Contamination controlled sub sampling of pressurised cores from IODP Leg 311, Cascadia hydrates

IODP LEG 311，卡斯卡迪亚边缘水合物，提出改进并试点使用它S新颖而独特的加压井下岩心分压系统。柏林理工大学在2001/2005年的欧盟研究项目风信子项目中发展了新闻出版。正在于2005年4月和5月测试转移和分抽样任务的可行性，取得了良好的结果。拟议的额外减少和控制污染将提高在科学海洋钻探中对天然气水合物和地球微生物研究的压力的效用。污染控制应用了力学、流体力学、材料、灭菌和荧光等方法。计划于2005年10月至11月在不列颠哥伦比亚省维多利亚市进行试点使用，在科学钻探结束时和之后使用RV Jodes Resolve。与加拿大地质调查局、IODP-TAMU、美国和日本科学家311段的合作已经准备就绪。也应使用加的夫大学约翰·帕克斯教授开发的风信子下游微生物加压研究设备。英国国家环境研究委员会的J.Parkes目前正在提交一份类似的财政支持请求。

IODP Leg 311, Cascadia Margin Hydrates, offers to improve and pilot use it s novel and unique pressurised sub sampling PRESS-ystem for pressurised down hole cores. Technische Universität Berlin has developed PRESS in the EU research project HYACINTH in 2001/2005. Feasibility of transfer and sub sampling tasks are being tested in April and May 2005 with good results. Additional contamination reduction and control as proposed shall improve the utility of PRESS for gas hydrate and geomicrobiological research in scientific ocean drilling. Contamination control applies methods of mechanics, fluid mechanics, materials, sterilisation and fluorescence. Pilot use is being planned in Victoria, British Columbia, October to November 2005, at the end and after scientific drilling with RV Joides Resolution. Co-operation with the Canadian Geological Survey, with IODP-TAMU, US and Japanese scientists of Leg 311 has been prepared. Downstream microbiological pressurised research equipment of HYACINTH, developed by Prof. John Parkes, University of Cardiff, shall also be used. An equivalent request for financial support is being presently submitted by J. Parkes at NERC, the UK National Environmental Research Council.
