Overfishing and potential solutions have received lots of attention in our pages over the years. It is not a new problem. And yet, we now have better metrics for how serious the problem is and who is responsible, currently, for making the problem worse. The screenshot to the left does not capture the full value of the dynamic illustration accompanying this article. Click the image to go to the source:

How China Targets the Global Fish Supply
With its own coastal waters depleted, China has built a global fishing operation unmatched by any other country.
Rich and ecologically diverse, the waters around the Galápagos Islands have attracted local fishermen for centuries. Now, these waters face a much larger, more rapacious hunter: China. Continue reading
It has been a long time since our last links to a favorite coffee table book publisher. Next month, it could be yours. And inside we see a page with homage to Rudolf and Leopold Blaschka, old favorites:

Yesterday’s post got me looking back at our attention to marine science over the years, making me wonder whether we have given that topic its fair share. Yes, probably, but more is needed. I already knew this name because it has appeared in our pages a few times over the years. But just recently I heard her name from two different people who have had the chance to know her personally. One of them, when I mentioned the name, replied with Her Deepness replacing Sylvia Earle’s given name. Thanks to Dana Goodyear, who had me at puma, but who also knows a thing or two about water, now this:
Do you like to breathe?” This is a question that the marine biologist and deep-sea explorer Sylvia Earle asks frequently. The ocean produces half of the oxygen on Earth. If it dies, humanity can’t survive, so humans better pay attention to it. Continue reading

Lionfish came to our attention in a series of posts starting in 2014. That year we came to see that fighting this invasive species would require innovative entrepreneurial conservation methods. We published more posts and series about initiatives in the years since then, but the problem continued to grow. For some reason the stories about initiatives started fading from our attention and then stopped with a post in 2018. Now, 22 posts since the first post and four years since the last one, lionfish are back in our thoughts thanks to Inversa’s innovation:

There’s only one word for it: indescribable. “It’s one of those awesome experiences you can’t put into words,” says fish ecologist Simon Thorrold. Thorrold is trying to explain how it feels to dive into the ocean and attach a tag to a whale shark — the most stupendous fish in the sea. “Every single time I do it, I get this huge adrenaline rush,” he says. “That’s partly about the science and the mad race to get the tags fixed. But part of it is just being human and amazed by nature and huge animals.”
Whale sharks are one of a select group of large marine animals that scientists like Thorrold, of the Woods Hole Oceanographic Institution in Massachusetts, have signed up as ocean-going research assistants. Continue reading

Desalination, which we celebrated multiple times over the years, might not be all as good we thought it was:
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

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:

When she publishes an essay, or a longform reported article, it should be clear before you start that you are almost certainly not going to enjoy what you learn:
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:
Finding Bright Spots in the Global Coral Reef Catastrophe
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.

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

Nothing like bioluminescence to take your mind off of other things for a while. Thanks to Yale e360 for this:
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:
