摘要

One day in november 2000, the trawler Ocean Selector took a fateful detour in its search for groundfish. Captain Brian Dickens had charted a course to a location south of Vancouver Island, British Columbia. He strayed beyond the fishing grounds inhabited by his competitors to try someplace new. Trawling an undersea valley called Barkley Canyon, he dragged his net at a depth of 500 fathoms (3,000 feet), almost twice the depth anyone else usually went. He had hoped to find a bonanza of perch and rougheye. What the ship netted that day instead would be the single biggest haul on record of a substance like something out of Jules Verne's 20,000 Leagues Under the Sea and known only to those familiar with the deep ocean. Selector's net snapped off a chunk of mysterious ice from the seafloor. The mass strained the trawl net's 150,000-pound capacity. However, by the time it came to the surface, it weighed only 15,000 pounds. The block was the size of a school bus. Dickens recalls that when he first saw it bobbing on the water, it looked like a yellowed piece of iceberg but behaved like an Alka Seltzer, well on its way to seething into nothingness. His perplexed crew hauled the chunk into the fish hold. By this time it weighed only two tons.
