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

Technische Universität Berlin于2001/2005年在欧盟项目HYACINTH中开发了PRESS（加压岩心取样和挤压系统）。2005年5月进行了转移和分采样可行性试验，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州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质微生物研究的PRESS （11/2005, Leg 311， Cascadia边缘天然气水合物）。随后在2006年11月，作为NGHP考察队01的一部分，该系统的部署证实了该系统的可用性，并通过使用可靠的调查方法成功地满足了对原始深层生物圈样本的需求。此外，它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。为了保持竞争力，现在必须巩固已获得的专业知识。因此，有人建议，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品的加压转移，从而减少后勤和财务费用，并通过需要更小的操作空间（例如，20英尺而不是40英尺的集装箱，离岸，船上操作）来扩大应用领域。其次，对易发生故障的切削机构的不可避免的重新设计应同时与系统的调整相结合，以切割更硬的芯（例如，ICDP）。第三，应设计小室（微容器），以便加压运输处理后的子样品，最后应实施各种传感器，使系统对广泛的用户更具吸引力，并减少它们之间的相互依赖性。

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.
