Before 1980 the Gaussian cgs (cm‐gm‐s) system of units provided the standard for magnetism in the area of geophysics. Although the cgs system was not without its own special and formidable set of problems, geophysicists had come to terms with it to the extent that the published literature contains little ambiguity about the meaning of a magnetic measurement expressed in cgs units. At about that time, following recommendations of various international committees, some journals began suggesting, and then requiring, that SI (Systeme Internationale) units be used instead. There are significant advantages to SI units, and it behooves us to accept the conversion and make it work. Most of the geophysical community has already done

摘要:

A joint report issued January 8, 1986, by special envoys from the United States and Canada recommends that the United States implement a 5‐year, $5‐billion commercial demonstration program for technologies to control emissions from the burning of coal. The recommendations call for government and industry to share the costs of the proposed program.The report was issued by Drew Lewis, former U.S. Secretary of Transportation, and William Davis, former Premier of Ontario, at the request of U.S. President Ronald Reagan and Canadian Prime Minister Brian Mulroney after a summit conference between the two leaders in March 1985. Discussion of the report is on the agenda for a second meeting this coming March. Reagan has said he will review the report but has not committed himself to endorse its recommendati

摘要:

This book is a milestone in our understanding of the origin of life on earth and its subsequent early development. Its editor, J. E. Schopf, assembled an interdisciplinary team of 24 experts, the Precambrian Paleobiology Research Group (PPRG), who worked together for 14 months. Their official report, the volume reviewed here, has the following stated goals: first, to report the original research results obtained by the PPRG; second, to provide an in‐depth summary of relevant data; third, to provide an integrated assessment of current evidence on the early history of life; and fourth, to highlight unsolved problems. T h e book succeeds admirably in achieving these goal

摘要:

This book focuses on a man who, in his lifetime, was scarcely known to the general public. Yet within certain circles, Richardson has had enormous impact within recent years. Although there are many scientists and humanists who exercise influence in their own respective fields, rarely do they bridge disciplines. It is this combination that has made Lewis Fry Richardson a figure worthy of a full‐length biography, not just to record his contributions to each field but to provide an analysis and understanding of what motivated his diversity. In another age, Richardson would have been counted as a Renaissance man. He has variously been referred to as a chemist, physicist, mathematician, psychologist, meteorologist, economist, and biologist. In retrospect, he clearly was well ahead of his time, whether the subject in question was his work in numerical weather prediction or in war studie

摘要:

Kenneth O. Emery is the consummate scientist in his chosen field; inventive, curious, imaginative, a leader, a listener, a teacher, an iconoclast, and the inveterate producer, all carried out with ingenuity and a warm, humorous yet constant personality. He is the friend one always appreciates, who is ready with counsel for every idea, who can think through nearly any question, big or small, and provide the logical brackets in which your concept is comfortably enclosed. For all of us, he stands high as the exemplary marine geologist of our time.

摘要:

Stan Gianzero, whose photograph appears below, has been cited for excellence in refereeing. His photograph was not available at the time that other AGU journal referees were cited (Eos, September 3, 1985, p. 635). The time and diligence contributed by AGU's reviewers enhances the quality of the Union's journals. The editor's citation recognizes this special service to AGU; Gianzero, along with his fellow referees, is to be commended for consistently providing constructive and thoughtful reviews.

摘要:

A U.S.‐Japan Seminar on recent advances in the understanding of structures and dynamics of the heliomagnetosphere, formally entitled “Recent Advances in the Understanding of Structure and Dynamics of the Heliomagnetosphere During the Current Maximum and Declining Phase of Solar Activity,” was held on November 5–9 , 1984, in Kyoto, Japan. There were 46 papers presented in seven sessions. Among this total, 22 papers can be classified as observational and analysis papers, 18 may be considered theory and modeling papers, and 6 were papers dealing with programing methods. A total of 60 scientists attended this seminar: 19 from the United States, one from the Netherlands, one from India, and the rest from Japan. In addition, three graduate students were in attendance. This account of the seminar, which was sponsored by the National Science Foundation and Japan Society for the Promotion of Science, will be organized according to four topical categories: large‐scale structures, mass ejection and heliospheric dynamics, particle acceleration and cosmic rays, and solar radio
