福建漳浦前湖湾有孔虫群落及其沉积环境

对福建漳浦前湖湾潮间带两个钻孔岩心和表层沉积物中的有孔虫进行分析研究,有孔虫出现在钻孔最上部厚约2.46-2.96m的砂层中.根据群落优势种生态和非种特征判断,该段各样品有孔虫沉积环境均为近岸浅水环境,尽管其间海面有过3次上下波动变化.根据地层关系判断,其当为现代的产物.     

超短基线声学定位原理及其应用

声学定位系统（Acoustic Positioning System)的技术研究和应用开发在现代海洋科学调查中起着重要作用。以挪威Simrad公司的HPR410P超短基线定位系统为例，从几方面讨论了超短基线（Ultrashort Baseline)声学定位系统的原理、应用范围、定位误差来源及其相应的修正方法；通过最大程度地减少误差来提高系统的定位精度，从而获取高质量的海洋科研调查资料。     

日本沼虾黑鳃病几种同工酶的变化与病理分析

酯酶（EST），过氧化物酶（POD），乳酸脱氢酶（LDH）和苹果酸脱氢酶（MDH）同工酶在日本沼虾中存在着组织和器官的特异性，患黑鳃病后酶带发生显著变化。在肌肉、肝脏、心脏和鳃中病虾较健康虾的LDH酶谱分别缺失了2、6、2和1条酶带，同时肝脏中新增了1条酶带；POD酶谱分别缺失了0、7、4和2酶带，肌肉中新增了2条酶带；EST酶谱分别缺失了0、2、3和1条酶带，肌肉、心脏和鳃中分别新增了1、2和2条酶带；MDH酶谱分别缺失了0、2、1和1条酶带，肌肉和脏脏中各新增了1条酶带。     

Wave-Current Forces on Small Square Cylinders (Part I)

-Based on the extended Morison Equation and model tests, the in-line forces on small square cylinders caused by waves (regular and irregular) and currents are analyzed in detail in this paper. The hydrodynamic coefficient CD and Cu related to KC number and the effect of direction of wave incidence are also given, which can be used in engineering practice.     

闽南：台湾浅滩渔场变性水团的初步分析

根据聚类方法，对闽南－台湾浅滩渔场变性水团进行划分，本海区共有６个变性水团。讨论各个变性水团在不同季节消长变化规律。     

A study on zooplankton distribution patterns and indicator species in Kuroshio upstream area and adjacent East China Sea

On the basis of the data of zooplankton biomass and three major taxa—— Copepoda, Chaetognatha andSiphonophora of May-June 1986, July-August and December 1987, the distributional patterns and the indicator species of zooplankton in the Kuroshio and adjacent waters of the East China Sea are preliminarily studied. The results are as follows:The horizontal distribution of zooplankton biomass and the abundance of copepods, chaetognaths and siphonophores arecurred in the continent area northwest of Taiwan and the south-centre section of the East China Sea continent, which are the mix front of different waters. Zooplankton in the water area inside of Ryukyu Islands presented low abundance and high diversity. There are clear seasonal variations in zooplankton biomass and abundance in the study area. The strength or weakness of different water masses and fronts is the basic reason for the variations of zooplankton biomass and abundance.The species composition of zooplankton in the study area is complex and var     

AN ECOLOGICAL STUDY OF BENTHIC ORGANISMS IN THE NEARSHORE WATERS TO THE WEST OF TAIWAN STRAIT

In seven cruises on benthic organisms in the nearshore waters(>50 m) to the west of the Taiwan Strait(23°20''-25°54''N,117°11''-119°58''E) in 1961-1964,altogether 189 stations of quantitative grabbing and 33 stations of qualitative trawling were made.
Altogether 392 species of benthic organisms have been identified.The composition was dominated by nearshore shallow water species,with tropical and subtropical species absolutely dominant.The total average of biomass was 38.0 g/m² and average density,116.0 ind./m².The communities of benthic organisms in the area can be classified into five communities namely,(1) Amphiura sp.-Acaudina molpadioides Community;(2) Protankyra asymmetrica-Arnphioplus pracstans-Murex trapa Community;(3) Modiolus meicalfei-Phyllophorus liuwutiensis-Armandia letocirris-Nephtys sinensis Community;(4) Branchiostoma belcheri-Solenr oseomaculatus-Marphysa sinensis- Onuphis eremita Community;(5) Iconomtra japonica-Barbatia decussata Community.     

东海南海交接带重磁场特征及新生代盆地成因

东海南海构造交接带及其邻近海区(简称交接带)位于中国东部大陆边缘,东邻俯冲板块边界。台湾以北是琉球海沟俯冲带,台湾以南为马尼拉海沟俯冲构造带。区域重磁资料分析结果表明,该东海陆架区存在3条重力高和2条重力低,重力高分别对应于闽浙隆起带、渔山低凸起和陆架外缘隆起,最大值高达50×10-5m·s-2;重力低对应于沉积盆地,最低值在台西南盆地,约为-20×10-5m·s-2。重磁特征表明东海盆地外缘台湾 钓鱼岛构造带具有明显的自由空间异常,磁场为平缓负异常,由古近系、白垩系或更老的变质岩及中新世的侵入岩组成,向南延伸至澎湖隆起。因为澎湖隆起具有高重力异常,放射性年龄表明这些碱性玄武岩形成于17 8～8MaBP,其特征同现在的琉球岛弧一样,可能是残留的古琉球岛弧。台西南盆地南侧(上陆坡)的凸起具有类似的幅度异常,呈ENE—WSW向,并消失在台西南盆地南段。新生代以来,盆地张裂活动具有不同时性,并向陆架边缘变得年轻。东海大陆边缘盆地属弧后残留盆地成因,多因岛弧的迁移而新生,但珠江口盆地则是被动大陆边缘裂陷作用所致。
