摘　　要：大洋科学钻探是一项对海洋底部进行科学探测和研究的重要手段,在地球科学、生命科学、资源勘探等诸多领域具有极其重要的意义。井下长期观测装置(CORK)是大洋科学钻探的重要补充,实现对海底环境从短期取样到长期动态观测的转变。过去几十年间,海底观测设备的技术手段不断提升,在初始CORK研发的基础上衍生出了另外4个新的版本,从最初的单一地层取样,发展到多地层取样,同时还可以进行原位测试。由我国主导的新一轮大洋钻探计划将要开始实施,亟需加大CORK技术的攻关力度,利用我国自己的资源和人才构建海底CORK观测系统,为尽快跻身世界海洋强国行列奠定坚实基础。Ocean scientific drilling is an important means of scientific exploration and research of the ocean floor,and has extremely important significance in many fields such as earth science,life science,and resource exploration.Circulation Obviation Retrofit Kit(CORK)is an important supplement to ocean scientific drilling.CORK can achieve the transformation from short-term sampling to long-term dynamic observation of the seabed environment.Over the past few decades,the technological means of underwater observation equipment have also been continuously improved in this process.CORK has derived four new versions based on the initial development of CORK,which have evolved from single layer sampling to multiple layer sampling and can also perform in-situ testing.The new round of ocean drilling program led by our country is about to be implemented,and it is urgent to increase the research and development efforts of CORK technology,use our own resources and talents to build an underwater CORK observation system,and lay a solid foundation for quickly entering the ranks of world maritime powers.
