The waters near the nation's largest port complex have become a bustling feeding ground for increasing numbers of blue whales, putting the endangered animals at greater risk of being hit and killed by the enormous ships moving in and out of the harbor, according to researchers who've been tracking them for nearly two years.
The whales, which migrate along the coast of California and are regularly spotted from May to December, are congregating in such numbers in the midst of this virtual freeway of ship traffic that the spot has become "the area of densest concentration close to shore in all of California," said research scientist John Calambokidis. Daily appearances by the world's largest animal feeding along an underwater drop-off outside Los Angeles Harbor have been a huge draw for sightseers. But the underwater buffet of krill, the shrimp-like crustaceans the whales feast on, is in the path of a major shipping lane and puts them in danger of being hit and killed by vessels leaving the port.
"While this is a unique and exciting opportunity to have these animals out here, it also puts them at great risk," said Calambokidis, co-founder of the Olympia, Wash.-based Cascadia Research Collective. Over the last decade, dozens of whales off the California coast have been injured or killed by ships, and scientists think the slowly recovering population of about 2,500 West Coast blue whales is especially vulnerable.
Four blue whales were struck and killed by vessels in 2007 near the Channel Islands National Marine Sanctuary off the coast of Santa Barbara, raising the alarm of federal wildlife officials, who now monitor the whales from the air and use their coordinates to issue notices asking freighters to voluntarily slow down. With the increase in blue whales near the Los Angeles-Long Beach port complex, Calambokidis said, "now we're worried about here."
