    by Robert N. Ginsburg From Southeast Asia to South Florida, coral reefs show signs of decline. Growing concern about the health of the world's reefs has mobilized the international scientific community. What can geology offer to the global effort to assess the state of these ecologically and economically valuable resources -- and preserve them for future generations?

    Is Ward Valley Safe? A Point/Counterpoint Discussion
    by Howard Wilshire and John B. Robertson The controversy over Ward Valley -- California's proposed disposal site for low-level radioactive wastes -- continues.

    by Peter K. Zawada Estimating the likelihood of floods in semi-arid South Africa is no easy task; annual rainfall (and river flow) can vary considerably from year to year and flood records are short or nonexistent. But studying the physical evidence from past floods can help hydrologists predict the probability and potential severity of future flooding.
