Comprehensive Analysis of the Relationship between Carbonate System Dynamics in Coral Reef and the Global Environmental Change.

1.为了监测珊瑚礁碳酸盐系统动态，在濑子岛站前安装了全自动总碱度-总碳分析系统。安装后，对系统进行了改进，以补偿白天辐射引起的温度升高和低潮时地下水迁移引起的盐度降低。根据不同的天气条件，粉质砂被泵送系统上涌，并沉积在蓄水池中。在濑子站有效地安装了网络摄像机，以监测该系统周围的环境状况。在日本化学学会西日本分支会议上介绍了初步结果（9月，冲绳）。全年每15分钟监测一次珊瑚礁海水中的PCO 2。获得每日海气CO2通量，并汇总为每月预算。2005年12月至2006年2月的CO2月收支显示了冬季（2005年12月至2006年2月）从空气到海洋的吸收和释放 ...更多信息 春、夏、秋三季（2006年3月至12月）。对珊瑚礁海水中PCO_2的周期性分析表明，其主要周期分别为13.66天、25.92小时、24.09小时和12.41小时，这与太阳和月亮的周期有关。此外，在8.19小时、6.21小时和6.10小时也有一些小周期，但没有被识别出来。2006年9月在德国柏林的哈恩-迈特纳研究所开展了中子层析成像的基础研究，以进行珊瑚代谢的现场观测。在不莱梅举行的ICRS欧洲会议（2006年9月）上介绍了对有机生产进行6年的长期监测。有害物质对珊瑚礁生态系统的化学影响问题已在Goldshirt会议（2006年6月，墨尔本）上提出。为了评价珊瑚礁初级生产力的潜力，对关成潟湖浅海竹富温泉周围珊瑚礁光合色素的分布进行了实地调查。这一重要结果表明，浅海温泉周围栖息着一种含叶绿素d的蓝藻Acaryochloris，它利用近红外光进行有效的产氧光合作用。含叶绿素d生物在海底的分布模式表明珊瑚礁生态系统具有高度的生物多样性，需要重新评估珊瑚礁和其他沿海海洋环境的初级生产力。少

1. In order to monitor the Carbonate System Dynamics of Coral Reef, fully-nutomated Total Alkalinity-Total Carbon Analysis System has been installed at the pior of Sesoko jima Station. After initial installation, the system was improved in order to compensate the temperature increase by irradiation at daytime and salinity decrease by ground water migration during low tide. Depend on the whether condition, the silty sands were upwelled by the punping system ant deposited in the water reservoir tank. Web Camera was effectively installed at Sesoko Station to monitor the Environmental Condition around the this System. Initial results were presented in the Meeting of West-Japan Branch of Chemical Society of Japan((Sept.at Okinawa).2. PCO2 in coral reef sea water was monitored at every 15 minutes through the whole year. Daily air-sea CO2 flux was obtained and summarized as monthly budgets. Monthly CO2 budgets shows absorption from air to sea during winter (from Dec.2005-Feb.2006) and release … More in spring, summer and autumn (from March to Dec, 2006).3. Periodicity Analysis of PCO2 in coral reef sea water showed that Major periodicities are 13.66 days, 25.92 hrs, 24.09 hrs and 12.41 hrs, which are dependent on solar and lunar cycles. Besides, some minor periodicities are seen in 8.19 hrs, 6.21 hrs and 6.10hrs, however they are not identified.4. In order of in site observation of coral metabolism, basic study of neutron tomography was carried out at Hahn-Meitner Institution in Berlin, German(Sept.2006). Long term monitoring of organic production for 6 years were presented in European Meeting of ICRS at Bremen(Sept.2006). Chemical impact of hazardous substances in coral reef ecosystem was presented in Goldshmidt Conference (June.2006 at Melbourne).5. In order to evaluate the potential ability of primary production of coral reef, field survey on the distribution of of photosynthetic pigments was performed around the shallow sea Taketomi-hot spring in coral reef of Sekisei-lagoon. The important result shows that chlorophyll-d containing cyano-bacteria Acaryochloris is habitat around the shallow sea hot spring, which utilizes the near-infrared light and performs oxygen generating photosynthesis effectively. Mode of distribution of chlorophyll-d containing organism in the bottom sea suggests the high bio-diversity of coral reef ecosystem and requires the re-evaluation of primary production of coral reefs and other coastal marine environments..
