Nearly 4,000 m beneath the Pacific, in water so dark that sunlight has never penetrated, scientists have stumbled on a new ...

Marine researchers exploring extreme depths say they have discovered an astonishing deep-sea ecosystem of chemosynthetic life that’s fueled by gases escaping from fractures in the ocean bed. The ...

You are taught early in science that oxygen on Earth comes from sunlight. Plants, algae, and cyanobacteria use light to split ...

An underwater voyage has revealed a network of creatures thriving at the bottom of deep-sea ocean trenches. In these extreme environments, the crushing pressure, scant food and lack of sunlight can ...

A groundbreaking study in the journal Science, has unveiled how deep ocean currents—known as global overturning circulation—play a pivotal role in shaping the diversity and function of microbial life ...

In a step toward better understanding how the ocean sequesters carbon, new findings from UC Santa Barbara researchers and collaborators challenge the current view of how carbon dioxide is "fixed" in ...

Researchers have uncovered surprising evidence that the deep ocean’s carbon-fixing engine works very differently than long assumed. While ammonia-oxidizing archaea were thought to dominate carbon ...

An underwater voyage has revealed a network of creatures thriving at the bottom of deep-sea ocean trenches, researchers said in a newly published paper. The deep-sea trenches, also called Hadal ...
