Exclusive: leading marine scientist says Moreton Bay, one of three sites shortlisted, is bad choice due to risk to reactors if jellyfish sucked in

Australia’s nuclear-powered submarines would “inevitably” be forced into an emergency reactor shutdown by swarms of jellyfish if the fleet was based in Brisbane, a leading marine scientist says.

The Australian government this week released a shortlist of three sites – Brisbane, Newcastle and Wollongong – as a potential east-coast home port for the nuclear submarine fleet, which will arrive in about 2036 under the Aukus partnership with the US and the UK.

Stranding of three whales in Corfu raises alarm over seismic testing for fossil fuels

Posted on by

While cause remains unconfirmed, green groups fear the three whales could be the ‘tip of iceberg’ with many more animals hurt

Environmental groups have linked the beaching of three whales in Corfu to seismic testing for oil and gas in the waters off the Greek island.

Two Cuvier’s beaked whales were found stranded at Arillas and Agios Gordios beaches on the west of the island on 20 February. A third beaked whale ran ashore on Agios Gordios beach the day after.

Loss of coastal seagrass meadows due to sediment-laden flood water likely to cause mass starvation in aquatic wildlife

Hundreds of dugongs and thousands of turtles will likely starve to death in coming months after flood waters smothered Queensland’s seagrass meadows with sediment.

Col Limpus, the chief scientist for wildlife and threatened species in Queensland’s environmental department, is so familiar with the pattern of death that follows big floods he can provide a timeline of what is in store.

The squit and the whale: can artificial faeces revive the ocean ecosystem?

Posted on by

A scientific experiment hopes to restore vital nutrients to the ocean by using fake excrement that would once have been produced by the endangered mammal

In a few weeks an international group of scientists will launch an unusual marine research project. They will dust the surface of the Indian Ocean with artificial whale faeces.

The aim of this excremental experiment is straightforward. It is to determine if it is possible to reboot marine ecosystems that have been starved of nutrients and in the process restore dwindling fish populations. It is also hoped the project will help in the battle against the climate crisis.

Description of ingredient as ‘ocean fish’ means owners are unwittingly giving their pets vulnerable species for dinner

Pet food containing endangered sharks is being fed to cats and dogs by unwitting owners, a study has revealed.

Scientists found that several brands contained endangered species but listed only vague ingredients such as “ocean fish”, meaning that consumers are often oblivious.

Despite nearly a third of shark species nearing extinction, Spain supplied 51,000 tonnes of shark fins from 2003-20, says IFAW

European countries are selling so many shark fins to Asia that they dominate nearly half the trade, a study has found.

Shark populations continue to decline, driven by the global shark fin trade. Last year, scientists found a third of sharks and ray species have been overfished to near-extinction, jeopardising the health of entire ocean ecosystems and food security for many countries.

‘Showing respect’: revival of Japanese technique that promises fish a better way to die

Posted on by

Fishermen in Mexico are using the ike jime method, which aims to reduce fish trauma, to improve the quality of catches and help sustainability

Every morning, hundreds of small white fishing boats dot the dark blue waters of Veracruz’s coastline on the Gulf of Mexico. Most of the crews, many of whose families have been fishing for generations, employ traditional methods – using nets to catch large numbers of fish, which then slowly asphyxiate once out of the water.

But a few of the fishermen are doing something different, using a technique that emerged in Japan several centuries ago. It is a method for slaughtering fish that emulates a process called ike jime, which is based on a simple scientific principle: the less trauma the fish experiences, the longer the flesh remains fresh.

World leaders to gather in Nairobi next week to discuss first global treaty to combat plastic waste

World leaders will come together online and in Nairobi, Kenya, next week, in what is described as a “critical moment” in progress towards the first ever global treaty to combat plastic waste. Inger Andersen, director of the UN Environment Programme, said an agreement at the UN environment assembly could be the most important multilateral pact since the Paris climate accord in 2015.

Public disgust and impatience over the growing mountain of plastic waste has led to an unprecedented “degree of focus” that could see member states agreeing a blueprint for a legally binding treaty to control plastics “from source to sea”, she said.

As One Ocean event in Brest aims to deliver action in areas from pollution to overfishing, activists warn against ‘bluewashing’

Up to 40 world leaders are due to make “ambitious and concrete commitments” towards combating illegal fishing, decarbonising shipping and reducing plastic pollution at what is billed as the first high-level summit dedicated to the ocean.

One Ocean summit, which opens on Wednesday in the French port of Brest, aims to mobilise “unprecedented international political engagement” for a wide range of pressing maritime issues, said its chief organiser, Olivier Poivre d’Arvor.

Australians ingest a credit card’s worth of plastic a week – so what’s it doing to us?

Citizen science project mapping microplastics menace in hope of halting spread

Head down to Sydney’s Manly Cove on a weekend, and you might see groups of people crouching diligently on the sand. They’re not searching for shells or bloodworms, but something just as visually striking, not least because it shouldn’t be there: coloured pieces of hard plastic, fragments of polystyrene foam and fibres from fishing line.

For the last three years, a group of volunteers has been surveying the beach each month for microplastics, as part of the Australian Microplastics Assessment Project.

Colloquially known as Ausmap, the citizen science project has collected more than 3.5m pieces of microplastic from more than 300 beaches around the country, ranging from Thursday Island in the north to Bruny Island, off Tasmania’s south-east coast.

How ‘super-enzymes’ that eat plastics could curb our waste problem

Posted on by

Nudged along by scientists and evolution, micro-organisms that digest plastics have the potential to create an efficient method of recycling

Beaches littered with plastic bottles and wrappers. Marine turtles, their stomachs filled with fragments of plastic. Plastic fishing nets dumped at sea where they can throttle unsuspecting animals. And far out in the Pacific Ocean, an expanse of water more than twice the size of France littered with plastic waste weighing at least 79,000 tonnes.

The plastic pollution problem is distressingly familiar, but many organisations are working to reduce it. Alongside familiar solutions such as recycling, a surprising ally has emerged: micro-organisms. A handful of microbes have evolved the ability to “eat” certain plastics, breaking them down into their component molecules. These tiny organisms could soon play a key role in reducing plastic waste and building a greener economy.

Environmentalists spot floating carpet of blue whiting covering thousands of square metres after spill from the FV Margiris

Dutch-owned trawler FV Margiris, the world’s second-biggest fishing vessel, has shed more than 100,000 dead fish into the Atlantic Ocean off France.

France’s maritime minister, Annick Girardin, called the images of the dead fish – which formed a floating carpet of carcasses spotted by environmental campaigners – “shocking” and has asked the national fishing surveillance authority to launch an investigation.

Japan’s return to commercial whaling in 2019 has left few buyers for Iceland’s meat

Iceland, one of the only countries that still hunts whales commercially, along with Norway and Japan, plans to end whaling from 2024 as demand dwindles, the fisheries minister has said.

“There are few justifications to authorise the whale hunt beyond 2024,” when current quotas expire, Svandis Svavarsdóttir, a member of the Left Green party, wrote in Morgunblaðið newspaper.

Formerly rare high temperatures now covering half of seas and devastating wildlife, study shows

Extreme heat in the world’s oceans passed the “point of no return” in 2014 and has become the new normal, according to research.

Scientists analysed sea surface temperatures over the last 150 years, which have risen because of global heating. They found that extreme temperatures occurring just 2% of the time a century ago have occurred at least 50% of the time across the global ocean since 2014.

‘Families are starving’: Chinese trawlers’ overfishing is destroying lives, say Sierra Leoneans

As illegal industrial-scale fishing by foreign fleets pillages fish populations, despairing coastal communities feel powerless

Along Tombo’s crumbling waterfront, dozens of hand-painted wooden boats are arriving in the blistering midday sun with the day’s catch for the scrum of the market in one of Sierra Leone’s largest fishing ports.

In a scrap of shade at the bustling dock, Joseph Fofana, a 36-year-old fisherman, is repairing a torn net. Fofana says he earns about 50,000 leone (£3.30) for a brutal, 14-hour day at sea, crammed in with 20 men, all paying the owner for use of his vessel. “This is the only job we can do,” he says. “It’s not my choice. God carried me here. But we are suffering.”

Research is first to document coordinated female-led pods ramming world’s largest animal and eating its tongue before it dies

From snatching sea lions off beaches to stunning fish with a strike of their tails, orcas are renowned for their highly specialised hunting techniques passed down over generations. Now, for the first time, killer whales have been recorded hunting the planet’s largest animal – the blue whale – in coordinated and brutal attacks.

Female-led pods of killer whales, also known as orcas, have been recorded killing and eating blue whales in three separate attacks off the coast of Australia since 2019, according to a paper published in Marine Mammal Science.

Coral crusaders: Costa Rica’s young divers learn to protect their seas

In Puerto Viejo, scuba diving was once just for tourists, but a centre is training young people with few opportunities to care for the ocean on their doorstep

“I put fresh almond leaves in your underwater masks as anti-fogging – a way to avoid using chemicals. You can remove them once in the water, just before diving,” says Salim Vasquez, 14, pushing her dreadlocks away from her mask.

She distributes the equipment to her fellow divers, who are aged between 14 and 24, and Ana María Arenas, a group coordinator. It is 8am on a cloudy Sunday morning in Puerto Viejo, a Jamaican-inspired city in the south of Costa Rica. The young conservationists are preparing to dive into the Caribbean water for their weekly reef monitoring.
