摘　　要：海底观测科学正朝着多元、立体、实时、长期、持续的趋势发展。加拿大"海王星"海底观测网(NEPTUNE Canada)是世界上第一个区域性海底电缆观测网络,位于加拿大西海岸20万km2的胡安·德富卡板块的北部,拥有全长800 km的主干网,5个海底观测站,自2009年12月业务运行以来为海洋学界的科学家们源源不断地提供着各种宝贵数据。首先对该系统工程的建设规模等基本构架进行简要介绍,然后从科学与机遇、关键技术、安全措施、业务运行与管理等方面阐述了该网络工程在设计、建造和运行整个过程中的几个主要关键问题,希望以此为我国海底观测工程的建设提供参考。NEPTUNE Canada is the world＇s first regional cabled undersea observatory network with a 800 km-loop backbone cable and five nodes on the northern part of the 200,000 km2 Juan de Fuca tectonic plate off Canada＇s west coast. It has been continuously providing various ocean environmental data to the science community since 2009 when it was operational for users, which promotes transformative ocean research. The NEPTUNE Canada＇s basic conditions including the region and scale are briefly presented, then the main components from design and construction to operation are illustrated in the aspects of scientific objectives and opportunities, technological challenges, safety measures, as well as operations and management. Some experiences are provided as reference for the olannin~ and construction of seafloor observatory projects in China.
