The age and origin of the central Scotia Sea [PDF]
, 2010 Opening of the Drake Passage gateway between the Pacific and Atlantic oceans has been linked in various ways to Cenozoic climate changes. From the oceanic floor of Drake Passage, the largest of the remaining uncertainties in understanding this opening is

The Age and Composition of the Voyager Seamounts: Evidence for a Long‐Lived Marquesas Mantle Source
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract We present new observations on the dynamics and locations of deep mantle reservoirs derived from the ages and compositions of Voyager Seamount Chain lava flows. The previously unexplored Voyager Seamount Chain trends NW–SE between the Mid‐Pacific Mountains and the Northwestern Hawaiian Ridge.

Crustal Structure Across the Okavango Rift, Botswana: The SEISORZ Wide‐Angle Seismic Experiment
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract The Okavango Rift Zone (ORZ) is an incipient continental rift in Botswana at the terminus of the Southwestern Branch of the East African Rift System. The lack of syn‐rift magmatism and tectonic processes overprinting pre‐rift structures provide an opportunity to investigate incipient‐stage rift processes and the role of pre‐existing structures

Lithospheric long-wavelength magnetic anomalies and their geological origins: A review
地球与行星物理论评At the altitude of low-Earth-orbiting satellites, most details of lithospheric magnetic anomalies observed near surface are attenuated, and only slowly decaying long-wavelength magnetic anomalies can be detected.

Space Weather, Volume 24, Issue 1, January 2026.Abstract Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks. It is often difficult to obtain transformer GIC data so ground based magnetometer data may be used to estimate the transformer GIC via complex modeling of both network and ...

Report of the panel on geopotential fields: Magnetic field, section 9 [PDF]
The objective of the NASA Geodynamics program for magnetic field measurements is to study the physical state, processes and evolution of the Earth and its environment via interpretation of measurements of the near Earth magnetic field in conjunction with

Space Weather, Volume 24, Issue 1, January 2026.Abstract Ionospheric radial currents (IRC) can be derived using two methodologies: (a) the single‐satellite approach: Single‐IRC is deduced from magnetic field data of a single satellite (Swarm‐A); (b) the dual‐satellite approach: Dual‐IRC is calculated by coordinated magnetic field measurements of a pair of satellites (Swarm‐A and ‐C).

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract The Newer Volcanic Province (NVP) in southeastern Australia is a classic example of continental intraplate volcanism located far from a plate boundary, yet the configuration of its magma plumbing system remains unclear. Using three‐dimensional (3D) magnetotelluric (MT) inversion, we imaged a vertically continuous, trans‐lithospheric conductive
