摘要:
While many in the oceanographic community enthusiastically look forward to the Ocean Margin Drilling (OMD) program, others are not sure that the science to be gained will be worth the commitment to such an expensive, technology‐intensive venture. The program was 7 years in the planning at the National Science Foundation (NSF), calls for a total cost of about $700 million over the next decade, and is to last through 1989.OMD was envisioned at the NSF as the next step after the enormously successfulGlomar ChallengerDeep‐Sea Drilling Project (DSDP). Now winding down, DSDP is scheduled to continue through 1981 and taper off in 1982. A proposal has been submitted that would extendChallengeroperations through 1

摘要:
On the basis of extensive radar data returned by NASA's Pioneer Venus spacecraft, scientists for the first time have mapped nearly the entire cloud‐shrouded planet and identified huge continent‐sized features—including mountains as high as Everest and deep rift valleys. Pioneer Venus has now mapped about 83% of the planet's surface and by month's end will have covered 93%. Prior to Pioneer, less than 1% of Venus' topography had been measured by ground‐based radar. Venus' surface has never been seen because of the clouds which permanently cover the

摘要:
The rapidly increasing number of requests from scientific and educational groups to inspect Mount St. Helens has prompted the U.S. Geological Survey staff at Vancouver to ask two Portland geologists to form a coordinating committee to screen all applicants.The committee is headed jointly by John E. Allen, professor emeritus of geology, Portland State University, and Ralph S. Mason, former state geologist with the Oregon Department of Geology and Mineral Industries Advisory members include representatives from Portland State University, University of Oregon, Oregon State University, University of Washington, the Washington Division of Geology and Earth Sciences, and the Oregon Department of Geology and Mineral Industries.
