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

SANTEE, Calif. (KGTV) – Two teenaged girls had a frightening encounter with a stranger the parking lot Sportsplex USA Santee Thursday night.“He’s lucky I didn't walk out to minutes earlier,” Beau Branton said. His 14-year-old daughter was one of the girls involved.Branton plays in an adult softball league. Their game finished around 11 p.m. His daughter and her 13-year-old friend were there. After the game, they went to the pickup truck to get warm, while Branton finished up on the field.That’s when a man came over to the teens sitting in the car.“They saw him coming over and when they saw him coming over, they freaked out and locked it," Branton said. "He started yanking on the handle to get in.  When he realized he couldn't get in, he just stood there and didn't say anything, just a blank stare.”After a few seconds, the man seemed to give up and leave.“(My daughter) got out to come get me,” Branton said. “She came out from the truck, and towards the Sportsplex, that’s when (the stranger) came from behind a car and started chasing her.”His daughter got back into the truck in time to watch the man drive away.“He had a hoodie on, backpack,” he said, “cleanly shaven, he had two shaven notches on his eyebrows.  They watched him get into a red minivan and drive away.”San Diego Sheriff's Department said the suspect is described as a Hispanic man in his early 30s, about 5-feet 9-inches tall, and weighing about 170 pounds. He reportedly has short brown hair.He also had two shaved lines through his right eyebrow.The suspect reportedly fled in an early 2000's model, dark, red minivan with faded paint and a sticker on the back window.Deputies are working with the girls to create a sketch of the suspect and are asking any other witnesses to come forward.Lt. Chris Steffen says they are not yet sure of the man's intentions and that he might not have known the girls were in the car. But he says they take every case involving juveniles and strangers seriously.Anyone with information is asked to call SDSO at 858-565-5200.  2095

SAN FRANCISCO (AP) -- The fearsome NFL pass rusher Fred Dean has died. The death of the former San Francisco 49ers star on Wednesday night was confirmed by the Pro Football Hall of Fame.Ex-teammate Dwight Hicks says Dean was hospitalized last week with the coronavirus and was on a ventilator. Dean was 68 years old.Dean was a key part of the launch of the 49ers' dynasty. He was an undersized pass rusher who began his career as a second-round pick with the San Diego Chargers in 1975 and ended it in the Pro Football Hall of Fame after being named an All-Pro twice and making four Pro Bowls.Dean was an All-Pro for the Chargers in 1980 but had his biggest impact after being traded to San Francisco during the 1981 season.Dean is a member of the Chargers Hall of Fame and was named to the Bolts' 40th and 50th anniversary teams. 838

Security experts are clarifying what you should know about the hack against the U.S.Last week, federal authorities warned of the breach in government and private computer systems. It's suspected that Russian attackers were behind it.Some members of Congress have voiced concerns that taxpayers' information could be exposed through the treasury department. But one expert tells us that isn't really valuable to these attackers.“The breach over the last week is much more geared towards nation state secrets, manufacturing secrets, supply chain secrets, you know different intellectual property, than it is personal information,” said Randy Watkins, Chief Technology Officer at CriticalStart.Watkins says the average person likely won't see any immediate impact, but with policy information and military strategies at risk, there could be downstream ramifications.Federal authorities say the hackers primarily got in through software called solar winds that some agencies use.Watkins says that means we need to look more at how we measure security for third party vendors.“A lot of times, the attackers don't need to go directly after the treasury department or the department of defense. Those are very locked down networks, but they can go after the third parties that do business and have connections into those environments, and that's what they did in this scenario.”Officials say this hack could have started as early as last March.Watkins says the type of tech they used is hard to catch, allowing attackers time to patiently collect data under the radar.That means working on detection methods will also be key moving forward. 1641

SAN YSIDRO, Calif. (KGTV) - The first eight migrants in a caravan of hundreds will be processed, a source confirmed Monday night. Women and children were the first to be selected out of the group. Earlier Monday, 20 families were waiting to be processed at the San Ysidro port of entry. Customs officers say the border crossing facility is at capacity. Those crossing the border say the caravan is fenced off in two sections. One group of about 20 is at the door, waiting to be processed.Irineo Mujica of Pueblos Sin Fronteras, the group organizing the caravan, called the refusal to process the asylum seekers a 'farce'.MAP: Where is the migrant caravan from?Some 50 Central American immigrants camped on a sidewalk near the San Ysidro Port of Entry Sunday night. They're part of a group of hundreds who intend to enter the U.S.The caravan faces a challenge when, and if, they reach this country. They must have proof of their need for asylum in the United States.Customs and Border Protection says it will resume processing when it has more space and resources. 1101
