Journal of Geophysical Research: Earth Surface, Volume 130, Issue 3, March 2025.Abstract This study investigates surface weathering and sediment preservation at Table Mountain, a high‐elevation, hyperarid, polar landscape in the Transantarctic Mountains. We report cosmogenic nuclide concentrations (10Be and 26Al) in quartz from bedrock surfaces, erratic boulder lag, and cobbles embedded within Sirius Group sediments to quantify ...

The origin of bedrock mega-grooves in glaciated terrain [PDF]
, 2022 Bedrock mega-grooves (BMGs) are large-scale bedrock corrugations reported from glaciated terrain across the world. They are remarkably straight, and closely parallel with ice-flow direction.

Monitoring and Modeling the Soil‐Plant System Toward Understanding Soil Health
Reviews of Geophysics, Volume 63, Issue 1, March 2025.Abstract The soil health assessment has evolved from focusing primarily on agricultural productivity to an integrated evaluation of soil biota and biotic processes that impact soil properties. Consequently, soil health assessment has shifted from a predominantly physicochemical approach to incorporating ecological, biological and molecular microbiology

Erosional development of bedrock spur and gully topography in the Valles Marineris, Mars [PDF]
Gully networks separated by resistant bedrock spurs are a common erosional feature along the escarpments that border the Valles Marineris. The resistant spur topography is best developed where the base of the slope is truncated by linear scarps ...

Methane release on Early Mars by atmospheric collapse and atmospheric reinflation [PDF]
, 2019 A candidate explanation for Early Mars rivers is atmospheric warming due to surface release of H$_2$ or CH$_4$ gas. However, it remains unknown how much gas could be released in a single event.

Martian geomorphology and its relation to subsurface volatiles [PDF]
Martian volatile inventory, planetary climatic and atmospheric evolution, and the interpretation of various remote sensing data were discussed. A number of morphologies that were cited as potential indicators of subsurface volatiles were reviewed ...

Lunar Observer Laser Altimeter observations for lunar base site selection [PDF]
One of the critical datasets for optimal selection of future lunar landing sites is local- to regional-scale topography. Lunar base site selection will require such data for both engineering and scientific operations purposes.
