Recent thaw on Mars: evidence from Earth analogues and high-resolution elevation data

The surface of Mars was long thought to be dry and inactive, but recent data including high-resolution images and topography have changed the way we think about Mars’ surface processes. Now Mars is considered to be similar to the dry, cold desert climate of the Antarctic, with extensive permafrost and associated landforms. I will talk about my work concerning ground-ice on Mars, with particular focus on the landforms that provide evidence of thaw, or even freeze-thaw cycles. I will then briefly summarise the implications for Mars's climate and recent geological history.

Tea and coffee will be served following the seminar.
