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，在小子岛站前安装了全自动全碱度-全碳分析系统。初始安装后，对系统进行了改进，以补偿白天照射引起的温度升高和低潮时地下水迁移引起的盐度降低。根据条件的不同，粉砂被泵送系统上涌并沉积在蓄水池中。网络摄像头被有效地安装在Sesoko站，以监测该系统周围的环境状况。初步结果在日本化学会西日本分会会议上发表。在冲绳)。2。全年每15分钟监测一次珊瑚礁海水的二氧化碳分压。每日的海气CO2通量得到并汇总为每月预算。每月二氧化碳预算显示冬季（2005年12月至2005年2月）从空气到海洋的吸收量。2 .春、夏、秋（2006年3月至12月）更多上映。珊瑚礁海水PCO2的周期分析表明，主要周期分别为13.66 d、25.92 h、24.09 h和12.41 h，主要依赖于太阳周期和月亮周期。此外，在8.19、6.21和6.10时出现了一些小的周期性，但没有被识别出来。为了对珊瑚代谢进行现场观测，在德国柏林的Hahn-Meitner研究所进行了中子层摄影的基础研究（2006年9月）。2006年9月在不来梅举行的ICRS欧洲会议上提出了6年的有机生产长期监测。有害物质对珊瑚礁生态系统的化学影响在2006年6月墨尔本Goldshmidt会议上发表。为了评价珊瑚礁的潜在初级生产能力，对关成礁湖浅海竹富温泉周围的珊瑚礁进行了光合色素分布的野外调查。这一重要结果表明，含叶绿素-d的蓝藻Acaryochloris是浅海温泉周围的栖息地，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，需要对珊瑚礁和其他沿海海洋环境的初级生产进行重新评价。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..
