Hypotheses accounting for the formation of concentric crater fill (CCF) on Mars range from ice-free processes (e.g., aeolian fill), to ice-assisted talus creep, to debris-covered glaciers. Based on analysis of new CTX and HiRISE data, we find that concentric crater fill (CCF) is a significant component of Amazonianaged glacial landsystems on Mars. We present mapping results documenting the natu...

This article shows acoustic measurements from Svalbard archipelago in the Arctic, located Arctic Ocean. The aim of research was to show soundscape as well record and analyse spatial-temporal dynamics environment, human impact on collect baseline data for future comparative research. is interesting many science disciplines because it has an arctic climate and, at same time, relatively easily acc...

Introduction: The geomorphology and geology of Mars, for at least the last 20 years [1], has presented a consistent, coherent picture of that planet as water-rich, such that aqueous activity has occurred, sporadically at least, on its surface throughout its history. The robustness of this conclusion is evidenced in its persistence , despite difficulties of reconciliation with geo-physical and g...
