Logistical Planning for Scientific Drilling in Lake Towuti, Indonesia

该项目的总体目标是通过在印度尼西亚最大的湖泊Towuti湖进行大陆科学钻探，在印度尼西亚中部建立更新世晚期跨越多个冰川-间冰期循环的陆地气候和气候变化的新记录。Towuti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非常高，并且位于东苏拉威西蛇绿岩内，引起了碳，铁，铬和其他金属的重要地球化学循环。最近的地球物理和活塞取芯调查，加上一个国际研讨会，已经制定了Towuti钻井项目背后的科学原理和假设。这项规划赠款将提供资金，与钻井工程师和工作人员一起对Towuti湖进行实地考察，为Towuti制定后勤可行的钻井计划，并为2013年提交的钻井提案制定现实和具有成本效益的预算。特别是，该合同将为首席PI和DOSECC勘探服务（DES）工作人员两次前往Towuti湖提供资金，以：1）在Towuti湖上确定建造、部署和回收钻井驳船的地点，以确定与驳船部署有关的现场改进的当地承包商（如码头建设），并为这些活动制定预算;2）为Towuti湖附近的钻井驳船船员制定具体的住房计划和预算; 3）与当地矿业公司PT Vale Indonesia Tbk就运输、进出口、供应和其他当地需求方面的后勤支持敲定协议;4）确定重型设备供应、燃料供应和其他服务的当地承包商，并获得这些服务的报价; 5）获取有关Towuti钻井项目等大型国际项目许可程序的最新信息;6）最终确定并核实Towuti钻井项目的预算，以便向国际大陆钻井计划，NSF和其他国家机构提交钻井建议。

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.
