摘要:

In our age of technological revolution, wisdom requires that a reasonable balance of scientific opportunity be given to science across the whole range of scientific inquiry. Doubtless, at any moment, great advances in knowledge and applications of that knowledge can be acquired by great emphasis on some very significant area of science. Certainly the emphasis on the fundamental constitution of matter with the consequent development of nuclear energy has led man to extrordinary new capabilities in his control over nature and its consequent opportunities for higher civilization.In the face of this mighty advance in knowledge, man's failure to press his science in other, perhaps less spectacular, directions leaves him without adequate means to harness and control this new knowledge.

摘要:

Before an agreement to suspend nuclear weapons tests can be reached the problem of detecting violations must be resolved. Seismology offers the only means for detecting the occurrenceof an underground nuclear explosion.In the summer of 1958 the Geneva Conference of Experts made the first attempt to gage the detection capability of seismic methods. Although the work of the Conference was hampered by a lack of experimental data, certain conclusions were reached estimating the level of an underground nuclear explosion which would be susceptible to seismic monitoring by a specified network of stations. Subsequent to the Geneva Conference, additional experimental data became available as a result of the Hardtack II test series which was conducted in the fall of 1958. It is in the nature of scientific inquiry to review earlier conclusions in the light of new data. The new results thus stimulated a reevaluation of the Geneva recommendations.

摘要:

Forecasting the nature, thickness, and movement of sea ice is a major problem in naval operations in polar areas. This problem faces the under‐ice submarine as well as surface ships. In fact, the sea‐ice forecasting problem has expanded from concern only with the marginal borders of the ice pack to need for information on the character of the whole frozen surface of the Arctic Ocean known as the Permanent Ice Pack. The variation in the thickness and size of individual floes, their movement and especially the zones of convergence and divergence are significant. These factors determine where the ice is likely to be unusually thick and where open leads or thin ice may be formed. Under‐ice navigation also requires information on the nature of the ocean floor, the circulation of the ocean water, its temperature, salinity, and acoustic characteri

摘要:

This book on the description and theory of the Gulf Stream necessarily discusses aspects of the circulation of the entire Atlantic Ocean, which has features common to the Pacific and Indian Oceans; in effect, a large part of modern physical oceanography is covered. The first six chapters, on basic principles of oceanography and on history and descriptive features of the Gulf Stream, can be read without any special training. The remaining six chapters, on modern theoretical studies, involve physical and mathematical concepts of varying difficulty. “The purpose of this book is to describe and explain what is known about the Gulf Stream in a way which will interest physical scientists.” I think the book will be of great interest to all oceanographers and has parts that will appeal to anyone wanting information about the Gulf Stream. The illustrations alone form a valuable and unique collect
