Maybe because we're heating the oceans to boiling point?

Marine scientists are trying to find out why previously unknown blooms of toxic algae are suddenly proliferating along the California coast, killing wildlife and increasing the risk of human sickness. The mysterious blooms have recently been bigger and have occurred more frequently than ever before, an alarming trend that a team of scientists led by UC Santa Cruz is attempting to figure out.

Scientists will also try to determine whether climate change is having an effect on the size, frequency and location of deadly algae blooms. "We can't say for sure that it is tied to something like climate change," Kudela said, "but it does seem to be spreading globally, so something is changing, and we are trying to find out what that is." Algal blooms are already known to be relatively common in the coastal waters of Oregon, Washington state and Canada. Recently, though, unusual toxic algal blooms have also been detected in the Gulf of Mexico, off the coast of Alabama, South Carolina, Florida, in Chesapeake Bay and the Gulf of Maine, according to researchers. Future outbreaks may be unstoppable, Kudela and others admit, but they hope the study will eventually help them develop a computer model that will predict blooms before they have a chance to cause havoc in the marine environment.

Killing the oceans

Bedraggled dead seabirds tangled in sea wrack on this remote, wild beach are just some of more than 8,000 birds killed since just after Labor Day, scientists estimate. The death toll — which might eventually pass 10,000 — is from a mysterious algae bloom still off the coast that has scientists and researchers worried and mystified.

"I think it's scary. We have no record of anything like this in the past 30 years, and no one knows why it is happening," said Julia Parrish, associate director of Aquatic and Fisheries Sciences at the University of Washington. "We are not used to big natural disasters, but this is one of them."

Up and down Washington's coast, scientists are reporting the longest lasting and largest harmful algae bloom ever recorded here, and the largest recorded mass mortality of seabirds ever in Washington waters. "It's bigger than an oil spill," Parrish said.

And in the Mediterranean:



And in Australia.

Don't forget Alaska's blob nor the Gulf of Mexico's dead zone, the plastic-filled gyres in the Pacific, the deep sea creatures and fish.

Global warming, rapid climate change... call it what you will. Our oceans are slowly boiling to death.

The Great Blob of Alaska?

It's not Putin's rearing head...

Palin's bloated ego....

or the oozing mass of ethics violations converging upon Wasilla....

Photobucket

but an unheard of algae bloom...

A group of hunters aboard a small boat out of the tiny Alaska village of Wainwright were the first to spot what would eventually be called "the blob." It was a dark, floating mass stretching for miles through the Chukchi Sea, a frigid and relatively shallow expanse of Arctic Ocean water between Alaska's northwest coast and the Russian Far East. The goo was fibrous, hairy. When it touched floating ice, it looked almost black.

But what was it? An oil slick? Some sort of immense, amorphous organism adrift in some of the planet's most remote waters? Maybe a worrisome sign of global climate change? Or was it something insidious and, perhaps, even carnivorous like the man-eating jello from the old Steve McQueen movie that inspired the Alaskan phenomenon's nickname? (Read Richard Corliss' review of The Thing, a sci-fi film set in the Arctic.)

The hunters got word to the U.S. Coast Guard, which immediately sent two spill response experts to fly over the mass, which looked sort of rusty from the air. They also approached it by boat. The North Slope Borough, the local government for the vast and sparsely populated cap of Alaska, sent its own people out the main village of Barrow to have a look. They scooped up jars of the stuff for analysis in a state lab in Anchorage.

"We responded as if it were an oil product," says Coast Guard Petty Officer Terry Hasenauer. "It was described to us as an oil-like substance, thick and lingering below the surface of the water. Those characteristics can indicate heavy, degraded oil, maybe crude oil, or possibly an intermediate fuel oil." Meanwhile, the story spread over the internet like an oil-spill, giving lots of people a queasy feeling. (Check out a story about the coming battle for the resources of the Arctic.)

Test results released Thursday showed the blob wasn't oil, but a plant - a massive bloom of algae. While that may seem less dangerous, a lot of people are still uneasy. It's something the mostly Inupiat Eskimo residents along Alaska's northern coast say they could never remember seeing before.
I think this is even scarier than Palin, Putin, and the Blob put together.... visions of our future, drowning in muck where our oceans used to be.
