Depositional History of the Otis Peak Formation, Western Fan, Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The Mars 2020 Perseverance rover mission spent ∼250 sols investigating the Otis Peak formation (OPfm), a sequence of rocks containing the youngest recorded interval of sediment deposition via aqueous activity on Jezero crater’s western fan. This study uses orbiter and rover observations to interpret the formation and emplacement history of the

Sediment‐Rich Flow Morphology and Stratigraphy as Records of Emplacement Pressures on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Abundant geologic evidence suggests that sediment transport by liquid water on Mars took place across a wide range of atmospheric pressures, from at least ∼100 mbar in the Noachian‐Hesperian to ∼7 mbar average of today. Because these low pressures do not occur naturally on Earth, experimental studies in Mars pressure chambers are required to ...

Contrasting Responses of Carbon Dioxide and Methane Fluxes Following Thermokarst Erosion Across Tundra‐Lake Interfaces in the Western Canadian Arctic

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 11, November 2026.
Abstract Erosion from ice‐rich permafrost thaw (“thermokarst”) alters tundra vegetation cover and soil moisture, and laterally transports organic material into lakes, altering net fluxes of carbon dioxide (FCO2), methane (FCH4), and nitrous oxide (FN2O).

Integration of Aerosol–Cloud Interactions With a Land‐Atmosphere Coupled Model in the Gray Zone

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract Clouds strongly impact net surface radiation, creating differential heating patterns, and trigger land breezes that in turn organize cloud development. These dial processes determine the location of persistent ecohydrological regimes at local scales. Aerosol–cloud interactions (ACI) directly impact the diurnal cycle of cloud optical depth, and

When GRACE Measures More Than Water: Geomorphic Mass Redistribution in Terrestrial Water Storage Trends

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract The Gravity Recovery and Climate Experiment and its Follow‐On missions (GRACE/GRACE‐FO) provide indirect estimates of regional‐scale water storage changes, albeit at a coarse resolution (∼300 km). Interpreting GRACE‐derived trends in geomorphically complex settings presents additional challenges. High rates of soil erosion, sediment transport,
