formed: boost for marine science. NOAA, 10(6): 6-9.

NOAA's Regional Undersea Research Program, underway in 1981, will consist of facilities (e.g., habitats, submersibles, research vessels, diver-related equipment) at 4 institutions: Fairleigh Dickinson University's Hydrolab; the Southeastern Undersea Research Facility (SURF) at the University of North Carolina at Wilmington; the Western Regional Undersea Laboratory (WURL) at the University of Southern California; and the University of Hawaii's Hawaiian Undersea Research Laboratory (HURL). The network is designed to provide scientists with a diverse ensemble of facilities for undersea research. Facilities and programs are briefly described. NOAA Undersea Res. Program Office, Washington, D.C., USA. (smf)

81:6794 Thoroughgood, C.A., 1981. The case for [the U.S.]

Sea Grant [Program]. Mar. Technol. Soc. J., 15(1):42-45.

The author finds that the Reagan administration's termination of Sea Grant 's funding on the grounds that it is primarily of regional value is not justified. Sea Grant 's history, accomplishments and impacts are recounted. Council of Sea Grant Directors, USA. (smf)

81: 6795 Anonymous, 1981. Cable-free TV from beneath the

sea. New Scient., 90(1259):p.840.

Microprocessor-based equipment (coupled with a conventional camera) digitally codes a low-fre- quency sonar pulse to transfer picture information from depths as great as 1200 m to the surface, eliminating the expense and inconvenience of cable links and dynamically positioned ships. The cable- free system, developed by Thomson-CSF, will be installed on a drill ship for final trials and could be marketed in 1982. (smf)

Changes in the design of oil production platforms are followed from the beginning of offshore drilling in Lake Maracaibo through development in the Gulf of Mexico up to exploration in the North Sea during the early 1960's. Geotechnical considerations and improvements in hardware may change the struc- tures back to a gravity type used earlier. Dept. of Engrg. Sci., King's College, London Univ., London, UK. (rjs)

mechanics and the solving of industrial and environmental fluid-flow problems. J. Fluid Mech., 106:103-130.

This personal essay on the occasion of the journal 's 25th anniversary considers the industrial and envi- ronmental control and exploitation of fluid flow, and how the scientific study of fluid mechanics has contributed to these. The converse is also discussed: certain industrial (and environmental) problems and their solutions have stimulated fluid mechanics research and ultimate understanding. The author urges closer rapport in the future between fluid mechanics theoreticians and practical engineers. Dept. of Appl. Math., Univ. of Cambridge, Silver St., Cambridge CB3 9EW, UK. (sir)
