Summary: In several years of drilling into the sediments overlying the oceanic crust the DSDP has established the geological youthfulness of the crust in comparison to most continental rocks and has helped confirm that sea-floor spreading and widespread crustal motions have occurred. These results, which became apparent early in the project, gained for the DSDP a reputation as one of the more successful examples of big science. More recent results, however, have been relatively modest. Among the highlights of the Glomar Challenger's recent cruises were the results of two legs of drilling in Antarctic waters which documented the glaciation of Antarctica for at least the past 20 m.y. and confirmed the separation of first New Zealand, between 60 and 80 m.y. ago, and then Australia from Antarctica. Possible explanations for the lag in research are delays in making samples available to the scientific community, slow responses on the part of scientists, and a lack of planning for how to use the cores and how to facilitate follow-up studies. Efforts to alleviate this situation include facilitating the distribution of cores; constructing a computerized data retrieval system that will aid those seeking to study the cores and will produce maps, depth profiles, and similar guides to the data; and an expanded charter with multinational participation in the project's scientific direction and funding, as the International Program of Ocean Drilling.
