This award, provided by the Office of Polar Programs of the National Science Foundation, provides support for a US research-planning workshop for Antarctic geological drilling. Geological drilling to recover core for scientific investigations was successfully conducted in the McMurdo Sound Region during 10 austral summers over a 28-year period since 1973. The sea-ice has been used successfully as a drilling platform for seven drill-holes in this area. Experience gained during these projects forms the basis for developing new drilling technology to advance this approach. The ANDRILL (ANtarctic DRILLing) Project considers future drilling from sea-ice, ice shelf and land platforms within its "McMurdo Sound Portfolio". This award provides funds for organizing and operating a workshop to develop the US science plan for the McMurdo Sound Portfolio of the ANDRILL Initiative. It has been advertised widely across the US Antarctic science community as well as beyond, to the general US geoscience community, and it will be open to all interested individuals. The aim of the workshop is to bring together scientists to: (1) discuss and refine the scientific goals and objectives of the McMurdo Sound Portfolio; (2) to inform the US science community of past and planned ANDRILL activities; (3) provide a vehicle for the distribution of information to scientists new to Cenozoic geoscience in Antarctica; (4) devise a plan agreeable to the US community for the structure of the US ANDRILL program, its style of funding and mode of operation; and (5) prepare a report that will summarize the interest and potential contributions of US scientists to this program, and provide guidelines as to how scientists can participate in the program.ANDRILL is an international consortium with objectives to recover stratigraphic core records for use in interpreting Antarctica's past climatic, glacial, and geological history over the past 50 million years and at varying scales of age resolution (0.1 to 100 k.y.). Understanding the past history of ice volume variation in Antarctica and associated physical changes in this region is critical to proper assessment of the global climate system and interaction of ice sheets with the ocean, atmosphere and biosphere. ANDRILL will proceed in three phases: geophysical and site surveys (2001-2004), drilling and core recovery (2003-2007), and climate and glacial modeling and integration of recovered data into global records of climate change (2005-2009). For the past 40 million years the Antarctic Ice Sheet has played a critical role in regulating global climate and sea level. Climatic warming is expected to be most pronounced in polar regions; Antarctic temperatures may rise by the end of the century to levels that have not been achieved for several million years. It is therefore vital that we understand the past response of the Antarctic ice sheet to climatic change in order to provide constraints on models that predict the future. ANDRILL currently plans 4 seasons of drilling under the "McMurdo Sound Portfolio", in the regions of New Harbor, Windless Bight, Mackay Sea Valley, and on the Southern McMurdo Ice Shelf. This Portfolio proposes more than ten individual drilling targets that will require varied drilling equipment and strategies. Most of these targets have several common requirements, including drilling through hundreds of meters of water (up to 1000 m), and recovering continuous core starting from the sea-floor to depths of as much as 1000 m. Through subsequent Portfolios, the life of ANDRILL and this new drilling system will likely continue towards the year 2020. Support for programs of this scale must come from contributions of several nations. To date, the ANDRILL International Consortium includes as member nations the USA, United Kingdom, New Zealand, Italy and Germany, and it invites membership from any interested nation. Similar to the Cape Roberts Project (CRP), close interaction of a diverse team of research scientists, postdoctoral scientists, graduate and undergraduate students will provide excellent opportunities for education and on-site training. REU appointments will target underrepresented groups in the geosciences. ANDRILL plans to expand the educational and outreach component beyond that of CRP by direct on-site and remote learning opportunities through member-nation initiatives and ANDRILL sponsored outreach and education. An "on-ice" team of scientists would prepare the core and provide initial description and characterization. Samples would be shipped to "off-ice" scientists to study and present results at the first of two science workshops to be hosted at member-nations home academic institutions on a rotating basis. Publication of initial results would be followed by presentation of results in major scientific journals and at professional meetings.

该奖项由国家科学基金会极地计划办公室提供，为美国研究计划的讲习班提供了支持。自1973年以来，在28年的澳大利亚夏季，在麦克默多声音地区成功进行了地质钻探以恢复科学研究的核心。在这些项目期间获得的经验构成了开发新钻探技术以推进这种方法的基础。 Andrill（南极钻探）项目考虑了其“ McMurdo Sound Portfolio”中的Sea-Ice，Ice Beshelf和Land Platforms的未来钻探。该奖项为组织和经营研讨会提供了资金，以制定Andrill倡议的McMurdo Sound Portfolio的美国科学计划。它在美国南极科学界以及整个美国一般地球科学界都广泛广泛传播，并将向所有感兴趣的人开放。研讨会的目的是将科学家汇集在一起​​：（1）讨论和完善McMurdo Sound Portfolio的科学目标和目标； （2）告知美国科学界过去和计划的安德里尔活动； （3）提供了向南极洲新生代新生科科学的科学家分配信息的工具； （4）设计一个与美国社区的计划，以实现美国安德里尔计划的结构，其资金风格和运营方式； and (5) prepare a report that will summarize the interest and potential contributions of US scientists to this program, and provide guidelines as to how scientists can participate in the program.ANDRILL is an international consortium with objectives to recover stratigraphic core records for use in interpreting Antarctica's past climatic, glacial, and geological history over the past 50 million years and at varying scales of age resolution (0.1 to 100 k.y.).了解南极冰量变化的过去历史以及该区域中相关的物理变化对于正确评估全球气候系统以及冰盖与海洋，大气和生物圈的相互作用至关重要。安德里尔（Andrill）将分为三个阶段：地球物理和现场调查（2001-2004），钻探和核心回收（2003-2007），以及将回收数据的气候和冰川建模以及融合到气候变化的全球记录中（2005-2009）。在过去的4000万年中，南极冰盖在规范全球气候和海平面上发挥了至关重要的作用。在极地地区，气候变暖预计最为明显。南极温度可能在本世纪末升高到几百万年没有达到的水平。因此，至关重要的是，我们了解南极冰盖对气候变化的过去反应，以便对预测未来的模型提供限制。 Andrill目前计划在新港，无风野，Mackay Sea Valley和Southern McMurdo Ice Bhelf的“ McMurdo Sound Portfolio”下进行4个季节的钻探。该投资组合提出了十多个单独的钻井目标，需要各种钻井设备和策略。这些目标大多数都有几个共同的要求，包括在数百米的水（最高1000 m）中进行钻孔，并从海底到深度高达1000 m的连续核心恢复。通过随后的投资组合，安德里尔（Andrill）和这个新的钻探系统的生活可能会持续到2020年。对此规模的计划的支持必须来自多个国家的贡献。迄今为止，安德里尔国际联盟包括美国，英国，新西兰，意大利和德国的成员国，并邀请任何感兴趣的国家的会员资格。类似于罗伯茨角（Cape Roberts Project）（CRP），多样化的研究科学家，博士后科学家，研究生和本科生的多样化团队的密切相互作用将为教育和现场培训提供绝佳的机会。 REU任命将针对地球科学中代表性不足的群体。安德里尔（Andrill）计划通过成员民族举措直接现场和远程学习机会将教育和外展部分扩展到CRP之外，而安德里尔（Andrill）赞助了外展和教育。一个“冰上”科学家团队将准备核心，并提供最初的描述和特征。样本将被运送到“冰上”科学家，以研究和介绍两个科学研讨会中的第一个将在成员国家庭学术机构举办的第一个。在主要科学期刊和专业会议上，将介绍初始结果的发布。
