Sedimentary layers record the history of the Earth. They contain stratigraphic cycles and patterns that precisely reveal the succession of climatic and tectonic conditions that have occurred over millennia, thereby enhancing our ability to understand and predict the evolution of our planet.

Vital Signs: Seismology of Ocean Worlds

Ice covered ocean worlds are probably seismically active. Measuring that activity can provide information about global and local habitability.

Rotation in planetary atmospheres plays an important role in regulating atmospheric and oceanic heat flow, cloud formation and precipitation.

At the bottom of the sea, volcanic and magmatic forces create hot springs that spew super-heated water into the deep ocean.

The prospect of finding ocean-bearing exoplanets has been boosted, thanks to a pioneering new study. An international team of scientists, including from the University of Exeter, has discovered an immense cloud of hydrogen escaping from a Neptune-sized exoplanet.

"Who in his wildest dreams could have imagined that, beneath the crust of our Earth, there could exist a real ocean...a sea that has given shelter to species unknown?"

In this paper we present a series of models for the deep water cycle on super-Earths experiencing plate tectonics.

NASA's Cassini spacecraft and Deep Space Network have uncovered evidence Saturn's moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes.

Lobster-Shaped Extrasolar Oceans

Alien planets circling the most common stars in the universe may often have strange lobster-shaped oceans on their surfaces, researchers in China now say.

New Evidence for a Martian Ocean

Scientists studying data from NASA's Mars Reconnaissance Orbiter have discovered new evidence that Mars may have once had a vast ocean on its surface. The research team spotted an ancient delta where a river might have emptied into an ocean so large that it covered much of the planet's northern hemisphere.
