深圳湾福田潮滩重金属含量及对大型底栖动物的影响

根据2002年1月和10月在深圳湾福田潮滩同时获得的大型底栖动物和重金属数据进行分析表明，深圳湾福田潮滩Cu、Pb、Zn、Cd含量明显超标．2002年10月Pb、Cd、Cu、Zn含量的平均值比2002年1月高．与历史资料对比，近几年Cu含量有增加趋势．2002年1月，深圳湾福田潮滩奇异稚齿虫密度与沉积物中Pb、Cd、Cu、Zn含量均有显著负相关关系．尖刺缨虫密度与Pb、Cd、Zn含量均有显著负相关关系，与Cu的相关系数也接近显著相关临界值．2002年10月，只有小头虫密度与Cd有显著正相关关系．文中分析了影响重金属与大型底栖动物数量关系的环境因素．

Ocean bottom tiltmeter with acoustic data retrieval system implanted by a submersible

Sensitive Ocean Bottom Implanted Tiltmeters (OBITs) with a sophisticated data retrieval system have been developed in order to observe directly the subduction of oceanic lithosphere. The OBIT is the first long-term geophysical instrument which was designed to be deployed by a manned deep-sea submersible. When the OBIT is put on oceanic lithosphere which is bending and is about to subduct under a deep sea trench, the OBIT records the subduction by observing the tilt of the surface of the lithosphere. The OBIT system has a sensitivity of 10^-8 radian, which is enough to detect the ongoing subduction in months or years. The OBIT may give an answer to the question whether there are fluctuations in the subduction rate.Two OBITs were successfully deployed on a seaward slope of the Kuril Trench by the newly built French deep submersible, Nautile. The OBITs were installed on the northwest shoulder of Erimo seamount, at a depth of 3930 m, in the Kuril Trench. In order to attain stable long-term observations of crustal deformations, the sensing unit was cemented onto bare rock by mortar. We have not yet had an opportunity to recover the data.The life of the instruments is expected to be more than five years. An acoustic data transmission system has been developed for the OBIT data recovery. The stored data can be retrieved at any moment during the observation period, with no need to retrieve the instruments nor to interrupt the observation, by use of the acoustic system. The acoustic system has a high data transmission rate as well as extremely low power consumption. This will be the first long-term crustal deformation measurement on the sea floor.

福建漳州海域麻痹性贝毒的污染状况调查

本文通过对漳州海域的养殖区栉孔扇贝扣僧帽牡蛎为期1a的麻痹性毒素（PSP）污染状况的调查分析，以了解贝类海产品的安全性．贝毒测定按照AOAC小白鼠法进行，利用高效液相色谱（HPLC）进行贝毒成分分析．结果表明：漳州海域的栉孔扇贝为该海域轻微PSP染毒贝类，含量为1．83～3．23MU／g；漳浦古雷和东山铜陵的栉孔扇贝样品检出率分别为66．7％和16．7％．高效液相色谱分析表明，样品中PSP成分为B1、GTX1／4、GTX2／3及STX和C毒素．漳州海域贝类PSP含量很低，未超出安全食用标准；但毒素分布存在季节差异，春季检出率较高．因此有针对性的加强贝毒监测非常必要．
