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

Sears desperately needs money to keep it afloat during bankruptcy. And now the deadline is getting tighter.The retailer, which filed for bankruptcy on Oct. 15, has already gotten a 0 million loan to help fund its operations while it tries to reorganize. It warned the day it filed that it would need an additional 0 million loan within weeks or else its ability to stay in business would be "seriously jeopardized."But now Sears has postponed a hearing that was set for November 1 to win bankruptcy court approval of such a loan, according to a court document filed Wednesday. No new meeting date was set.Sears declined to comment on the delay.A hedge fund owned by Eddie Lampert, who is also Sears chairman and majority shareholder, was expected to lead financing of the 0 million loan.CNBC reported Thursday that Lampert is looking to ensure that his hedge fund would get paid back first when it comes time for Sears to reimburse its creditors. Specifically, Lampert wants his ESL Investments hedge fund to have the same status as major banks like Wells Fargo and Citigroup that provided the initial 0 million loan, CNBC reported.Meanwhile, Sears is bleeding money. It said it is burning through cash at a rate of 5 million a month, according to its first-day filings.The 132-year-old company has been struggling for several years and is already drowning in debt. It was forced to file for bankruptcy when it came time to make a 4 million debt payment but didn't have the cash.Lampert, who gave up the CEO role at Sears as part of the filing, has been loaning money to Sears for years. But he has always taken steps to ensure that his loans are backed by hard assets, such as real estate or credit card balances, to improve his chances of having the loan repaid even in the case of bankruptcy. Even if Sears liquidates, he'll end up holding real estate worth hundreds of millions of dollars.Lampert is the company's largest creditor. He's owed at least .6 billion. 2024

SAN MARCOS, Calif. (KGTV) — San Marcos is taking a stricter stance on pet control.A newly passed ordinance allows the city to label people “irresponsible pet owners” and levy harder penalties.The city or the San Diego County Humane Society can impound the animals of people who are declared “irresponsible owners” under the ordinance and ban hem from owning any animals for up to three years.According to the rules, an “irresponsible owner” is an individual who has received three of more citations in the last two years for an unrestrained animal, guard dog, dangerous animal or nuisance violation.Dangerous animals per the ordinance are those that have attacked a person or another domestic animal two times within four years, or have injured or killed a person once within four years. 795

SANTA ANA, Calif. (AP) — Orange County’s new interim health officer says he will lift a requirement that residents wear face coverings in public and instead recommend they do so to help reduce the spread of the coronavirus. The change comes three days after the previous health officer abruptly resigned following threats she received over her order requiring masks as the county allowed more businesses to reopen. Residents have railed against the requirement at public meetings. Los Angeles and San Diego counties have similar requirements. The head of the Orange County Medical Association says using a mask is a small sacrifice to protect others. 658

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
