Deep-sea mining causes huge decreases in sealife across wide region, says study

Posted on by

Scientists caution against rush to mine the seabed, and say it could be decades before the full impact on marine life is known

Animal populations appear to decrease where the deep sea is being mined, and the impact on marine life of the controversial industry may involve a wider “footprint” than previously expected.

According to analysis of seabed ecology undertaken after drilling tests in 2020 in Japan – the country’s first successful extraction of cobalt crusts from deep-sea mountains – there was a decrease in marine life such as fish and shrimp at the site a year later. The density had dropped even further in areas outside the impact zone, by more than half.

Ireland and Sweden join countries calling for moratorium on extraction of metals from seabed as UN-backed authority prepares for crucial talks

The list of countries calling for a pause on deep-sea mining continued to grow this week ahead of a key moment that mining companies hope will launch the fledgling industry, and its opponents hope could clip its wings, perhaps for good.

Ireland and Sweden became the latest developed economies to join critics, including scientists, environmental organisations and multinationals such as BMW, Volvo and Samsung. The carmakers have committed not to use minerals mined from the seabed in their electric vehicles.

Rising temperatures in north Atlantic and drop in Antarctic sea ice prompt fears of widespread damage from extreme weather

“Very unusual”, “worrying”, “terrifying”, and “bonkers”; the reactions of veteran scientists to the sharp increase in north Atlantic surface temperatures over the past three months raises the question of whether the world’s climate has entered a more erratic and dangerous phase with the onset of an El Niño event on top of human-made global heating.

Since April, the warming appears to have entered a new trajectory. Meanwhile the area of global sea ice has dropped by more than 1 million sq km below the previous low.

‘We could lose our status as a state’: what happens to a people when their land disappears

Small island countries press for guarantees as rising sea levels risk leaving their citizens stateless

Small island nations would rather fight than flee, but rising sea levels have prompted apocalyptic legal discussions about whether a state is still a state if its land disappears below the waves.

The Pacific Islands Forum, which represents many of the most vulnerable countries, has invited international legal experts to consider this question and begun a diplomatic campaign to ensure that political statehood continues even after a nation’s physical fabric is submerged.

Titanic sub: ‘We have to remain hopeful’, says US Coast Guard, as vessel thought to have less than 20 hours of oxygen left – live

Rescue team says every noise being tracked and analysed; ‘every possible effort’ being made to bring missing crew home, says Polar Prince co-owner

An oceanographer has told the BBC the underwater noises give hope that those on board are still alive.

“There are plenty of sound sources in the ocean, but it does give hope,” Simon Boxall, a senior lecturer in oceanography at the University of Southampton, told the World Service.

A Canadian military surveillance aircraft detected underwater noises as a massive search continued on Wednesday in a remote part of the North Atlantic for a submersible that vanished while taking five people down to the wreck of the Titanic.

A statement from the US Coast Guard did not elaborate on what rescuers believed the noises could be, though it offered a glimmer of hope for those lost abroad the Titan as estimates suggest as little as a day’s worth of oxygen could be left if the vessel is still functioning.

Business groups argue ‘same job, same pay’ laws would disadvantage workers

I mentioned a little earlier that business groups have glommed together to launch a campaign against the federal government’s proposed “same job, same pay” industrial relations laws.

The so-called ‘Same Job, Same Pay’ proposals does not mean equal pay for men and women. It does not speak of fairness and justice, as its name falsely represents.

It means by law, employers will have to pay workers with little knowledge or experience exactly the same as workers with decades of knowledge and experience.

Without a real threat of losing passengers to other airlines, the Qantas and Virgin Australia airline groups have had less incentive to offer attractive airfares, develop more direct routes, operate more reliable services, and invest in systems to provide high levels of customer service.

Fears biodiversity proposals could be abandoned amid opposition from lobby groups and some countries

MEPs have been accused of whipping up “a culture war against nature” after the fisheries and agriculture committees voted against the EU’s biodiversity restoration law.

Last June, the European Commission revealed proposals for legally binding targets for member states to restore wildlife on land, in rivers and the sea. The nature restoration law was announced alongside separate legislation proposing a crackdown on chemical pesticides with the aim of reversing the catastrophic loss of wildlife on the continent.

Up to 50,000 whales expected to pass Australia’s east coast during annual migration from Antartica to Great Barrier Reef

Carrie Davis describes seeing her first adult humpback whale of the season launching out of the water off the coast of Sydney last week as magical.

“It’s just this feeling of awe to see this fat whale of that size get all that body out of the water,” said Davis of Go Whale Watching in Sydney. “No matter how many times you see it, it always takes your breath away.”

Scientists discover why sea urchins are dying off from US to the Caribbean

Posted on by

A research team has discovered a parasite that’s been killing off sea urchins, but there’s no method to eliminate it yet

Marine biologists at a Florida university say they have solved the mystery of a mass die-off of long-spined sea urchins from the US to the Caribbean.

The scientists blame a microscopic, single-cell parasite for the die-off, which took hold early last year. Affected Diadema antillarum urchins lose their spines and suction, then succumb to disease.

Marine Conservation Society calls for better regulation of how north-east Atlantic mackerel is caught as stocks decline

Mackerel populations are declining because of overfishing and the fish no longer a sustainable food choice, the Marine Conservation Society has said in its new UK guide to sustainable seafood.

North-east Atlantic mackerel has been considered an environmentally-friendly choice for consumers since before 2011, but the species has become increasingly scarce and now experts are calling for more regulation over how its caught.

Political and Indigenous leaders hope to replicate success of British Columbia’s Great Bear Rainforest conservation area

Nearly a decade ago, Canadian political leaders, environmental activists and Indigenous nations came together to shelter a sprawling 6.4 million-hectare area of trees, sea wolves, salmon and grizzly bears – a project that was named, with some branding acumen, the Great Bear Rainforest.

The plan has since been hailed as a triumph for protecting swathes of old-growth cedar and spruce and drawing global attention to an area of pristine forest the size of Ireland.

Company rebuts claims by scientists that ‘uncontrolled and unscientific’ practices highlight dangers of going ahead with seabed mining

Video footage from a deep-sea mining test, showing sediment discharging into the ocean, has raised fresh questions about the largely untested nature of the industry, and the possible harms it could do to ecosystems as companies push to begin full-scale exploration of the ocean floor as early as this year.

The Metals Company (TMC), a Canadian mining firm that is one of the leading industry players, spent September to November of last year testing its underwater extraction vehicle in the Clarion Clipperton Fracture Zone, a section of the Pacific Ocean between Mexico and Hawaii.

Retailer and green groups warn of ‘high environmental cost’ of fish aggregating devices to tuna stocks and other endangered marine life

The EU is under pressure to significantly restrict its huge fleet of fishing vessels from using “fish aggregating devices” that make it easier to catch huge numbers of fish and contribute further to overfishing.

A letter signed by Marks & Spencer and more than 100 environmental groups, including the International Pole and Line Foundation, warns EU officials that the devices (FADs) are one of the main contributors to overfishing of yellowfin tuna in the Indian Ocean, because they catch high numbers of juveniles.

Food, feed and fuel: global seaweed industry could reduce land needed for farming by 110m hectares, study finds

Posted on by

Scientists identify parts of ocean suitable for seaweed cultivation and suggest it could constitute 10% of human diet to reduce impact of agriculture

An area of ocean almost the size of Australia could support commercial seaweed farming around the world, providing food for humans, feed supplements for cattle, and alternative fuels, according to new research.

Seaweed farming is a nascent industry globally but the research says if it could grow to constitute 10% of human diets by 2050 it could reduce the amount of land needed for food by 110m hectares (272m acres) – an area twice the size of France.
