Trial airborne environmental and geological survey of target areas in the English Midlands [PDF]

open access: yes, 2000
A series of four trial airborne environmental and geological surveys was flown by the Geological Survey of Finland (GTK) in collaboration with the British Geological Survey (BGS) in June 1999; the trials were co-sponsored by the Department of the ...

Seismic properties of the crust and uppermost mantle of North America [PDF]

open access: yes
Seismic refraction profiles for the North American continent were compiled. The crustal models compiled data on the upper mantle seismic velocity (P sub n), the crustal thickness (H sub c) and the average seismic velocity of the crystalline crust (V sub ...

Seismic and aseismic deformation along the East African Rift System from a reanalysis of the GPS velocity field of Africa

open access: yes, 2013
International audienceThe improvement of the geodetic coverage within the African Plate over the last decade together with an extended GPS position time-series allows improved accuracy in determining the velocity field than prior geodetic studies.

Improving Aeromagnetic Calibration Using Artificial Neural Networks [PDF]

open access: yes, 2020
The Global Positioning System (GPS) has proven itself to be the single most accurate positioning system available, and no navigation suite is found without a GPS receiver. Even basic GPS receivers found in most smartphones can easily provide high quality

Automatic aeromagnetic compensation

open access: yes, 1979
Improvements to the CAE FACS algorithm for compensating aircraft magnetic interference are outlined and demonstrated using data collected with the NAE North Star aircraft. The aircraft interference model is shown to contain some inherent linear dependencies, or multicollinearities, among the independent variables, leading to inaccurate coefficient ...
