Holocene Glacial–Paraglacial–Periglacial Transitions of a Sub‐Arctic Glacial Cirque, Fremri‐Grasárdalur, Northern Iceland

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 78-106, January/March 2026.
ABSTRACT The aim of this work is to study a variety of glacial, periglacial and paraglacial features found in a small cirque, Fremri‐Grasárdalur, in Tröllaskagi (Northern Iceland). We implement a multidisciplinary approach combining high‐resolution geomorphological mapping, horizontal/vertical boulder displacement (from 1994 to 2019) and surface ...

Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

Geomagnetic field variability: geomagnetic dynamo and helical distributed chaos

, 2020
It is shown that helicity dynamics dominates the thermal convection-driven geomagnetic field variability. The notion of the distributed chaos has been used for this purpose. The large-scale circulation in the Earth's outer (metallic liquid) core is especially sensitive to the helicity dynamics and its chaotic reversals can be associated with the ...

Accurate and Robust Sensing of the Ionosphere With Uncoded Long Pulse ISR Measurements: 2. Differential Drift Inversions Using Lag Profile Phase Data

Radio Science, Volume 61, Issue 1, January 2026.
Abstract A method of estimating heavy (O+) and light (H+ and He+) ion drift velocities in the topside F‐region ionosphere using Arecibo uncoded long pulse data is presented. We show that multi‐ion drift velocity estimation using long pulse ACF phase data requires accurate knowledge of ionospheric state parameters, such as temperatures and compositions,

Accelerometer Data Transplant for Future Satellite Gravimetry

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Accurate monitoring of the Earth's gravity field is crucial for understanding mass redistribution processes related to climate change, hydrology, and geodynamics. The Gravity Recovery and Climate Experiment (GRACE) and its successor, GRACE Follow‐On (GRACE‐FO), have provided invaluable satellite gravimetry data through low‐low satellite‐to ...
