Gridmapping the northern plains of Mars: Geomorphological, Radar and Water-Equivalent Hydrogen results from Arcadia Plantia [PDF]

, 2019
A project of mapping ice-related landforms was undertaken to understand the role of sub-surface ice in the northern plains. This work is the first continuous regional mapping from CTX (“ConTeXt Camera”, 6 m/pixel; Malin et al., 2007) imagery in Arcadia ...

Geogenic factors as drivers of microbial community diversity in soils overlying polymetallic deposits [PDF]

, 2015
This study shows that the geogenic factors landform, lithology, and underlying mineral deposits (expressed by elevated metal concentrations in overlying soils) are key drivers of microbial community diversity in naturally metal-rich Australian soils with

Pleistocene plateau ice fields in the High Atlas, Morocco [PDF]

, 2016
Large ice fields (>25 km² ) formed over the Tazaghart and Iouzagner plateaux of the High Atlas, Morocco, during the Late Pleistocene. The plateau ice fields were drained by large valley glaciers forming a series of moraine assemblages. Four moraine units

Morphology of Antarctic Polygons and Implications for Polygon Evolution and Subsurface Ice Dynamics

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 143-153, January/March 2026.
ABSTRACT Polygonal terrain results from thermal contraction, is commonly found in periglacial environments, and serves as a valuable proxy for interpreting subsurface ice distribution and climate history on Earth and Mars. In this study, we investigate the morphology of polygons in Beacon Valley, Antarctica, to assess the relationship between polygon ...

Characterization of a Lava Plain NW of Ascraeus Mons, Mars, Through Surface Morphometric Analyses and SHARAD Subsurface Detections

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The Martian lava plains are characterized by their extensive, low‐relief surfaces, which are the result of numerous basaltic eruptions and feature a variety of volcanic landforms, including vents, cones, pits, and skylights. The combination of these features and impact craters yields a significant understanding of the planet's geological past ...

Shallow landsliding and catchment connectivity within the Houpoto Forest, New Zealand. [PDF]

, 2013
Active landslides and their contribution to catchment connectivity have been investigated within the Houpoto Forest, North Island, New Zealand. The aim was to quantify the proportion of buffered versus coupled landslides and explore how specific physical

Creating a Critical Zone: Feedbacks Between Bedrock Geology, Water Retention, and Vegetation on an Exposed Bedrock Surface, Panola Mountain, Georgia, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.
Abstract Most of Earth's present‐day terrestrial surface is covered by regolith—the layers of soil, saprolite, and weathered bedrock that together comprise the critical zone. Recent research has focused on understanding fluxes of minerals, water, and energy through the critical zone under steady state assumptions.
