Development of a deep drill in the United States would bring scientific benefits in much greater proportion than its incremental cost, when scaled bv present expenditures in the polar regions. Without a deep drill, the United States will continue to play a secondary role in the study of pre-Holocene ice.

The United States should continue to develop capabilities for measurements of gases including chemical and isotopic composition, such as oxygen isotopes of the trapped air (Bender and others, 1979) and climatically active trace gases (Kahlil and Rasmussen, 1983a, b)

The data should be fed into mass and heat flow models to determine what complexities might exist in the subsurface flow and to verify that large amounts of the oldest ice near the bed have not been melted off the bottom. Data from pits, shallow and intermediate depth cores should be gathered from an array of locations around a proposed deep drill site to establish regional stratigraphic continuity and gradients in relation to current climate.

Ice flow and temperature modeling directed specifically at ice core analysis is not highly developed anywhere, but there are productive efforts in a number of countries including the United States. This is an area the United States can easily advance.

SCIENTIFIC INTERFACES AND PLANNING There are important needs for scientific interfaces between ice core researchers and others focusing on paleoclimate data. These interfaces are needed not only for optimum scientific utilization of ice core data, but also to promote development of the most forward looking measurement and interpretation techniques and perspective in scientific planning.

efforts in ice coring have lagged behind those in other countries may in part arise from the splintered approach in the United States. It is recommended that the future management of the U.S.
