[1] In this brief report we consider the possibility that the northern plains of Mars would today be a frozen ocean, covered by a rather thin (at most of the order of a few hundred meters) layer of volcanic and impact debris and dust that prevents the ice beneath from being directly observed and thermally protects it from summertime sublimation (according to current models, subsurface ice in the high latitudes is stable under current climatic conditions). The frozen ocean hypothesis would… Expand

Episodic flood inundations of the northern plains of Mars
Throughout the recorded history of Mars, liquid water has distinctly shaped its landscape, including the prominent circum-Chryse and the northwestern slope valleys outflow channel systems, and theExpand
Oceans, Lakes, and Stromatolites on Mars
Billions of years ago, the Northern Hemisphere of Mars may have been covered by at least one ocean and thousands of lakes and rivers. These findings, based initially on telescopic observations andExpand
Characterisation of Isidis Planitia and the Beagle 2 Landing Site on Mars
Isidis Planitia is a large impact basin on Mars. I have determined that the extensive numbers of sub-kilometre sized cones and cone chains in the basin are the result of deposition of sediments byExpand
Mars: Life, Subglacial Oceans, Abiogenic Photosynthesis, Seasonal Increases and Replenishment of Atmospheric Oxygen
Abstract The discovery and subsequent investigations of atmospheric oxygen on Mars are reviewed. Free oxygen is a biomarker produced by photosynthesizing organisms. Oxygen is reactive and on Mars mayExpand

Ice in the Martian regolith
A number of possible morphologic indicators of ground ice on Mars are discussed, with emphasis on rampart craters and terrain softening. Geologic evidence indicates that the Martian surface has beenExpand
A model for the hydrologic and climatic behavior of water on Mars
Past studies of the climatic behavior of water on Mars have universally assumed that the atmosphere is the sole pathway available for volatile exchange between the planet's crustal and polarExpand
The Evolution of the Martian Hydrosphere: Implications for the Fate of a Primordial Ocean and the Current State of the Northern Plains
Abstract In this paper we consider the hydraulic and thermal conditions that gave rise to the elevated source regions of the Late Hesperian outflow channels and explore their implications for theExpand
The Evolution of the Martian Hydrosphere and Its Implications for the Fate of a Primordial Ocean
The existence of a primordial ocean in the northern plains of Mars appears to have been an inevitable consequence of the hydraulic and thermal conditions that existed during the Early Noachian. InExpand
Coastal Geomorphology of the Martian northern plains
The paper considers the question of the formation of the outflow channels and valley networks discovered on the Martian northern plains during the Mariner 9 mission. Parker and Saunders (1987) andExpand
Possible ancient oceans on Mars: evidence from Mars Orbiter Laser Altimeter data.
High-resolution altimetric data define the detailed topography of the northern lowlands of Mars, and a range of data is consistent with the hypothesis that a lowland-encircling geologic contactExpand
Shape of the northern hemisphere of Mars from the Mars Orbiter Laser Altimeter (MOLA)
Eighteen proles ofN-S-trending topography from the Mars Orbiter Laser Altimeter (MOLA) are used to analyze the shape of Mars' northern hemisphere. MOLA observations show smaller northern hemisphereExpand

Retention of an atmosphere on early Mars
The presence of valley networks and indications of high erosion rates in ancient terrains on Mars suggest that Mars was warm and wet during heavy bombardment. Various processes that could occur onExpand
The early environment and its evolution on Mars: Implication for life
There is considerable evidence that the early climate of Mars was very different from the inhospitable conditions there today. This early climate was characterized by liquid water on the surface andExpand
