Microbes can act as canaries in the coalmine for ocean pollutants such as sewage.
There are more bacteria in the ocean than stars in the known universe. New genetic techniques are letting us use microbes as early warning systems for oceans in trouble from pollution and other stresses.
A new real-time measuring buoy can change the way the maritime industry operates.
Enhanced data collection capabilities will ensure that information collected from the coastline will be seamless.
Too many fish in our seas, like this Pacific bluefin tuna, are being lost to over-fishing – but better management can help.
Over-fishing is a massive environmental and economic challenge. Fortunately, there are new solutions being trialled – including in a tuna hotspot in the Pacific.
Expect to see more ships on the horizon, as global shipping booms. But how well are we measuring and governing what happens at sea?
As the world's land-based economies struggle with around 2% GDP growth, the global marine economy – often talked about as "the blue economy" – is a bright light on the horizon.
Gathering data at the calving front of the Ilulissat Glacier, Greenland.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
Satellite image showing clouds over the Greenland Sea downstream of the ice edge during conditions where there was a large transfer of heat and moisture from the ocean to the atmosphere.
Loss of sea ice near Greenland and Iceland portend a colder future for Europe.
California is the latest state to attempt to ban microplastics from consumer care products. Why these commonly used microbeads are causing major health and environmental problems.
OK, but which sea’s level? And how do you know what it is?
The tides come in, the tides come out. But what is a sea's level? Technology has evolved since we first started gauging the height of the ocean in comparison to the land.
Leiopathes, also known as black corals, are some of the oldest organisms in the sea.
A flock of scientists turned their focus to understand the Deepwater Horizon's impact, including one team that studied deep-sea corals.
Where did the oil go?
Five years after the Deepwater Horizon oil spill, scientists are researching how much oil dropped to sea floor, hitchhiking via 'marine snow.'

Research project combines digital technologies with farms of wave generators to bring plentiful and reliable ocean power closer to commercialization.
Fish can suffocate too.
The oxygen is being sucked out of the ocean, and while much of it is happening far below the surface, it will still affect us above.
The Swedish Byfjord: it may look healthy, but has a deep and stifling secret.
Low oxygen levels in the oceans can dramatically change the community of organisms that live there -- but new techniques to re-introduce oxygen have given a breath of life to a Swedish fjord.
A huge float called an ‘actuator’ is lowered into the water off the Perth coast.

Australia's first large-scale wave energy project is online off the coast of Perth. As Hugh Wolgamot writes, it's a promising development, but technological challenges remain.
Plastic waste washed up on a beach in Haiti.
You might have heard the oceans are full of plastic, but how full exactly? Around 8 million metric tonnes go into the oceans each year, according to the first rigorous global estimate published in Science…
Kelp covered landscape in Western Australia.
Western Australia’s marine environment is unique. Two world heritage areas, the largest fringing coral reef in Australia, and more than a thousand kilometres of underwater forests, supporting incredible…
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…
RV Investigator at sea – It will be formally commissioned in Hobart today.
We know more about the surface of the moon than we do about our deepest oceans, and only 12% of the ocean floor within Australia’s Exclusive Economic Zone has so far been mapped. The reason for this is…
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…
Marine parks need to be big enough to safeguard wide-ranging species, like the sharks being studied here.
Manu San Felix/National Geographic Pristine Seas Expedition
Top scientists, senior government managers, industry representatives, conservationists and even some nations’ presidents are currently in Sydney for the World Parks Congress. This major international meeting…
