10/7/2016 - Large wind ripples on Mars: A record of atmospheric evolution


12:00 PM - 1:00 PM
Geology 3814

Presented By:
Mathieu Lapotre - Caltech


Large wind ripples on Mars are unlike any wind-blown sedimentary structures found in Earth’s sandy deserts. We propose that they form from the effect of wind drag on sand particles, such that preserved ripple stratification may shed light onto the early evolution of the martian atmosphere.
