Chemical evolution of the early Martian hydrosphere [PDF]

open access: yes
The chemical evolution of the early Martian hydrosphere is discussed. The early Martian ocean can be modeled as a body of relatively pure water in equilibrium with a dense carbon dioxide atmosphere. The chemical weathering of lavas, pyroclastic deposits,

Characterizing Ice-wedge Polygon Geomorphology in the Haughton Impact Structure, Devon Island [PDF]

open access: yes, 2018
Ice-wedge polygon networks are a common feature in periglacial environments formed through thermal contraction cracking and snowmelt infiltration. Polygons of similar morphology are ubiquitous throughout the mid-latitudes of Mars and are believed to have
