摘　　要：针对海底观测网建设过程中的多源异构数据集成、海量数据处理和科研协同工作等问题,构建了一个面向海洋观测的赛百平台(Cyberinfrastructure,CI)。通过整合底层分布式的计算、存储、数据、传感器等资源和设备,面向顶层特定的科研用户提供基于网络环境的高效计算服务、海量数据服务、科研应用服务等。通过集成科学工作流,开发数据分析模块,实现对海量观测数据的处理。运用虚拟组织技术,实现了基于网络的科研协同工作。实验结果表明:该系统可以显著提高海洋科研人员的工作效率。The cyberinfrastructure （CI） for seafloor observations needs to integrate multi-resource heterogeneous data, process massive amounts of data and foster cooperation to construct the seafloor observation network. Integration of distributed computing resources, storage resources, data resources and sensors in the system architecture is needed to provide network based computational services, massive data processing services and research opportunities for specific users. This paper shows how to integrate the scientific workflow and develop the data analysis modules for the massive data processing. A virtual organization is then used to achieve web-based research cooperation. Tests show that the prototype dramatically improves the efficiency of marine researchers.
