Low-altitude palaeoglaciation in Atlantic mountain regions provides important insights into past climatic conditions and moisture dynamics during the Last Glacial Cycle. This study presents the first quantitative reconstruction of palaeoglaciers in Serra

ABSTRACT Building an understanding of river ecosystems often involves integrating information from different locations, spatial scales and points in time. Geomorphologists and ecologists have long considered ways to explore river ecosystems at different, hierarchical, spatial scales so that features observed locally can be linked to the character of ...

Diurnal Temperature Variability at Latitudinally Distinct Sites on the Moon
Abstract The thermophysical environment of the Moon plays a crucial role for future exploration, resource utilization and also in understanding its geological evolution. While global‐scale surface temperature distributions have been reasonably well constrained through numerical modeling and orbiter observations, recent in situ measurements have ...

Subterranean glacial spillways: an example from the karst of South Wales, UK [PDF]
Many karst areas in the UK have been glaciated one or more times during the last 0.5 Ma, yet there are few documented examples of caves in these regions being affected by glacial processes other than erosion.

Effectiveness of Ecosystem‐Based Coastal Defenses Against Flooding
Abstract Coastal flooding is growing substantially as storms increase and sea levels rise rapidly due to climate change. It is therefore important to find safe and sustainable ways to protect coastal communities against this growing risk. However, the effectiveness of traditional coastal defenses (hard seawalls) (HS) is being questioned due to concerns

Crater Retention Timescales of Brain Coral Terrain Record Past Climatic Change on Mars
Glacial landforms on Mars offer an opportunity to decipher the planet’s recent climate history. We used crater size frequency distributions of brain coral terrain on concentric crater fill, lobate debris aprons, and lineated valley fill, all of which ...

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.

Abstract Basin‐filling strata are Mars's historical record of depositional events, including sedimentation by alluvial rivers, and post‐depositional events, including tilting. Measuring stratal tilt on Mars could constrain post‐depositional processes, but is difficult to measure where exposures are 3D and lack clear stratal surfaces, as is often the ...

Abstract Abrupt permafrost thaw events are projected to contribute up to 40% of permafrost carbon (C) release to the atmosphere. They involve sudden hydrological shifts within the soil column; however, the exact microbial functional pathway shifts induced by these events remain cryptic. To investigate how C and nutrient cycling processes differ in thaw
