新华社“雪龙”号８月４日电（记者 璩静）４日，中国第五次北极科考队在北纬７０度、东经３度的挪威海布放了中国首个极地大型海洋观测浮标，这也是中国首次将自主研发的浮标和观测技术推广到北极海域，并利用大型浮标对海气相互作用进行连续观测。

    The xinhua news agency“photo”Th August 4,（Reporter Qu static）4 days，China's fifth arctic expedition in 70 degrees north latitude、3 degrees east longitude of the Norwegian sea cloth the China's first polar ocean observation large buoy，This is the first time China will buoy and observation of the independent research and development of technology promotion to the arctic waters，And by using large buoy to air-sea interaction for continuous observation。

    在布放现场，几十位科考队员共同将重达１５吨、高１５米的大浮标经由船载吊车布放到海面，并通过连接于浮标底端的缆绳将各种获取数据的传感器固定在不同水深位置。“目前，国内外大浮标多数运行在浅海，布放深海大型浮标鲜有先例可循，尤其是在北极圈内布放大型浮标，要面临长达４个月的极夜无法利用太阳能、极区低温导致传感器冻结以及恶劣海况等特殊问题。”大浮标主要设计制造单位山东省科学院海洋仪器仪表研究所副研究员范秀涛说。

    In the cloth，Dozens of expedition to common will weigh 15 tons、15 meters high through the big buoy ship crane cloth to the ocean surface，And through the connecting at the bottom of the cable will buoy to get the data of sensors in different water depths fixed position。“At present，Big buoy most run at home and abroad in shallow water，Cloth deep sea large buoy few precedent，Especially in the arctic cloth large buoy，Face up to four months of very night cannot use of solar energy、Extremely low temperature sensor area to freeze and harsh, and other special sea conditions。”Big main design manufacturing unit buoy Marine instrument research institute of shandong academy of sciences (associate professor FanXiuTao said。

    目前，中国已全面掌握了大型浮标系统技术，包括浮标体结构技术，锚系技术，数据采集、存贮、传输技术等大批关键技术。据悉，这项由中国海洋大学、山东省科学院海洋仪器仪表研究所、国家海洋环境预报中心共同承担的海洋行业公益专项就采用了传感器防冻、传感器和采集通信系统双机运行、太阳能和风力双发电装置等特殊设计，以保障大浮标能在低温、极夜等极地条件下正常工作。

    At present，China has a comprehensive grasp of large buoy system technology，Including buoy body structure technology，Anchor department technology，Data acquisition、storage、Transmission technology, a large number of key technology。It is reported，The study by the China ocean university、Shandong academy of sciences Marine instrument research institute、National Marine environmental forecast to be the center of the public Marine industry special had adopted for sensor、Sensor and acquisition communication system dual machine operation、Solar and wind power generation, and other special design double device，In order to ensure the big buoy can in low temperature、A night and etc polar condition。

    研究表明，被称为“北极涛动核心区”的北欧海不仅是影响全球海洋循环和气候变化的重要海域，也是影响中国气候变化的关键海域，而缺乏该海域气象水文数据一直是中国气候预报的薄弱点。

    Research shows that，called“The arctic core out move”Nordic sea is not only influence global ocean circulation and climate change important waters，Also is the key to climate change affect China's territorial waters，And the lack of the sea is always the weather hydrological data weak spots in China's climate prediction。

    第五次北极科考队首席科学家马德毅表示，通过此次在关键海域布放大型海洋观测浮标，中国科学家可以实时获取海洋大气相互作用观测数据，全面了解北欧海在全球海洋循环和气候系统中的关键作用，并应用到气候预报模式中，对于大幅提高中国海洋监测能力、海洋与气候预测水平具有重要意义。此外，通过大浮标获取的数据还将与挪威相关科研机构共享，促进相关领域重大科学问题的解决。

    The fifth the arctic expedition's chief scientists MaDeYi said，Through this in key sea large Marine observation cloth buoy，Chinese scientists can capture the Marine atmosphere interaction observation data，To fully understand the Nordic sea in the global climate system in ocean circulation and the key role，And application to climate prediction mode，To increase China's Marine monitoring ability、Ocean and climate prediction level to have the important meaning。In addition，Through the big buoy data obtained by the will and Norway related research institutions sharing，Promote the major scientific fields related to the solution of the problem。

    据悉，全球现有６００余套锚碇浮标长期连续运行，最知名的要数美国位于赤道太平洋的浮标阵列和日本在赤道印度洋的浮标阵列，它们对监测和预报厄尔尼诺现象都发挥了核心作用。

    It is reported，The whole world has more than 600 sets of anchorage buoy long-term continuous operation，The most famous for the United States in the equatorial Pacific and Japan in the equator buoy array of the Indian Ocean buoy array，They to the monitoring and forecast of el nino phenomenon play a central role。
