摘要:
A Mars mission, a new research thrust on the continental lithosphere, increased efforts in digital cartography, and construction of a Very Long Baseline Array radio telescope top the list of highlights for geophysics‐related research in the proposed fiscal 1985 federal budget that President Ronald Reagan sent to Congress earlier this month.Science in general fared well in this fourth Reagan budget. Research and development support would grow 14% to $53 billion ($51.8 billion would go to conduct of R&D, while $1.3 billion would be allocated to R&D facilities). With a projected inflation rate of about 4%, this increase would provide real growth of 10% over fiscal 1984 levels. The largest increase for R&D, 22%, would support defense modernization. Figure 1 compares nondefense federal R&D obligations since 1978 in constant 1983 dollars, while Table 1 compares conduct of R&D by major departments and agencie

摘要:
In his State of the Union address on January 25, President Ronald Reagan announced that he was directing the National Aeronautics and Space Administration (NASA) to “develop a permanently manned space station, and to do it within a decade.”Included in the NASA budget proposal sent to Congress the following week was $150 million for the station. This is the first request of many; expected costs will total roughly $8 billion by the early 199

摘要:
A new radio‐telescope observatory located at Richmond, Fla. (near Miami), made its first successful Very Long Baseline Interferometry (VLBI) observations on December 9, 1983, according to the National Geodetic Survey (NGS). This test session was followed on December 21 by the first operational observing session of the full, three‐station POLARIS (Polar Motion Analysis by Radio Interferometric Surveying) network (the Richmond facility plus observatories near Boston, Mass., and El Paso, Tex.).The POLARIS network was joined in the historic, December 21 observing session by VLBI observatories in Onsala, Sweden, and Wettzell, Federal Republic of Germany. Only 8 hours of operations yielded sufficient data to determine the location of the Richmond site relative to the other four North American and European observatories to within a fraction of a meter. Refinements will quickly reduce uncertainties to a few centimet

摘要:
There are quite a large number of excellent publications now available in the domain of carbon dioxide and climate. After a period of intense research on the subject conducted under the sponsorship of national and international institutions like the U.S. National Research Council, the U.S. Department of Energy, the Environment Agency of the Federal Republic of Germany, the Scientific Committee on Problems of the Environment, the International Institute for Applied Systems Analysis, the World Climate Program, the Commission of the European Communities and others, syntheses are now possible.Over the past decades, extreme climatic events in different parts of the world have made us aware of our vulnerability to climatic variations and variability. But it is also more and more recognized that not only man may possibly be affected by climate but also that climate is vulnerable to man's activities. These human activities, especially those related to industrial processes and the practice of agricultural burning and soil management, result in the release of particles and trace gases in the atmosphere. The increase of atmospheric CO2which is worldwide poses a special problem of major concern.

摘要:
This interesting, albeit uneven, little book reviews a broad range of topics related to the collection and analysis of seismic reflection data. In spite of its misleading title, it deals less with the geological interpretation of reflection sections than with the geometrical analysis of seismic raypaths. For example, statics corrections and migration theory—topics or peripheral interest if not indifference to most interpreters—are subjects of entire chapters while seismic stratigraphy, one of the hottest current branches on interpretaion, is not even mentio

摘要:
In only 5 days the AGU 1983 Fall Meeting in San Francisco accommodated more than 3100 attendees and more than 2100 papers. Each of the special, all‐Union sessions attracted crowds of close to 1100 persons. Except for the 1982 Fall Meeting, which covered 8 days and included the American Society of Limnology and Oceanography (ASLO) Winter Meeting, 1983's was the largest AGU Fall Meeting ever.The large number of presentaions at the 1983 meeting was handled efficiently by assigning more than 30% of the papers to poster sessions, which were to many participants the highlight of the meeting. Poster presentations are becoming extremely good, and some of the more spirited sessions make many oral presentations seem pale in comparison. The sight of some of the world's leading geophysicists chatting over a poster paper with a student attested to one of the advantages of this type of presentatio

摘要:
The all‐Union session on the Geophysical and Geochemical Consequences of Nuclear Explosions at the 1983 AGU Fall Meeting attracted a large audience, and many were unable to find a seat or standing room. The speakers and questioners emphasized the complexity of the processes and the need to extend the computer models. In particular, the global‐circulation models presented byscientists from the National Center for Atmospheric Research showed that smoke/dust clouds should cause major changes in the weather systems with great contrast between the temperature perturbations over oceanic, coastal, and continental regions. Important developments in the models and conclusions can be expected over the next few years as AGU members from many disciplines contribute their ski
