Unprecedented ice loss in Russian ice cap

In the last few years, the Vavilov Ice Cap in the Russian High Arctic has dramatically accelerated, sliding as much as 82 feet a day in 2015, according to a new multi-national, multi-institute study led by CIRES Fellow Mike ...

Did plate tectonics set the stage for life on Earth?

A new study suggests that rapid cooling within the Earth's mantle through plate tectonics played a major role in the development of the first life forms, which in turn led to the oxygenation of the Earth's atmosphere. The ...

Flow in the asthenosphere drags tectonic plates along

New simulations of Earth's asthenosphere find that convective cycling and pressure-driven flow can sometimes cause the planet's most fluid layer of mantle to move even faster than the tectonic plates that ride atop it.

Landscape evolution intrinsic to ancient mountain settings

Over the last century, scientists have struggled with a lingering question in geology: Why do the structure and elevation of some mountains continue to evolve long after the tectonic forces that formed them cease?

New estimates of Mercury's thin, dense crust

Mercury is small, fast and close to the sun, making the rocky world challenging to visit. Only one probe has ever orbited the planet and collected enough data to tell scientists about the chemistry and landscape of Mercury's ...
