How rain sculpts mountains

The shape of Earth's surface can tell us a lot about what kinds of natural events have happened in a region and when. Heavy rainfall, for instance, causes rivers to swell, which can force a river to erode faster into its bed. This connection between... click to read more

Using satellites to look for floating plastics in the ocean

Plastics in the marine environment pose a significant threat to marine life. Macroplastics entering ocean waters have two fates - floating on the surface, or sinking. If not removed by clean-up operations, they may harm or even kill marine life through entanglement or ingestion, and/or... click to read more

What the Earth’s ‘voice’ tells us about its underground architecture

What's under our feet? Our planet has layered internal structures – the central inner and outer cores covered by mantle, crust, and the ground on which you are standing. While these layers are mostly solid, the outer core is liquid since it's extremely hot (around 3000°C)... click to read more

Bringing 100 million-year-old marine microbes back to life

The Earth's entire surface is inhabited by life, but what about what lies beneath, in the subsurface? In the past, we thought of the deep subseafloor as a lifeless zone. We now know it is the "subseafloor biosphere" inhabited by a substantial percentage of Earth's... click to read more

‘Rivers in the sky’ carrying warm air destroy precious Antarctic sea ice

Looking at satellite images or Google Earth, you often find continent-long elongated clouds covering our planet, which may look like "rivers" running through the sky. These rivers are narrow belts of concentrated moisture in the atmosphere. Atmospheric rivers extend from the tropics (where water tends... click to read more
