Adam Fox grabbed the nets and the cage from the back of his pickup truck. Something in the sand was disturbing the iconic Southern California scenery at the Santa Monica Pier on Friday morning. A sea lion washed up on the beach just north of the Ferris wheel. It was alive but gravely ill and in a disoriented, near-comatose state. On the other side of the pier, another sea lion lay in the sand, a little more alert but still sick. Mr. Fox, who works for a sea-mammal rescue group, rushed to help save the animals and transport them to get treated. Both sea lions were given ID numbers, which told a story. They were tagged as 25-193 and 25-195 — the group’s 193rd and 195th patients of the year. All along the Southern California coastline from San Diego to Santa Barbara, hundreds of animals — sea lions, dolphins, seabirds — are washing up on the sand either dead or seriously ill. Coastal researchers and officials say it’s become a marine-life crisis that has overwhelmed rescue organizations, distressed beachgoers and hurt California’s ocean habitat. The cause is a neurotoxin produced by an algae bloom. The toxin, known as domoic acid, is harmless to fish but can be deadly to sea mammals. Fish carry the toxin, but if mammals and birds eat the fish, the toxin can poison them, causing seizures, making them behave erratically or putting them in a coma. The only treatment is to flush out the toxin and medicate the symptoms. Algal blooms are not rare in California, but the amount of toxic acid the blooms have been releasing and the scale of harm they have been causing to sea life have puzzled scientists. “We’ve been seeing more toxin both in the organism itself and then also in the animals that are acquiring it,” said Clarissa Anderson, the director of the Southern California Coastal Ocean Observing System, which monitors ocean conditions. “They seem to have more toxin in their tissues. So it may be that the naturally occurring plankton is starting to produce more toxin over time, and that might be why we see more impacts.”

We are heading to Maui in early April. Will be staying at a family resort about 15 minutes north of Lahaina. I hope to get away for a bit of diving one day. I'm hoping to find a shop/guide that can get me to the most picturesque couple of sites. I think that would be a boat dive but I don't know Maui so maybe that would be a shore dive. Looking for recommendations and/or comments. Thanks, Brian Handly

A 4 part series in dive magazine from survivors of the Sea Story Egypt sinking. Turns out there were several warning signs about how badly prepared the boat and crew were beforehand. Regina https://divemagazine.com/scuba-diving-news/sea-story-liveaboard-survivor-tells-her-story

Amazing story. Great mixed media production too. This is a gift article - hopefully will open up without a paywall. https://www.nytimes.com/interactive/2025/03/12/magazine/russia-arctic-fossils-expedition.html?rsrc=flt&unlocked_article_code=1.3k4.mWVK.llI0OjdioUYV&smid=url-share - Eric Elia

Begin forwarded message: From: Regina Roberts <reginarobertspta@...> Date: March 11, 2025 at 2:51:14 PM PDT To: Ba-diving <[email protected]> Subject: Travel insurance ?I had planned a trip for 2 years to Raja leaving this February 2025 and a week before ended up in the hospital and being told I couldn’t travel. I purchased the additional travel insurance from DAN who uses Generali. They have been a bit slow but once they get the documents they need they pay right then into your bank account. Highly recommend especially with how expensive these trips are. The air from SFO to Jakarta is a problem as I didn’t cancel it before the trip, turns out even though non refundable they would have given me a credit since it was medical. But everything else covered so I am happy. My 2 cents. Regina

SciTechDaily article on free-living coral and its propulsion method (among other rather interesting things.) https://scitechdaily.com/breaking-the-rules-free-living-coral-stuns-scientists-by-swimming-straight-toward-blue-glow/ jky

This vid documents an ambitious underwater model shoot: https://www.dpreview.com/articles/8554894828/photographer-dives-to-new-depths-for-record-breaking-image?mc_cid=06fd954cf9&mc_eid=0f22afeedd Allegedly the entire dive was only 51 minutes! The vid doesn't mention decompression precautions, gas choices, participants' backgrounds, or lots of other potentially interesting details, but it was a very cool project. /Rick -- Rick Tavan Truckee and Saratoga, CA

I'm cleaning out barely used UW equipment. I haven't been diving for >10 years. Available: Ikelite Flash DS 50 with remote sensor, grip bracket and several bracket pieces. Kowalski Speed UW light with charger. The battery is likely dead from old age but can be replaced AFAIK. CP-4Pro UW camera case, don't remember the brand or the camera it fits. All available to pick up for free in East Bay. Message me.

Humpback Whales Sing the Way Humans Speak The animals’ complex songs share structural patterns with human language that may make them easier for whales to learn, a new study suggests. The words in heaviest rotation are short and mundane. And they follow a remarkable statistical rule, which is universal across human languages: The most common word, which in English is “the,” is used about twice as frequently as the second most common word (“of,” in English), three times as frequently as the third most common word (“and”), continuing in that pattern. Now, an international, interdisciplinary team of scientists has found that the intricate songs of humpback whales, which can spread rapidly from one population to another, follow the same rule, which is known as Zipf’s law. The scientists are careful to note that whale song is not equivalent to human language. But the findings, they argue, suggest that forms of vocal communication that are complex and culturally transmitted may have shared structural properties. https://www.nytimes.com/2025/02/06/science/language-humpback-whale-song.html?unlocked_article_code=1.vE4.LUin.-EauDWo32pz8&smid=em-share

I've got a leaky dry suit. And a problem: I can't get seem to get it fixed. Here's why. I bought the suit from OS Systems up in Scappoose, Oregon and had Frank Copren modify it by installing silicone neck and wrist seals. Silicone seals require installing a hard plastic ring for each seal since you can't glue silicone seals directly to a suit. The ring lets you swedge the seal in place, and makes it easy to replace the seals if they fail. This last year the suit developed a chest leak that I couldn't locate with my own inflate/soapy water testing. I sent it to Cricket at Otter Bay who was able finally, after a lot of effort, to find a slight zipper leak, but wasn't able to replace the zipper because the dry suit required materials she didn't have. So: I contacted OS Systems to replace the zipper, but they won't because they say they have to test the suit after replacement. They can't test because they turn the suit inside out to inflate it and test it in water, and seal rings make it impossible to turn the suit inside out. And they refuse to replace the zipper if they can't test it the way they want. Silicone seals are common these days, so I imagine there are solutions to this problem. Does anyone on this knowledgeable list have ideas? Saving dry wit for an occasion when I'm actually diving dry, Mike Boom
