Drilling Within the Critical Zone

Hydrological Processes, Volume 40, Issue 3, March 2026.
This review synthesises 30 years of critical zone drilling methodologies for studying subsurface weathering, water storage, and biogeochemical processes. We evaluate drilling techniques, sampling strategies, downhole logging, and long‐term monitoring approaches while addressing contamination control and core preservation challenges.

Surface Enhanced Resonance Raman Spectra of a Model Molecule for Boron Dipyrromethene Dyes

Journal of Raman Spectroscopy, Volume 57, Issue 3, Page 427-430, March 2026.
Resonance Raman spectra of a model molecule for boron dipyrromethene dyes were obtained through a judicious choice of the sample and the measurement conditions, including excitation at 442 nm. Both spectra at the solid state and surface‐enhanced spectra on dispersed silver nanoparticles are presented.

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

Photometric and Spectral Characterization of Spacecraft Materials With Application to Lunar Trailblazer

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract If a spacecraft loses contact with Earth, ground‐based observatories can collect observations to assist the recovery effort by providing information on spacecraft location and state. Optical observations converted to a light curve of spacecraft magnitude over time show the spin period and/or orientation of the spacecraft.

The Evolution of a Polar Cap Patch Into a Blob in the Nightside Ionosphere: Direct Observations of Multiple Blob Formation Mechanisms Acting Simultaneously on the Same Plasma

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract A polar cap patch was observed to exit the polar cap to become a blob as it entered the auroral oval on the nightside of the Earth under moderately quiet geomagnetic conditions (Kp = 3−). Auroral particle precipitation led to an increase in the electron density of the blob.

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

Journal 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 ...
