Leave the ocean garbage alone: we need to stop polluting first

Recent plans to clean plastics from the five massive ocean garbage patches could do more damage to the environment than leaving the plastic right where it is. There is no doubt that the focus on cleaning…

Final frontiers: the deep sea

With the global population now well over seven billion people there are few remaining parts of the world relatively untouched by human activity. We assess the current state and future prospects of five…

Deep-sea microbes thrive under pressure

Microbes have been found thriving in even the deepest spot on the ocean floor. Research found the Mariana trench, nearly…
Plastic is a major threat to our seabirds and marine life - this bird has filled its stomach with plastic during the 80-90 days it lived. Ian Hutton

Plastic and politics: how bureaucracy is failing our forgotten wildlife

Seabirds: the poster children for ocean health. Fishers use them to identify fishing hot spots. Environmental and marine scientists use them as indicators of the condition of the ocean environment due…
Recent research shows an acidifying ocean is more damaging to coral than we’d hoped. Community Eye Health

Jumps in ocean acidity put coral in more peril

Ocean acidification - where the ocean becomes less alkaline as it absorbs excess CO2 from the atmosphere - has been described as the evil twin of global warming. Yet, remarkably, it is only over the past…

Abnormal hydro-heatwave explained

A number of factors contributed to the marine heatwave that affected ecology off the WA coast in 2011. A team of oceanographers…

Many marine species remain unknown

There are 226,000 described marine species in the world but research suggests more than 450,000 remain unknown. Using knowledge…
Fisheries around the world are depleted, but they can be saved. Isaac Pearlman

It is still possible to make fisheries sustainable

Many fisheries around the world are in bad shape and getting worse. Solving this problem will require innovative monitoring and management tools, but we can provide tremendous benefits if we act now to…
Understanding the stingray’s significance can help us understand opposition to James Price Point gas plans. Joy VanBuhler

Beware the stingray: Indigenous heritage and WA’s gas plans

For overwhelming economic, social, cultural and environmental reasons the LNG precinct proposed for Walmadany (James Price Point) should not be built…In sum, such a project is against the national interest…

The decay of the Great Barrier Reef calls for a reckoning

There is a myth about Australia’s Great Barrier Reef, that goes like this: because it is so big, biodiverse, so well-managed and generally bloody awesome, the GBR is immune to climate change and other…
Could waves and ocean currents hold a key to a renewable energy future? Sunova Surfboards

Ocean power making waves in Australia’s clean energy future

CSIRO recently announced that energy from the ocean could supply 11% of Australia’s demand by 2050. That is enough to power a city the size of Melbourne. It is a bold claim, but it’s time for Australia…
We thought we’d set a safe limit on climate change - 450ppm CO2 - but it may be too high for most of the world’s reefs. Paul Toogood

Climate change guardrail too hot for coral reefs?

One of the ambitions of the United Nations Framework Convention on Climate Change (UNFCCC) is galvanising the international community to avoid dangerous interference with Earth’s climate. To do this, it…
Microbial abundances in the sub-seafloor environment are much more variable than thought. giveawayboy

Drastic measures: a revised estimate of Earth’s microbes

A paper released today in the journal PNAS provides a new estimate of microbial abundance, in light of new information, from the sub-seafloor realm (the so-called “deep biosphere”). As such, we now have…
There is no evidence that hunting and killing sharks reduces attacks on humans. US Fish and Wildlife Service

Who’s hunting who? Misguided responses to shark attacks

The most recent fatal encounter between a shark and a surfer off the coast of Western Australia is a tragic loss of human life. It prompted a Western Australian government reaction to “hunt and kill” the…
