Antarctic Expedition Security Guarantee Marine Information Collection and Analysis Forecasting

From the perspective of global level on digital Earth and Earth big data, this paper elaborated the development process of previous Antarctic expeditions on digitization and big data of products (services) provided by the National Center for Marine Environment Forecasting of China in the past 36 years, including marine route monitoring and forecasting guarantee, "sea-land investigation" monitoring and forecasting guarantee, traffic monitoring and forecasting guarantee for harbor unloading and "land-air storage and transportation" of investigation ship (team); in which, this paper elaborated the source and role of forecasting big data on cruising observation, localized observation, station area observation, mobile observation, as well as big data reanalysis of satellite remote sensing information, besides, the practical effects of various products were elaborated; moreover, the briefly introduction of the construction progress and work status of scientific investigation stations in Antarctica, especially meteorological observation and forecast stations in China was given. Main achievements: Firstly, creatively completion of 36 batches of marine and atmospheric forecast and guarantee tasks for Antarctic expeditions in China; secondly, establishment of the environmental monitoring and forecasting guarantee system of "sea-air" for several maritime routes of Antarctic expeditions in China, that of "sea-land-air" for the surrounding Antarctic continent, and that of "land-air" for the Antarctic bay to the inland depth hinterland.
