A conveyor belt of ocean water that loops the planet and regulates global temperatures could be heading for a tipping point.

Each year, vast blooms of phytoplankton spread across the Southern Ocean, drawing carbon dioxide from the atmosphere and ...

During the last ice age, the Atlantic Ocean's powerful current system remained active and continued to transport warm, salty ...

Rutgers University marine scientists are using New Jersey-developed tools to measure how iron shortages in Southern Ocean phytoplankton reduce photosynthetic efficiency and slow the conversion of ...

The ocean is continuously ventilated when surface waters sink and transport, for example, oxygen and carbon to greater depths ...

During the last ice age, the Atlantic Ocean’s powerful current system remained active and continued to transport warm, salty water from the tropics to the North Atlantic despite extensive ice cover ...

Global ocean heat content increased by approximately 23 zetajoules (ZJ) in 2025, roughly 40 times annual global primary energy consumption. This is not good.

In 2025, the ocean absorbed an extra 23 zettajoules of heat energy in 2025, breaking the ocean heat content record for the ...

The last ice age did not shut down Atlantic ocean currents, and that discovery may help explain future climate risks.
