Early Mars climate research has well-defined goals (MEPAG 2018). Achieving these goals
requires geologists and climate modelers to coordinate. Coordination is easier if results are …

Extensive evidence of landform-scale martian geomorphic changes has been acquired in
the last decade, and the number and range of examples of surface activity have increased …

Thick deposits cover broad regions of the Martian mid-latitudes with a smooth mantle;
erosion in these regions creates scarps that expose the internal structure of the mantle. We …

Gullies on Mars resemble water-carved channels on Earth, but they are mostly at elevations
where liquid water is not expected under current climate conditions. It has been suggested …

Landforms and deposits observed on the Martian surface suggest that Mars' early climate
supported rivers and lakes over a time span of more than a billion years. But, like Earth …

Aqueous activities on Mars have gradually declined since the Noachian (> 3.7 Ga). Although
water can be stored in the subsurface during the latest epochs, geomorphological evidence …

Although ice in the Martian midlatitudes is typically covered by a layer of dust or regolith, it is
exposed in some locations by fresh impact craters or in erosional scarps. In both cases, the …

Environmental fluid mechanics underlies a wealth of natural, industrial, and, by extension,
societal challenges. In the coming decades, as we strive towards a more sustainable planet …

Geomorphological and mineralogical evidence is consistent with aqueous activity on
ancient Mars, yet explaining the presence of substantial liquid water on early Mars remains …

Wind has been an enduring geologic agent throughout the history of Mars, but it is often
unclear where and why sediment is mobile in the current epoch. We investigated whether …
