Compensation Method for Diurnal Variation in Three-Component Magnetic Survey

open access: yesApplied Sciences, 2020
Considering that diurnal variation interferes with three-component magnetic surveys, which inevitably affects survey accuracy, exploring an interference compensation method of high-precision is particularly desirable. In this paper, a compensation method

Transform fault earthquakes in the North Atlantic: Source mechanisms and depth of faulting [PDF]

open access: yes, 1988
The centroid depths and source mechanisms of 12 large earthquakes on transform faults of the northern Mid-Atlantic Ridge were determined from an inversion of long-period body waveforms.

Robust Directional Analysis of Magnetic Microscopy Images Using Non‐Linear Inversion and Iterative Euler Deconvolution

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In paleomagnetism, bulk measurements of entire samples have traditionally been used to characterize remanent magnetization. While effective, this approach provides only a general directional estimate and cannot resolve spatial variability or magnetization at the grain scale.

An Adaptive Aeromagnetic Compensation Method Based on Local Linear Regression

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Aeromagnetic compensation plays an important role in airborne magnetic survey to eliminate the magnetic interference from the aircraft. However, the aeromagnetic compensation methods at present still cannot suppress the interference to the extremely low noise level of a high-sensitivity scalar magnetometer due to the common ...

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.

A compilation of new airborne magnetic and gravity data across Dronning Maud Land, Antarctica. [PDF]

open access: yes, 2007
The evolution of the South Atlantic region including the Weddell Sea and its adjacent areas is of crucialimportance for understanding the processes of the structure and tectonics of the Antarctic lithosphere, its relation to geodynamic processes ...

Evaluation of Aliasing in Aeromagnetic Surveys ‐ Update to Reid 1980 Analysis

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Regularly spaced magnetic anomaly surveys, consisting of parallel traverse lines and perpendicular (more widely spaced) tie lines, are routinely collected for multiple applications including geologic studies and, more recently, as reference for alternative magnetic navigation.

Subglacial Topography of Coats Land Records Post‐Gondwanan Landscape Evolution and Early Ice‐Sheet Behavior in East Antarctica

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The East Antarctic Ice Sheet (EAIS) formed circa 34 million years ago and now contains an ice volume equivalent to ∼52 m of global sea‐level rise. Although the EAIS is approximately in balance today, there is substantial uncertainty regarding the sensitivity of sectors underlain by low‐lying bed topography to future climate and ocean warming ...

Fractalness of land gravity data and residual isostatic anomalies map of Argentina, Chile and western Uruguay [PDF]

open access: yes, 2015
Gravity anomalies are often strongly influenced by topography, which effect is mitigated through appropriate reductions. Usually, a standard value of 2670 kg/m3 is used for the density of topography in the absence of specific information.
