This award will provide management and operational support for the conduct of continental scientific drilling projects. Continental Scientific Drilling (CSD) has a long history producing transformative science. The CSD community is large and has diverse interests, but there are significant barriers to implementing successful projects. These barriers include coordination throughout the community, technical hurdles in planning and budgeting, and difficulties in implementing and managing drilling operations. DOSECC supports the scientific drilling community by: encouraging and nurturing community efforts to develop CSD projects, preparing drilling plans and budgets, designing and fabricating equipment, and conducting scientific drilling operations. DOSECC's mission is to provide these services to the community to improve the efficiency of CSD projects and allow Principal Investigators to focus on scientific investigations.Drilling is the only method available for directly accessing and sampling the subsurface. Scientific drilling on continents is critical for understanding the Earth's third dimension including stratigraphic succession (history of earth processes), sampling poorly or non-exposed intervals, and collecting rocks altered by surface weathering processes. Drilling is also the only means for sampling the climate proxies preserved in modern and ancient lakes. Future CSD projects will address transformative concepts in the earth sciences such as climate history, human origins and migration, mass extinctions and plume volcanism. Scientific drilling has important societal benefits, including monitoring of seismic and volcanic hazards, identification of natural resources, and determination of climate variability.

该合同将为开展大陆科学钻探项目提供管理和业务支持。 大陆科学钻探（CSD）在产生变革性科学方面有着悠久的历史。可持续发展委员会社区规模很大，利益各异，但在实施成功的项目方面存在重大障碍。这些障碍包括整个社区的协调、规划和预算方面的技术障碍以及实施和管理钻井作业方面的困难。 DOSECC通过以下方式支持科学钻探界：鼓励和培养社区努力开发CSD项目，编制钻探计划和预算，设计和制造设备，以及进行科学钻探作业。 DOSECC的使命是为社区提供这些服务，以提高CSD项目的效率，并使首席调查员能够专注于科学调查。钻探是直接进入地下并取样的唯一方法。在大陆上进行科学钻探对于了解地球的第三维至关重要，包括地层序列（地球过程的历史），采样不良或未暴露的间隔，以及收集因表面风化过程而改变的岩石。钻探也是对保存在现代和古代湖泊中的气候代用指标进行取样的唯一手段。可持续发展委员会未来的项目将涉及地球科学中的变革性概念，如气候历史、人类起源和迁移、大规模喷发和羽状火山活动。 科学钻探具有重要的社会效益，包括监测地震和火山灾害、查明自然资源和确定气候变化。
