates in physical space.

See Gravity gradiometry and Spatial gradient

Superconductivity

Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic fields are expelled from the material.

See Gravity gradiometry and Superconductivity

Tensor

In mathematics, a tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space.

See Gravity gradiometry and Tensor

Tidal acceleration

Tidal acceleration is an effect of the tidal forces between an orbiting natural satellite (e.g. the Moon) and the primary planet that it orbits (e.g. Earth). Gravity gradiometry and tidal acceleration are Geodesy.

Unit of measurement

A unit of measurement, or unit of measure, is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

Water column

The (oceanic) water column is a concept used in oceanography to describe the physical (temperature, salinity, light penetration) and chemical (pH, dissolved oxygen, nutrient salts) characteristics of seawater at different depths for a defined geographical point.
