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.
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.
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.
The grisly discovery of a disembodied foot on a NSW beach was a tragic twist in the mystery of missing woman Melissa Caddick. Such tragedies can also reveal hidden currents connecting the planet.
