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 YSIDRO, Calif. (KGTV) -- Firefighters were able to knock down a two acre brush fire in San Ysidro Sunday morning. According to San Diego Fire Rescue, the fire sparked just before 7:20 a.m. in a rural canyon east of San Ysidro. The department says, due to the difficult terrain, crews had to be flown in to fight the blaze.

The cause of the blaze is unknown at this time, but the Metro Arson Strike Team has been called in to investigate. 569

SANTEE, Calif. (KGTV) - Extra law enforcement officers are in place at Santana and West Hills High Schools in Santee due to unsubstantiated threats of violence.The Grossmont Union High School District and both schools’ administrators were notified Monday of the emailed threat that referred to a possible act of violence, according to a district spokesperson.San Diego County Sheriff’s investigators are looking into the matter.RELATED: San Diego Unified, San Diego Police outline school safetyThe district issued a statement which read in part: 553

SAN YSIDRO, Calif. (KGTV) - Border officials highlighted their accomplishments Friday, saying the past year has hit some benchmarks."The past year has taken a tremendous toll on our agency, our agents and their families," Kathleen Scudder, Acting Chief Patrol Agent for the San Diego Sector said, referring to the thousands of migrants who traveled to the U.S.-Mexico Border in San Diego County.While a nearly 14-mile stretch of new bollard fencing was completed in August, from the beach to Otay Mountain, officials said their agents faced more attacks compared to the previous fiscal year."There were a total of 156 assaults on agents while performing their duties, agents endured 72 assaults the prior fiscal year," Scudder said.While arrests at the border have been down the last six months, drug smuggling has shifted to the water, Scudder said. Agents seized 3,273 pounds of marijuana, 1,284 pounds of cocaine, 3,918 pounds of methamphetamine, 288 pounds of heroin and 108 pounds of fentanyl "that could provide a fatal dose to 24 million people."Customs and Border Protection Agents shifted their role over the past year, providing much needed humanitarian aid for migrants from caravans. While agents faced national scrutiny for their treatment of migrants, Scudder described a show of kindness."Our agents persevered, often bringing items from their homes to care for small children and babies in their custody," she said.She described an act of heroism where an agent found two boys who were lost near Chula Vista. He found one of the boys unconscious, suffering from hypothermia. He wrapped the boy in his coat and hugged him, to provide body warmth until help arrived. The boy recovered and went home six weeks later.Scudder said she expects the downward trend in illegal border crossings to continue, thanks to the wall, agreements with agencies and Mexico, and Migrant Protection Protocol in place. Border officials said migrants in custody for more than 72 hours are often held past the mandated time due to medical or processing complications. 2067

San Ysidro, CA (KGTV)- The border wait times to cross into the United States are significantly shorter Tuesday.According to a U.S. Customs and Border Protection App, the wait times at the border in San Ysidro averaged around an hour depending on the time of day.In the last few days, border crossers reported waiting up to ten hours to cross into the U.S."A lot of people going to the border five, six hours before their work entry, it's been crazy," said Jose Montanez.Montanez is a married father of two. He lives in Tijuana, but crosses to work as a manager at a taco factory. He said the lines this weekend were especially bad, even in the pedestrian lanes."Four hours, five hours waiting in line, standing in line, you get tired," said Montanez.Last Friday, CBP began "adjusting operations" to focus on essential travel. The goal is to slow the spread of COVID-19.A spokesman with CBP sent 10News a statement, that reads in part:"According to the U.S. Customs and Border Protection, a recent survey of more than 100,000 travelers on the southwest border found that the vast majority of cross-border travel by U.S. citizens and lawful permanent residents is for purposes that are not deemed essential. To respond to the ongoing public health crisis and protect local southwest border communities, CBP is taking measures to discourage non-essential travel to and from Mexico to limit the spread of COVID-19 in the United States. "Fewer lanes and increased secondary inspections led to massive delays."If they have to ask more questions and isolate people from one another so the essential workers can go and cross faster, that would be perfect," said Montanez.Instead, innocent workers are feeling the impact the most."Those that are crossing right now are doing so cause they really need to and they're going to continue crossing," said Paola Avila, of the San Diego Regional Chamber of Commerce.Restrictions have been in place at the border since March. Avila said the new protocol now doesn't make sense, especially since San Diego County is off the state's COVID-19 monitoring list."Non-essential businesses are going to start reopening. More businesses are going to start reopening, so you're going to have a greater workforce that's going to have to facilitate those businesses reopening, but now you're going to have these restrictions. It's not in sync with the rest of our procedures and regulations and restrictions," said Avila.She worries the strategy could backfire and lead to more virus spread, especially for people using the pedestrian walkway."Now, you have large masses of people with no social distancing, you're creating an unsafe environment," said Avila.Montanez says he does his best to keep his distance while in line."You do, even though, you're close to each other, there's no space between the front and the back of you," said Montanez.Agency officials urge people to only travel to Mexico if it's necessary."We need people to think twice about non-essential travel and to ask themselves if the travel is worth risking their lives and the lives of others. Mexico continues to experience spikes in positive COVID-19 cases along the Southwest border and it is our duty to do everything we can to protect our nation, including educating citizens and even discouraging non-essential travel to Mexico." 3336
