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.

使用高质量和长时间沉积物记录进行多代理研究的需求需要创新的取芯装置，以允许在扩展范围内进行岩心回收，并对松散沉积物进行成本效益高的取样。该提案要求提供资金，以开发和测试一种新型的、高度移动的海上取芯系统，用于软沉积物的回收。一种经过验证但迄今为止手动操作的活塞取样器将通过增加一个最初为采矿业开发的潜孔锤进行改进和改进，该潜孔锤直接向取样器的顶部施加力，以便穿透硬层，从而达到更大的深度。这种地下探测设备设计为多组件系统，具有移动的可浮动平台以及易于移动和运输的附件。它将被设计用于在陆地、湖泊和水深达300米的浅海环境中采集20至100米长的连续沉积物岩心。该系统在方法上的创新将填补取芯技术方面的空白，并使即使在偏远地区也能以具有成本效益的方式回收软沉积物。SPP 1006将配备一个取芯装置，为海洋-大陆-断面的新研究质量提供基础，从而为海洋和陆地研究界之间的合作提供动力。与市售工具相比，这种取芯装置的成本要低得多。
