Gray whale off Israel called 'most amazing sighting in history of whales'

By: Pete Thomas, GrindTV.com

The discovery Saturday of a gray whale swimming in the Mediterranean Sea off Israel has been labeled by Robert Brownell, a prominent cetacean researcher, "the most amazing sighting in the history of whales."

Alisa Schulman-Janiger, who runs a gray whale census and behavior project in Southern California for the American Cetacean Society, said the sighting was "the equivalent "of finding a dinosaur in your backyard--it was that unbelievable."

To be sure, scientists are perplexed as to how the gray whale might have traveled from the Pacific to the North Atlantic--the most likely entry point to the Mediterranean--where the species is believed to have been extinct for about 300 years.

Among questions being asked is whether--if other gray whales also have gained or will in the coming years gain access to the Atlantic--this could mark the beginning of a re-population effort by a species not encountered in the region since the late 17th or early 18th centuries.

Brownell, who works for the National Oceanic and Atmospheric Administration, believes it could if the consensus among scientists is accurate that a diminished ice cover in recent years in the Arctic region, where the eastern North Pacific stock of gray whales feeds during the summer, has provided pathways to the Atlantic.

"We've had other strange sightings, like narwhals from the U.K. or Japan, but those are still within the same ocean basin that they're known to occur in," Brownell said of Saturday's sighting. "So they're unusual but not as unusual as something showing where it had once gone extinct."

The 40-foot whale was spotted more than a mile beyond Israel's Herzliya Marina, close to Tel Aviv, and followed and photographed for two hours by scientists from the Israel Marine Mammal Research & Assistance Center. They initially assumed it was a sperm whale because, like gray whales, it lacked a dorsal fin. But the mammal was later positively identified as a gray whale.

While the news has not yet been widely reported, it has generated a buzz of excitement among scientists and conservation groups.

Erich Hoyt of the Whale and Dolphin Conservation Society blogged on Monday: "Discounting the possibility of the Panama or Suez canals, I suggest that the Northwest Passage is the most likely entry route. In August, 2007, it was announced that the Northwest Passage was nearly ice-free for the first time and these conditions continued into the summer of 2008."

To be sure, gray whales could not have survived in the North Atlantic unnoticed for 300 years, so it's universally agreed that this particular whale hails from the eastern North Pacific stock--the only viable population of gray whales, numbering about 19,000 animals.

These whales are renowned travelers; they feed during the summer in the Bering and Chukchi seas, and migrate each winter more than 5,000 miles to mating and calving grounds off Baja California, Mexico.

To reach the Atlantic by means other than an Arctic route, they'd have to either swim through the Panama Canal or continue another 8,000 miles to the south and round Cape Horn at the bottom of South America.

Scientists have discounted both possibilities. That leaves the Arctic route, either an easterly Northwest Passage journey across the top of North America, or a much longer westerly voyage across the top of Russia.

Brownell agrees the former journey represents the most likely scenario and adds that gray whales in the Atlantic might have historically come from the Pacific stock.

Historically there were three distinct populations of gray whales--the eastern North Pacific stock; the North Atlantic stock, and the Korean or western Pacific stock.

The western Pacific stock is critically endangered and might number fewer than 100 animals.

The North Atlantic population probably became extinct in large part because of hunting during the whaling era. Fossil records have shown that gray whales utilized both sides of the Atlantic. They probably shared a common northern feeding ground and fossils have been found as far south as Florida.

It is not known what the whale was doing in the Mediterranean, when it entered the Atlantic or whether it was the only gray whale to have strayed into that ocean. But from now on, scientists will be on the look out for more of the same species.

Officials have stopped guessing at the amount of oil leaking although some speculate it may be closer to 1 million gallons per day.

Don't let BP spin this into something trivial.

"It's not a leak, it's a volcano spewing oil"


On May 7, environmentalist John Wathen of Alabama went out with a pilot friend to see the Deepwater Horizon mess for himself. Wathen, who lives in Tuscaloosa and works as the Hurricane Creekkeeper, tells us he's never seen anything like it in two decades of activism:
This is the first time in my environmental career that I've ever used the word "hopeless." But it's hopeless. You cannot stop it. This is going to hit all our shores. And it's not a question of if it goes into the Gulf Stream. It's when.
