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

open access: yes, 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]

open access: yes, 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

Soil surveys: A window to the subsurface [PDF]

open access: yes, 2005
Soils and underlying parent materials form a continuous system we must understand and manage in total. Numerous concerns (e.g., water quality, on-site waste disposal, landfill placement, and nutrient or pesticide movement) require an integrated knowledge

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

open access: yes, 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

Infiltration Dynamics on Early Mars: Geomorphic, Climatic, and Water Storage Implications

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract On early Mars, the integration of surface, groundwater, and climate systems into an integrated hydrological system remains poorly understood. The partitioning of precipitation, between surface and groundwater via infiltration, controls the Martian aquifer recharge rates and, subsequently, surface erosion processes.

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

open access: yes, 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

The origin of bedrock mega-grooves in glaciated terrain [PDF]

open access: yes, 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.
