What to know about Scientific Research

The article reports on new research published in Communications Earth & Environment regarding vertical ocean currents in the Southern Ocean. Using satellite data and underwater gliders, scientists found that these currents are deeper and faster than previously understood, which may improve climate predictions regarding heat and carbon absorption.

What happened

June 9, 2026 report Satellite data reveal Southern Ocean vertical currents diving 3,000 feet below surface Paul Arnold Author Lisa Lock Scientific Editor Robert Egan Associate Editor Ocean currents are not just horizontal motions that flow from side to side.

Why it matters

There are also vertical currents that act like deep-sea elevators, pushing heat and carbon down into the deep, while bringing up vital nutrients and dissolved gases to the surface.

Common ground

Our knowledge of these vertical movements has been limited by a lack of detailed data, but new research published in the journal Communications Earth & Environment is providing new insights into how these hidden currents operate in the Southern Ocean.
