摘要:

As president of the Section of Solar‐Planetary Relationships of the American Geophysical Union I agreed last year, in cooperation with the American Meteorological Society, to sanction, in the name of our union, a scientific review of the Climatic Impact Assessment Program draft monographs 1, 3, and 4. I not only suggested names of referees but, upon request, participated in the process myself.The ‘Executive Summary of the Report of Findings’ by the DOT in my opinion conceals the logical conclusions of the CIAP study as it was presented in the monographs we saw and criticized: it introduces new concepts concerning ultimate SST fleet sizes, flight times, and emission standards without candidly stating the ultimate effect of such fleets by the early twenty‐first century on the stratosphere; and it, together with uncorrected stories based on it and press interviews accompanying its release, have caused serious loss of credibility to atmospheric sci

摘要:

It has been nearly eighteen years since the initiation of the ‘spaceage’—an age characterized by the exploration and utilization of space by satellites. Satellite explorations now have ranged from within the orbit of Mercury to well beyond the orbit of Jupiter. The attractiveness of explorations to the outer reaches of the solar system, coupled with a depressed budgetary situation, may jeopardize smaller, yet productive, programs studying the near‐earth environment. I recognize the difficult and often thankless task of program managers in funding agencies to make hard decisions concerning various research and exploration program pri

摘要:

Thirty years ago, when we began to use rockets to explore the upper atmosphere, there were all kinds of questions that needed an answer. Before that time the study of the ionosphere, the aurora, and other high‐altitude phenomena was wholly indirect, that is, by deduction from what was observed from the ground. But this led to endless discussions of what atoms and molecules are there, what are the winds and other motions, what reactions do solar radiations cause, what happens in an aurora, how is the ionosphere formed, and what changes take place between day and night, between the different seasons, and throughout the sunspot cycle. The arguments went on and on and led to few firm conclusions because of lack of the on‐the‐spot measurements needed to choose between the many theoretical possibilities. The sounding rocket (Figure 1) and later the satellite and the space probe changed all that, and they have had a remarkable and salutary impact on a number of scientific disciplines. This influence is well illustrated by both the earth sciences and astr

摘要:

An Interdisciplinary science seminar on the antarctic Dry Valley Drilling Project (DVDP) of Japan, New Zealand, and the United States (McGinnis et al., 1972) was hosted by the Quaternary Research Center, University of Washington, in Seattle, May 29 to 31, 1974. The seminar was held to provide a forum for scientists, adminstrators, and support personnel to report on achievements of the project to date and to finalize drill sites for 1974–1975.The seminar is one of many supported through the U.S./Japan Cooperative Science Program. It was jointly sponsored by the Japan Society for the Promotion of Science and the U.S. National Science Foundation. The area involved in DVDP studies is shown in Figure

摘要:

We recently spent three and a half weeks in the Soviet Union as part of the Soviet/American Working Group on earthquake prediction. We visited the seismological field station at Garm as well as several institutes in Moscow, Tashkent, and Dushanbe. We examined and discussed at some length some of the ongoing experimental research pertaining to earthquake mechanics and prediction. In the following note we mention the laboratories and individuals currently engaged in experimental work, for the benefit of our American colleagues who may wish to communicate with their Soviet counterparts.

摘要:

A major deep seismic sounding experiment is being carried out in the British Isles as a cooperative effort of groups in Germany (Geophysikalisches Institut der Universitaet Karlsruhe) and the United Kingdom (I.G.S. Seismology Unit, Edinburgh, and the Department of Geology with Geophysics, University of Birmingham.)Now known simply as LISPB (Lithospheric Seismic Profile in Britain), the project was first proposed during the 1972 European Seismological Commission (ESC) meeting in Brasov as a result of discussions of recent French, German, and Swiss seismic studies—in particular, the 1000‐km Brest‐Toulon profile (seeZeitschrift Fuer Geophysik, vol. 39, p. 363, 1973). A seven‐member working group was formed from the three participating institutions. This group has since met several times—for example, during the 1973 meeting in Zurich of the European Geophysical Society (EGS)—to organize the experiment. Minor parts of the program were completed during August and December 1973; the main program was carried out in July and

摘要:

Following publication of the report U.S. Program for the Geodynamics Project: Scope and Obectives by the U.S. Geodynamics Committee (USGC), ten ad hoc reporters were designated to develop recommendations concerning implementation of the topics in the chapter ‘Intitial Priorities.’ The societies that have been actively interested in the Geodynamics Project were informed of this action and were invited to nominate people to work with the reporters for the various topics.The Geodynamics Project correspondents in geoscience departments (about 140) were urged to inform their colleagues; all were encouraged to communicate directly with the reporters, who took initiative in communicating with those known to be interested in their particular topics. All of them held at least one meet

摘要:

The Geological Society of America has announced plans for a Conference on Regional Geophysics and Tectonics of the Intermountain West to be held September 7 to 12, 1975, in Alta, Utah.The purpose of the meeting is to examine Cenozoic tectonics and interpretations of regional geophysical data of the intermountain west in light of the general theory of plate tectonics. Emphasis will be placed on the transition zone from the Basin and Range province to the Colorado Plateau and the middle Rocky Mountains provinces, the eastern Snake River plain, and Yellowstone National Park.

摘要:

Two international water resources meetings will be held at Colorado State University in Fort Collins from June 27 to July 2, 1977.The Third International Symposium in Hydrology with the theme 'Theoretical Hydrology' will meet June 27 to 29, 1977. The following five topics will be discussed: (1) relations between hydrologic processes and spatial and temporal distributions of energy; (2) change in the characteristics of hydrologic processes as water moves through various earth environments; (3) analysis of relationships between water quality and water quantity; (4) physical justification of structural models of hydrologic processes; and (5) prediction and detection of long‐range hydrologic change
