摘要:
The period 1967–1987 saw a 20% increase in the time it takes to complete the doctorate. That figure is based on data provided by the National Research Council from 11 scientific and engineering fields, including the Earth, atmospheric and marine sciences.The median time spent earning the degree rose from 5.4 years in 1967 to 6.1 years in 1977 to 6.9 years in 1987—an increase of 1.5 years in a single generation. Completion time still seems to be rising! All graduating doctoral students in 1987 had a median age of 33.6 years; chemistry students were youngest at 29, and education students were the oldsters at 39.8 ye

摘要:
A number of different groups in Canada carry out research on the physics and chemistry of minerals. The majority of the research is conducted within universities, with the remainder occurring at government laboratories. Research groups span a wide range of disciplines, which include physics, chemistry, and materials science, as well as geology.Mineral physics research in Canada differs somewhat from the research that is carried out south of the border, and the difference can be attributed to several factors. With a population of one‐tenth that of its southern neighbor, Canada has significantly fewer scientists working on mineral physics problems. The smaller number of scientists combined with the vast area over which Canadian research institutions are distributed means that there are fewer scientists per institution that are working on mineral physics problems. The result is that many research groups focus not on mineral physics alone, but on problems such as magnetic properties of materials, with studies of minerals being but one component of the researc

摘要:
A good demonstration of voting power was provided at a March 13 markup hearing of the House Subcommittee on Space Science and Applications. After somewhat heated debate, the subcommittee voted generally along party lines to construct a new unmanned shuttle.Although the House and Senate have not agreed on final Fiscal Year 1990 NASA authorizing legislation, which both chambers passed last year, the subcommittee put its final touches on a new 3‐year NASA authorization bill. H.R. 4196 provides a 23% increase in budget authority, authorizing $3.4 billion in FY 1991, $11.2 billion in FY 1992, and $16.2 billion in FY 1993. Space interests have long sought a multiyear authorization, claiming it would ensure budget stabilit

摘要:
This monograph provides a regional view of global scale climate variability. Most of the chapters focus on the nature and causes of variability in the eastern North Pacific Ocean and western North and South America. Analyses of paleoclimatic, oceanographic, atmospheric, hydrospheric and terrestrial observations are presented. The volume has 23 chapters in 445 pages. This multidisciplinary effort grew out of the Pacific Climate Workshop (PACLIM), an annual gathering of diverse specialists to discuss topics associated with climate variability within that region.

摘要:
Scholars for the 1989–90 academic year. They are among the recipients of scholarships ranging from $500 to $2,000 under the American Geological Institute (AGI) Minority Participation Program. This designation recognizes AGU's continued strong support and substantial contributions to this program. Part of the support for this program comes from a matching grant from the National Oceanic and Atmospheric Administrations Sea Grant Program, which is aimed at increasing the number of minority students studying in fields related to the development of marine and coastal resource

摘要:
The Mineral Physics Committee is in its sixth year and my chairmanship will draw to an end at the AGU 1990 Spring Meeting. The Committee has agreed to recommend that Steve Kirby be appointed the next chairman. Steve, who is an experimentalist at the U.S. Geological Survey, Menlo Park, Calif., has contributed a great deal to our understanding of rock deformation and especially the role of phase transitions in the release of stored strain energy. He will be a very able leader who can strengthen our ties to sister disciplines.
