Development of a mobile, multi component Down-The-Hole coring rig for recovery of high quality, long soft sediment cores

对使用高质量和长期沉积物记录的多代理研究的需求需要创新的取心设备，这些设备可以实现更大范围的岩心回收，并且可以对松散沉积物进行经济有效的采样。该提案要求为开发和测试一种新型的、高流动性的、用于回收软沉积物的海上取心系统提供资金。目前已经过验证的手动操作活塞井盖将通过增加一种钻孔锤进行改进和改进，这种锤最初是为采矿业开发的，它直接向井盖顶部施加力，以穿透坚硬的地层，从而达到更深的深度。这种地下探测装置被设计成一个多组件系统，具有可移动的浮动平台以及易于移动和运输的附件。它将在陆地、湖泊和浅海环境中恢复20至100米长的连续沉积物岩心，水深可达300米。凭借其方法上的创新，该系统将缩小取心技术的差距，即使在偏远地区也能经济高效地回收软沉积物。将为SPP 1006提供一个取心装置，为海洋-大陆样带的新研究质量提供一个基础，从而为海洋和陆地研究界之间的合作发起一种势头。与市面上的取心工具相比，这种取心设备的成本要低得多。

The demand for multi-proxy-studies using high quality and long sediment records requires innovative coring devices that allow core recovery with extended reach and cost effective sampling of unconsolidated sediments. This proposal requests funding to develop and test a novel, highly mobile, offshore coring system for the recovery of soft sediments. A proven but so far manually operated piston corer will be modified and advanced by the addition of a down-the-hole-hammer, originally developed for the mining industry, that applies force directly to the top of the corer in order to penetrate hard layers and thus, reaching greater depths. This subsurface probing device is designed as a multi-component system with a mobile, floatable platform plus accessories that can easily be moved and transported. It will be engineered to recover continuous sediment cores of 20 to 100 m length on land, in lakes and shallow marine environments with water depths of up to 300 m. With its methodological innovation the system will close a gap in coring technology and allow cost-efficient recovery of soft sediments even in remote areas. The SPP 1006 will be supplied with a coring device that provides a base for new research qualities for ocean-continent-transects and thus, initiating a momentum for the cooperation between marine- and terrestrial-based research communities. This coring device will run on a much lower cost base compared to commercially available tools.
