Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Morphology of the Excited Hydroxyl in the Martian Atmosphere: A Model Study—Where to Search for Airglow on Mars?

Remote Sensing
Monitoring excited hydroxyl (OH*) airglow is broadly used for characterizing the state and dynamics of the terrestrial atmosphere. Recently, the existence of excited hydroxyl was confirmed using satellite observations in the Martian atmosphere.

Data assimilation insights on selecting the most valuable atmospheric measurements [PDF]

, 2012
We discuss how objective guidance on selecting the most valuable atmospheric measurements on future Mars spacecraft missions can be provided through already developed Martian atmospheric data assimilation systems, and in particular through Observing ...

Oxychlorine Species on Mars: A Review

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Advective Fluxes in the Martian Regolith as a Mechanism Driving Methane and Other Trace Gas Emissions to the Atmosphere

Geophysical Research Letters, 2020
Advective fluxes influence methane and CO2 soil emissions into the atmosphere on Earth and may drive trace gas emissions in the Mars atmosphere. However, their relevance in the Martian regolith has not been evaluated to date.

The Usefulness of NotebookLM's Audio Overview for Planetary Scientists

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The availability and use of artificial intelligence (AI) tools has increased substantially in recent years. NotebookLM was released in 2023 and is an AI tool with the capability to generate text summaries of input material. In 2024, an “Audio Overviews” feature was released that can generate podcast‐style audio files of the summarized material.

Seasonally Dependent Formation of Sulfates in the Basque Lakes, British Columbia, as Analogous to “Cold and Wet” and “Warm and Wet” Mars

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Saline lakes are expected to have been extensively present on ancient Mars, particularly as the planet dried or cooled. Such lakes likely deposited sulfate salts, as these salts have been widely identified from orbital and in situ Mars data. However, the relationship between martian sulfates and the environmental conditions that formed them ...

Methods for Cleaning Apollo Passive Seismic Data

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Apollo passive seismic data provide a unique resource for studying the lunar interior structure. However, the raw data are frequently contaminated by various artifacts, either related to the seismic sensors and the acquisition system or to issues during data transmission to the Earth.
