Compact Multipurpose Sub-Sampling and Processing of In-Situ Cores

柏林工业大学于2001/2005年在欧盟的风信子项目中开发了PRESS(加压岩芯亚采样和挤压系统)。2005年5月对转移和二次抽样的可行性进行了检验，取得了良好的效果。在DFG资助的不列颠哥伦比亚省维多利亚市IODP应用期间，额外的污染减少和控制改善了科学海洋钻探中天然气水合物和地球微生物研究的压力(11/2005，第311段，卡斯卡迪亚边缘天然气水合物)。随后在2006年11月11日作为NGHP探险01的一部分进行的部署证实了该系统的可用性，并可以通过使用可靠的调查方法成功地满足对原始深层生物圈样品的需求。此外，它还表明，迫切需要易于操作、经济和广泛适用的系统，并有可能成为标准设备。现场岩心的紧凑多用途分采样和处理第34页第2页为了保持竞争力，现在必须巩固所获得的专业知识。因此，建议首先通过缩小系统的尺寸和重量来定制深层生物圈沉积物样本的加压转移，以减少后勤和财政费用，并通过要求较小的操作空间(例如，20英尺而不是40英尺的集装箱，离岸、船上操作)扩大应用领域。其次，对易出现故障的切割机构进行不可避免的重新设计的同时，还应调整系统以切割较硬的岩芯(例如ICDP)。第三，应设计小室(微型容器)，以便运送加压处理的子样品，最后，应安装不同的传感器，以使系统对更广泛的用户更具吸引力，并减少他们之间的相互依赖。

Technische Universität Berlin has developed PRESS (Pressurized Core Subsampling and Extrusion System) in the EU project HYACINTH in 2001/2005. Feasibility of transfer and sub-sampling was tested in May 2005 with good results. Additional contamination reduction and control have improved the PRESS for gas hydrate and geo-microbiological research in scientific ocean drilling during the DFG funded IODP application in Victoria, B. C. (11/2005, Leg 311, Cascadia Margin Gas Hydrates). A subsequent deployment as part of the NGHP expedition 01 in 11/2006 substantiated the usability of the system and could successfully accommodate the demand for pristine deep biosphere samples by using reliable investigation methods. Moreover it showed the desperate need for systems that are easy to handle, economically and broadly applicable and have the potential to become standard devices. Compact Multipurpose Sub-Sampling and Processing of In-Situ Cores Page 2 of 34 In order to stay competitive the acquired expert knowledge now has to be consolidated. Consequently it is proposed, first, to customize the pressurized transfer of deep biosphere sediment samples by scaling down the system in size and weight so that logistical and financial expenses are reduced and the field of application is enlarged by requiring a smaller operating space (e.g., 20ft instead of 40ft container, off shore, on board operation). Second, the inevitable redesign of the fault-prone cutting mechanism shall simultaneously be combined with an adjustment of the system to cutting harder cores (e.g., ICDP) as well. Third, small chambers (micro-vessels) shall be designed in order to transport the processed sub-samples pressurized and, finally diverse sensors shall be implemented to make the system more attractive for a broad spectrum of users and to reduce their interdependence.
