Like the planned conference itself, we address the possible scientific goals of a continued drilling program; we do not address funding or priority-sehing, issues that are beyond the scope of this short report. We do recognize that the cost implications of factors such as high operating costs and technology development needs would have to be considered in making a decision to include arctic ocean drilling in any future program.

Interpretation of these samples has provided a record of ocean crustal spreading as well as insights into the origin and history of different ocean basins. In addition, our knowledge of seawater chemistry, marine biology, marine geology, and the origin of submarine structures grew dramatically because of Ocean Drilling Program activities, making this one of the most important oceanographic research projects of the 20th century.

enable interpretation of past climatic systems that have influenced down core sediment records. THE IMPORTANCE OF DRILLING IN THE ARCTIC Any justification for the perpetuation of scientific ocean drilling in general should be based at least in part on the need for drilling in the Arctic Ocean.

The origin and evolution of the Arctic Ocean and its contribution to, or control of, Earth's modern climate can be interpreted from the results of Arctic Ocean drilling. For example: Knowledge of how and when the Arctic Ocean formed may be determined from a study of systems such as the Alpha-Mendeleyev Ridge system Knowledge of Arctic Ocean circulation, venting, and other oceanographic factors may be gained from study of the Lomonosov Ridge, a high standing barrier to oceanic circulation in the Arctic.

The sites of the oldest known Arctic Ocean sediment on the Alpha Ridge include some in water of less than 1 500m. In addition, submersible drilling rigs similar to the Russian GNPP Sevmorgeo might be usable in the Arctic Ocean (Nansen Arctic Drilling Implementation Plan, 1 997)

The scientific case for Arctic Ocean drilling is so compelling that it should proceed in spite of less than perfect site survey information. CONCLUSION The Polar Research Board believes that the continuation of an organized international program of scientific drilling is valuable because it will continue to provide important insights about Earth's past, present, and future.

From page 7... ...
This combination of factors strengthens the case for incorporating some Arctic Ocean drilling into any new program that might evolve.
