Why did four whales wash up in San Francisco Bay in a week and a half?
The juvenile minke whale had been spotted swimming around San Francisco Bay for nearly a week by the time she beached herself off the coast of Emeryville on April 8. Scientists had thought she seemed healthy, but after an examination, they determined she was acting abnormally and had to be euthanized due to illness.
It was the fourth whale death in the San Francisco Bay in a week and a half. The other three were gray whales, the first of which—a 36-foot-long female—washed up at Black Sands Beach in the Marin Headlands on March 30. Its cause of death remains unknown.
On April 2, a deceased adult male gray whale was found floating east of Angel Island; its cause of death is also not known, according to the Marine Mammal Center. Then, a subadult male gray whale washed ashore at Fort Point Rock Beach near the Golden Gate Bridge in San Francisco on April 4, and scientists determined that it likely died due to a vessel strike, according to the mammal center.
Taken together, the deaths have raised the specter of past “unusual mortality events” that caused whales to die in higher-than-normal numbers.
“This is unusual,” said Kathi George, director of Cetacean Conservation Biology at the Marine Mammal Center in Sausalito. “It takes me back to several years ago when we did have a large number of strandings happen at the same time.”
While the unusually high number of whales beaching in such a short span is abnormal, the number of whales who have died around the bay for the year has remained in line with typical levels, scientists say.
“This is the normal time of year when gray whales are doing their northward migration from Mexico up to Alaska, so it’s not uncommon for us to have gray whales in and around San Francisco Bay in April and May each year,” said Moe Flannery, who leads the marine mammal necropsy team at the California Academy of Sciences.
“Although they seem high because they’re concentrated into a short period of time, the numbers of dead and stranded are not any different than the recent previous years.”
Whales can die for “a number of reasons”—from diseases to malnutrition to vessel strikes, George said.
“It’s coincidental that everything happened in a week and a half, but there are a lot of whales out there right now, and some of their physical condition that they’re in when they arrive in the bay may make them more susceptible to human impacts if they’re not as healthy,” she said.
Scientists began observing whales entering the San Francisco Bay around 2016 as they completed their annual migration between Mexico and the sub-Arctic, George said. The whales do not feed while they are in their breeding grounds in Mexico, and expend a lot of energy mating, nursing babies and giving birth before facing a long journey back north to their feeding grounds, she added.
Because of this energy expenditure, scientists have seen the gray whales attempt to feed in new locations—including San Francisco Bay, George said. Their increased appearance in the bay could also potentially be explained as whales seeking a place to rest before continuing the migration, or a reaction to climate change, warming ocean temperatures and prey availability.
The Marine Mammal Center has tracked at least 18 individual whales swimming in the bay this year, and sightings of gray whales have been reported almost every day since mid-March, George said. The majority of the whale sightings have been reported east of Angel Island, said Giancarlo Rulli, the associate director of public relations for the Marine Mammal Center.
Between 2019 and 2023, gray whales were dying in much higher numbers due to an unusual mortality event, which was declared by the National Oceanic and Atmospheric Administration Fisheries. Gray whales lost more than 40% of their population in four years, Rulli said. During this time, there were 347 gray whale strandings in the United States, according to NOAA.
“These whales basically left the Arctic with a half tank,” Rulli said. “The food sources that they were normally accustomed to eating that were highly nutritious for this massive, 10,000–12,000-mile journey, had moved farther away due to climate change, and as a result, these whales were left to forage on food matter that was much less nutritious.”
Between January and April 2019, which was the first year of the unusual mortality event, 34 dead gray whales washed up on California’s coast, Flannery said. Seven have so far this year.
George said that whether the recent deaths could be the start of an unusual mortality event is “still under discussion and review,” adding that the data collected from these strandings will help scientists understand “the bigger picture of what’s happening.”
“We’re not there yet,” she said, adding that scientists have to look at their migratory range holistically.
Whales will continue to appear in the bay through mid-May as they continue their migration north, George said.
Flannery added that anyone using the water “needs to be more aware of the animals that are sharing that environment.”

Latest California-based gig work app lets people book content creators, editors
It’s 10 a.m. sharp, and Abby Kurtz gets her first assignment of the day. She’s received a time, a location in San Francisco and a target.
Her weapon of choice: an iPhone.
“Being a social agent is really the coolest thing ever,” she said.
Kurtz is a content creator working through an app called Social Agent, part of an expanding gig economy where more and more workers are trading stability for flexibility. Work that once required connections, planning, and a big budget can now be booked with a tap —extending the on-demand model from rides and meals to storytelling itself.
Just make a request, and someone like Kurtz can arrive within 30 minutes, camera-ready.
“What I look for when I’m shooting events is very crisp and clean content,” she said.
Her mission this time took her to Sutro Nursery, a nonprofit dedicated to growing native plants and that is hoping to grow its volunteer base, too. Board member Maryann Rainey said booking a Social Agent is a lot cheaper than hiring someone to do their social media full-time.
“I know I can’t do it myself, and I was certainly hoping that these young people would know how to do a good film,” Rainey said.
A typical job runs about $200, with same-day delivery. Agents earn around $50 an hour, plus tips. And if clients already have footage, they can upload it and have it turned into a finished piece.
The service is currently available in New York, Los Angeles, and Miami, with a slower rollout now underway in other cities.
Lisa Jammal, the company’s CEO, said the idea is simple: Let someone else do the shooting.
“We all are missing those beautiful moments because we’re always behind the phone,” she said.
As for Kurtz, after the shoot, she headed straight to a nearby coffee shop, where the clock started ticking. She had just over an hour to shape her raw material into a polished final cut.
“I think I’m going to give this reel a really peaceful, calming feel, but also informative and inviting,” she said.

SF scientists build robotic storm samplers to track pollutants before they reach the Bay
SAN FRANCISCO (KGO) — Environmental Scientist Kayli Paterson from the San Francisco Estuary Institute is hitting the road with colleague David Peterson and a trunk full of water sampling robots.
“Yeah, I think the max we’ve ever done was five. But the sites are very close together. Oh, there it is. Hopefully it samples well,” says Paterson as she turns the mobile sampling lab onto a private oak-lined road.
They’re closing in on a watershed creek flowing through the hillsides near the San Andreas Lake reservoir, west of Highway 280 in Millbrae, part of the larger watershed that eventually drains into San Francisco Bay.
“So, we’ve got our sampler. Look at the battery. Hook that up, red and black. This is a 12-volt lithium battery, and it powers our sampler for probably about six to seven days,” she explains, showing off a self-contained unit miniaturized into a portable case.

The black cases are their latest innovation in stormwater science. Robotic samplers anchor in key sections of the watershed to monitor not only flow, but also the chemicals and pollutants washing downstream toward the Bay.
“And this is a front-line pollution sampler. It’s getting the stormwater before it enters the Bay. And so, we want to know what’s coming into the Bay and getting these samplers out there in more locations will give us a better idea of where we might have issues, where a hotspot is, or maybe a previously unknown contaminant,” says Paterson.
“It’s important to get out that fast,” her colleague David Peterson adds. “You know, in these storms as they’re happening, because the water is picking up pollutants in real time, and we need to be there to capture them.”
When we first met Peterson several years ago, he and another Estuary Institute team were sampling water along the Bay shoreline by hand, a technique that’s still valuable. But to cover more ground, Kayli and a group of collaborators began developing the robotic samplers over recent storm seasons.
Kayli and David start by chaining the unit itself to a tree near the creek bank. The system employs remote-controlled pumps that draw samples from the creek and store them in onboard containers. The software controlling the volume and frequency can be operated from a phone app.

One of the key targets in this study is a group of so-called “forever chemicals” known as PFAS, synthetic compounds that persist in the environment and have been detected in widespread areas of the Bay.
“And we capture samples and send them off to analytics labs across the country. Typically, universities or private labs will process these for us,” Peterson explains.
For these two stormwater detectives, it’s a mission that requires a combination of speed and patience**, chasing flowing water** through creeks and storm drains, sampling as they go.
“So, we’re looking for areas – the point of this is to do source control. Ultimately, we want to be able to trace this back to a possible source,” says Kayli Paterson.
And potentially prevent a source of toxic pollution from reaching San Francisco Bay and our Bay Area ecosystem.
More than a dozen of the robots were given names in a special contest, including the Big Sipper and the Tubeinator.

Floats for San Francisco Chinese New Year Parade get finishing touches
SAN FRANCISCO (KGO) — ABC7 Eyewitness News got a sneak peak as crews put the finishing touches on the floats you’ll see at Saturday’s San Francisco Chinese New Year Festival and Parade.
Since it’s the year of the fire horse, you’ll see a lot of horses and fire symbolism on the floats, housed at Pier 19.
“So Year of the Horse, it’s energy, it’s passion, it’s momentum so a lot of things that we’re really hoping to embody in the new year,” said Stephanie Mufson, owner of San Francisco-based The Parade Guys, which designs and constructs the floats.
She said they’ve been building them for about three months, with the designs starting in November.

“We’re in the home stretch,” she said. “We’ve got a couple of days left and we’ve got a nice little team that’s cranking out all the finishing work that needs to go into it.”
Derrick Shavers was sanding some wood that will be painted and become cherry blossom trees on a float.
“It’s exciting,” Shavers said. “I look forward to coming every year and just creating and making things shine and sparkle.”
Bon was painting mountains for a float, making sure everything is perfect in time for the parade.

“It’s one of the few parades that actually happens at night still,” Bon said. “So we got to make sure all the lighting is in check, and people are safe on the float. It’s all in the details, just for it to walk by you for 10 seconds.”
Ten seconds that bring so much joy to those watching the parade.
Here’s how you can watch the parade on ABC7 Eyewitness News on Saturday, March 7.
Coverage starts at 5 p.m. wherever you stream ABC7.
