...Britain, a group of marine archaeologists has more to work with. When they located the 16th century warship Mary Rose (which sank in 45 ft. of water off Portsmouth in 1545) and raised it in 1982, half of the hull had been buried under protective silt for centuries. The waterlogged structure, part of which had the consistency of wet cardboard, was moved into dry dock at the Portsmouth Naval Base, and has since been sprayed constantly with a cold-water mist to keep the wood from disintegrating in the air. This treatment will continue for another three years, after which...
...tour of the Titanic, running videotapes shot by the Argo as it was dragged by the Knorr back and forth in a series of passes over the site. The dramatic tapes clearly show the great ship sitting upright, pointing toward the north and covered with a fine layer of silt. The port and starboard anchor chains are wrapped around their capstans, still holding the anchors in place, and in the top deck there is a gaping hole that was once a skylight. Through it, Ballard told his viewers, "you can see right down the grand staircase." The railings and wooden...
...pioneer's spirit, but Rich McIntyre was literally in the wilderness when he found his calling. Fly-fishing on the banks of Montana's Gallatin River in 1977, McIntyre, then a 23-year-old landscaper, noticed brown trout thrashing about in a muddy stream bed nearby, trying to clear silt from the bottom so they could lay eggs on clean gravel. Deciding to help the fish reproduce and make some money for himself, he became America's first commercial stream doctor...
...fees of up to $50,000 a mile, McIntyre has worked with wealthy landowners, anglers and developers to rehabilitate streams that became barren of trout, whose eggs die if covered with silt. His firm, Timberline Reclamations, based in Bozeman, Mont., has worked on 130 projects in 17 states and has attracted a small school of competitors with names like InterFluve and Stream Team...
...Ocean's equivalents of the hurricanes of the Atlantic and the typhoons of the Pacific, have boiled out of the moist, hot air over the Bay of Bengal to sweep across Bangladesh. With its wide-open flatlands and labyrinthine waterways sprinkled with hundreds of chars (tiny islands created by silt deposits from the rivers and tributaries that empty into the bay and shift as the water level changes), southern Bangladesh is especially vulnerable to the attacks of great tropical tempests. Seven of the world's ten most destructive killer storms on record have ripped through the Bay of Bengal...
