摘要:

Recent observational and theoretical advances have provided new impetus for the study of the partly molten iron core of the earth. In 1983, the French Centre National de la Recherche Scientifique launched a multidisciplinary program to study the structure and evolution of the earth's core. This is an attempt to inform the scientific community of the aims and present status of the program and to summarize contributions to a state‐of‐the‐art meeting that was held in December 1985 in

摘要:

I am pleased to follow George Reid as president of the SPR Section. We owe George and his team a vote of thanks for leading one of the most active and productive sections in AGU. In the present piece, I will review the organization of the SPR Section for the coming 2‐year period and comment on the following topics: annual meetings, posters versus oral presentations, hard times, and new bloo

摘要:

A team of scientists presently working in Antarctica has announced some preliminary results of their studies of ozone depletion in the atmosphere over the south pole in the antarctic spring. Speaking via satellite at an October 20 press conference, the National Ozone Expedition (NOZE) said that their early measurements suggested that the antarctic ozone “hole” is not a result of upward wind motions or high solar activity, as some recent models have proposed. Although they have not established the cause, the group said, “we suspect a chemical process is fundamentally responsible for the formation of the hole.” Proponents of dynamical and solar cycle models, however, said that the data remain open to interpretation, at least until additional results are a

摘要:

It has become fashionable—even mandatory— in geophysical circles to think of Planet Earth as one interacting system and one that definitely includes the biosphere consisting of all living things. Of course, the founders of the American Geophysical Union must have subscribed in principle to that concept or they would not have created our multidisciplinary Union, but many universities still cling to those disciplinary pigeonholes. Old habits are hard to throw off, and it is often an extra effort to work at the interfaces between disciplines [Roederer, 1985].It has been the intense interest in the theory of climate, and the causes of climate change especially, that has spurred earth scientists to work more closely together during the past decade or more. It is clear that our climate models must take into account the atmosphere, the oceans, the cryosphere, the biosphere, the solid earth, and the sun (now recognized as a slightly variable star). It is this realization that has led to the move to organize a new international program, the International Geosphere/Biosphere Program (IGBP), sometimes referred to as “Global Change,” for short [Malone and Roederer

摘要:

AGU's second Richard Montgomery Field Fellow has begun his 10‐month tenure at AGU headquarters in Washington, D.C. William M. Sackett is a graduate research professor in marine science at the University of South Florida (St. Petersburg, Fla.).After just a few days at AGU, Sackett told Eos that he is now involved with helping to launch AGU's newest journal,Global Biogeochemical Cycles, and to organize sessions for the 1987 AGU Spring Meeting. Although it was too soon to say on which projects he will ultimately concentrate, Sackett said that he “would like to make some solid contributions to advancing AGU's goals.” He added that he is very much looking forward to getting to know the city of Washington during the coming
