Crustal structure and rift flank uplift of the Adare Trough, Antarctica [PDF]

, 2005
The Adare Trough, located 100 km northeast of Cape Adare, Antarctica, represents the extinct third arm of a Tertiary spreading ridge between East and West Antarctica. It is characterized by pronounced asymmetric rift flanks elevated up to over 2 km above

Evaluation of the lithospheric magnetic field mapped by the first year of MSS-1 data

Earth and Planetary Physics
The MSS-1 satellite began mapping Earth’s magnetic field in November 2023. Here, we perform a preliminary assessment of the new information provided on Earth’s lithospheric magnetic field from the first 12 months of data from MSS-1.

A comprehensive model of Earth’s magnetic field determined from 4 years of Swarm satellite observations

Earth, Planets and Space, 2018
The European Space Agency’s three-satellite constellation Swarm, launched in November 2013, has provided unprecedented monitoring of Earth’s magnetic field via a unique set of gradiometric and multi-satellite measurements from low Earth orbit.

Multiscale Analysis of Bouguer Gravity Anomalies: Unveiling the Deep Structure of Eastern Himalayan Syntaxis Faults

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Eastern Himalayan Syntaxis (EHS), which is located at the southeastern edge of the Qinghai–Xizang Plateau, is a key region for understanding mountain‐building and subduction processes. Bouguer gravity anomalies derived from the Earth Gravitational Model 2008 free‐air anomaly data following topographic corrections, were analyzed.

Modeling the lithospheric magnetic field over France by means of revised spherical cap harmonic analysis (R‐SCHA) [PDF]

Journal of Geophysical Research: Solid Earth, 2006
We have recently proposed the revised spherical cap harmonic analysis (R‐SCHA) modeling technique. The new mathematical functions represent faithfully the spatial variations of potential fields in a restricted area. In this paper, we tackle the inverse problem and outline the efficiency of the new basis functions with respect to real magnetic data ...

New Cretaceous Paleomagnetic and Geochronologic Data From the Antarctic Peninsula: Constraints on the Pre‐Opening Tectonic Evolution of the Drake Passage

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.

Lithospheric magnetic variations on the Tibetan Plateau based on a 3D surface spline model, compared with strong earthquake occurrences

Earth and Planetary Physics
The National Geophysical Data Center (NGDC) of the United States has collected aeromagnetic data for input into a series of geomagnetic models to improve model resolution; however, in the Tibetan Plateau region, ground-based observations remain ...

Compatibility of high-altitude aeromagnetic and satellite-altitude magnetic anomalies over Canada [PDF]

, 2002
Results from equivalent-source distributions derived jointly from high-altitude (average 4 km) aeromagnetic and Magsat-derived (average 400 km) magnetic anomalies over Canada indicate that long-wavelength components (500–2500 km) in these fields are ...

Self‐Consistent Models of Earth's Mantle and Core From Long‐Period Seismic and Tidal Constraints

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Here we illustrate the use of parameterized models to address fundamental questions about Earth's mantle and core structure. For this, we invert a large set of normal‐mode center frequencies and quality (attenuation) factors, along with astronomic‐geodetic data, for the radial anelastic seismic structure of the Earth.

Morphological Evolution of Impact Craters and Associated Gravity Anomalies: New Perspectives From Numerical Modeling

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Hyper‐velocity impacts on planetary surfaces lead to impact craters whose morphology evolves due to exogenous factors such as atmospheric processes, as well as endogenous factors including tectonic and metamorphism. On Earth, erosion processes driven by climate (fluvial, aeolian, glacial processes) progressively erase these structures, or even
