Research in Antarctica is becoming increasingly important in studies of connections within the Earth's geosphere-biosphere system. Upper atmosphere research explores Sun-Earth interactions, which are most intense in the polar regions. The mass balance and dynamics of the large Antarctic Ice Sheet, and its paleoclimatic records, are important indicators of past and present global changes. Antarctica and Southern Ocean sediments contain the history of inception and growth of the ice masses and their subsequent fluctuations, and the long-term history of paleoclimate. The remarkable adaptations of Antarctic biota to extreme cold and drought may allow, through biotic monitoring, the detection of changes in the ocean and climate of Antarctica. ®1987 by AAAS.

Shelf Res., 7(11-12): 14451455. Open water sites are usually either dispersive (used in expectation that disposed sediments will not remain there, but will be transported out), or retentive sites (designed to ensure that disposed sediments mostly remain within the site). Choice of approach depends on character of site and sediment, and disposal quantities. Three disposal site studies illustrate the methods. In San Francisco Bay at the Alcatraz site, a dispersive condition is maintained by constraints on dredged mud characteristics developed from laboratory tests on erosion rates and from numerical modelling of the dump process. Field experiments were used to evaluate the management procedure. In Corpus Christi Bay a numerical model was used to determine how much disposed sediment returns to the navigation channel, and to devise a disposal location that will minimize that return. In Puget Sound a model was used to ensure that most of the disposed material remains in the site. New techniques, including piped disposal through 60 m of water, were investigated.

The National Oceanic and Atmospheric Administration is not adequately equipped to meet the needs of the future for research, services, and information relating to the natural environment. A restructuring is needed to fill gaps in its program, assure strengthened capabilities for global observations, and help the agency to balance its multiple missions, and order priorities in a manner consistent with the public interest. To implement those changes, a new legislative charter is needed defining new objectives and establishing the agency independent of the US Department of Commerce (DOT). Dept. of Atmos.

The advent of a broad range of new technologies over the past three decades for the exploration and development of remote Arctic and Antarctic areas has resulted in voyages to hitherto impenetrable areas in the Canadian Arctic, the Geographic North Pole, the Chukchi and Beaufort seas, the Weddell Sea and various stations around Antarctica, the North Sea, and the central Arctic Basin. The topics covered here reflect the influence of these developments in technology and include information on new polar ships; the risks and responsibilities
