Could this new technology do for the microscopic marine world what the first telescopes did for the heavens above?

Closing the passage between the Atlantic and Pacific oceans strengthened the gulf stream and helped kick off ice ages.
Climate change isn't the only thing making sea levels higher and cyclones more intense.

Researchers have long used such techniques to learn about currents and tides.
The oceans are teeming with life and potential – but the high seas are still largely ungoverned.
The open oceans are the world's "wild west", falling outside any nation's jurisdiction. UN negotiations are aiming to draft new laws for the high seas.
The new boat will join RRS Ernest Shackleton (pictured) in the UK’s fleet.
A new polar research vessel might be saddled with a daft name, but its work is all important.

Things can change disturbingly quickly – just ask the people who once farmed the Sahara.
Early signs of bleaching coral in Kaheohe Bay Hawaii, August 2015.

Many corals can't make it through the bleaching events caused by warming ocean waters. But some can – and scientists are trying to learn more about the sources of their resilience.

Stray debris on a distant beach could well be the first remnant found of missing Flight MH370.
The Argo ocean profiling floats are part of a year-round monitoring network for the world’s oceans.
In 1985, when CSIRO's marine labs were launched, a seven-day weather forecast was little better than chance. Now, thanks to advances in our understanding of the oceans, our predictions are far better.
The World Heritage Committee has called for a comprehensive assessment not just of the threats to the Great Barrier Reef, but of their cumulative effect.

The government says it has met all of the recommendations for safeguarding the Great Barrier Reef. But a close reading of the dozens of UN recommendations shows that many have been only partly fulfilled.

A new report aims to establish exactly what we do and don't know about the effects of dredging on the Great Barrier Reef, and suggests that managing fine sediments will be one of the biggest challenges.
It’s not always as ostentatious as Dubai, but our coastlines are home to ever-growing numbers of manmade structures.
Urban sprawl has spread to the sea, as more and more man-made structures are being built along the world's coastlines. Just as we do on land, we need to think about how to build sustainably at sea.
A new research expedition is documenting the deep-sea denizens of the Perth Canyon, such as this flytrap anemone and basket star.
UWA/Schmidt Ocean Institute
The Perth Canyon, off Australia's west coast, is twice the size of the Grand Canyon. But only now, with the help of remote-controlled submarines, are researchers finding out what lives in its depths.
Researchers deploy robotic Argo floats into the ocean to measure temperature.
The oceans are continuing to warm steadily despite an apparent slowdown in global warming at the earth’s surface, according…
Bad news for icebergs: oceans in the Southern Hemisphere have been soaking up more heat energy than previously thought.
The upper layers of the world’s oceans have been warming much faster than oceanographers realised over the past few decades…
The AAL Fremantle, borne along by a meteotsunami, hits the rail bridge next to Fremantle Harbour.

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…
We need to play our cards right if Australia’s marine environments are to keep us afloat.
In many ways, Australia is defined by the oceans surrounding us. We have the world's third largest ocean territory, most of our trade travels by sea, and we have vast offshore resources.
The oceans are filled with garbage. Who’s in charge of the cleanup?
I was in the middle of giving a talk on the marine debris problem at a notable Californian marine research institute, when I drank the last of my water bottle, threw it onto the hall floor from the podium…
Debris or not debris? Floating rubbish could hamper the search for MH370.

Frustratingly, the search for missing Malaysia Airlines flight MH370 has turned up many floating objects, but none of them are from the plane. That’s largely because the latest search area is likely to…
