Trapped 360 feet under water, four men face a deadly situation. Oxygen is running out, and the extreme cold is creeping in. They struggle to breathe as carbon dioxide builds up in the confined space.

There might be a type of exoplanet without dry land. They're called "Hycean" worlds, a portmanteau of "hydrogen" and "ocean." ...

Rising carbon dioxide levels affect more than just the climate; they also affect the chemistry of the oceans. When saltwater absorbs carbon dioxide, it becomes acidic, which alters the aquatic animal ...

A relatively small amount of groundwater trickling through Alaska's tundra is releasing huge quantities of carbon into the ...

A seemingly minor trickle of groundwater beneath Alaska’s tundra is quietly releasing vast amounts of carbon into the ocean.

seagrass can absorb huge quantities of carbon dioxide from the ocean. It stores the carbon and releases oxygen back into the environment. But seagrass also has a superpower. It can absorb huge ...

The world is adept at balancing the warming gases in its atmosphere, but anthropogenic climate change is challenging this ...

Certain metallic rocks seem to be making oxygen in the dark, without light or sunshine, at the bottom of the ocean.

Their pioneering carbon dioxide removal system focuses on effectively exporting CO₂ to the deep ocean. Deployed geo-specific engineered substrates sink rapidly and predictably, ensuring long ...

A relatively small amount of groundwater trickling through Alaska's tundra is releasing huge quantities of carbon into the ocean ... of organic carbon and carbon dioxide released via fresh ...
