Networking Observation and Applications of Chinese Ocean Satellites

This paper presents the networking observation capabilities of Chinese ocean satellites and their diverse applications in ocean disaster prevention,ecological monitoring,and resource development.Since the inaugural launch in 2002,China has achieved substantial advancements in ocean satellite technology,forming an observation system composed of the HY-1,HY-2,and HY-3 series satellites.These satellites are integral to global ocean environmental monitoring due to their high resolution,extensive coverage,and frequent observations.Looking forward,China aims to further enhance and expand its ocean satellite capabilities through ongoing projects to support global environmental protection and sustainable development.

Information System for Ocean Wave Resources and Its Application to Wave Power Utilization

An information system for ocean wave resources and its application to wave power utilization are introduced. It can manage, analyze and process the data in the monthly report of ocean wave observation records of the State Ocean Administration, and can provide various kinds of curves and numerical characters of statistics. This system has been put into utility in Guangzhou Institute of Energy Conversion (GIEC), the Chinese Academy of Sciences since 1996. An application example is given of the investigation and analysis on ocean wave resource of the Nan Ao Island, Guangdong Province, where a 100 kW onshore OWC (oscillating water column) wave power station will be built. The wave power distribution is obtained in different wave directions for different wave periods. It is found that 70 percent of the wave power comes from the direction of ENE, and more than 95 percent of the wave power is related with direction E. The average wave power density is about 3 kW/m, and more than 80 percent of the wave power is distributed in the wave periods of 4 second to 5 second. Based on the analysis of wave resources, a site on the east coast of the island and a design width of 20 m for the 100 kW station are suggested.

Vast Energy Resource Locked Below Ocean Floor

人们曾经一度担心:当深埋在地下的最后一滴石油用尽之后,人类将 如何发展.甚至如何生存。读了本文,也许你会觉得“杞人忧天”并非古人的故事。新一代的能源已经显露在地平线上。它正lie frozen in combustible(易燃的)ice crystals(晶体)below the ocean floor. 它的名称尚未确定:gas or methane(甲烷)hydrates(水合物;氢氧化物)。 人们如此推测它的由来:organic(有机体的)sediments(沉淀物)have beentrapped for many millions of years by pressure and cold. 这种新能源估计投入商业开采的年限是:15 years may be a reasonable goal“for commercial extraction”. 目前,世界油价连连飞涨,世界经济也深受影响,在此大背景下,这则消息就越发显得令人兴奋不已: While research is at an early stage—just compiling a round inventory(总量)of hydrate formations around the world will take decades—excitement is buildingand some scientists,including officials at the U.S.Energy Department,believelarge—scale commercial exploitation could begin by 2015.化理想为现实,变荒野为坦途,困难和问题一定会接踵而来,但是,在人类的历史上,希望实现总是不可阻挡的。
