5E also highlights the MOURA potential as
gradiometer.
The MEG system has 306 sensors grouped in triplets consisting of 2 planar
gradiometers and 1 magnetometer distributed at 102 locations.

Due to the new observable provided by the GOCE
gradiometer instrument (Rummel, 2010) the significant contribution of GOCE to the development of GGMs is expected in the spectral range of 100 to 250 d/0.
The group was awarded funding from the university to purchase a fluxgate
gradiometer to conduct the survey.
Four primary approaches are typically used to measure depth of soil cover over an existing pipeline: a) physical probing from the water surface or by diver, b)
gradiometer array, c) pulse induction system, and d) chirp subbottom profiler.

gradiometer program of the Geological Society of Canada.
North South Polar employed the latest in GPR technology, a
gradiometer, remote micro-camera technology and an innovative non-invasive hot water boring device.
Common sensors for field based archaeological applications include proton precession, cesium vapour and fluxgate configured in single,
gradiometer or multiple configurations, the relative utility of which are well summarised by Aspinall et al.
A
gradiometer is an array that is optimized to perform wave gradiometry, and typically has an aperture of less than 10% of the wavefield's central wavelength.
Magnetometry, either in single sensor or
gradiometer mode, has a long history of use in European and North American archaeology (e.
However, HSARPA is putting its money into an airborne
gradiometer, which can measures slight anomalies in slopes or earth.
