National Marine Data and Information Service

As the third center for oceanography of the World Data Center following WDC-A of the United States and WDC-B of Russia, WDC-D for oceanography boasts long-term and stable sources of domestic marine basic data. The State Oceanic Administration now has long-term observations obtained from the fixed coastal ocean stations, offshore and oceanic research vessels, moored and drifting buoys. More and more marine data have been available from the Chinese-foreign marine cooperative surveys, analysis and measurement of laboratory samples, reception by the satellite ground station, aerial telemeter and remote sensing, the GOOS program and global ships of opportunity reports, etc; More marine data are being and will be obtained from the ongoing “863” program, one of the state key projects during the Ninth Five-year plan and the seasat No 1 which is scheduled to be launched next year. Through many years’ effort, the WDC-D for oceanography has established formal relationship of marine data exchange with over 130 marine institutions in more than 60 countries in the world and is maintaining a close relationship of data exchange with over 30 major national oceanographic data centers. The established China Oceanic Information Network has joined the international marine data exchange system via Internet. Through these channels, a large amount data have been acquired of through international exchange, which, plus the marine data collected at home for many years, has brought the WDC-D for Oceanography over 100 years’ global marine data with a total data amounting to more than 10 billion bytes. In the meantime, a vast amount of work has been done in the standardized and normalized processing and management of the data, and a series of national and professional standards have been formulated and implemented successively. Moreover, appropriate standards and norms are being formulated as required.

作为继美国WDC-A中心和俄罗斯WDC-B中心之后的全球第三个海洋学数据中心，WDC-D海洋数据中心拥有长期稳定的国内海洋基础数据来源。国家海洋局目前拥有来自固定海岸海洋站、海上和海洋研究船、锚泊和漂流浮标的长久观测数据。随着中外交海合作调查、实验室样品的分析与测量、卫星地面站、航空遥测和遥感、全球海洋观测系统（GOOS）计划以及全球机会航船报告等渠道，越来越多的海洋数据得以获取；同时，正在进行的“863”计划（国家第九个五年计划期间的国家重点工程）以及明年计划发射的海洋卫星一号，也将进一步增加海洋数据量。经过多年的努力，WDC-D海洋数据中心已与世界60多个国家的130多个海洋机构建立了正式的海洋数据交换关系，并与30多个主要国家海洋数据中心保持着密切的数据交换联系。通过互联网，中国海洋信息网络已接入国际海洋数据交换系统。通过这些渠道，通过国际交流获得了大量数据，加之多年来在国内收集的海洋数据，WDC-D海洋数据中心积累了超过100年的全球海洋数据，数据总量超过100亿字节。与此同时，在数据的标准化和规范化处理与管理方面也做了大量工作，并相继制定和实施了国家及行业标准。此外，根据需要，正在制定相应的标准和规范。
