This book describes the Skylab 4 Earth Explorations Project. Photographs of the earth taken by the Skylab astronauts are reproduced here and accompanied by an analytical and explanatory text. Some of the geological and geographical topics covered are: (1) global tectonics - some geological analyses of observations and photographs from Skylab; (2)…

Geophysical activity increased in 1978, especially seismic gas and oil exploration in the United States and its waters. (BB)

Provides the theory behind the construction of a classroom seismograph. Data obtained from such a device is presented. (CP)

Describes a simple application of the seismic refraction method, using a two layer system, and extending it to a three layer system. (GA)

Discusses economic, social and political consequences of earthquake prediction. Reviews impact of prediction on China's recent (February, 1975) earthquake. Diagrams a chain of likely economic consequences from predicting an earthquake. (CS)

Discusses the destabilizing influences that affect feedback systems in the earth and trigger disorganization. Presents information that integrates mantle degassing with feed-back systems, and the Sun-Earth-Space energy flow system which is the primary source of energy that drives the Earth's biosphere. (RT)

Recounts the adventures of a journey taken through France and Italy. Makes an analogy of this trip to that of the one Charles Dickens took in 1844. Describes silicified horizons of the southern Paris Basin, moraines, outcrops, and "Hoodoos." (RT)

Performs an analysis of all 1128 publications produced by scientists during their employment at the University of Texas Institute for Geophysics, thus assessing research performance using as bibliometric indicators such statistics as publications per year, citations per paper, and cited half-lives. Evaluates five different methods for determining…

Selection and acquisition of relevant materials for building and developing an information infrastructure are modern worldwide problems. This document provides a core listing of journals in the earth sciences in an effort to develop a tool for the improvement of information handling and transfer. The core list was generated using several databases…

Reviews the earthquake phenomenon and its possible relation to ionospheric disturbances. Discusses the basic physical principles involved and the methods upon which instrumentation is being developed for possible use in a tsunami disaster warning system. (GA)

Described is the use of a microcomputer and computer software to simulate the use of geological equipment. The technique uses pictures of the control panel (with switches and dials that can be activated) and a story board that can provide the simulation. A simple seismograph is used as an example of possible simulations. (RH)

This high school-level classroom activity presents a hypothetical situation based on scientific fact concerning the likelihood that seabed mineral deposits lie off Easter Island. Activity goals, instructional strategies, and instructions for students are included. (JN)

Comments on the cooperative spirit of geophysicists which resulted in the largest scientific cooperative project ever conducted: the International Geophysical Year. Describes a new international venture (called Geodynamics Project) that is designed to exploit the many opportunities for new insights resulting from recent advances in earth science.…
