How Microbes Use Earth’s Ancient Carbon

Hydrothermal vents on the ocean floor release carbon dioxide that is many million years old. This old carbon originates from the Earth’s interior, and it escapes either directly from the […]

Jupiter’s Moon Europa Has A Seafloor That May Be Quiet And Lifeless

The giant planet Jupiter has nearly 100 known moons, yet none have captured the interest and imagination of astronomers and space scientists quite like Europa, an ice-shrouded world that is […]

Marine Mineral Formations in the Arctic Ocean Challenge Existing Geologic Theories

A new study from USGS describes a previously unknown process of marine mineral formation in the Arctic Ocean, driven by frictional heating along tectonic faults rather than by hydrothermal activity.
