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

Description: Das Projekt "Sub project: Compact Multipurpose Sub-Sampling and Processing of In-Situ Cores" wird vom Umweltbundesamt gefördert und von Technische Universität Berlin, Institut für Mechanik, Fachgebiet Kontinuumsmechanik und Materialtheorie durchgeführt. 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.
