摘要:

It would be difficult to overestimate the need for a physical understanding of natural phenomena in developing countries. Education, in modern times, goes hand in hand with empirical and mechanical interpretations of the physical world, in contrast with more primitive, animistic ideas. Quite apart from basic cultural drives, people in their daily lives see the need to explain and reduce the hazards caused by floods, droughts, earthquakes, tsunamis, volcanic eruptions, and land deformations, which continue to devastate wide areas of various parts of the world. In addition, there are the obvious applications of geophysics to exploration for mineral resources, to oil prospecting, and to the development of geothermal energy.

摘要:

The moons of Saturn, so Woody Allen recently observed [Allen, 1979], do not come up in conversation very often. This may be one reason why most people, planetary scientists included, have trouble pronouncing their names.Our troubles, however, stem not merely from the fact that these names are unfamiliar, or even that they are of non‐English origin. After all, the same is true of many terms in technology and medicine [cf.Nybakken, 1959;Reiche, 1959]. They stem from the fact that they are drawn from Greco‐Roman mythology and so possess the three chief difficulties troubling those who strive for ‘correct’ pronunciation anywhere in th

摘要:

The subject of the storage of nuclear wastes products incites emotional responses from the public, and thus the U.S. Subseabed Disposal Program will have to make a good case for waste storage beneath the ocean floor. The facts attendant, however, describe circumstances necessitating cool‐headed analysis to achieve a solution to the growing nuclear waste problem. Emotion aside, a good case indeed is being made for safe disposal beneath the ocean floor.The problems of nuclear waste storage are acute. A year ago, U.S. military weapons production had accumulated over seventy‐five million gallons of high‐level radioactive liquid waste; solid wastes, such as spent nuclear fuel rods from reactors, amounted to more than 12,000 tons. These wastes are corrosive and will release heat for 1000 years or more. The wastes will remain dangerously radioactive for a period of 10,000 years. There are advantages in storing the wastes on land, in special underground repositories, or on the surface. These include the accessibility to monitor the waste and the possibility of taking action should a container rupture occur, and thus the major efforts to determine suitable disposal at this time are focused on land‐based storage. New efforts, not to be confused with ocean dumping practices of the past, are demonstrating that waste containers isolated in the clays and sediments of the ocean floor may be superior (Environ. Sci. Tech., 16, 28A–

摘要:

Fundamental to understanding President Reagan's fiscal 1983 budget proposal, made public yesterday, and what the proposal means for the health of federally funded programs, is to comprehend the budget process itself. A table that outlines the budget process appears below; a short glossary (see box) defines some of the basic budget terms. Next week,Eoswill summarize the President's budget proposal. In 2 weeks,Eoswill analyze the budget proposal as it affects geophysicists.Congress, having just received the President's budget proposal, can begin to review it formally under the procedures mandated by the Congressional Budget Act of 1974 (see table). Note, however, that Congress often does not meet its budget deadlines.

摘要:

There were 2875 participants registered at the 1981 Fall Meeting and more than 1900 papers presented. The special session, Voyager 2 at Saturn, presented by E. C. Stone, drew close to 1600 people. It was the largest annual meeting AGU has ever held. Session chairmen's reports contained comments such as: AGU keep up the present momentum, … great session! The authors are to be commended, … all in all in a roar this was a super meeting, … the AGU Fall Meeting is still the best meeting going.If you missed it this year, plan now to go to San Francisco next Dec
