Describes the theory behind the workings of the Hubble Space Telescope, the spherical aberration in the primary mirror that caused a reduction in image quality, and the corrective device that compensated for the error. (JRH)

Estimates of undiscovered oil resources are developed in two general ways: historical-trend analysis and geological analogy. Each of these methods is discussed. Indicates that only well-defined and repeatable methods project a rather bleak future for United States oil discovery. (JN)

Plate tectonics is the current framework for understanding earth history and processes. Recent progress in this field is discussed, focusing on continental growth, mountain building, hot spots, and mineral depositions. (JN)

Discusses the challenges confronting plate tectonics. Presents evidence that contradicts continental drift, seafloor spreading, and subduction. Reviews problems posed by vertical tectonic movements. (Contains 242 references.) (DDR)

Reviews current ideas and research findings related to the flow patterns of mantle rocks. Highlights the components of the two-layer convection and whole-mantle models of mantle flow. Proposes that mantle flow is the key to understanding how the earth has cooled and chemically evolved. (ML)

In preparation for the Voyager flybys in 1989, the pace of ground-based investigations of the moons of Uranus, Neptune, and Pluto has quickened considerably. Information derived from these investigations is presented. (JN)

Seismic events which took place during 1982 form the focus of this review on 1982 seismic research activities and projects. Funding problems for local and other networks, earthquake-prediction research (funded by National Earthquake Hazards Reduction Act of 1977: P.L. 95-124), use of computers, and aftershocks are among the areas addressed. (JN)

New seismic techniques have been developed recently that borrow theory from academic institutions and technology from industry, allowing scientists to explore deeper into the earth with much greater precision than possible with older seismic methods. Several of these methods are discussed, including the seismic reflection common-depth-point…

The controversy surrounding the potential storage of nuclear waste at Yucca Mountain, Nevada, is discussed. Arguments about the stability of the site and the groundwater situation are summarized. The role of the U.S. Department of Energy and other political considerations are described. (CW)

Lists causes of freshwater supply depletion and successful reclamation projects including Imperial Dam in California, desalination in Arizona, and dual water supply in Florida. A national water policy is advocated. (DH)

The Landsat Program became the major event of 1982 in geological remote sensing with the successful launch of Landsat 4. Other 1982 remote sensing accomplishments, research, publications, (including a set of Landsat worldwide reference system index maps), and conferences are highlighted. (JN)

Described are lecture topics and laboratory assignments for a course offered to engineering technology students specializing in construction. A dual-purpose laboratory which serves both engineering technology students and civil engineering students is described. The course work may be presented during either a 10-week quarter or may be expanded…

Presents excerpts from "The Comet Book," a nontechnical primer on comets. Various topics discusses in these excerpts include such basic information about comets as their components, paths, and origins. (DH)

In August, 1981, National Aeronautics and Space Administration launched Dynamics Explorer 1 into polar orbit equipped with three cameras built to view the Northern Lights. The cameras can photograph aurora borealis' faint light without being blinded by the earth's bright dayside. Photographs taken by the satellite are provided. (JN)

Three major breakthroughs in Antarctic earth sciences which occurred during 1982 are discussed (finding of land fossils, meteorite, and subsurface microorganisms). Highlights of conferences, research activities, and significant publications are also discussed. (JN)
