Your coastal town’s climate score? There’s a website for that

Australia’s coastal towns, many built around fisheries and tourism, are particularly vulnerable to climate change. South east and south west Australia are marine hotspots — they are warming much faster…

15 years from now, our impact on regional sea level will be clear

Human activity is driving sea levels higher. Australia’s seas are likely to rise by around 70 centimetres by 2100 if nothing is done to combat climate change. But 2100 can seem a long way off. At the moment…
Shark Bay is one of Australia’s 19 World Heritage Areas, home to dolphins, dugongs, and sharks. Matthew Fraser

Climate change threatens Western Australia’s iconic Shark Bay

In the summer of 2010-2011 Western Australia experienced an unprecedented heatwave — but not on land. Between December 2010 and April 2011, sea temperatures off the WA coast reached 3C above average, and…
Bad news for icebergs: oceans in the Southern Hemisphere have been soaking up more heat energy than previously thought. Andrew Meijers/BAS

Southern oceans heating up faster than scientists realised

The upper layers of the world’s oceans have been warming much faster than oceanographers realised over the past few decades…

Track boats with GPS to stop illegal fishers draining the seas

The ocean, seen from a beach or from a plane, seems vast, ancient and invulnerable. It’s hard to imagine that 90% of life on earth lives below the waves, across 1.3 billion cubic kilometres of water and…

Drought in store as El Niño’s western cousin to grow stronger

Over the past few months, a lot of attention has been paid to the potentially strong El Niño event brewing in the Pacific Ocean. But there is also the potential for an emerging climate phenomenon in the…

We need a global conservation agreement for the high seas

The high seas cover about 50% of Earth’s surface and host a major share of the world’s biodiversity, but remain largely ungoverned. With increasing threats to open ocean ecosystems, now more than ever…
The ocean is all stirred up with what we’re doing to it. NASA

The ocean is not just huge, but also hugely important

Carl Sagan’s description of our planet as a “pale blue dot” captured two important elements about the Earth: its loneliness in the enormity of space, and the ocean’s overwhelming dominance of the planet…

IPCC preview: deep trouble brewing in our oceans

Scientists are meeting this week in Yokohama, Japan, to finalise and approve the latest report from the Intergovernmental Panel on Climate Change’s Working Group II – the part of the IPCC process that…

Marine conservation efforts are failing to take five key steps

Some of the world’s most vulnerable marine habitats are being failed by the conservation orders put in place to protect them. As the Environmental Audit Committee meets to discuss how it will implement…
Much of Australia’s waste plastic is ending up in the ocean, and in fish. John Schneider

Australian waters polluted by harmful tiny plastics

Each square kilometre of Australian sea surface water is contaminated by around 4,000 pieces of tiny plastics, according to our study published today in journal PLOS ONE and data repository Figshare. These…

The ocean is not broken, but consumer behaviour is

In an emotional article making waves on social media at the moment, yachtsman Ivan Macfadyen reports seeing no marine life at sea, only floating rubbish, while sailing across the Pacific. He concludes…
It’s loud out there! We’re just beginning to understand how our noise affects whales' ears. Sam Scholes

Too much noise in the ocean for whales' sensitive ears

We might only notice whales when they appear in our world, but beyond the scopes of whale watchers, whales and dolphins live rich - and noisy - lives. In fact scientists are only just beginning to understand…
