New method maps how ice shaped landscapes on Mars

The significance of ice in determining what the Mars landscape looks like is a bit of a mystery. A new method is now increasing our understanding of how ice has affected the landscape on the northern plains of Mars.

The northern region of Mars consists of several low-lying plains filled with sediment. Researchers assume that an ancient sea formerly covered these areas.

“Currently these areas are dominated by soil-bound ice, even at latitudes where ice is not in balance with the current climate,” says Geomorphologist Andreas Johnsson.

Along with an international research team, he has developed a new method to find answers to unsolved questions about climate and landscape development on Mars.

“With the new method, we can map very large geographical areas on Mars in less time than before and obtain a better overall picture of the landscape as well. We also found new landforms that have not previously been described or analysed,” says Johnsson.
