The project features three strategically-defined latitudinal swaths that cover some critical physiographic and geologic boundaries. The aim is to identify not only the range of geologically recent, ice-related landforms, but also their association with subtly-expressed geological units.\u00a0 <\/span>We present preliminary results for the Arcadia Planitia study area: a 250 km wide strip centred on -170\u00b0 longitude. We have used CTX (5-6 m\/pixel) and HRSC (colour and nadir, ~12.5-50 m\/pixel) images for the majority of the mapping, supported by higher resolution HiRISE (25 cm\/pixel) and MOC (~2 m\/pixel) images. We present our preliminary findings on the spatial distribution of landforms thought to be indicative of ground-ice in the regolith and the types of materials in which these forms occur.<\/p>\n","protected":false},"excerpt":{"rendered":" \u00a0Martian Cryosphere Workshop |Wroz\u0142aw | 10-12 February 2014 Mapping the northern plains of Mars: origins, evolution and response to climate change.
