Poseidon Water sought to turn seawater into drinking water but activists said plan would devastate ecosystem on Pacific coast
A California coastal panel on Thursday rejected a longstanding proposal to build a $1.4bn seawater desalination plant to turn Pacific Ocean water into drinking water as the state grapples with persistent drought that is expected to worsen in coming years with climate change. Continue reading
From high-protein food to plastics and fuel, Swedish scientists are attempting to tap the marine plant’s huge potential
You can just see the buoys of the seafarm,” Dr Sophie Steinhagen yells over the high whine of the boat as it approaches the small islands of Sweden’s Koster archipelago. The engine drops to a sputter, and Steinhagen heaves up a rope to reveal the harvest hanging beneath: strand after strand of sea lettuce, translucent and emerald green. Continue reading
We care about octopus for many reasons and there is plenty to learn about why. This article will make you want to know more about these creatures. Sy Montgomery, writing in Orion Magazine, is the best illuminator:
Inside the mind of the octopus
ON AN UNSEASONABLY WARM day in the middle of March, I traveled from New Hampshire to the moist, dim sanctuary of the New England Aquarium, hoping to touch an alternate reality. I came to meet Athena, the aquarium’s forty-pound, five-foot-long, two-and-a-half-year-old giant Pacific octopus. Continue reading
Yesterday’s dramatic photograph at sea shows an interaction between two sea creatures, and combines stark beauty with the occasional terror of pure nature. Man and nature in conflict at sea is not beautiful in any manner. This article below, authored by Nick Rahaim and published in Hakai Magazine, helps put the video above in context. Please click the title to read the story in full at its origin, or listen to it here:
As a commercial fisher, I’ve watched colleagues shoot at whales looting from their lines. Here’s why everyone loses when that happens.
It seems a minor request, asking the companies whose ships pass through Sri Lanka’s waters to be considerate of the whales who live in those waters:
Unique colony of blue whales increasingly at risk from tankers and container ships, say marine campaigners
It’s rare that a tiny country like Nauru gets to determine the course of world events. But, for tangled reasons, this rare event is playing out right now. If Nauru has its way, enormous bulldozers could descend on the largest, still mostly untouched ecosystem in the world—the seafloor—sometime within the next few years. Hundreds of marine scientists have signed a statement warning that this would be an ecological disaster resulting in damage “irreversible on multi-generational timescales.” Continue reading
If you have visited Costa Rica, or been fortunate enough to live here, you might have already become entangled with the country’s many opportunities to support conservation. For many decades foreigners have been welcomed to join in the country’s marine and terrestrial conservation initiatives. Many of those foreigners adopt the country as home after getting entangled in all kinds of good ways.
The first eight minutes of the video above are bliss: several young people are introduced, each of whom has become entangled. Along with those introductions, some stunning photography and videography showcasing Costa Rica’s nature, helping you to understand the entanglement. At 8:14 you see the dictionary definitions of entangled. The next 17 minutes are a case study in industrial fishing’s unintended consequences. Not surprisingly, this has already received lots of awards, but they ask you to share freely, so please do. And if you want to support financially, that will be appreciated as well.
When someone offers to point out bright spots on anything in the natural world, we are all ears. When the author is Nicola Jones, all the more:
The first-ever report on the world’s coral reefs presents a grim picture, as losses mount due to global warming. But there are signs of hope — some regions are having coral growth, and researchers found that corals can recover if given a decade of reprieve from hot water.
When ecological genomicist Christian Voolstra started work on corals in Saudi Arabia in 2009, one of the biggest bonuses to his job was scuba diving on the gorgeous reefs. Things have changed. “I was just back in September and I was shocked,” says Voolstra, now at the University of Konstanz in Germany. “There’s a lot of rubble. The fish are missing. The colors are missing.” Continue reading
Whale stories have been in our pages on a regular basis over the last ten years not only because of their charisma. Because of how long they have been on the planet, their future should matter to mankind. The biggest of the species hiding in plain sight is increasingly spotted in ancestral waters, which seems like good news, but read on:
Some experts fear climate crisis is leading creatures back to area where they were hunted almost to extinction
Blue whales, the world’s largest mammals, are returning to Spain’s Atlantic coast after an absence of more than 40 years.
The first one was spotted off the coast of Galicia in north-west Spain in 2017 by Bruno Díaz, a marine biologist who is head of the Bottlenose Dolphin Research Institute in O Grove, Galicia. Continue reading
Thanks to Robert Moor for these reviews:
Two new books, Edith Widder’s “Below the Edge of Darkness” and Helen Scales’s “The Brilliant Abyss,” explore the darkest reaches and all that glows there.
In the deep sea, it is always night and it is always snowing. A shower of so-called marine snow — made up of pale flecks of dead flesh, plants, sand, soot, dust and excreta — sifts down from the world above. When it strikes the seafloor, or when it is disturbed, it will sometimes light up, a phenomenon known, wonderfully, as “snow shine.” Vampire squids, umbrella-shaped beings with skin the color of persimmons, float around collecting this luminous substance into tiny snowballs, which they calmly eat. They are not alone in this habit. Most deep-sea creatures eat snow, or they eat the snow eaters.
Until fairly recently, it was widely believed that the deep seas were mostly devoid of life. For centuries, fishermen hauled in deep-sea trawling nets filled with slime, not knowing that these were carcasses. Some animals, adapted to the pressure of the deep, are so delicate that in lighter waters a mere wave of your hand could reduce them to shreds. The myth of the dead deep sea, known as the Abyssus Theory, was disproved by a series of dredging and trawling expeditions in the 19th century, including a German scientific expedition in 1898 that pulled up the first known vampire squid. But the misconception nevertheless lingered. In 1977, a geologist piloting a submersible near the mouth of a hydrothermal vent, and finding it swarming with creatures, asked the research crew up above, “Isn’t the deep ocean supposed to be like a desert?” Continue reading
In an interview with Yale Environment 360, marine biologist Edith Widder talks about her pioneering research into the world of bioluminescent organisms in the deep oceans and warns of the dangers, from trawling to oil drilling, that imperil this hidden realm.
Until recently, the depths of the world’s oceans remained almost entirely unexplored. But advances in submersible technology are increasingly giving scientists a window into this little-known universe. One of the leaders in this exploration is marine biologist Edith Widder, who has extensively studied bioluminescent, or light-producing, organisms that use this trait to communicate, defend themselves, and hunt in darkness. Among other things, Widder has worked with engineers to develop highly sensitive deep-sea light meters and special cameras, like the remotely operated Eye-in-the-Sea, which allow for real-time monitoring of the seafloor.

As more and more households and businesses and governments plan their switch to electric vehicles, considering the ripple effects is as important now as it was in the age of fossil-fueled vehicles:
The electric vehicle boom is driving a surge in demand for prized metals needed for batteries and other components. Some companies say the solution lies in mining the deep oceans, but scientists say that could irreversibly damage a vast, largely pristine ecosystem.
Nauru, lying about halfway across the vast expanse of the Pacific Ocean between Australia and Hawaii, is the world’s smallest island nation. But in the emerging industry of deep-sea mining, it punches far above its weight.
This June, Nauru gave notice to the International Seabed Authority (ISA), the UN agency charged with regulating mining in international waters, that it was triggering the so-called two-year rule: The agency will have to consider any application for a deep-sea mining license two years from now, under whatever regulations are on the books at the time. This effectively forces the ISA’s hand to finalize a regulatory mining code before that deadline. With this latest development, a once-fanciful idea may soon become a global industry.

It’s been a couple months since we asked anyone the fundamental question. Ok, we acknowledge our not being qualified to make the scientific judgement on whether the Great Barrier Reef is in sufficient danger to be listed as such, officially. But UNESCO has the qualified scientists, so let them do their job without undue influence. It sure seems likely to help the entire world to see how fossil-fueled climate change is impacting such natural wonders. It would raise consciousness in a way that might even be good for Australia–whose government obviously thinks otherwise. Hopefully UNESCO will stick to its principles and resist this lobbying. When oil-based economies come to lend a hand, watch out for conflict of interest:
Exclusive: oil rich nations back push against Unesco recommendation to have reef placed on world heritage ‘in danger’ list Continue reading
Thanks to the Nature Conservancy’s Cool Green Science website for this:
Bivalve and seaweed farming systems result in measurable increases in fish and invertebrate abundance and diversity, new research from The Nature Conservancy, University of New England, University of Melbourne, and the University of Adelaide finds. Continue reading
Thanks, Damian Carrington, for getting us the data that Morales-Caselles et al compiled making us wonder whether convenience is worth this cost:
Just 10 plastic products make up 75% of all items and scientists say the pollution must be stopped at source
Plastic items from takeaway food and drink dominate the litter in the world’s oceans, according to the most comprehensive study to date. Continue reading
Thanks to YaleE360 for this brief explanatory note on Blue Carbon Projects from a Colombian perspective:
A mangrove preservation project along Colombia’s Caribbean coast is using a more comprehensive method to calculate how much carbon is stored in coastal and marine ecosystems, potentially boosting global efforts to conserve so-called blue carbon. Continue reading
Seagrasses, mangrove forests, and coastal wetlands store vast amounts of carbon, and their preservation and restoration hold great potential to bank CO2 and keep it out of the atmosphere. But can the blue carbon market avoid the pitfalls that have plagued land-based programs?
Off the shores of Virginia, vast meadows of seagrass sway in the shallow waters. Over the past two decades, conservation scientists have spread more than 70 million seeds in the bays there, restoring 3,600 hectares (9,000 acres) of an ecosystem devastated by disease in the 1930s. The work has brought back eelgrass (Zostera marina) — a keystone species that supports crustaceans, fish, and scallops, and is now absorbing the equivalent of nearly half a metric ton of CO2 per hectare per year.

They’re purple, spiky and voracious, and just off the West Coast, there are more of them than you can count.
Purple sea urchins have exploded in recent years off California, covering the ocean floor in what divers describe as a “purple carpet.” Continue reading
Thanks to Katherine J. Wu for this, especially for sharing the recordings of the whale song, and the musical reference for how to think about the difference between this whale population’s song and the that of other whale populations:
The whales in the group seem to sing a unique song.
Weighing up to 380,000 pounds and stretching some 100 feet long, the blue whale — the largest creature to have ever lived on Earth — might at first seem difficult for human eyes and ears to miss.
But a previously unknown population of the leviathans has long been lurking in the Indian Ocean, leaving scientists none the wiser, new research suggests. Continue reading
Wonderful news out of Belize!
For a country that’s slightly smaller than the U.S. state of Massachusetts, Belize boasts an inordinate number of ocean wonders. It’s home to the world’s second longest barrier reef, which Charles Darwin once described as “the most remarkable reef in the West Indies.” Here, you’ll find more than 500 unique fish species – enough to give every Belizean island its own mascot and still have about 50 left over.
Because this little Caribbean country has a lot worth protecting, it has enacted some of the strongest ocean conservation laws in the world – and they just got even stronger. Following hard-fought victories that banned all trawling and offshore oil drilling in Belize’s waters, the country has now outlawed gillnets, a fishing gear that kills turtles, manatees, and many other marine animals.
In addition to implementing a nationwide gillnet ban, the Belizean government signed an agreement with Oceana and the Coalition for Sustainable Fisheries to help licensed gillnet fishers transition to other jobs. As a result, Belizean resources and livelihoods will be protected well into the future.
As Janelle Chanona, Oceana’s head in Belize, put it: “This is a historic moment for Belize, her people, the Caribbean Sea and, most importantly, for everyone who depends on the country’s marine resources for their livelihoods.” Continue reading
