1) Deep seawater in the Suruga Bay is pumped up from 397m-depth and 687m-depth with 24m-depth of surface layer water. The main purpose of this study is to understand the controlling factors of ecosystem dynamics at Suruga Bay from surface to deep layers and also to characterize organic matters produced by biological processes. Seasonal studies at the field and mesocosms experiments have been carried out during three years. A well-developed ecosystem in both 400m depths and 700m-depth seawater was developed, with including members of grazing food web and a sufficient microbial loop for the re-mineralization of organic mattes. The amount of fixed organic matter during 11 days of incubation was near 60 times and 100 times for 400m depths and 700m depths respectively. The response of deep-sea water from both depths is different in terms of time scale (rapid in case of 700m than that of 400m) and species composition.2) The measurement of radiocarbon showed that age of deep seawater in the Suruga bay ranges from 400 years for 400m and 1000 years for 1000m-depth. Organic matters were characterized as amino acids, phospholipids, carbohydrate, and most of organic matters of molecular weight is below 1000 daltons (90%).

1)骏河湾的深层海水从397m深度和687m深度抽取，表层水深度为24m。本研究的主要目的是了解骏河湾从表层到深层生态系统动态的控制因素，并表征生物过程产生的有机物。在三年期间进行了实地季节性研究和围隔实验。在400 m和700 m深度的海水中发育了一个发育良好的生态系统，包括放牧食物网成员和足够的微生物循环，用于有机物质的再矿化。在11天的培养过程中，固定有机质的量分别是400m和700m深度的近60倍和100倍。2）放射性碳的测定结果表明，骏河湾深层海水的年龄在400m处为400年，在1000m处为1000年。有机质主要由氨基酸、磷脂、碳水化合物组成，分子量在1000道尔顿以下的有机质占90%。
