摘要:

A spacecraft hurtles through the cosmos. For a brief period the craft has been manned, but the travelers have no control over its course, speed, or destination. During the endless flight, they depend on the supplies already on board or those that can be produced there. To endure the voyage, their house must be kept in order.For awhile the travelers were few, supplies seemed unlimited, and there were numerous corners into which the refuse could be swept. But the crew increased in number more and more rapidly. Distribution of supplies became unsatisfactory, and the suspicion arose that the quantity might be inadequate. In a sense, the craft seemed to be getting smaller. Even the corners were filling up.

摘要:

The ferment of the times is penetrating all sectors of our society. Scientific organizations are beginning to feel the impact. Many scientists feel that their voices should be heard in the political arena. This is a legitimate claim. But some also feel that the scientific societies should become involved. This requires a very close look.

摘要:

There has long existed a need for pelagic tide and current measurements, but the technology for making such observations has been developed only recently. In 1965, an international working group on deep‐sea tides was formed (now sponsored by IAPSO, SCOR, and Unesco) that would concern itself with the exchange of information on instrumentation and analysis and with the formulation of a worldwide data acquisition program.Some pelagic tide observations have now been obtained by pressure sensors on the sea bottom connected by cable to the surface [Eyri`es, 1968] or to shore [Nowroozi et al., 1968] and by self‐contained bottom instruments that record internally and are recalled to the surface by an acoustic signal [Snodgrass, 1968] and time‐release device [Filloux, 1968, andHicks et al., 1965]. The equipment described by Snodgrass and by Nowroozi include current meters measuring speed and direction. The over‐all objectives of the deep‐sea tide program are described byMunk and Zetler[1967] andCartwri

摘要:

Plans for U.S. participation in the Global Atmospheric Research Program (GARP), as developed by the U.S. Committee for GARP, and related scientific, technological, and organizational factors will be presented and discussed by members of the GARP Committee and by invited speakers. The meeting is planned mainly to inform atmospheric scientists about plans for GARP, especially those researchers interested in participating in various aspects of GARP. Sponsors include the AGU, the American Meteorological Society, and the University Corporation for Atmospheric Research in Cooperation with the National Academy of Sciences. The National Center for Atmospheric Research in Boulder will serve as host. Richard J. Reed, National Academy of Sciences, is Program Chairman.

摘要:

The Institute of Geophysics at the University of Mexico has announced several new programs. The University will offer the first graduate degree in geophysics available in Latin America, including a strong emphasis on applied mathematics, seismology, and exploration geophysics. A study of earthquake risk estimation using Bayesian statistics and derivation of terrain factors for magnitude‐intensity relations is now in progress, and will be eventually incorporated into a map of seismic regionalization of Mexic
