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 ...

Monitoring and Modeling the Soil‐Plant System Toward Understanding Soil Health
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

Climate and Hydrogeological Controls on Water Tracks in Permafrost Landscapes
Abstract Climate change drives disturbance in hydrology and geomorphology in terrestrial polar landscapes underlain by permafrost, yet measurements of, and theories to understand, these changes are limited. Water flowing from permafrost hillslopes to channels is often modulated by water tracks, zones of enhanced soil moisture in unchannelized ...

Wetlands are vital for humanity and include some of the most productive, diverse, and service‐rich ecosystems in the world. Service provided include food production (e.g., fish, birds, and vegetables), protection from flooding and storm surge inundation, provision of clean water and climate stability, and timber resources for construction.

Ecohydrogeological processes in tropical volcanic mountains are not well understood. We combined a quantitative water balance analysis in Google Earth Engine with qualitative interpretation of the study area's geologic and geomorphic features.

Ice-rich (periglacial) vs icy (glacial) depressions in the Argyre region, Mars: a proposed cold-climate dichotomy of landforms [PDF]
On Mars, so-called “scalloped depressions” are widely observed in Utopia Planitia (UP) and Malea Planum (MP). Typically, they are rimless, metres- to decametres-deep, incised sharply, tiered inwardly, polygonised and sometimes pitted.

Hollows on Mercury: Global Classification of Degradation States and Insight Into Hollow Evolution
Abstract Hollows are small, shallow, irregularly shaped landforms, widespread across Mercury, interpreted to have formed via loss of volatiles. Here, we present the first global analysis of hollow degradation states using a new machine learning‐derived global catalog.

The spatial distribution of rock landforms in the Pohořská Mountains (Pohořská hornatina), Czech Republic [PDF]
Geomorphological mapping with an emphasis on rock landforms was carried out in the Pohořská Mountains (Cz. Pohořská hornatina) and the positional data acquired were further processed using statistical and cartographical methods.

Comparison of Different Methods of Automated Landform Classification at the Drainage Basin Scale: Examples from the Southern Italy [PDF]
In this work, we tested the reliability of two different methods of automated landform classification (ACL) in three geological domains of the southern Italian chain with contrasting morphological features.

Evaluation of the impact of climate change on rainfall for potential landslide triggering in Japan
Under the scenario that future greenhouse gas emissions will continue to increase, the projection of precipitation in Japan until 2,100 suggests that intense rainfall with landslide‐triggering potential might increase and occur synchronously in two to five regions owing to more frequent and widespread occurrence of precipitation.
