Ocean eddies are huge loops of swirling current, sometimes hundreds of kilometers across and reaching down over 1,000 meters. They're so large you can see them on satellite images.

When eddy currents spin one way, they can send heat to the depths. When they spin another, they can bring cold water towards the surface. olrat/Shutterstock What does this mean for ocean life?

Ida passed over an ocean eddy, a shallow swirl of warm water that spun off the Loop Current, as it rapidly intensified into a Cat 4 hurricane before making landfall in Louisiana in 2021.

Firstly, the mean predictability limit of cyclonic eddy (CE) tracks is approximately 44 days, while anticyclonic eddy (AE) tracks have a predictability limit of around 39 days in the South China Sea.

Our new research demonstrates the link between a warm ocean eddy and a record-breaking marine heatwave which struck off Sydney from December 2021 to February 2022. Now it's happening again.

Ocean eddy currents are driving extreme heat and cold events in the deeper sea, home to the world’s most abundant animal and its largest migration.

Our new research demonstrates the link between a warm ocean eddy and a record-breaking marine heatwave which struck off Sydney from December 2021 to February 2022. Now it’s happening again.

On land, we're familiar with heatwaves and cold snaps. But the deep sea also experiences prolonged periods of hot and cold. Marine heatw ...
