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

Cascadia Margin Hydrates公司的IODP Leg 311提供了一种新型的、独特的加压取样系统，用于井下加压岩心，并对其进行了改进和试点。Technische Universität Berlin在2001/2005年欧盟研究项目HYACINTH中开发了PRESS。2005年4月和5月对转移和分采样任务的可行性进行了测试，取得了良好的效果。所提议的其他污染减少和控制将提高PRESS在天然气水合物和地质微生物科学海洋钻探研究中的效用。污染控制应用力学、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州进行试点使用，并在RV Joides Resolution的科学钻探结束后进行。与加拿大地质调查局、碘- tamu、美国和日本科学家的合作已经准备好了311号Leg。还将使用卡迪夫大学John Parkes教授开发的HYACINTH下游微生物加压研究设备。英国国家环境研究委员会（NERC）的j·帕克斯（J. Parkes）目前也提出了同样的财政支持请求。

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.
