Turtle concern: Australian businessman denies threatening to sell Conflict Islands to China

Ian Gowrie-Smith says he was frustrated the Australian government did not respond to urgent funding request for turtle conservation

The owner of 21 tropical islands off the coast of Papua New Guinea says he never threatened to sell them to China and his main aim is to save the turtles that nest there.

Ian Gowrie-Smith, an Australian businessman and investor, bought the Conflict Islands, which lie less than 1,000km from the Australian coast, almost two decades ago.

‘Alien goldfish’ may have been unique mollusc, say scientists

Researchers think they may have solved enduring mystery of where Typhloesus wellsi sits on tree of life

The mystery of a bizarre creature dubbed the “alien goldfish”, which has baffled fossil experts for decades, may have been solved, according to scientists who say the animal appears to have been some sort of mollusc.

Typhloesus wellsi lived about 330m years ago and was discovered in the Bear Gulch Limestone fossil site in Montana in the late 1960s, with the remains of other species subsequently identified.

Antarctic researchers gain insights from on high as they count seals from space

Scientists used satellite images and more than 300,000 volunteers to count Weddell seals, a key Southern Ocean indicator species

Researchers believe they have accurately estimated Antarctica’s Weddell seal population for the first time – using images from space and the eyes of hundreds of thousands of citizen scientists.

Weddell seals are a key indicator species in the Southern Ocean, for both sea ice fluctuations and shifts in the food web. They can live up to 30 years in the harsh conditions of the coastal sea ice of Antarctica, but until recently, counting them has been risky and cost-prohibitive.

EU slammed over failure to protect marine life from ‘destructive’ fishing

Strict no-take policies urged by scientists, who note there is less protection in 59% of marine protected areas than outside MPAs

The waters of the EU are in a “dismal” state, with only a third of fish populations studied in the north-east Atlantic considered to be in good condition, according to more than 200 scientists and conservationists.

The analysis, issued on Monday, follows a scathing report from the European court of auditors two years ago, which warned that the EU had failed to halt marine biodiversity loss in Europe’s waters and to restore fishing to sustainable levels.

‘We just want the truth’: British coastal towns fight for answers over mystery sealife deaths

Question mark over freeport in Tees Valley after ecological disaster puts communities in the north east of England at loggerheads with the government

Stan Rennie has indelicate hands that aren’t good for typing. He’s not the kind of person who cares much for technology at all.

But over the last year, the fisherman has found himself spending less time outdoors and more time glued to his computer, tapping out stern emails to politicians and researching niche areas of environmental law. “It’s taken over his life,” his daughter Sarah, 36, says.

Thousands of dead fish wash up in Oakland lake to create a putrid mess

Experts, concerned about the algae bloom that is turning the water to brown muck, say the die-off is ‘like losing giant redwoods’

Thousands of fish carcasses have been floating up to the edges of the San Francisco Bay, and the scummy top of Oakland’s Lake Merritt – stewing under the sun and wafting a putrid stench into nearby neighborhoods.

The dead bat rays, striped bass, sturgeon, anchovies and clams, are likely mass victims of an algal bloom that scientists are racing to understand. In the meantime citizen scientists, local photographers, joggers and naturalists have been capturing dramatic photos of the die off.

‘The blue flags are proof’: how Greece cleaned up its act on sewage

Greeks take their seas seriously, with the construction of one of the world’s biggest sewage treatment plants a real game-changer

The shimmering waters along the Athenian riviera offer a welcome respite in the summer heat. In one of Europe’s most congested cities the sight of ever more beaches attaining blue flag status – a mascot of water quality – has heightened the sense of relief that the coastal location affords. For those who flock to its coves, rocks and sandy stretches, the shoreline that extends from the Greek capital’s southern suburbs has become the perfect antidote to the rising temperatures that have accompanied climate breakdown.

It was not always so.

After 350 years, sea gives up lost jewels of Spanish shipwreck

Marine archaeologists stunned by priceless cache long hidden beneath the Bahamas’ shark-infested waters

It was a Spanish galleon laden with treasures so sumptuous that its sinking in the Bahamas in 1656 sparked repeated salvage attempts over the next 350 years. So when another expedition was launched recently, few thought that there could be anything left – but exquisite, jewel-encrusted pendants and gold chains are among spectacular finds that have now been recovered, having lain untouched on the seabed for hundreds of years.

The Nuestra Señora de las Maravillas (Our Lady of Wonders) went down on the western side of the Little Bahama Bank, over 70km offshore, but the newly discovered treasures were found across a vast debris trail spanning more than 13km.
