中国大口径沉积物柱状取样技术取得新突破
中国科学院海洋研究所近日宣布，其研发的大口径沉积物柱状取样系统在黄海南部海域完成海上试验验证，成功获取单柱、连续、低扰动500毫米大口径柱状沉积物7.89米，创造了黄海南部海域具有方位和姿态信息的大口径柱状沉积物最长纪录。
该系统由取样器、导向器、钻杆、绞车、控制系统等组成，可实现对海底沉积物进行大口径、连续、低扰动的柱状取样，为海洋地质、古海洋学、古气候学等领域提供高精度、高分辨率的沉积物样品。
此次试验验证在黄海南部海域水深约50米的海底进行，取样器成功获取了从海底表层到7.89米深处的连续沉积物柱状样品。样品具有良好的柱状结构和连续性，为后续的沉积物年代学、古环境重建和古气候变化研究提供了宝贵的资料。
该系统的成功研发填补了我国在黄海南部海域大口径沉积物柱状取样技术领域的空白，为我国海洋地质和古海洋学研究提供了重要支撑。未来，该系统将继续在我国其他海域和深海进行试验验证，为我国海洋科学研究提供更加全面的数据支持。

**News Content:** China’s large-diameter sediment column sampling technologyhas made a new breakthrough.
The Ocean Institute of the Chinese Academy of Sciences recently announced that its developed large-diameter sediment column sampling system has completed sea trials in the southern Yellow Sea, successfully obtaining a single, continuous, low-disturbance 500 mm large-diameter columnar sediment of 7.89 meters, setting a new record for the longest large-diameter columnar sediment with orientation and attitude information in the southern Yellow Sea.
The system consists of a sampler, guide, drill rod, winch, and control system, and can perform large-diameter, continuous, low-disturbance columnar sampling of seabed sediments, providing high-precision, high-resolution sediment samples for fields such as marine geology, paleoceanography, and paleoclimatology.
The trial was conducted in the southern Yellow Sea at a water depth of approximately 50 meters. The sampler successfully obtained a continuous columnar sediment sample fromthe seabed surface to a depth of 7.89 meters. The sample has a good columnar structure and continuity, providing valuable data for subsequent sediment chronology, paleoenvironmental reconstruction, and paleoclimate change research.
The successful development of this system fills the gap in China’s large-diameter sediment column sampling technology in the southern Yellow Sea and provides important support for China’s marine geology and paleoceanography research. In the future, the system will continue to be tested in other sea areas and deep seas in China, providing more comprehensive data support for China’s marine scientific research.
