Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Visible spectra of the Enceladus particle plume and E ring contain evidence for a change in spectral slope around 0.5 μm. This feature can be seen in data obtained by both the Visual and Infrared Mapping Spectrometer and Imaging Science Subsystem onboard the Cassini Spacecraft, and is consistent with the slope change seen in the surface ...

Arctic Warming Suppressed by Remnant Glacial Ice Sheets in Past Interglacials
Geophysical Research LettersTime slice experiments for past interglacial climates of Marine Isotope Stage (MIS)1, MIS5e, and MIS11 are simulated using an atmosphere‐ocean‐vegetation coupled general circulation model with prescribed remnant ice sheet distributions. We examine Arctic

Sliding Relations for Glacier Slip With Cavities Over Three‐Dimensional Beds
Geophysical Research Letters, 2020 Results of glacier flow models and associated estimates of future sea level rise depend sensitively on the prescribed relation between shear stress and slip velocity at the glacier bed.

AI Based Velocity Calibration for Cassini's Cosmic Dust Analyzer (CDA)
Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract This paper presents a novel AI‐based velocity calibration method for the Cosmic Dust Analyzer (CDA) onboard the Cassini spacecraft, in particular for impacts on the large Impact Ionization Detector (IID). The legacy polynomial calibration function, derived from laboratory measurements at a dust accelerator facility, assigns a velocity ...

Natural Soils‐Based Oxidation Mitigates Methane Leakage From Integrity Compromised Legacy Wells
Geophysical Research LettersAn increasing number of legacy petroleum wells are reported to suffer integrity failure, releasing methane (CH4) into the subsurface and atmosphere. Subsurface released methane is reactively transported toward ground surface with a portion converted to ...

Sentinel‐1 Detects Firn Aquifers in the Greenland Ice Sheet
Geophysical Research Letters, 2020 Firn aquifers in Greenland store liquid water within the upper ice sheet and impact the hydrological system. Their location and area have been estimated with airborne radar sounder surveys (Operation IceBridge, OIB).

Enhanced Tidal Mixing Strengthened and Stabilized the AMOC During the Bølling–Allerød
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Proxy records indicate a robust Atlantic Meridional Overturning Circulation (AMOC) during the Bølling–Allerød (BA) interstadial, despite substantial meltwater discharge. Using ocean circulation simulations, we demonstrate that enhanced tidal mixing, sustained by lower‐than‐modern sea levels, significantly strengthens the BA AMOC and increases ...

Toward ghost imaging with cosmic ray muons [PDF]
, 2012 Optical ghost imaging exploits the correlation between two light beams to reproduce the image of a remote object without employing imaging optics or high-resolution detectors near the object. In this paper we propose and investigate the implementation of

Climate‐Induced Polar Motion: 1900–2100
Geophysical Research LettersIt has been demonstrated that the motion of the Earth's rotational pole with respect to the crust—termed polar motion—is increasingly influenced by barystatic processes, that is, continental‐ocean mass redistribution due to melting of polar ice sheets ...

Glacial Earthquakes and Precursory Seismicity Associated With Thwaites Glacier Calving
Geophysical Research Letters, 2020 We observe two (~MS 3) long‐period (10–30 s) seismic events that originate from the terminus of Thwaites Glacier, Antarctica. Serendipitous acquisition of satellite images confirm that the seismic events were glacial earthquakes generated during the ...
