SEATTLE (AP) — U.S. scientists said Friday they will investigate why an unusual number of gray whales are washing up dead on West Coast beaches.About 70 whales have been found dead so far this year on the coasts of California, Oregon, Washington and Alaska, the most since 2000. About five more have been discovered on British Columbia beaches. That's a very small fraction of the total number of whales believed to have died, because most simply sink and others wash up in such remote areas they're not recorded.NOAA Fisheries on Friday declared the die-off an "unusual mortality event," providing additional resources to respond to the deaths and triggering the investigation."Many of the whales have been skinny and malnourished, and that suggests they may not have gotten enough to eat during their last feeding season in the Arctic," agency spokesman Michael Milstein told reporters during a conference call.The eastern North Pacific gray whales were removed from the endangered species list in 1994, after recovering from the whaling era.The population has grown significantly in the last decade and is now estimated at 27,000 — the highest since surveys began in 1967. That has raised questions about whether their population has reached the limit of what the environment can sustain. Another theory suggests that the loss of Arctic sea ice due to global warming is a culprit.The whales spend their summers feeding in the Arctic before migrating 10,000 miles (16,000 km) to winter off Mexico. Though they eat all along their route, they are typically thinning by the time they return north along the West Coast each spring.They eat many things, but especially amphipods, tiny shrimp-like creatures that live in sediment on the ocean floor in the Arctic. For many years, researchers noted that fewer calves tended to be born following years when the ice in the Chukchi Sea, north of the Bering Strait between Alaska and Russia, was late to melt. The whales had less time to feast because they couldn't access the feeding area, and thus had less blubber to sustain them on their next migration.Last year, though, the Artic was unusually warm. The whales weren't blocked from the feeding area, and yet are still struggling this year. That has scientists wondering if the loss of sea ice has led to a loss of algae that feed the amphipods. Surveys show the amphipod beds moving farther north, said Sue Moore, a biological oceanographer at the University of Washington."The sea ice has been changing very quickly over the last decade or so," she said. "The whales may have to shift to other prey, such as krill or other things they eat."In an average year, about 35 whales wash up in the U.S.In 2000, more than 100 did, prompting NOAA to declare an "unusual mortality event" then as well. The resulting investigation failed to identify a cause. The die-off followed strong changes in ocean conditions in the mid-1990s, suggesting that warmer water patterns affected the availability of prey, but scientists were often unable to perform necropsies, Moore said."It's sometimes very difficult to get to these whales in a timely fashion," she said. "You can't always get the kind of samples you would need for diagnostic reasons."Since then, researchers have built up an improved network of volunteers and have better educated the public to help report and respond to whale deaths, said Deborah Fauquier, veterinary medical officer at NOAA's Office of Protected Resources. This time around, scientists have been able to perform necropsies on 20 of the whales, she said.John Calambokidis, a research biologist with the Cascadia Research Collective, noted that as the whales search farther afield for food, they've entered areas where they're not normally seen so often, including San Francisco Bay and Puget Sound. That puts them at higher risk of being struck by ships or entangled in fishing gear.Four of the 10 gray whales found dead near San Francisco this year were struck by ships, and a number of shipping companies have slowed their vessels in the area to avoid collisions. 4086

SAN MARCOS, Calif. (KGTV) — A man was arrested after deputies say he fled the scene of a San Marcos crash and was stopped by passersby from leaving a second crash scene.San Diego Sheriff's deputies received a report of a beige Mercedes-Benz traveling at an unsafe speed on northbound Bennett Ave. before is ran off the road and collided with a concrete wall and then a residence at 600 Bennett Ave.The driver, a 26-year-old man, tried to flee the area, but was detained by passerbys until deputies arrived.While deputies were responding to that incident, SDSO says they received another call about a black, male suspect wearing camouflage clothing who had used a hatchet to smash the window of a vehicle at a Stater Brothers Grocery store at 1330 East Mission Rd. The man reportedly fled in a vehicle matching the description of the Mercedes-Benz and struck a gray Audi in the area of Knob Hill Rd., SDSO said. The driver of the Audi, a 61-year-old woman, was not injured. At the scene of the Bennett Ave. crash, paramedic treated the suspect at the scene and he was released. Based on evidence and interviews, deputies determined that the suspect was under the influence of prescription medication and heavily intoxicated at the time of the collision. The man was later arrested for driving under the influence, vandalism, and leaving the scene of an accident.SDSO's traffic division is investigating the crime. 1420

Secretary of State Rex Tillerson thanked agency staff in a message Friday, calling his service at the State Department "one of the great privileges of my life," just days after being fired by President Donald Trump in an early morning tweet."I depart my post with nothing but the best memories of working with my State Department colleagues," Tillerson said in the letter, the text of which was obtained by CNN and first reported by the Associated Press. "Know that I will continue to pray for our country, our leaders, and your efforts to make this world a better place than we found it. I am cheering for your success and thank you again for your service." 666

SANTA ANA (KGTV and CNS) - Authorities say five people were killed Sunday afternoon when a small plane crashed near a Santa Ana shopping center. The crash happened around 12:29 p.m. in the parking lot of the Staples Supercenter on the 3800 block of South Bristol Street. No one on the ground was hurt. As the plane barreled through the parking lot, it struck at least one unoccupied car, Orange County Fire Authority Capt. Steve Concialdi said. A nearby intersection was closed in all four directions near the crash. The parking lot is shared by Staples, a CVS drug store, a Michaels' decorations store, and a Wells Fargo Bank branch. The crash site is about one mile northwest of the northern end of the runway at John Wayne Orange County Airport. 781

SAN ONOFRE (CNS) - A man drove a stolen van onto the grounds of the now- idled San Onofre Nuclear Generating Station and claimed to have explosives in the vehicle, drawing a response from the San Diego County sheriff's bomb squad, which determined that there was no danger, authorities said Wednesday.The driver, 27-year-old Erik Jon Norman, was arrested on suspicion of felony vehicle theft, San Diego County sheriff's Sgt. Pamela Wotkyns said.Sheriff's deputies went to the nuclear station a little after 4:20 p.m. Tuesday after security officers reported that Norman drove a white delivery van past the entrance gate and into a restricted parking lot, Wotkyns said. The security guards quickly detained Norman, but he told them the van contained electronic equipment and "possible explosives."The sheriff's department's bomb/arson unit was called to the scene but determined the van contained no explosives, only standard shipping parcels, Wotkyns said. Deputies later discovered the van was reported stolen earlier in the day from Oceanside and arrested Norman, taking him to the Vista Detention Center where he remained in custody Wednesday in lieu of ,000 bail. 1178
