Reviews of Geophysics, 1995
This Quadrennial Report departs in format from its predecessors. Earlier reports provided brief descriptions of the entire range of topics on “crustal magnetic anomalies.” Following guidelines established by the AGU, we instead focus our discussion on only a few selected topics. Our abbreviated list of references reflects this restricted focus.

Reviews of Geophysics, 1979
Marine magnetic data have been available for many years from all of the world's oceans, and their contribution to marine geophysics and geology is profound. These data, for example, have allowed charting the age of the ocean floor, reconstruction of the geologic history of the major ocean basins, development of a Cenozoic and Mesozoic timescale of ...

Reviews of Geophysics, 1983
Without a doubt, the main event concerning the study of magnetic anomalies to have happened during this quadrennium was the successful deployment of a low elevation satellite which measured the scalar and vector magnetic field of the Earth. This satellite, called MAGSAT, was launched from Vandenberg Air Force Base on October 30, 1979 into a twilight ...

Abstract Extensive magnetic surveys have been made over the Arctic Ocean since 1946. The survey techniques have varied, as have the methods and forms of data presentation. This chapter reviews the magnetic anomaly information from the Arctic Ocean region and discusses the significant contributions made by magnetic surveys to the ...

MAGNETIC ANOMALIES OF CYLINDERS
The Quarterly Journal of Mechanics and Applied Mathematics, 1990Summary: It is well known that a semi-infinite cylinder with constant polarization has an enhanced magnetic anomaly near the rim. When susceptibility effects are negligible, the enhanced reading may be attributed to a logarithmic singularity. This logarithmic behaviour is also the reason why an orthogonal expansion is not likely to work satisfactorily ...

Continental magnetic anomalies
Reviews of Geophysics, 1979The mapping and interpretation of magnetic anomalies provide a useful and efficient method of studying crystalline basement rocks, igneous intrusions, and extrusive rocks of the continental crust. Accordingly, government, academic, and industrial efforts have been expended during the past four years in acquiring and interpreting new data, re ...

The East Coast Magnetic Anomaly
Science, 1984A model is proposed for the East Coast Magnetic Anomaly that, for the first time, incorporates an observed basement feature—a normal fault that consistently lies below the landward flank of the anomaly. The East Coast Magnetic Anomaly is similar to slope anomalies found over passive continental margins in many parts of the world.

Magnetic resonance of vascular anomalies
Magnetic Resonance Imaging Clinics of North America, 2002More than half of the patients with vascular anomalies referred to the Vascular Anomalies Clinic at Children's Hospital, Boston, have been misdiagnosed. A major consequence of misdiagnosis is inappropriate treatment, including deferral of necessary treatment and inappropriate use of pharmacotherapy, radiation, surgery, and embolotherapy.

Plasma Acceleration Above Martian Magnetic Anomalies
Science, 2006Auroras are caused by accelerated charged particles precipitating along magnetic field lines into a planetary atmosphere, the auroral brightness being roughly proportional to the precipitating particle energy flux. The Analyzer of Space Plasma and Energetic Atoms experiment on the Mars Express spacecraft has made a detailed study of acceleration ...

Characteristics Analysis of Magnetic Anomaly Signals in Airborne Magnetic Anomaly Detection
Proceedings of the 2017 2nd International Conference on Communication and Information Systems, 2017A high sensitivity optical pumping magnetometer is used to detect the magnetic anomaly signal in the space generated by a ferromagnetic target for the airborne magnetic anomaly detection system. Since the features of magnetic anomaly signals of the target at high altitude are less known, the detection distance of the traditional airborne magnetic ...
