This proposal award provides funding to support the travel costs of six U.S. researchers to participate in a workshop in Bandung, Indonesia, in January 2012. The workshop is intended to develop a strategic plan for a new continental drilling project in Lake Towuti, Sulawesi, Indonesia, and will involve researchers from Indonesia, Canada, and Europe as well as the U.S. The geological record at Lake Towuti provides a unique opportunity to reconstruct climate change over multiple glacial-interglacial cycles in the Western Pacific, at the origin of the El Nino-Southern Oscillation. Drilling in Lake Towuti will identify the age and origin of the lake, the environmental and climatic context that shaped the evolution of its ecosystem, and changes in its geomicrobiology in response to climate variations over the past 60,000 years. This workshop will lay the groundwork for a major international research study that will yield important information about the atmospheric convection over Central Indonesia, which influences strongly the global atmospheric heat and water balances. The major costs of the workshop will be covered by the International Continental Drilling Program, which is based in Germany.Participation in this workshop by the U.S. researchers will ensure their access to the planned research and catalyze new intellectual collaborations of American faculty and students with their Indonesian counterparts by developing jointly the first scientific drilling project in the Western Pacific. Data generated by this program will contribute to a better understanding of global climate change over the centuries.

该提案奖为六名美国研究人员参加2012年1月在印度尼西亚万隆举行的研讨会提供差旅费。 该研讨会旨在为印度尼西亚苏拉威西岛Towuti湖的新大陆钻探项目制定战略计划，并将涉及来自印度尼西亚，加拿大和欧洲以及美国的研究人员Towuti湖的地质记录提供了一个独特的机会，以重建西太平洋多个冰川-间冰期周期的气候变化，在厄尔尼诺-南方涛动的起源。在Towuti湖钻探将确定湖泊的年龄和起源，塑造其生态系统演变的环境和气候背景，以及过去6万年来气候变化对其地质微生物学的影响。这次讲习班将为一项重大的国际研究奠定基础，这项研究将产生关于印度尼西亚中部上空大气对流的重要信息，这种对流对全球大气热量和水平衡产生重大影响。研讨会的主要费用将由总部设在德国的国际大陆钻探计划承担。美国研究人员参加这次研讨会将确保他们能够参与计划中的研究，并促进美国教师和学生与印度尼西亚同行的新的智力合作，共同开发西太平洋的第一个科学钻探项目。该计划产生的数据将有助于更好地了解几个世纪以来的全球气候变化。
