Acehnese fishers are among the quarter of the world’s population who live on the coast, and for whom climate-driven changes to the oceans would make life much harder.

Failing to stick to the world’s agreed global warming limit of 2C won’t just affect the atmosphere - it will play havoc with the oceans too, potentially ruining ecosystems on which much of humanity depends.

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?
Wally Gobetz
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.
Whale sharks were one of the warm water species to move south during the 2010-2011 marine heatwave.

Over the past decade, warming air temperatures at Earth’s surface appear to have slowed. But that ignores the vast majority of heat going steadily into the ocean. And, a new paper shows, that makes no difference to the long-term prognosis.
Australia’s network of marine parks - a decade in the making and announced in 2012 - haven’t been implemented yet, and the Abbott government has already placed the plans under review. Why the hurry?
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.
Despite the high concentration of sharks in Cocos, some species have declined in number – a signal on the effectiveness of marine preserves.

Divers at the famed Cocos site off Costa Rica record declines in a number of shark species – a sign that marine preserves are limited protection against illegal fishing.
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.
Ocean acidification from CO2 in the atmosphere will have an economic impact on communities that rely on shellfish.

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…

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…
Turtles are among the species that could be harmed by dredging, even under the government’s new dredge dumping rules.

The Australian government’s latest report on the Great Barrier Reef, submitted to the UNESCO World Heritage Centre last Friday, has been carefully crafted and word-smithed, with many of its claims supported…
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 to data collected by thousands of floating robots published today in Nature Climate…
It has long been news that overfishing persists in many of the world’s oceans. Fish and invertebrate stocks have been over-exploited for our ever-hungry, growing human population, leaving some species…
