Abstract:

The South China Sea is the core interest of China. Since the 1950s, dozens of large-scale comprehensive marine scientific surveys in the South China Sea and its affiliated islands have been organized. A large number of important raw data were obtained. However, early data has not yet been digitized, with varying standards for data recording, quality control, and archiving, and is even scattered or on the verge of loss of original materials. There is an urgent need for rescue and reorganization. The “Reorganization of historical data from scientific investigations of the South China Sea and its affiliated islands and reefs” has completed the standardized compilation of historical data from 353 projects, 664 voyages, and over 200 elements from 1950 to 2019. It has constructed a comprehensive database of first-hand surveyed and valuable scientific data, including hydrometeorology, marine chemistry, bioecology, fishery resources, geological environment, and geological samples of islands and reefs. At the same time, scientific analysis of the data was completed, and some new analytical data products were formed. A set of 12 books titled “Compilation of Historical Materials for the South China Sea Scientific Expedition” and 7 other monographs were published. This series of articles is divided into three parts. Article 1 focuses on the systematic compilation of historical data, and briefly discusses the implementation steps of standardized compilation, and proposes the corresponding strategies for technical difficulties; Article 2 briefly discusses the research and practice of the South China Sea ocean data governance technology for scientific management of integrated data; Article 3 briefly discusses the construction practice and innovative application of “Digital South China Sea” for the sharing service of integrated data. This series of articles comprehensively discusses the research process and practical experience of the comprehensive database and “Digital South China Sea”, providing reference for the data standardized compilation of the relevant marine scientific investigations.

Key words: South China Sea, scientific investigation, historical data, system reorganization, technology application
