Assessing Potential Landing Sites With Favorable Illumination and Accessible, Potentially Volatile‐Rich Permanently Shadowed Regions Within Artemis Candidate Landing Regions

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...

Monitoring Flood Inundation Dynamics From Space

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

Surface elevation changes on Lachman Crags ice caps (north-eastern Antarctic Peninsula) since 1979 indicated by DEMs and ICESat data

open access: yesJournal of Glaciology, 2019
The long-term warming on the Antarctic Peninsula in the second half of the 20th century prompted rapid retreat of glaciers on the peninsula and surrounding islands.

Influences of Structural and Species Diversity on Forest Resistance to Drought

open access: yesEcology Letters, Volume 29, Issue 3, March 2026.
Forest structural richness and species evenness respectively show positive and negative relationships with forest resistance to drought. These relationships between richness and resistance and between evenness and resistance become stronger under more severe droughts.

Self‐Consistent Models of Earth's Mantle and Core From Long‐Period Seismic and Tidal Constraints

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Here we illustrate the use of parameterized models to address fundamental questions about Earth's mantle and core structure. For this, we invert a large set of normal‐mode center frequencies and quality (attenuation) factors, along with astronomic‐geodetic data, for the radial anelastic seismic structure of the Earth.

Estimation of canopy structure and individual trees from laser scanning data [PDF]

open access: yes, 2012
During the last fifteen years, laser scanning has emerged as a data source for forest inventory. Airborne laser scanning (ALS) provides 3D data, which may be used in an automated analysis chain to estimate vegetation properties for large areas ...

Mass changes of the Antarctic Peninsula ice sheet and peripheral glaciers, 2007–2021 [PDF]

open access: yesThe Cryosphere
The Antarctic Peninsula (AP), encompassing the ice sheet and its peripheral glaciers, is a highly dynamic component of the cryosphere that disproportionately contributes to sea-level rise relative to its size.
