I had to read to the end to see Paul Watson’s name, and more importantly his proclamation on the significance of Japan’s withdrawal. It has been a long time since we have seen him or Sea Shepherd in our pages. My thanks to Daniel Victor and his employer for this important story:
Japan said on Wednesday that it would withdraw from an international agreement and resume commercial whaling, a defiant move to prop up an industry that still has cultural significance there, despite plummeting demand for whale meat.
Yoshihide Suga, Japan’s chief cabinet secretary, said the country would leave the International Whaling Commission, which established a moratorium on hunting whales that took effect in 1986.
The international agreement never stopped Japanese whaling, because it allowed the country to continue killing whales for scientific research while selling the meat. Critics considered the research a sham, little more than a cover for commercial whaling. Continue reading

Thanks to National Public Radio for this:
Amid a sea of dire climate change news, researchers say they’ve found a rare bright spot.
A meadow of seagrass among Australia’s Great Barrier Reef — estimated to be twice the size of New Jersey — is soaking up and storing carbon that would otherwise contribute to global warming.
Scientists call this carbon-removal powerhouse a “blue carbon sink.” The term refers to an ocean or coastal ecosystem — including seagrasses, salt marshes and mangrove forests — that captures carbon compounds from the atmosphere, effectively removing carbon dioxide, a known greenhouse gas that contributes to climate change.

Just five countries hold 70% of the world’s remaining untouched wilderness areas and urgent international action is needed to protect them, according to new research.
Researchers from the University of Queensland (UQ) and the Wildlife Conservation Society (WCS) have for the first time produced a global map that sets out which countries are responsible for nature that is devoid of heavy industrial activity.
It comes ahead of the conference of parties to the Convention on Biological Diversity in Egypt in November where signatory nations are working towards a plan for the protection of biodiversity beyond 2020.
Conservationists are calling for a mandated target for wilderness conservation that will preserve the planet’s vulnerable ecosystems. Continue reading

These creatures have been around forever, more or less. Survived everything that nature threw at them over the epochs. Until mankind and its addiction to plastic. And now it is clear their days are numbered, so any initiative anywhere that tries to slow the clock and keep the species going, we are happy to hear about it and share on this platform. Thanks to Amy Yee for bringing this to our attention:
An organization on the coast of Kenya tries to persuade local residents to help return the trapped reptiles to the ocean, rather than sell their meat and shells for a living.

WATAMU, Kenya — The young hawksbill turtle was accidentally caught in a net in the Indian Ocean off Kenya’s coast.
The fisherman called Local Ocean Conservation, a nonprofit based in the town of Watamu that is the only turtle rescue and rehabilitation center on the East African seaboard. The hawksbill, critically endangered in this region, was a mere seven pounds; adults can weigh up to 160 pounds.
X-rays showed that the reptile’s intestinal tract was clogged with plastic. Hogaar, as Local Ocean named her, floated and couldn’t dive. Gas had built up in her innards after she had eaten small pieces of plastic mistaken for food such as jellyfish. Local Ocean staff members placed Hogaar in a rehab pool and gave her laxatives. She passed feces laced with shreds of packaging and had little appetite. After more than four months at Local Ocean, Hogaar died. A necropsy revealed her gut was also full of sharp shards of white, blue and pink plastic and tangles of blue and gray string.
Turtles are reptiles that have existed for at least 110 million years and survived the mass extinction that killed off dinosaurs. But today, sea turtles worldwide are threatened with extinction. And it’s estimated that only one of 1,000 turtle eggs laid survive to adulthood. Continue reading
Thanks to Michelle Nijhuis, whose science writing we have been following since 2014 but up to now mostly in another magazine we source from; this is as fine as it comes:
Valérie Chamberland swims like a dolphin, quickly and fluidly, and for most of the past hour she has been darting through the warm, shallow water off the Caribbean island of Curaçao. Now, she is dangling upside down, hovering above a pillow-sized brain coral. Her rubber fins twitch steadily overhead, and as she sips air from the aluminum tank on her back, a stream of bubbles rises from her regulator’s mouthpiece.
The reef spread below Chamberland isn’t one of those flashy, fluorescent gardens seen in calendar photos and nature documentaries. Only a few dozen yards from shore, it lies almost literally in the shadows of a stone jetty, a busy casino, and a Denny’s restaurant. The waters that surround it are murky, and most of its corals are brown and lumpy, sparsely accessorized with bright-purple vase sponges and waving, rusty-red sea fans. Continue reading
Thanks to Christina Caron for this story that raises important questions about an awesome-sounding technology. Best to first read from The Ocean Cleanup website, and if you have been following the stories we pay attention to you will understand how we might get hooked on the idea:
Ocean garbage patches are vast and dispersed
Ocean currents concentrate plastic in five areas in the world: the subtropical gyres, also known as the world’s “ocean garbage patches”. Once in these patches, the plastic will not go away by itself. The challenge of cleaning up the gyres is the plastic pollution spreads across millions of square kilometers and travels in all directions. Covering this area using vessels and nets would take thousands of years and cost billions of dollars to complete. How can we use these ocean currents to our advantage?
THE IMPACT OF CLEANUP
Our models indicate that a full-scale system roll-out could clean up 50% of the Great Pacific Garbage Patch in 5 years.
Research shows the majority of plastic by mass is currently in the larger debris. By removing the plastic while most of it is still large, we prevent it from breaking down into dangerous microplastics.
Combining the cleanup with source reduction on land paves the road towards a plastic free ocean by 2050.
The story in the New York Times raises important questions, not least of which is that Peter Thiel is involved:
…But the ocean can be unpredictable, and simulation models are no guarantee of future performance.
“There’s worry that you can’t remove the plastic without removing marine life at the same time,” said George Leonard, chief scientist at the Ocean Conservancy. “We know from the fishing industry if you put any sort of structure in the open ocean, it acts as a fish-aggregating device.” Continue reading

Diminutive bonnethead sharks are the first omnivorous sharks known to science, which could change our understanding of what some sharks eat.

Sharks are not known for their taste for greenery. But at least one species of shark enjoys a salad of sea grass as well as the prey it hunts.
The bonnethead shark, a diminutive species that reaches up to 3 feet in length, lives in the shallow sea grass meadows off both coasts of the Americas. It eats small squid and crustaceans ferreted from the swaying underwater fronds. But, researchers who have carefully monitored everything going in and out of captive bonnetheads say in a study published in Proceedings of the Royal Society B that they also eat large quantities of seagrass. The grass isn’t just passing inertly through the sharks’ guts. They extract nutrition from it just as they do from the meaty portion of their diet. These sharks must, therefore, be reclassified as omnivores — the first omnivorous sharks known to science. Continue reading
This National Public Radio (USA) story led us to the video above, and then the source website, where we discovered several initiatives that are worth a closer look:
Ocean action: In 2017, Carmel-by-the-Sea’s City Council voted to require that restaurants stop using single-use plastic straws and utensils and instead provide only compostable to-go serviceware—and only upon request. The law took effect in the spring of 2018. The impetus came from a group of fifth-grade students from Carmel River Elementary School. They spoke at community forums and Carmel City Council meetings to advance the idea. Mayor Steve Dallas later credited them with playing a pivotal role in getting the ordinance enacted. “When it finally passed, the students were ecstatic,” says teacher, Niccole Tiffany, of her students. “It was a big lesson on the power of kids’ voices in actively creating change.” (Read more of her story here)
Thanks to the Monterey Bay Aquarium for programs that inspire local citizens, especially youth, to environmental activism like this:
Ocean action: Shelby O’Neil, a high school student from San Juan Bautista, created a successful campaign called “No Straw November,” asking people to pledge not to use plastic straws for one month. She’s earned national exposure through the Martha Stewart Living magazine and the Leonardo DiCaprio Foundation. She convinced Alaska Airlines to ditch plastic straws and toothpicks on all its flights (a story picked up by Fortune magazine). Shelby was even flown to the headquarters of Delta Airlines to promote her campaign; spoke at Dreamforce, the annual user conference hosted by Salesforce.com in San Francisco; and won unanimous California Coastal Commission support for “No Straw November.” But she didn’t stop there. “For a Girl Scout Gold Award, I created a nonprofit called Jr Ocean Guardians,” says Shelby, “teaching younger schoolchildren the importance of the oceans and how they can help.” Continue reading

If you are trying to watch what you eat for sustainability and impact, Justin McCurry, in Tokyo writing for the Guardian, has this story to keep in mind:
Low light imaging data being used to expose unregulated and unreported fishing on the high seas
New data is being used to expose fleets of previously unmonitored fishing vessels on the high seas, in what campaigners hope will lead to the eradication of illegal, unregulated and unreported fishing.
Global Fishing Watch (GFW) has turned low light imaging data collected by the US National Oceanic and Atmospheric Administration (NOAA) into the first publicly available real-time map showing the location and identity of thousands of vessels operating at night in waters that lie beyond national jurisdiction.

Ford does what it thinks to be in the best interest of its shareholders, and other companies follow suit as they sense the opportunity to do so, reducing their environmental responsibilities. Meanwhile and nonetheless, thanks to the work of organizations like WWF and Greenpeace, we have the opportunity to witness, if from afar, the rebirth of a population that signals some intact corners of the earth’s environment:

In a rare piece of good news for whales, humpbacks who live and breed in the southern oceans near Antarctica appear to be making a comeback, with females in recent years having a high pregnancy rate and giving birth to more calves.
Humpback whales were nearly hunted out of existence in the late 19th and most of the 20th centuries until treaties were signed to stop killing them and protections were put in place for the world’s coldest, least accessible continent.
The end of hunting has fostered the recovery of the school-bus-sized animals whose life spans are roughly comparable to ours, according to Ari Friedlaender, an associate researcher at the University of California Santa Cruz, who led the new study.
The population was believed to have been reduced to less than 10 percent of it pre-whaling levels. Continue reading

Thanks to Marguerite Holloway, who we have appreciated a couple times earlier, for this:
One foggy morning last April, a dead humpback whale washed up on New York’s Rockaway Beach. It was a young male, thirty-one feet long, and had extensive bruising—the result of contact with “something very large,” according to Kimberly Durham, of the Atlantic Marine Conservation Society, who performed the necropsy. The Rockaway whale was one of sixty-eight humpbacks that have died between North Carolina and Maine since 2016, casualties in what the National Oceanic and Atmospheric Administration is calling an “unusual mortality event.” And humpbacks, it turns out, are not the only species suffering.

Thanks to for this story about how a Robotic Fish Moves Like The Real Thing — So It Can Observe The Real Thing:
SoFi, the robotic fish, swims in for its close-up. MIT computer scientists hope SoFi will help marine biologists get a closer (and less obtrusive) look at their subjects than ever before. MIT CSAIL
Scientific advancement: It’s all in the wiggle.
OK, it’s a lot more complicated than that. But when a team of researchers at MIT unveiled their robotic fish Wednesday, one of the keys they emphasized was the graceful undulation of the prototype’s tail — which, besides being rather eye-catching, serves a crucial role in the robot’s ultimate mission: giving scientists the ability to unobtrusively observe marine wildlife remotely.
“Because the fish moves through undulating movement rather than thrusters, the impact it has on how the water moves around it is much more like what is expected of physical fish,” Daniela Rus, director of the school’s Computer Science and Artificial Intelligence Lab, tells NPR. Continue reading
Our favorite stories on conservation challenges–whether marine or terrestrial–are those that highlight entrepreneurial approaches. Those stories, though, have multiple counterparts related to government approaches to conservation. In our many celebrations of various forms of ocean conservation, we have probably tended to favor quantity and scale more than emphasizing the value of science. Guilty as charged, but ready to remedy:
SAN FRANCISCO — I have spent my entire life pushing for new protected areas in the world’s oceans. But a disturbing trend has convinced me that we’re protecting very little of real importance with our current approach.
From Hawaii to Brazil to Britain, the establishment of large marine protected areas, thousands of square miles in size, is on the rise. These areas are set aside by governments to protect fisheries and ecosystems; human activities within them generally are managed or restricted. While these vast expanses of open ocean are important, their protection should not come before coastal waters are secured. But in some cases, that’s what is happening.

“What does your husband do while you’re working on the seaweed lines?”, we ask. She laughs and says in Bahasa, “He does the cooking and the cleaning.”
It’s day 6 of our field visit to Indonesia and we’re in Takalar visiting our fifth island and third seaweed farm of the trip. On the brink of the ‘extreme season,’ stifling hot is an understatement, but the light breeze from the Flores Sea provides a welcome break from the three flights and 2-hour van trip that brought us here.

The four Colombian exchange delegates with Phil Karp and Jen Chapman, Blue Ventures’ Country Coordinator in Belize.
As in other fields of capacity building for development there is a growing recognition within the marine conservation community of the power of practitioner–practitioner exchange. Whether they take the form of ‘barefoot’ exchanges between fishers, or more formal exchanges involving Marina Protected Area (MPA) managers and policymakers, such exchanges are emerging as an extremely effective way of sharing, replicating, adapting and scaling up successful solutions to the challenges of marine protection and avoiding repetition of unsuccessful approaches. Practitioner exchanges are particularly effective for sharing ‘how to’ or tacit knowledge about solutions, as such tips and tricks tend not be fully recorded in written descriptions or case studies.
Practitioner exchange as a form of capacity building represents a departure from more traditional approaches such as technical assistance or deployment of expert advisors. In the latter case, external experts are relied on to share successful solutions with which they are familiar only through research, and may therefore lack a complete understanding of the full range of factors and potential pitfalls that could influence the successful implementation of an approach elsewhere.
Blue Ventures has been very active in practitioner exchanges for some time, focused on sharing its pioneering work on the use of periodic, short-term fishery closures as an effective solution to balancing species conservation and livelihoods. Continue reading
