Sea lions released back into Pacific Ocean as toxic algal blooms move out of Southern California
SAN DIEGO (FOX 5/KUSI) — Scripps scientists have confirmed that the harmful algal blooms (HABs) that have been responsible for sickening hundreds of marine mammals in the Pacific Ocean along the California coast this spring have moved out of the area, and rescue organizations in Southern California have been busy releasing the last of the rehabilitated sea lions.
Scientists with Scripps Institution of Oceanography at UC San Diego report the harmful algal blooms (HABs) that produce domoic acid — which accumulates in fish and shellfish, sickening sea lions, dolphins and birds that eat them, and overwhelming local rescue organizations — are gone.
California sea lions are getting sick, but what's causing it?
SeaWorld San Diego Rescue teams this past spring were getting upwards of 100 calls per day for sea life in need of help as a result of the toxic algal blooms.
According to the County of Los Angeles, four injured sea lion pups — Brownie, Sprinkles, Peachick and Spiderling — that were rehabilitated and cared for by the Marine Mammal Care Center, were recently released at Venice Beach with help from the Los Angeles County Fire Department Lifeguard Division and marine mammal experts.
In San Diego, the SeaWorld San Diego Rescue team said the last seal lion suffering from domoic acid poisoning, and rehabilitated at SeaWorld, was returned to the Pacific Ocean on May 30.

Scripps reports that although the HABs are not in Southern California anymore, they did detect some presence around Santa Cruz in late May.

From mid-February to mid-May, SeaWorld San Diego reports its Animal Rescue Team rescued 69 sea lions and 60 birds suffering from domoic acid symptoms.
Rescue teams were overwhelmed by cases this year, but say marine rescue calls have dropped over the last three weeks.

Vera Rubin Scientists Reveal Telescope's First Images
On Monday, the cosmic curious are getting a first full look at pictures of the universe that reveal the capabilities of the new Vera C. Rubin Observatory. One shows a riotously pink view of the Trifid and Lagoon nebulas. The two sprawling clouds of dust and gas, thousands of light-years away from Earth in the constellation Sagittarius, have been photographed often by both amateurs and professional astronomers. More powerful instruments have taken more detailed photos, but with their narrow field of view, they only see a small slice of the scene. 'You've not seen the whole thing, all captured at once at this depth with so many objects there,' said Steven Ritz, a physicist at the University of California, Santa Cruz, and the project scientist for Rubin construction. 'That, I would point out, is new. And just how pretty it is.' Dr. Ritz hopes this teaser image will pique people's curiosity enough to tune in to a news conference on Monday, June 23, at 11:30 a.m. Eastern time when observatory officials will reveal what they are calling Rubin's 'First Look' images. The Rubin Observatory, a joint venture of the U.S. Department of Energy and the National Science Foundation, will provide a comprehensive view of the night sky unlike anything astronomers have seen before.

Pandemic-era puppies, kittens now filling San Francisco shelters beyond capacity
The COVID-19 pandemic is still having a deadly effect on the pet population. The number of unwanted animals is straining San Francisco's shelter capacity to the breaking point, sometimes with tragic results. Just about every animal shelter in the state is jammed these days and it all points back to the pandemic when shelters were empty and it was hard to find any animal to adopt, as people tried to cope with COVID isolation. But also at that time, spaying and neutering were suspended or drastically reduced. And now those generations of puppies and kittens are filling the shelters. "So, not just in San Francisco, but in California and nationwide, we are like two million spay/neuters behind. So, that just leads to more and more accidental breeding," said Virginia Donohue, Executive Director of San Francisco's Animal Care and Control. "Pre-pandemic, we were full a couple times a year. Now we're full a couple times a month. It is a constant problem. It's no longer an occasional problem." And it can have heartbreaking consequences. SF Animal Care and Control works to find unwanted pets a home, but when none is available, they must turn to euthanasia to make room. "We try very hard to euthanize just for medical and behavior issues," said Donohue. "But there are points when an animal is here too long and nobody is coming for it, we don't have a place for it to go and its behavior is deteriorating. Then we're going to euthanasia." One of the reasons the city's public animal shelter is so full is because its major adoption partner, the San Francisco SPCA, is taking a lot fewer dogs and cats than it used to. The SF SPCA, which is a private entity, has joined forces with the Stockton SPCA and is now rescuing a lot more unwanted pets from the Central Valley. "Historically, they've taken as many as 600 dogs," said SF's Donohue. "Currently, it's under 200. So, obviously, that's a pain point." It's also a reason why Animal Care and Control is having to turn to euthanasia. Another is that the shelter has a "custody" program that holds dogs up to two weeks for people who go to jail or the hospital or who die. That all takes space from those pets looking to be adopted. On Saturday, a dog owner named Ethan said he sometimes wonders where they're all coming from. "To see the amount of people out there that have dogs that aren't taking care of them, like, I don't really understand how they got these dogs in the first place," he said. The dogs are out there, many in desperate need of a caring home. But there is only so much space in the shelters and reducing the population is now more than just a humane thing to do. It's becoming a matter of life and death. "I mean, don't get a dog if you weren't intending to get a dog," Donohue said. "But if you want a dog, just look at your local shelter first. Even if you don't find the dog of your dreams there, just look and see what's available."
