The Brief

It's not a surprise, there may be sharks sharing the ocean with you. But don’t worry, there are ways to enjoy the water and stay smart out there.

Cal State Long Beach is inviting the public to its Shark Lab on Saturday. The lab studies shark behavior — mainly in the waters from Monterey Bay to San Diego — and works to demystify perceptions of great white sharks, one of the most common in SoCal waters.

Saturday’s open house between 10 a.m. and 3 p.m. will provide the public with tours of the facilities and an opportunity to see these awesome creatures live.

“Our main mission is really to study the behavior and ecology of sharks and [there] physiology,” said Chris Lowe, professor of marine biology and director of the Shark Lab at Cal State Long Beach. “But the other part of our mission is really to get that scientific information out to the public.”

What the lab does

The lab studies all types of sharks, game fish and stingrays. It also helps the state to determine big marine protected areas for various species.

With the growth of the white shark population, the lab received state funding in 2018 to develop a shark beach safety program.

“We were working with all the ocean lifeguards who were going, ‘OK, where are all these white sharks coming from that are hanging out on our beaches? How long are they going to be here? When are they going to leave and do they pose a risk to the public?'” said Lowe.

Movies like the Steven Spielberg classic Jaws have driven negative perception of sharks, portraying them as ferocious beasts that will eat humans. Unprovoked white shark attacks on humans in California are rare. Lowe said on average there are 3 attacks each year, the majority of which are attributed to white sharks.

“If you’re going to the beach and you’re worried about sharks, learn what species are there. It's not like Jaws out there and it’s not like Discovery Channel Shark Week,” Lowe said.

The lab has tagged about 240 sharks, and tracks them using underwater sensors and buoys. Currently, the lab maps the location of sharks, and Lowe said in the future, the hope is that they'll be able to share that data in close to a real-time basis with the public.

How changing climate impacts sharks

In the last decade, one thing the lab noticed was that warming ocean temperatures have driven shark breeding and feeding to the north, in addition to other marine life that the lab studies.

Prior to 2015, there had been no breeding areas for the white shark in Monterey Bay, according to Lowe. But since the implementation of the Clean Water Act and other federal climate legislation in the early 1970s, California’s water has been getting increasingly cleaner and populations of whales, fish, seals and sharks have significantly rebounded, and in turn, Lowe says that this has improved both the habitats and the number of prey for sharks.

Beach safety this summer

If you do encounter a shark at the beach this summer and if the shark is acting aggressive, Lowe recommends giving it a “bop” on the nose, so the shark knows you will fight back. If it's just close in proximity, keep your eyes on the shark and move your surfboard toward it and it will often just swim away.

“We really don’t know why sharks occasionally bite people unprovoked, the provoked bites are really easy to explain, you know, a fisherman or somebody grabs a shark, gets too close and the animal feels threatened, so they’ll bite,” Lowe said.

Cleanup is just beginning for a contaminated industrial site in South Gate, according to U.S. Environmental Protection Agency officials who are leading the effort.

The small southeast L.A. city was built on industry — in the early 20th century it boomed with auto, chemical and other manufacturers.

That legacy also left it with three Superfund sites, areas designated by the federal government as highly contaminated with hazardous waste.

The three sites are all clustered on a large lot framed by Southern and Rayo avenues. A residential neighborhood is nearby.

“This site is less than 50 yards away from a home, so we want to make sure that we clean it to a point where we can feel confident,” said South Gate Mayor Joshua Barron.

South Gate is home to about 90,000 people, the majority of whom are Latino. The median household income is about $74,500 and the state has identified the city and surrounding communities to be disproportionately burdened by pollution and its health effects.

This site, dubbed the Southern Avenue Industrial Area, housed a screw manufacturing business for 30 years, then a carpet adhesive plant. Both businesses are now defunct and the site was designated by the federal government as a Superfund site in 2012.

The pollution at this property was compounded by pollution from companies next door.

One of the two adjacent Superfund sites was used by Cooper Drum Co., a steel drum recycling plant. A group of Cooper Drum’s former customers, including chemical manufacturers and oil companies, are paying for part of that cleanup. The other site, previously operated by an aircraft rivet and conveyor belt manufacturer, is still in the analysis and planning stages.

At the Southern Avenue site where the EPA broke ground Tuesday, analyses commissioned by the agency found widespread lead and other toxic contamination in the soil, as well as a plume of trichloroethylene, a carcinogen, in the groundwater.

Officials say the plume has not affected the deeper aquifer South Gate and other southeast L.A. cities rely on for drinking water.

In 1986, the city closed water wells contaminated by the neighboring Cooper Drum site.

“ The water is safe to drink,” said Mike Montgomery, superfund director for the EPA. “What we're trying to do is prevent it from becoming impacted.”

EPA officials estimate soil cleanup will take about two months. Groundwater cleanup planning will start in 2027 and could take a year or more. The whole effort is estimated to cost between $45 million and $60 million, primarily through federal dollars.

The summer heat may be sweltering at the moment in Southern California, but predictions about this winter’s El Niño show it could be the strongest on record.

So the LAist newsroom wants to know: What questions do you have? (You can submit below.)

We can tell you now that El Niño is a climate pattern that happens roughly every two to seven years, and is one of the most powerful drivers of the Earth’s weather.

During an El Niño event, the central and eastern tropical Pacific Ocean off the coast of South America warms to above normal temperatures. The warm ocean adds moisture and heat to the atmosphere, influencing atmospheric circulation, temperatures and precipitation on a massive scale.

El Niño typically results in mild weather in the northern United States and wetter conditions in the southern part of the country.

In Southern California, we could start to see the effects of El Niño in the late fall or early winter. Generally, those effects include significant rain and high sea levels and the consequences that come with them, such as flooding, mudslides and coastal erosion.

Forecasters say there is a more than 90% chance of a powerful El Niño event this year, and a 70% chance that it’s record-setting.

That said, uncertainty remains around how exactly this winter’s El Niño will play out here.

So as you gear up for an El Niño winter, ask us your questions and we’ll do our best to get answers in the months ahead.

The company behind the Garden Grove hazardous waste scare earlier this year is planning to resume full operations in late September, subject to an independently monitored, court-approved safety plan.

GKN Aerospace employs 500 people at its Garden Grove facility.

What happened?

GKN Aerospace said in a news release that it had permanently decommissioned the tank that set off the hazmat scare in May and forced some 50,000 nearby residents to evacuate.

Removal of the tank is pending review and approval from state regulatory agencies, according to an emailed response from Salma Elshakre, a spokesperson for the Orange County Health Care Agency, which is overseeing the cleanup.

All of the toxic chemical, methyl methacrylate (also known as MMA), has been removed from nearby tanks as well, Elshakre said.

What about the compensation fund?

This week, the company also announced a forthcoming $100 million compensation fund for affected residents and businesses. GKN expects to release details on how to apply in the coming months.

What's next?

At least 39 lawsuits have been filed against the company in conjunction with the hazmat incident, according to a GKN webpage set up to track the fallout. The company pledged to explain the legal effect of participating in the compensation fund before it is launched.

What's the community reaction?

Garden Grove Mayor Stephanie Klopfenstein said in a statement that the city “welcome[s] this progress and will continue to expect GKN to address the broader effects on our community.”

A coalition of community groups called GKN Out of Garden Grove Coalition wants the city to shut down the GKN plant completely. The coalition plans to release a report documenting the company’s alleged history of hazardous waste failures at a news conference Tuesday at 5:30 p.m. at 11300 Stanford Ave. in Garden Grove.

WASHINGTON (AP) — The Trump administration is preparing to revoke the business and tourism visas of up to 200,000 foreigners who have applied for or are currently seeking asylum status in the United States. If it happens, the move would be the largest single mass revocation of visas in U.S. history and would likely face legal challenges.

Unless challenged or revised, the State Department is expected to announce in the coming weeks the revocation of so-called B1 and B2 visas issued between 2016 and 2026 whose holders have sought asylum or are now seeking asylum, according to State Department documents obtained by The Associated Press and two U.S. officials. The action will be taken in coordination with the Department of Homeland Security.

“We are coordinating with DHS to identify and revoke the nonimmigrant visas of foreigners who have come to the United States claiming to be short-term visitors, but then file for asylum to stay here permanently,” said State Department spokesman Tommy Pigott.

He declined to comment on the number of visas that might be revoked, saying “as the process will be ongoing, the number of revocations remains dynamic and will be done on a rolling basis.”

The revocations would not necessarily result in their immediate deportation, the officials said. Most of those with asylum cases currently pending would be recategorized but would lose their status as business or tourism travelers, according to the officials, who spoke on condition of anonymity because the revocations are not final yet.

Since President Donald Trump took office for his second term last year, his administration has steadily ramped up restrictions on visa applicants — demanding more information about their social media histories, requiring the posting of expensive bonds for the processing of visas, and outright banning the issuance of visas to citizens of certain countries.

In a social media post on Monday, Deputy Secretary of State Christopher Landau called out people who he said try to use tourist and business visas to get into the United States and then apply for asylum.

“People in the US and all over the world are fed up with bogus asylum claims,” Landau wrote on X. “Asylum isn’t supposed to be a loophole to circumvent immigration law.” Landau cited the case of a Colombian citizen who came to the U.S. in 2015 on a tourist visa and then applied for asylum.

B1 visas are generally issued for business trips and B2 visas are generally issued for tourism, family visits or medical care. It was not immediately clear from the documents or the officials how many of these visa holders are seeking or have sought asylum in the United States and would be affected by the revocations.

Current applicants for B1 and B2 visas are asked to affirm that they will not apply for asylum in the United States and prove that they intend to return to their home countries.

In the past 18 months, the State Department has revoked about 175,000 visas for people who have been convicted or accused of crimes ranging from drunken driving to rape and robbery, as well as for people who have spoken out publicly against U.S. policies, particularly in the Middle East.

The administration has also moved to crack down on so-called birth tourism, a practice the administration claims is used by foreign pregnant women to come to the United States to give birth so that their child will benefit from birthright citizenship. Trump has tried several times to end birthright citizenship, but those challenges have been rejected by courts, including the Supreme Court.

The State Department documents obtained by the AP suggest screening of current B1 and B2 visa holders began after the State Department received information about asylum requests from the U.S. Citizenship and Immigration Services.
