摘要:

It has been the custom to report the financial statement of the AGU to the council, and there has been little pressure to provide this information more generally. On the other hand the membership should be more aware of the way the union functions, and this report (see back of this page), prepared in my capacity as treasurer of the union, is intended as an educational feature.It will surprise no one to learn that more than 95% of the union's activity is involved with publishing. Our journals constitute 70% of this, the remainder being absorbed by Russian Translations and various monograph series. (The executive director's office has prepared a ‘Report on AGU Publications, Calendar Year 1974,’ which appears in the AGU section of this iss

摘要:

This review discusses the current knowledge of the gravity and geometry of the moon, and their implications as to lunar structure. Measurements pertaining to the gravity field are, first and foremost, Doppler tracking of spacecraft that have orbited the moon, but also the laser ranging from the earth to the moon and the gravity meters and accelerometers landed with the Apollo spacecraft. Measurements pertaining to the geometry include (1) those related to the shape: the metric photography and laser altimeters on Apollo 15, 16, and 17; the electromagnetic sounder on Apollo 17; the landmark tracking from earlier Apollo orbiters; and occupations, plus (2) measurements related to the orientation: the laser ranging and interferometry from the earth. The review does not cover determinations of topography from photography taken for geologic or landing reconnaissance purposes. The discussion of tectonic implications is limited to inferences of a quantitative nature. The emphasis is on work since 1970; seeKaula[1969, 1971] for reviews of earlier work.

摘要:

The Eight GEOP (Geodesy/Earth and Ocean Physics) Research Conference, on Lunar Dynamics and Selenodesy, was held October 10 and 11, 1974, at the Ohio State University. The conference, the last in the second year of the series, was attended by 66 persons.The meeting was opened by William M. Kaula, who also delivered the traditional introductory address, printed in its entirety elsewhere in this issue. The presentations and the discussions are summarized below by panel sessions.
