Aeromagnetic map compilation: procedures for merging and an example from Washington

Annals of Geophysics, 2000
Rocks in Antarctica and offshore have widely diverse magnetic properties. Consequently, aeromagnetic data collected there can improve knowledge of the geologic, tectonic and geothermal characteristics of the region.

Geochemical Analysis of Diachronous V‐Shaped Ridges and Troughs That Flank the Reykjanes Ridge South of Iceland

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract It is recognized that mantle plumes play a direct role in generating regional uplift and producing immense volumes of basaltic magmatism, both of which can influence paleoclimate. The Icelandic Plume, beneath the North Atlantic Ocean, is of particular importance due to its size and position at a significant paleoceanographic gateway.

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

Earth 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.

Late‐Stage Rift Evolution at Back Arc Basins: Insights From a Tomography Experiment at Orca Volcano, Bransfield Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Back‐arc basins provide insights into the processes governing the evolution of continental rifting to seafloor spreading. The Bransfield basin hosts a back arc rift that is hypothesized to be in the late stages of this transition. Orca volcano is a submarine volcano that lies on the most evolved portion of the rift.

An Aeromagnetic Compensation Algorithm Based on a Temporal Convolutional Network

Applied Sciences
Aeromagnetic compensation is the main method for eliminating magnetic interference on flight platforms. With the improved sensitivity of aeromagnetic sensors, the generalization and compensation accuracy of existing aeromagnetic compensation methods have

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

Journal 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 ...

Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

Tectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Aeromagnetic data workshop

Eos, Transactions American Geophysical Union, 1983
A workshop on aeromagnetic data, sponsored by the National Geophysical Data Center (NGDC) of the National Oceanic and Atmospheric Administration, was held in Boulder, Colo., November 16–18, 1982, to evaluate the requirements for a national aeromagnetic database. The following recommendations were developed by J . R.

Regional Three‐Dimensional Magnetotelluric Electrical Resistivity Model of the Manica Greenstone Belt, Western Mozambique

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Magnetotelluric (MT) survey results from the Late Archean Manica greenstone belt, an extension of the Odzi‐Mutare greenstone belt of the Zimbabwe Craton, are presented. A total of 33 MT stations were acquired on an irregular grid with an average station spacing of approximately 5 km.

Technical procedures for aeromagnetic surveys in Antarctica during the Italian expeditions (1988-1992)

Annals of Geophysics, 1994
For most of Antarctica, the geophysical data now available are those of aeromagnetic surveys performed there from 1950 to 1960. Until 1984, the inaccurate positioning and insufficient monitoring of geomagnetic time variations allowed the investigation of
