Mesopelagic fish, long overlooked in ocean chemistry, are now proven to excrete carbonate minerals much like their shallow-water counterparts—despite living in dark, high-pressure depths. Using the ...

As the last Ice Age waned and the Holocene dawned, deep-ocean circulation around Antarctica underwent dramatic shifts that ...

Coral reefs have long been celebrated as biodiversity hotspots—but new research shows they have also played a much deeper ...

The world’s oceans absorb approximately a quarter of all carbon dioxide (CO 2) emissions. During absorption, CO 2 reacts with seawater and oceanic pH levels fall. This is known as ocean acidification ...

New research reveals the importance of winter sea ice in the year-to-year variability of the amount of atmospheric CO 2 absorbed by a region of the Southern Ocean. In years when sea ice lasts longer ...

Ocean alkalinity enhancement (OAE) involves releasing certain minerals into the ocean, sparking a chemical reaction that enables the seawater to trap more CO₂ from the air and mitigating, albeit ...

SINKER is an innovative new instrument equipped with advanced microscopes and cameras to collect detailed data about carbon sinking in marine snow. The ocean is Earth's largest carbon sink, playing a ...

The ocean is one of the planet’s great carbon sinks, absorbing nearly a third of the atmosphere’s greenhouse gas emissions. Swimming in its depths are the great whales, a population whose sheer ...

Marine life plays a pivotal role in Earth's carbon cycle. Phytoplankton at the base of the aquatic food web take up carbon dioxide from the atmosphere, convert it to organic carbon, and move it around ...
