Larval black sea bass, an important commercial species along the US Atlantic coast.

Fish can't read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.
Plastic waste on a remote beach in Sri Lanka.
Great areas of rubbish -- known as 'garbage patches' -- are known to form in the Pacific and Atlantic oceans, but not the southern Indian Ocean. Why is that?
Watch out, currents about.
It's good to know how currents are formed in the ocean, as they can be quite dangerous!
Where do the ocean waters that wash the Gold Coast come from?
If you've ever wondered where the ocean currents flow around Australia's coastline then we have a great map for you.
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.

How we showed the Atlantic circulation system is its weakest for 1,600 years.
Yellow-bellied sea snake (

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?
Dooagh beach, Ireland.
A entire beach in Ireland has returned 33 years after being washed away.

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.
University of California, Davis
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…
