The overarching goal of this project is to develop new records of terrestrial climate andenvironmental change in central Indonesia spanning multiple glacial-interglacial cycles over the late Pleistocene through continental scientific drilling in Lake Towuti, the largest lake in Indonesia. Lake Towuti has long been recognized as a priority drilling site for a global lake drilling program due to its location in the climatically-important Indo-Pacific region, its extraordinarily high rates of biodiversity and biological endemism, and its location within the East Sulawesi Ophiolite, giving rise to important biogeochemical cycles of carbon, iron, chromium, and other metals. Recent geophysical and piston coring surveys, combined with an international workshop, have developed the scientific rationale and hypotheses behind the Towuti Drilling Project. This planning grant will provide funds to conduct site visits to Lake Towuti with drilling engineers and personnel to develop a logistically feasible drilling plan for Towuti, and to develop a budget that is both realistic and cost-effective for drilling proposals to be submitted in 2013. In particular, this award will provide funds for two trips to Lake Towuti for the lead PI and DOSECC Exploration Services (DES) staff to:1) Identify sites on Lake Towuti for constructing, deploying, and recovering a drilling barge, to identify local contractors for site improvements related to barge deployment (e.g. dock construction), and to develop a budget for these activities;2) Develop a concrete plan and budget for housing the drilling barge crew near Lake Towuti;3) Finalize agreements with PT Vale Indonesia Tbk, a local mining company, for logistical support in the areas of shipping, import/export, supplies, and other local needs;4) Identify local contractors for heavy equipment supply, fuel supply, and other services, and obtain price quotes for those services;5) Obtain up-to-date information on permitting procedures for large, international projects such as the Towuti Drilling Project;6) Finalize and verify a budget for the Towuti Drilling Project for drilling proposal submission to the International Continental Drilling Program, the NSF, and other national agencies.

该项目的总体目标是通过在印度尼西亚最大的湖泊托乌提湖进行大陆科学钻探，开发印度尼西亚中部跨越更新世晚期多个冰期-间冰期旋回的陆地气候和环境变化的新记录。托乌提湖长期以来一直被认为是全球湖泊钻探计划的优先钻探地点，因为它位于气候重要的印度太平洋地区，其生物多样性和生物特有性极高，而且位于东苏拉威西蛇绿岩内，产生了重要的碳、铁、铬和其他金属的生物地球化学循环。最近的地球物理和活塞取芯调查与国际研讨会相结合，形成了陶乌提钻探项目背后的科学原理和假设。该规划拨款将提供资金与钻探工程师和人员一起对陶乌提湖进行实地考察，为陶乌提湖制定一个逻辑上可行的钻探计划，并为 2013 年提交的钻探建议制定既现实又具有成本效益的预算。特别是，该拨款将为首席 PI 和 DOSECC 勘探服务 (DES) 工作人员提供两次前往陶乌提湖的资金，以：1) 确定托乌提湖的地点 建造、部署和回收钻井驳船，确定当地承包商进行与驳船部署相关的现场改进（例如码头建设），并为这些活动制定预算；2) 制定陶乌提湖附近钻井驳船船员住房的具体计划和预算；3) 与当地矿业公司 PT Vale Indonesia Tbk 敲定协议，在运输、进出口、运输等领域提供后勤支持。 供应和其他当地需求；4) 确定重型设备供应、燃料供应和其他服务的当地承包商，并获取这些服务的报价；5) 获取有关大型国际项目（例如 Towuti 钻探项目）许可程序的最新信息；6) 最终确定并核实 Towuti 钻探项目的预算，以便向国际大陆钻探计划、美国国家科学基金会和其他国家机构提交钻探建议。
