Geomagnetic Variability in a Post‐Superchron Geodynamo: Insights From the Deccan Traps

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Studying long‐term geomagnetic field behavior is crucial for understanding Earth's evolution, as field variability reflects processes in the planet's deep interior. One key question concerns the relationship between field strength and polarity reversal frequency, particularly during the Cretaceous Normal Superchron (CNS), a prolonged interval ...

Deep Water Renewal in the Amerasian Basin Derived From Natural and Anthropogenic Tracer Data Sets

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract The deep waters of the Amerasian Basin in the Arctic Ocean are among the most isolated in the modern Arctic Mediterranean Sea (e.g., Schlosser et al., 1997, https://doi.org/10.1016/s0168‐583x(96)00677‐5). In this study, we use a suite of tracers spanning a range of timescales—including chlorofluorocarbons (CFCs), SF6, radiocarbon (14C), and ...

Short‐Term Effect of Mars‐Like Radiation on Carbon and Oxygen Isotope Compositions of Carbonates

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The stable isotope composition of carbonates records the environmental formation conditions and can indicate potential biosignatures if formed biologically. Martian meteorite carbonates display unusually high δ13C values, not explained using known terrestrial processes.

The Chinese Radio Telescope Array for Interplanetary Scintillation Monitoring

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Solar flares, coronal mass ejections (CMEs) and enegertic particles, etc., are the driving sources that may cause catastrophic space weathers. It is desirable to obtain information of solar eruptions like flares and CMEs, etc., propagating from the Sun to the near‐Earth space.
