This paper describe the ice-related landforms investigated within Danielson crater, a Martian deep crater which is centered at about 7°W and 8°N, in the region of southwestern Arabia Terra about 775 km south of Becquerel crater. A morphological and morphometric survey of the study area through an integrated analysis of the available Mars images was carried out. The morphological features of the landforms were analyzed through an integrated analysis of Reconnaissance Orbiter (MRO) High Resolution Imaging Science Experiment (HiRISE) and Context Camera (CTX) data. In addition, a DTM of the study area within the Danielson crater was built using two stereo pair HiRISE images. Different landforms interpreted as due to ice-related processes was observed in the study area. The landforms investigated resemble similarly ice-related landforms that can be observed both in the cold region on the Earth, and in other region of Mars. The analysis carried out seem to indicate the presence of landforms attributed to the presence of ground ice and ice-melting processes which can reflect significantly climatic changes and different climatic conditions than those existing now. Moreover, they appear to display young erosional age, suggesting that are quite young, probably of middle-late Amazonian age.

Abstract

This paper describe the ice-related landforms investigated within Danielson crater, a Martian deep crater which is centered at about 7°W and 8°N, in the region of southwestern Arabia Terra about 775 km south of Becquerel crater. A morphological and morphometric survey of the study area through an integrated analysis of the available Mars images was carried out. The morphological features of the landforms were analyzed through an integrated analysis of Reconnaissance Orbiter (MRO) High Resolution Imaging Science Experiment (HiRISE) and Context Camera (CTX) data. In addition, a DTM of the study area within the Danielson crater was built using two stereo pair HiRISE images. Different landforms interpreted as due to ice-related processes was observed in the study area. The landforms investigated resemble similarly ice-related landforms that can be observed both in the cold region on the Earth, and in other region of Mars. The analysis carried out seem to indicate the presence of landforms attributed to the presence of ground ice and ice-melting processes which can reflect significantly climatic changes and different climatic conditions than those existing now. Moreover, they appear to display young erosional age, suggesting that are quite young, probably of middle-late Amazonian age.
