The Age and Origin of Block Deposits in the Victorian Alps, Australia

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 3, Page 391-415, July/September 2026.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

A Transient Coastal Uplift Event Revealed by Pleistocene Marine Terraces Along the 2015 M8.3 Illapel Earthquake Rupture, Chile

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.

Deterministic Propagation of Suprathermal Ions Through the Heliosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The PEPSSI instrument onboard New Horizons is sampling the energy range that bridges pickup and suprathermal He+ ${\mathrm{H}\mathrm{e}}^{+}$ ions for the first time in the outer heliosphere. New Horizons repeatedly encountered structures beyond 30 au that we interpret as the spiral of a corotating interaction region (CIR) for an extended ...

Polychromatic Population of Bioluminescent Organisms in the Deep Pacific Ocean

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract We present a comprehensive study of deep‐sea bioluminescent organisms in the Cascadia Basin, Northeast Pacific Ocean, based on four years (2020–2023) of in situ measurements using STRings for Absorption length in Water instruments. Analysis of over 1.3 million camera images and continuous photomultiplier tube recordings revealed that ...

Iron‐Silicate Segregation Within a Convecting Magma Ocean via the Multiphase Thermal Lattice Boltzmann Method: Implication on Iron‐Silicate Mixing

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract During the late stages of planetary accretion, large differentiated impactors interacted with the Earth's magma ocean, producing clouds of iron droplets that sank and mixed with silicates. Using a novel fluid‐dynamic approach combining the Thermal and Rothman‐Keller multiphase Lattice Boltzmann Methods, we modeled the segregation of impactor ...
