Earth’s deep interior may hold water equal to today’s oceans, challenging long-held views of how the planet became habitable.

The Indian Ocean holds the lowest gravity anomaly on Earth, a vast and subtle depression in the planet’s gravitational field located south of Sri Lanka. Known as the Indian Ocean geoid low, it causes ...

Scientists have shown that temperature differences deep within Earth's mantle control the elevation and volcanic activity along mid-ocean ridges, the colossal mountain ranges that line the ocean floor ...

Southwest Research Institute’s Dr. Simone Marchi collaborated on a new study finding the first geophysically plausible scenario to explain the abundance of certain precious metals — including gold and ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle. Some of that water carries a ...

The evolution of our Earth is the story of its cooling: 4.5 billion years ago, extreme temperatures prevailed on the surface of the young Earth, and it was covered by a deep ocean of magma. Over ...

The oceanic lithosphere forms at the summit of ocean ridges during seafloor spreading. Still, the formation of ocean basins is complex, influenced by smaller-scale convection, stagnated pieces of the ...

An international research group led by Dr. Takayuki Ishii from HPSTAR and Okayama University, Institute for Planetary Materials, in collaboration with colleagues from Bayerisches Geoinstitut, ...
