A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

Analysis of High Frequency Marsquake Swarms Informed by Deep Learning

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract NASA's InSight mission has provided an unprecedented snapshot of Mars' seismicity, despite data analysis challenges arising from low signal‐to‐noise ratios (SNR) and single‐station constraints. High frequency (HF) events—the most common type—were initially assumed to propagate through shallow crustal layers.

Craters and Lunar Lua (Pits/Skylights) in Mare Tranquillitatis and Marius Hills Reveal Variations in Protolith Properties

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract We investigated the regolith parent rock (“protolith”) properties of Mare Tranquillitatis and Marius Hills on the Moon, utilizing lunar pit craters (“lua”) to contextualize observations of rock abundance and crater degradation. We discovered a significant difference in underlying materials: the region around the Tranquillitatis lua is ...

Slip‐Event Timing and Ice Velocity Vary at Long‐Period Ocean Tidal Frequencies at Whillans Ice Plain, West Antarctica

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.
Abstract Whillans Ice Plain (WIP), a region of West Antarctica flowing into the southern Ross Sea, lurches forward 0.2–0.6 m over 30–60 min once or twice per diurnal ocean tidal cycle. Combining 11 years (2008–2019) of 30 s or better resolution Global Navigation Satellite System (GNSS) data from past field campaigns is necessary to provide insight into

Biophysical Controls on Sediment Erodibility in Shallow Estuarine Embayments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract The erodibility of cohesive sediment is known to vary both spatially and temporally but the factors governing its variation are not well understood. We conducted a field investigation of the influence of hydrodynamic forcing, sediment properties, and benthic infauna on erodibility in the muddy shallows of San Pablo and Grizzly Bays in northern
