Blue Whale

Good for whales, bad for Labour

Apparently, some Labour sources tell me that there was a?lazy hundred grand offered to Labour prior to the election.

Tim Barnett failed to pick it up when Mike ‘Fat Tony’ Williams jacked it up doesn?t need to go on the whales.

With Labour getting?98% of their 2011 vote a spare hundy might have helped out.

Fat Tony apparently got?the shits with Tim for not turning up when the meeting was organised for the cheque collection and so the donor decided to give the money to saving the whales.

Which on the face of it looks like a more sensible investment.

The number of blue whales in the northeastern Pacific appears to have returned to near-historic levels thanks to a 48-year international ban on commercial or subsistence whaling for this species and allied laws enacted at national levels.

The current population of blue whales off the US West Coast is about 2,200, or 97 percent of their levels at the beginning of the 20th century, according to a study published Friday in the journal Marine Mammal Science. ? Read more »

Did Kim Dotcom die and wash ashore in Canada?

But I digress. Actually three rotting whale carcasses need disposing of and the Canadians are stuck in a bit of a conundrum as to how to get rid of them.

One man’s trash may be another man’s treasure, but a community leader says the hassle of dealing with rotting blue whales on Newfoundland’s west coast is a bigger problem than people may?realize.

Two blue whale carcasses washed ashore on the coast of Rocky Harbour and Trout River, both located near Gros Morne National Park. A sperm whale carcass also washed ashore in the Cape St. George area.

The animals died after getting caught in severe ice conditions off the island’s coast this winter.

Maurice Budgell, chair of the King’s Point Heritage Society, which operates the town’s Whale Pavilion, said when his community took on the task of getting the flesh off a humpback whale carcass, it was a bigger job than anyone bargained for, and they’re not interested in doing it again.

“With all of the problems that we had with the one that we have here now, it would be a monstrous job to take on something else like that,” said Budgell. ? Read more »

This won’t make me popular, but

MH370 or ...?

MH370 or …?

When I saw those satellite images, my first reaction was… what makes them think that isn’t a whale…? ?Did we really send all those people in to search for a juvenile blue whale?

The 52 hertz whale

This could is the whale song of what is possibly the world’s loneliest whale:

Since the 1980s, scientists have heard a single whale in the Pacific, singing at a higher frequency than any other?way up at 52 hertz, rather than down below human hearing at 15-20 hertz where blue and fin whales normally sing. In spite of listening in for two decades, no one has ever heard a lady whale reply. ? Read more »

What do Whales do when they dive?

Until now we have only had our imagination and some fleeting video to judge what Whales do when they dive.

A surfacing whale is a sight to see, but it would be even more dramatic to watch one ply the ocean depths. Researchers have taken a step closer to doing just that with sophisticated radio-tagging technology and a new computer program that uses the data to recreate a whale’s path underwater. The results, presented here yesterday at the annual meeting of the Society for Integrative and Comparative Biology, are helping scientists understand how the school bus-sized beasts are able to take in enough food to sustain their great girth, and how underwater noises, such as sonar, might affect their well-being.

Comparative physiologist Jeremy Goldbogen of the Cascadia Research Collective in Olympia, Washington, studies feeding in blue fin and other so-called rorqual whales. For almost a decade, he and his colleagues have been attaching suction cup radio tags onto the backs of the cetaceans. The tags record depth, sound, and other parameters as the whales swim. After a set amount of time, they fall off, float to the surface, and send out a radio signal so they can be retrieved and their data analyzed.

The work showed that in one giant gulp, a blue whale?the biggest creature on Earth?takes in 125% of its body weight in water and krill. During their dives, the cetaceans ram into patches of krill, opening their mouths wide and wrapping their jaws around prey-laden water, a move that stops them short. Next, they close their mouths and push water through their baleen, a system of plates that filter out the food, then speed up for another feeding bout.

There is a cool video that shows about 20 minutes of diving and feeding behaviour (compressed into a 30 second video):

…a tagged blue whale dives twice over the course of 19 minutes. The movie shows the whale moving at about 50 times its cruising speed. The first dive, to about 15 meters, takes about 2.5 minutes in real life; the second one, which includes feeding bouts, lasts more than 12 minutes and reaches down to 180 meters, where the whale lunges five times in quick succession, as if it were on a roller coaster.
