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.

TechnischeUniversität柏林在2001/2005年的欧盟项目风信子中开发了新闻界（加压核心亚采样和挤出系统）。在2005年5月测试了转移和子采样的可行性，结果良好。在维多利亚州维多利亚州的DFG资助的IODP应用程序期间，在科学海洋钻探中，额外的污染减少和控制改善了对科学海洋钻探的媒体媒体，B. C.随后作为NGHP Expedition 01的一部分的部署在11/2006证实了该系统的可用性，并可以通过使用可靠的投资方法成功地满足对原始深层生物圈样品的需求。此外，它表明了对易于处理，经济和广泛适用的系统的迫切需求，并有可能成为标准设备。紧凑型多功能子采样和原地核心的处理第2页，共34页，以保持竞争力，现在必须合并获得的专家知识。因此，首先提出了通过缩小系统的规模和重量来定制深层生物圈沉积物样品的加压传输，以减少后勤和财务费用，并通过需要较小的操作空间来增加应用领域（例如，20英尺而不是40英尺的40英尺代替40英尺的容器，在船上运营）。其次，不可避免的易于断层切割机制的重新设计也应与系统调整以切割较强的核心（例如ICDP）的调整。第三，为了运输加压加压的处理子样本，应设计小腔室（微型船尾），最后应实施潜水员传感器，以使系统对广泛的用户更具吸引力并减少其相互依存关系。
