Extensive Freshened Water Beneath Earth’s Ocean Floor Confirmed For The First Time
The goal of this expedition went far beyond collecting sediment cores. Scientists also set out to sample the water stored within the sediments, including from sandy layers that act as […]

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 […]

Organic Carbon In A Submarine Pressure Cooker
The mid-ocean ridge runs through the oceans like a suture. Where the Earth’s plates move apart, new oceanic crust is continuously formed. This is often accompanied by magmatism and hydrothermal […]
