In a seafloor surprise, metal-rich chunks may generate deep-sea oxygen

Instead of sinking from the surface, some deep-sea oxygen may be created by battery-like nodules that split water into hydrogen and oxygen.

Will stashing more CO₂ in the ocean help slow climate change?

Research is needed on how ocean carbon removal methods — such as iron fertilization and direct capture — could impact the environment.

A rapid shift in ocean currents could imperil the world’s largest ice shelf

Roughly the size of Spain, the Ross Ice Shelf stabilizes major glaciers along Antarctica’s coast — and is at risk of retreating, a new study finds.
