The Cretaceous-Tertiary Event and Other Catastrophes in Earth History


Book Description

"This volume atempts to explore and clarify the relationship among the geological records, the extinctions, and the causes of catastrophes for life in Earth's history. Most of the papers address the geological record and the extinctions across the Cretaceou-Teriary boundary, and the buried Chicxulub structure that is now consensually deemed to be of impact origin and to be intimately related to that boundary."

Global Events and Event Stratigraphy in the Phanerozoic


Book Description

The existence of rapid and even catastrophic turnovers within the Phanerozoic ecosystems has been discussed controversially for more than 170 years. Since 1980 this discussion has become even more intensive after the hypothesis of Alvarez, explaining the end-Cretaceous mass extinction as the result of a huge asteroid impact on the Earth. This theory stimulated several thousand papers and is still controversial. The international research programme on "Global Biological Events in Earth History" attempts to bring the discussion back to the facts by using multidisciplinary investigations of the major Phanerozoic events. The results of an international group of experts are presented giving a wealth of information and a thorough discussion of the causes of the various global events.




Applications of Space Developments


Book Description

Applications of Space Developments covers the proceedings of the 31st Annual Congress of the International Astronautical Federation on Applications of Space Developments, held in Tokyo, Japan. The contributors consider the significant achievements and activities in Japan in the main areas of space applications, such as telecommunications, earth and ocean observation, materials sciences, and space processes. This book is organized into 22 chapters, which reflect the four main areas covered in the Annual Congress, including Earth-Oriented Applications of Space Technology, Earth Observations, Low-Gravity Environment, and Communication Satellites. The first chapters deal with the monitoring of earth and ocean energy resources, earth satellite power stations, energy conversion and transfer, structure technology, system fabrication and assembly of large space structures, and, nuclear waste disposal in space. The succeeding chapters are devoted to weather satellites, earth and ocean dynamics, earth and atmosphere pollution, payloads for earth and ocean observations, data analysis. These topics are followed by discussions on the theoretical and experimental aspects of microgravity materials, fluid and life sciences, the simulation of microgravity environment on earth, the effects of weightlessness on man, and the earth applications of space experiments. The concluding chapters survey the operational, experimental, and communication satellites systems, with emphasis on economic aspects and on the prospects of TV satellites. This book will prove useful to space scientists and technologists, astronomers, and satellite and communications engineers.
