...Columbia University and Peter Barker of the University of Birmingham led a multinational scientific team aboard the research ship Glomar Challenger this spring, probing the ocean depths east of the Falkland Islands. Lowering a coring drill 8,500 ft. to the bottom, they penetrated through 1,835 ft. of sediment before beginning to bite into the solid rock that they were looking for. Analysis of the core samples brought to the surface identified it as granite about 600 million years old. The find proved that the rock was continental shelf and not ocean basin crust, which is primarily basalt (solidified...
From examination of fossils in the sediment cores found just above the bedrock, the geologists deduced that 150 to 200 million years ago, the Falkland plateau was dry land in a climate similar to that of the Mediterranean today. That evidence fitted in with earlier suggestions by other geologists that there had once been an inland sea in Gondwanaland similar to the Mediterranean and bounded by what are now South America, Africa and Antarctica. Then, as the continents began to separate, the area round the ancient sea gradually sank, reached its present depth about 80 million years ago, and remained...
Last week the Glomar Challenger again made news. Another team of geologists announced that in July a drill lowered from the ship in midocean, about 200 miles southwest of the Azores, had penetrated 1,910 ft. into the earth's hard crust under the Atlantic bottom sediment. It returned core samples from depths never before explored; the previous record penetration was 260 ft. into the submarine crustal rock. Said Geochemist William Melson of the Smithsonian Institution: "It was like probing into the unknown, getting samples we had thought about for years but had never been able to reach...
...April on charges that he had provided $5,400 to student antigovernment agitators. Actually, his prosecution probably stemmed as much from his barbed poetry as from his relatively innocuous actions against Park. A typical portion of his Five Bandits describes ministers and vice ministers: "They waddle from obesity, and sediment seeps from every pore/ ... They command the national defense/ with their golf club in their left hand/ While fondling the breasts of their mistresses with their right...
Arcand also said flooding left layers of sediment on the steam tunnels' floors which will cost approximately $2000 to remove...
