As astute readers of my previous giant-squid posts will know, scientists have never observed one of these monsters alive. We only find them when they wash up dead on shores. In Spain, they normally only find one giant squid per year. But in the autumn of 2001, five suddenly washed up dead, and in 2003 another four were discovered. What happened to kill them all at once?
A marine expert in Spain thinks he knows the culprit: Oil companies. Angel Guerra of the Institute for Marine Investigations noticed that in those precise time periods, offshore oil companies were firing high-intensity sonar at the sea floor to try and find new oil reserves. Those sonar guns shoot utterly ferocious noise: 200-decibel pulses of 100-hertz sound, from an array of 10 guns. When scientists examined the dead giant squid, they found that none had external damage — so it was unlikely they’d been killed by another sea creature. But they did have extensive internal injuries, as the New Scientist reports:
In two squid the damage was extensive, with stomachs and hearts ripped open and muscles disintegrated. “Some organs were unrecognisable,” says Guerra.
And all the squid had badly damaged ears. Guerra thinks this might have disoriented the giant animals and made them swim to the surface, where they suffocated, as water temperatures there are too warm for the oxygen-carrying molecules in their blood to function. He suspects that in squid with massive internal damage, the blast caused dissolved gases in their tissues to form bubbles, such as those produced by shaking a fizzy drink.

From an interview with ethnobotanist and anthropologist Wade Davis:
One of the cultures you celebrate in Light at the Edge of the World is the Inuit. What do you most admire about them?
Davis: The Inuit didn’t fear the cold; they took advantage of it. During the 1950s the Canadian government forced the Inuit into settlements. A family from Arctic Bay told me this fantastic story of their grandfather who refused to go. The family, fearful for his life, took away all of his tools and all of his implements, thinking that would force him into the settlement. But instead, he just slipped out of an igloo on a cold Arctic night, pulled down his caribou and sealskin trousers, and defecated into his hand. As the feces began to freeze, he shaped it into the form of an implement. And when the blade started to take shape, he put a spray of saliva along the leading edge to sharpen it. That’s when what they call the “shit knife” took form. He used it to butcher a dog. Skinned the dog with it. Improvised a sled with the dog’s rib cage, and then, using the skin, he harnessed up an adjacent living dog. He put the shit knife in his belt and disappeared into the night.

“Video from a camp north of Toronto in December 2005 shows a car spinning around in a nearby, snow-covered parking lot. Prosecutors characterized that as special driver training but the defense, and many outsiders, said it was nothing more than “cutting doughnuts,” a favorite winter pastime of young Canadian motorists.” - A key piece of evidence submitted in the trial of a gang of alleged young Canadian terrorists.
