Since 1981, the use of personal computers (PCs) to increase productivity has become widespread. At present, more than 5 million personal computers are in operation for business, education, engineering, and scientific purposes. Activities within AGU reflect this trend: KOSMOS, the AGU electronic network, was introduced this year, and the AGU Committee on Personal Computers, chaired by W.H K. Lee (U.S. Geological Survey, Menlo Park, Calif.), was recently formed. In addition, in conjunction with the 1986 AGU Fall Meeting, this committee is organizing a personal computer session and hands‐on demonstrations to promote applications of personal computers in geophysic

摘要:

Greek concepts of winds in the earth as the cause of earthquakes persisted until the latter part of the 19th century. The proportion of earthquakes believed to be caused by volcanic processes has progressively decreased. During the 19th century, faulting gradually emerged as the principal cause, becoming firmly established as a result of studies of the 1891 Mino‐Owari and 1906 San Francisco earthquakes. With improvements in instrumentation, details of the mechanics of faulting became revealed by measurements of seismograms. It is now sometimes possible to estimate fault displacement, moment, the dimensions of displaced blocks, the velocity of rupture, and the location of the initiation of faulting from seismogram

摘要:

The middle atmosphere (stratosphere, mesosphere, and lower thermosphere) is now being studied intensively. Mesosphere‐stratosphere‐troposphere (MST) radars are playing a vital role in observing middle atmospheric motions. These radars receive very weak echoes caused by scattering from atmospheric density fluctuations that are produced by clear air turbulence. These irregularities move with the local wind so that the Doppler shift of the radar echo power spectrum gives the component of the local wind along the line of sight of the radar b

摘要:

The American Institute of Physics (AIP) has announced the appointment of a new chief executive officer, Kenneth W. Ford, who is to succeed H. William Koch when Koch retires on March 28, 1987. Koch has held the position since 1966.AIP is a not‐for‐profit scientific organization made up of 10 member societies, including AGU, that represent more than 90,000 scientists. Its main activities include scientific publishing and marketing of 76 primary physics journals, including translations of foreign journals, books, conference proceedings, and the magazinePhysics Today. AIP also is involved with electronic abstracting and other scientific communications and has active programs in education, public information, manpower statistics, and the history of phys

摘要:

The STIP (Study of Travelling Interplanetary Phenomena) Project of the Scientific Committee for Solar‐Terrestrial Physics held its fifth international meeting in Les Diablerets, Switzerland, June 10–12, 1985. The STIP Project has as its objective the interdisciplinary, informal, and internationally cooperative study of specific solar and interplanetary events during all parts of the solar cycle. The purpose of this meeting was to bring together scientists from all areas of solar‐terrestrial physics, both theoretical and experimental, to promote this coordinated study of coupling between the sun and the heliosphere and, in particular, to focus attention on 14 specific intervals of study and to outline scientific objectives for five future intervals. The meeting consisted of six successive sessions and an open business meeting. The program was arranged so that previously appointed coordinators could present invited half‐hour summaries of the scientific highlights that characterized each of their Intervals. Contributed papers of 20‐minute duration were interspersed among the chronological Interval presentations with 10–20 minute informal discussions following the speakers' presentations. There were 42 scientific papers presented at the meeting by 45 participants from 13 countries. The cosponsors of the conference, along with the Scientific Committee on Solar‐Terrestrial Physics, were Committee for Space Research, International Astronomical Union, and International Union of Pure and Applied Physics. The papers presented at the Les Diablerets meeting will appear inSTIP Symposium on Retrospective Analyses(M. A. Shea and D. F. Smart, Editors), a publication by the STIP Project, which is to be available

摘要:

The AGU Geomagnetism and Paleomagnetism (GP) Section has announced its selection of a paper entitled “Multicomponent Magnetization of the Upper Silurian‐Lower Devonian Ringerike Sandstone, Adjacent Dikes, and Permian Lavas, Oslo, Norway” as the best GP student paper presented at the 1986 AGU Spring Meeting. The primary author, Dartmouth College Ph.D. candidate David Douglass, was assisted on the paper by a colleague from Lamont‐Doherty Geological Observatory. Douglass received his B.S. in geology from the University of California, Los Angeles, in 1980, and in 1984, he received his M.S. in earth sciences at Dartmouth. His current studies examine the paleomagnetism, structure, and sedimentation of several North Atlantic old red sandstone
