Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

open access: yesEarth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.

Putative Analogs of Pyrite Suns Forming in Proglacial Alaska Mudflats

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Disc‐shaped pyrite suns of the Pennsylvanian age Anna Shale are thought to have formed where pressure restricted pyrite crystal growth to a flattened disc shape during diagenesis at the Anna Shale and the underlying Herrin coal boundary.

Gas Permeability of Frozen Sediments: Implications for Modeling Gas and Water Transport in Permafrost

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract We measure the gas permeability of two permafrost sediments at a range of ice saturations and use van Genuchten‐Mualem equations to model the relative gas (krg) and water (krw) permeabilities of frozen sediments. We show that our frozen sediment krg data and model display the same functional form as frozen and unfrozen sediment krg data from ...

Weakening Processes in Carbonate‐Hosted Faults: Phyllosilicate Microlayers and Injections Along the Mattinata Fault (Southern Italy)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Micrometric phyllosilicate films along fault slip surfaces (SSs) can drastically reduce friction, yet they are unexpected in clay‐poor carbonate platforms. We inquire how a major carbonate‐hosted, seismogenic strike‐slip fault can develop weak slip interfaces and undergo dynamic weakening despite an intrinsically strong host rock.

Archives of impact: The politics of craters on Earth

open access: yesGeographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.
