Ice Coring and Drilling Services

威斯康星大学将支持由NSF极地项目办公室资助的项目，该项目需要支持从冰川和冰盖中提取冰芯或钻探冰芯。这包括维护NSF目前的钻探系统库存，并使它们可用于科学项目，或为项目操作它们。预计这些项目将是多样化的，而且每年都会有所不同。它们将发生在两极，以及更温和和更高海拔的地点。威斯康星大学将与科学界合作，在正式提案提交给OPP之前定义要求、范围和解决方案。在合同的第一年将进行的其他工程开发将包括开发一种钻头，以便在极地降雪中快速打孔，以及另一种在南极冰盖上准备300米钻孔的系统，用于宽带地震计阵列。一个较长期的活动将是评估目前的5.2英寸深钻系统，以提出改进建议，并制定实施改进的发展计划。

ABSTRACTBentley00-03289The University of Wisconsin will support the project funded by Office of Polar Programs at NSF that require support taking ice-cores from, or drilling into, glaciers and ice-sheets. This involves maintaining the NSF's current inventory of drill systems and making them available to science projects, or operate them for projects. The projects are expected to be diverse, and to vary from year to year. They will occur at both poles, and at more temperate and high altitude sites. University of Wisconsin will work with the science community to define requirements, scope solutions before formal proposals are submitted to OPP. Additional engineering development that will occur during the first year of the contract will include the development of a drill to rapidly making shot-holes in polar firn, and another system to prepare a 300 meter bore-hole in the ice sheet at the South Pole for a broad-band seismometer array. A longer term activity will be to evaluate the current 5.2" deep drill system to recommend improvement, and make a development plan to implement the improvements.
