The Antarctic Circumpolar Current keeps Antarctica cold.
The Antarctic Circumpolar Current provides a barrier to heat that keeps warm subtropical waters away from Antarctica. Yet, there are a few places where the heat gets through.
Southern bull kelp can drift huge distances before washing ashore.
A chance discovery of some kelp that floated for 20,000km before washing up on an Antarctic beach has opened up a new chapter in our understanding of the currents that swirl around the Southern Ocean.

Sea snakes spend their lives in the water, giving birth to live young at sea, so why are they only found in some of the world's oceans? The answer lies in a combination of climate and geography.
Leaping bottlenose dolphins.
The dolphin population in parts of Western Australia more than halved one year, just as an El Niño event hit over in the Pacific. So what's the connection?

The new sub allows scientists to access some of the most remote and hazardous environments in the ocean.
Ocean gliders are being used to study the Agulhas Current. They bring enormous benefits.
The Agulhas Current is important to South Africa for a variety of reasons. Studying how it impacts the coast has been difficult using traditional methods. But gliders are changing that.
Filipino artists painted an image of MH370 at a high school in the Philippines in 2014 to express solidarity and hope for the passengers and crew of the missing flight.
The search for MH370 has been officially suspended without having found the plane. Where could MH370 be? Was the search in vain?
Steven Morgan deploys ABLE robots in a swimming pool to test how well their programs simulate larval behavior.

Most ocean species start out as larvae drifting with currents. Using underwater robots, scientists have found that larvae use swimming motions to affect their course and reach suitable places to grow.

Researchers have long used such techniques to learn about currents and tides.
A Japanese fish found in Washington after hitching a ride in a boat sent across the Pacific Ocean by the 2011 tsunami.
The 2011 Japan tsunami illustrates how more marine creatures are crossing the oceans than ever before - and not all of them are friendly travellers.
Rain approaching the Pinnacles in Western Australia – how best to understand what past climate change has had on the region?
Scientists are about to embark on a two month mission to find out how Australia and its reefs coped with climate change in the past, and therefore how it should cope with any future change.

Stray debris on a distant beach could well be the first remnant found of missing Flight MH370.
Whale sharks were one of the warm water species to move south during the 2010-2011 marine heatwave.
While eastern Australia trembles in the face of an El Niño, Western Australia's oceans could finally see relief from devastating marine heatwaves.
Warmer waters heading south – here’s sunrise off Manly in New South Wales.
Occasional erratic bursts southward of the East Australian Current (EAC) are thought to have moderated the weather of south-east Australia this autumn and winter and they continue to introduce tropical…

At around 10pm on Sunday 17 August 2014, the container ship AAL Fremantle was being unloaded after arriving in Western Australia’s Fremantle Harbour, when it broke away from its mooring and collided with…
Rubbish strewn on beaches eventually ends up in one of the world’s giant ocean garbage patches.
Most of us have littered at one time or another, and in the process we probably contributed to the enormous of amounts of plastic that enter the ocean every year, eventually ending up in one of the five…
Marlin and Dory plan to hitch a ride to Sydney on the East Australian Current in Finding Nemo.
The animated movie Finding Nemo is responsible for most children’s (and parents’) image of the East Australian Current. Marlin: “I need to get to the East Australian Current – E A C.” Crush: “You’re ridin…

The ongoing search for missing flight MH370 has shown how finding objects such as debris on the ocean is difficult, but finding them underwater in the deep ocean is much more challenging. As of Tuesday…
