If the ocean circulation, known as AMOC, shuts down, it would be a climate disaster, particularly for Europe and North America. New research shows why that might not happen as soon as some fear.

Baby corals may hold promise for building coral reef resilience in Seychelles and beyond.
New research shows climate change can drive sudden ocean cooling too. This can have devastating effects on marine life such as bull sharks and manta rays.
This marine ecosystem is so important it’s one of the main reasons the federal government has greatly reduced the area available for offshore wind farms in the region.
Giant eddy currents in the sea spread heat. But if trapped in place, they can cause marine heatwaves deadly to sea life. And there’s a big one shaping up off Sydney right now.
Oceanographic systems vary over years, decades and centuries.
A sea voyage and a satellite mission will combine to produce a more detailed picture of the ocean’s currents than ever before.
Expect more extremes and a range of ‘surprises’ to exacerbate the climate emergency.
Rip currents are a leading cause of near-shore drownings, but there are effective ways to survive one. And these phenomena also play important ecological roles that are an emerging research area.
Scientists have detected a 30% slowdown of the deep ocean currents that form in Antarctica, with profound consequences for Earth’s climate, sea level and marine life.
Working with underwater robots, scientists show how deep sea mountains and fast currents between Antarctica and South America play a crucial role in stabilizing the climate.
In a plot reminiscent of the 2004 movie The Day After Tomorrow?, Australian scientists are warning that the Southern Ocean’s deep “overturning” circulation is slowing and headed for collapse.
Remote islands in the Indian Ocean are now strewn with plastic waste – the origin of this waste has until now not been established.
Our oceans have absorbed almost all the extra heat we’ve trapped with our emissions. Now we know how this heat moves in ocean currents.
The direction a beach faces, relative to wind direction, largely determines how many bluebottles are pushed to shore.
Studying these deposits gives scientists information about how past environments change. That, in turn, gives us informed estimates on how climates and environments will change in the near future.
Ida exploded from a weak hurricane to a powerful Category 4 storm in less than 24 hours, thanks to heat from an ocean eddy. An oceanographer explains its rapid intensification.
New research suggests that an effective way to locate and track large concentrations of microplastics in the ocean could be from high in the sky.
Thousands of shipping containers are lost at sea each year, dispersing Lego, inkjet cartridges and rubber ducks across the world’s beaches.
Our team discovered clear changes in the distribution and strength of ocean eddies. These changes have never been detected before.
