The seafloor observation system is becoming an important infrastructure for marine research because it is transforming oceanic research from temporal investigation to long term observation.The East China Sea coastal seafloor observatory,located between 30°31′44″N,122°15′12″E and 30°31′34″N,122°14′40″E,is constructed near the Xiaoqushan Island outside the Hangzhou Bay on the inner continental shelf of the East China Sea.The observatory is connected by a submarine optical fiber composite power cable that is more than one kilometer long and consists of a special junction box that transmits power and communication signals to different instruments.The special junction box has a variety of waterproof plugs and connects to three different instruments installed in a trawl preventer.The submarine optical fiber composite power cable is landed on the platform by The East China Sea Branch,State Oceanic Administration and the power is continuously supplied by the solar panels and solar battery on the top of the platform.The real time data are directly sent through the cable to the platform and are transmitted by CDMA wireless to the receiver at the State Key Laboratory of Marine Geology of Tongji University.Measurements at the observatory have been taken since April 20,2009 after installation and the results have been interpreted.The characteristics of the near bottom boundary are constrained by a sediment suspension model using portion of the observed data.In particular,discussion is provided on the sea surface height anomaly at Xiaoqushan Island influenced by the tsunami driven by the 2010 Earthquake in Chile.The successful establishment of the coastal seafloor observatory is the first step toward future development of seafloor observation systems in China.It not only accumulates experiences in technology and engineering,but also paves the way for performing important oceanic research using the long term continuous observation platform. 相似文献

语言是文化的载体。语言的文化性充分表现在它的文化的载蓄、映射功能中。澳洲文化集多元文化之大成,广泛吸纳了风格迥异的不同文化传统。不同文化形态之间相互渗透、兼容、揉合必然会在语言中有所反映。作为澳洲文化容器的澳英词汇反映了澳洲五彩斑斓的多元文化。 相似文献

根据已知的中国古代观象台方位,对金代司天台位置进行初次探讨.认为:第一,按照东汉灵台的位王推测,应住于金皇宫的南面即南郊;第二,按金中都皇城宫城复原示困中拜天台的方位推断应在皇城东南方向;第三,按元明清观星台的位置类推金司天台方位应在现在的丰台区右安门外东南一带.另外,从明朝建的天坛是位于皇城的东南方向;明朝建的日坛是位于宫城偏东南方向. 相似文献
