...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 hidden until the spring voyage of the Glomar Challenger...
...hope to learn much more about the mysterious undersea area by prowling the depths some 200 miles southwest of the Azores. Their goal: the exploration of a small section of the great volcanic rift valley that cleaves the Atlantic Ocean bottom almost all the way from the Arctic to Antarctica...
...ensure the survival of some species over long periods of drought and temperature extremes, nature has produced organisms that can exist many years in suspended animation. Last week two scientists announced that in soil samples taken from deep below the surface of Antarctica, they found frozen bacteria that may be anywhere from 10,000 to 1 million years old. When incubated, some of the bacteria not only returned to life but also reproduced...
Microbiologists Roy Cameron and Frank Morelli made their discovery by accident. The researchers, now at the Darwin Research Institute in Dana Point, Calif., had been working for the past three years on a project aimed at evaluating the environmental impact of deep drilling on Antarctica. As part of their work, they regularly analyzed the material brought up by the drills to determine what surface contaminants had seeped into the soil. Some experiments conducted on cores taken from layers of soil, rock and ice that had been laid down between 10,000 and 1 million years ago produced startling results. Several...
Died. Wolf V. Vishniac, 51, a microbiologist who designed one of the devices to be used to search for life on Mars during the U.S.'s first soft-landing attempt in 1975-76; after falling down an ice slope during an expedition to Antarctica. Vishniac's "Wolf trap" is the size of a cigar box and contains adhesive-coated strings that will be dragged through Mars' arid soil, then reeled into the container, where any life forms stuck to the strings will be detected. -Died. Marian Young Taylor, 65, known to radio listeners for 32 years...
