Steady Collapse of Uranus' Exosphere After 1998 to the Present Decade

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Uranus' thermospheric temperature decreased from ∼800K in 1986 to ∼450K in 2022 as determined from observations of H3+ and H2 infrared emissions. Spitzer 2007 lower atmosphere observations do not emulate this cooling trend. Here we show that the atomic H Lyman ⍺ emission from the disk of Uranus observed by HST from 2011 to 2022 are not ...

New Constraints on the Calabrian Arc (Central Mediterranean) Geodynamics: High‐Resolution Imaging of Lithospheric and Upper Mantle Discontinuities From P and S Receiver Functions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and upper mantle discontinuities across the Calabrian Arc and Southern Tyrrhenian basin.

Ice Sheet Dynamics Drive Pronounced Changes in the Subsurface Freshwater‐Saltwater Interface

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Saltwater is migrating into freshwater aquifers globally with water quality and biogeochemical implications, yet saltwater intrusion in glaciated regions is sparsely investigated. Field observations suggest that groundwater head in glaciated systems is influenced by ice sheet forcings and provides evidence that seawater infiltrated into ...

Impacts of Mean State Ocean Heat Transport on Climate and Its Response to CO2 Forcing

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Simulations of the slab ocean configuration of the coupled Energy Exascale Earth System Model (E3SM) were used to isolate the role of poleward ocean heat transport (OHT) in shaping the climate and its response to CO2 forcing. Imposed changes to mean‐state OHT produce compensating changes in atmospheric heat transport (AHT) that are mediated by

Mirror Mode Mediated EMIC Wave Generation in the Magnetosheath

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves and mirror modes (MMs), both driven by ion temperature anisotropy, are commonly observed in planetary magnetosheaths. Conventional explanations for their co‐occurrence are largely based on linear instability theory in proton–electron plasmas, which requires comparable growth rates for the EMIC and MM ...
