Support for Scientific Drilling

[309707]钻探是进入地下完成各种科学目标的唯一手段。这些工作包括收集原始岩石和流体样本，安装用于监测和模拟动态地球过程的地下仪器。影响科学钻井项目成功的最重要的问题是技术复杂性、成本和合适钻井设备的可用性。DOSECC（地球大陆地壳钻探、观测和取样）是一家非营利性公司，其使命是为科学钻探界提供操作支持和专业设备。DOSECC目前有50个成员研究机构。该合同将为DOSECC未来五年的运营提供支持。DOSECC明确支持科学钻井社区的需求，提供有价值的技术和钻井支持。在过去的资助期间，DOSECC成功地完成了一些项目，包括古气候和构造研究的湖泊钻探、地质和地球化学模拟的深部取芯、监测火山灾害的仪器安装和大陆架采样。在目前的拨款期间，DOSECC将继续为陆地、湖泊和浅海环境提供专门的钻井系统。

0309707NielsonDrilling is the only means for accessing the subsurface to accomplish a variety of scientific goals. These include the collection of pristine rock and fluid samples and the installation of subsurface instrumentation for monitoring and modeling dynamic earth processes. Overriding issues that influence the success of a scientific drilling project are technical complexity, cost and availability of suitable drilling equipment.DOSECC (Drilling, Observation and Sampling of the Earth's Continental Crust) is a non-profit corporation whose mission is to provide operational support and specialized equipment for the scientific drilling community. DOSECC now has 50 member research institutions. This award provides support for the next five years of DOSECC operations. DOSECC has clearly supported the needs of the scientific drilling community, providing valuable technical and drilling support. During the past grant period, DOSECC has successfully completed a number of projects in lake drilling for paleoclimate and tectonic studies, deep coring for geologic and geochemical modeling, installation of instruments for monitoring volcanic hazards, and sampling on the continental shelves. During the present grant period, DOSECC will continue to provide specialized drilling systems for drilling on land, on lakes and in shallow marine settings.
