Modern Method of Aeromagnetic Survey
Proceedings, 2012Existing aeromagnetic survey method was improved by replacing plane to flying machine - Deltafly, which has low altitude (hight 3-5 m). Such work was tested in order to find out hydrocarbons' deposits in USSR in 1990th. However, the method was developed and improved by using GPS navigator, 2 magnetometers (MMPG-1 and MINIMAG, Russia).

Geophysics, 1980
Abstract Aeromagnetic surveys are flown with a wide variety of terrain clearances, sampling rates, and line spacings. The results are generally presented as contour maps, implying that the survey grid defines the continuous magnetic field sufficiently well to justify interpolation.

An aeromagnetic survey of the Norwegian Sea
Journal of Geophysical Research, 1968An aeromagnetic survey of the marine area from 20°E to 15°W and 60°N to 73°N has been completed. Total intensity and residual intensity contour charts show the presence of a linear magnetic pattern paralleling the mid-oceanic ridge in the Norwegian Sea. The aeromagnetic charts are supplemented by bathymetric and shipboard magnetometer data.

History of aeromagnetic surveying in Canada
The Leading Edge, 2007The first instrument to measure the magnetic field while being flown in an aircraft was the Earth inductor magnetometer. This was done in the USSR in 1936. But the system's sensitivity of 100 nT, called gammas in those days, was hardly suitable for routine surveys of large areas.

Aeromagnetic Surveys in the Seas Around Japan in 1980
Geophysical Surveys, 1984Aeromagnetic surveys in the seas around Japan were carried out in 1979 to 1980 by a YS-11 aircraft of the Maritime Safety Agency of Japan using a new type of airborne magnetometer system. The new type of airborne magnetometer system consists of a ring-core type three-component fluxgate magnetometer, an inertial sensing system, a fish-eye camera to ...

A NEW PARAMETER FOR AEROMAGNETIC SURVEYING*
Geophysical Prospecting, 1967ABSTRACTThe author proposes the parameter Δ2/ΔT1 for possible application in aeromagnetic surveying making use of already available gradiometer systems equipped with sensors separated vertically.

Gradient measurements in aeromagnetic surveying
Geophysics, 1965Abstract The recent development of highly sensitive magnetometers, such as the optical-pumping varieties, has made feasible the measurement of the first vertical derivative of the total field (delta Delta T/delta h) in aeromagnetic surveys. This is accomplished by using two sensitive magnetometer heads separated by a constant vertical

BLAKE RIDGE AEROMAGNETIC SURVEY
1967Abstract : Two positive magnetic lineations are revealed in an aeromagnetic survey of a 20,000 square mile area over the Blake Ridge. The two magnetic anomalies are generally parallel to the continental slope, but show no particular relation to the Blake Ridge which they cross at an angle of approximately 70 degrees.
