National Geographic announced Tuesday that it is officially recognizing the Southern Ocean as the Earth's fifth ocean. The announcement was made to coincide with World Oceans Day. The Southern Ocean ...

The features of the ocean floor help determine how water masses and ocean currents move and how they affect our climate. Biodiversity is also influenced by seafloor landforms. Accordingly, having as ...

A team of scientists led by CU Boulder has identified 30 new areas critical for conserving biodiversity in the Southern Ocean surrounding Antarctica. In a study published Aug. 15 in the journal ...

As Earth’s atmosphere continues to warm, biodiversity in the global ocean is increasingly at risk. Previous studies have shown the Southern Ocean has absorbed the vast majority of excess heat and ...

The biological productivity of the Southern Ocean in the summertime is substantially greater than many previous estimates have suggested, according to new airborne research by the U.S. National ...

New research has found that the Southern Ocean absorbs more carbon dioxide (CO2) than previously thought. Using direct measurements of CO2 exchange, or fluxes, between the air and sea, the scientists ...

Researchers found increased meltwater and rain explain 60% of a decades-long mismatch between predicted and observed temperatures in the ocean around Antarctica. Global climate models predict that the ...

A new study has revealed that small but mighty zooplankton—including copepods, krill, and salps—are key players in the Southern Ocean's ability to absorb and store carbon. Led by an international team ...
