Ground-penetrating radar

ground penetrating radargeoradarGPR
It employs a geophysical method similar to ground-penetrating radar that operates at frequencies in the MF, HF and VHF portions of the radio spectrum.
In the Earth sciences it is used to study bedrock, soils, groundwater, and ice.

Raymond Effect

Disturbances in these reflections that are unrelated to bedrock topography can be used to understand past ice flow, for example the anticlines arising from the Raymond Effect.
The stratigraphy is detected by radio-echo sounding.

Glacier

Radio frequency

It employs a geophysical method similar to ground-penetrating radar that operates at frequencies in the MF, HF and VHF portions of the radio spectrum. The conductivity of ice is small at radio frequencies, so its dielectric absorption is also small.

Permittivity

dielectric permittivitydielectric functionelectric permittivity
Glaciers are well suited to investigation by radar because the imaginary part of the permittivity of ice is small relative to its real part; this ratio is called the loss tangent. The conductivity of ice is small at radio frequencies, so its dielectric absorption is also small.

Boundary value problem

The primary goal of many radioglaciological surveys is to measure the thickness of a body of ice, which is an important boundary condition for ice-flow models.

East Antarctica

Ice thicknesses greater than 4 km have been measured in East Antarctica.

Reflection (physics)

Internal reflections have also been detected in many alpine glaciers and all modern ice sheets.

Stratigraphy

These layers represent the internal stratigraphy and can also be used to constrain ice-flow models.

Bedrock

The shapes of these internal reflections generally follow the bedrock topography and they are often assumed to be isochronous.

Antenna (radio)

Ice-penetrating radar systems, particularly the antennae, are often homemade systems made of commercially available components.

Firn

firn linefirn fieldfirnbedeckten
In the firn and at depths where densification is occurring, small changes in density alter the real part of the permittivity, which can cause reflections. Once densification is complete, changes in density in an ice column are not expected to be large enough to cause radar reflections.
