*** 9873071 This award, provided by the Office of Polar Programs of the National Science Foundation, supports the continuation of activities of a committee of marine geologists, designated SHALDRIL II (for "shallow drilling"), to investigate the technical feasibility of conducting shallow drilling operations from US Antarctic Program (USAP) vessels in support of scientific research. Shallow drilling for paleoclimatic and paleoenvironmental records on the Antarctic continental margins has been identified in a number of venues as being of high importance. These records are essential for constructing models of ice sheet advance and retreat and for constraining paleoclimatic conditions from the earliest Cenozoic (65 million years ago) to the very recent past. The SHALDRIL (shallow drilling) Committee began work in 1996 as an offshoot of other community based Antarctic geology planning efforts. With support from a previous workshop award, the committee commissioned a technical evaluation, by a professional engineer, of available drilling systems and their suitability and compatibility for use on USAP ships. The results of this evaluation were presented at a meeting held at Florida State University on February 28, 1998. The engineering report represented an extensive investigation of existing and developing ship-based drilling technology with the main conclusion being that no extant drilling systems could be deployed on US vessels at present, but that two promising systems were to undergo field testing by their manufacturers during the coming year (1998). In addition, however, there were other systems available that could be used by third party ships, essentially specialized drilling ships, for Antarctic work. The SHALDRIL Committee concluded, therefore, that the best course of action was to continue to observe and evaluate the technical development of promising drilling systems. Furthermore, the Committee determined to undertake further assessments of potential areas for shallow dri lling, with the goal of specifying in more detail categories of suitable scientific drilling targets in various settings (geographic region, water depth, ice conditions, etc.) around the Antarctic margin. The committee intends to continue its work with the intention of holding a follow-up workshop meeting after the field tests during 1998 are completed. The Committee continues to interact with individuals and groups in the community to ensure that the scientific perspectives and rationale for drilling are as complete as possible. The workshop will occur between late 1998 and mid 1999. ***

*** 9873071该奖项由美国国家科学基金会极地项目办公室提供，支持海洋地质学家委员会继续开展活动，命名为SHALDRIL II（用于“浅层钻探”），以调查从美国南极计划（USAP）船只进行浅层钻探作业的技术可行性，以支持科学研究。 在南极大陆边缘进行浅层钻探以记录古气候和古环境，已在若干地点被确定为具有高度重要性。 这些记录对于构建冰盖前进和后退的模型以及约束从最早的新生代（6500万年前）到最近的过去的古气候条件至关重要。 SHALDRIL（浅钻）委员会于1996年开始工作，作为其他社区南极地质规划工作的一个分支。 在以前的研讨会奖励的支持下，委员会委托一名专业工程师对现有的钻井系统及其在USAP船舶上使用的适用性和兼容性进行技术评估。 1998年2月28日在佛罗里达州立大学举行的一次会议上介绍了这一评价的结果。 该工程报告代表了对现有和正在开发的船基钻井技术的广泛调查，主要结论是，目前没有现存的钻井系统可以部署在美国船只上，但两个有前途的系统将在明年（1998年）由其制造商进行现场测试。 然而，除此之外，还有其他系统可供第三方船只使用，主要是专门的钻探船，用于南极工作。 因此，SHALDRIL委员会的结论是，最好的行动方针是继续观察和评价有前途的钻井系统的技术发展。 此外，委员会决定进一步评估可能进行浅层钻探的地区，目的是更详细地说明各种情况下（地理区域、水深、冰况等）的适当科学钻探目标类别。在南极洲边缘。 委员会打算继续其工作，以便在1998年的实地试验完成后举行一次后续讲习班会议。 委员会继续与社区中的个人和团体进行互动，以确保尽可能全面地了解钻探的科学观点和理由。 讲习班将于1998年底至1999年年中举行。 ***
