台湾海峡中、北部及邻近海域夏季浮游动物总生物量的分布特点

台湾海峡中、北部夏季浮游动物（非胶质）总生物量较丰富，1983年夏季的总生物量高于其他季节，1987年7、8月和1988年7月则高于1983年同期的生物量，这3a的高生物量分布区，一般都连片出现在上升流锋面区，显然和上升流的出现有密切关系。构成高生物量的优势种以外海广高盐种为主，生物量和高生物量区的分布态势都存在年际变化，这可能和不同性质水系的消长，相互推移及被囊动物的摄食竞争有关。     

锯缘青蟹胚胎发育过程主要生化组成

锯缘青蟹胚胎３种主要生化组成以蛋白质含量为最高，脂类含量次之，碳水化合物含量最低。胚胎发育的结果导致三种主要生化组成含量降低，其中蛋白质减少了３９．０％，脂类、碳水化合物含量分别减少了１７．０％、７．７％，说明蛋白是青蟹胚胎发育的主要能源物质，这可能与动物适应热带、亚热带的水生环境有关。

一种提高粘土矿物去除赤潮生物能力的新方法

在研究粘土颗粒与赤潮生物絮凝作用的基础上，建立了粘土表面改性对其絮凝作用影响的理论模型，认为改变粘土颗粒的表面性质提高其去除赤潮生物能力的主要途径，提出在粘土中引入ＰＡＣＳ（聚羟基氯化铝）的改性方法。结果表明，对于微型原甲藻（Ｐｒｏｒｏ－ｃｅｎｔｒｕｍ ｍｉｎｉｍｕｎ）体系，粘土中引入微量ＰＡＣＳ后，其去除率达９０％以上的高岭土用量由原来的２ｇ／Ｌ降至０．１ｇ／Ｌ，去除效率提高近２０倍。考察了ＰＡ     

灵山岛浅海岩礁区底栖生物的群落特点

浅海岩礁环境系高生产力区,在中、高纬度海域中,由大型海藻和大叶藻(Zosteramarina)所构成的初级生产力常为浮游植物初级生产力的数倍(Miller et al.,1971)。同时,此种环境又是以大型藻类或有机碎屑为食物的珍贵海产品鲍鱼(Haliotis)、刺参(Stichopus)、海胆(Strongylocentrotus)等的栖息场所和采捕作业区;还是一些优质鱼类星鳗( Astroconger myriaster)、鲈(Lateolobrax japonicus)等的藏匿场所和游钓渔业的渔场;重要经济藻类石花菜(Gelidium)等也在此环境中定着、生长。所以,浅海岩礁的资源开发前景很好。为了促进上述珍贵海产品的增、养殖生产和发展游钓渔业,有必要对浅海岩礁底栖生物群落的结构、功能进行系统研究,以便为岩礁区的资源开发和海岸带环境保护提供科学依据。为此,中科院海洋研究所在1987年初步调查的基础上,1992年以灵山岛为点,对水下岩礁环境和生物群落进行了系统的调查。本文主要分析浅海岩礁底栖生物的群落特点。     

Sublittoral meiofauna with particular reference to nematodes in the southern Yellow Sea, China

Densities of major meiofaunal taxa were investigated at 34 sampling stations during six cruises by R/V Beidou to the southern Yellow Sea, China from 2000 to 2004, and the community structure of free-living marine nematodes was studied during one of the cruises in 2003. Meiofauna abundance ranged from 487.4 to 1655.3 individuals per 10 cm². Nematodes and harpacticoid copepods were the two most dominant groups, contributing 73.8–92.8% and 3.5–18.7%, respectively, to the total meiofauna abundance. One-way ANOVA showed no significant annual fluctuation of meiofauna and nematode abundances from 2000 to 2004 in the southern Yellow Sea. However, two-way ANOVA based on six stations sampled in 4 years (2001–2004) showed that there were significant differences among the six stations and the 4 sampling years for meiofauna, nematode and copepod abundance. Correlation analysis demonstrated that meiofauna abundance was mainly linked to chloroplastic pigments. Other environmental factors could not be ruled out, however. A total of 232 free-living marine nematode species, belonging to 149 genera, 35 families and 4 orders, were identified. The dominant species in the sampling area were the following: Dorylaimopsis rabalaisi, Microlaimus sp.1, Prochromadorella sp., Promonohystera sp., Cobbia sp.1, Daptonema sp.1, Leptolaimus sp.1, Halalaimus sp.2, Aegialoalaimus sp., Chromadorita sp., Parodontophora marina, Parasphaerolaimus paradoxus, Quadricoma sp.1, Campylaimus sp.1, Halalaimus gracilis, Paramesacanthion sp.1, Paramonohystera sp.1, and Metalinhomoeus longiseta. CLUSTER and SIMPROF analyses revealed three main types of nematode community (or station groups) in the sampling area, including I: coastal community, II: transitory community between coastal and YSCWM (Yellow Sea Cold Water Mass), and III: YSCWM community. Each community was indicated by a number of dominant nematode species. Bio-Env correlation analysis between the nematode community and environmental variables showed that water depth, sediment water content, organic matter, chlorophyll a (Chl-a) and phaeophorbide a (Pha-a) were the most important factors to determine the community structure.     

The algorithms of chlorophyll-a concentration for CMODIS

The algorithms of extracting chlorophyll-a(Chl-a) concentration have been established for Chinese moderate resolution imaging spectrometer(CMODIS) mounted on Shenzhou-3 spaceship launched on 25 March 2002.The CMODIS is an ocean color sensor with 30 visible channels and 4 infrared channels,much different from other ocean color satellites and needs new algorithms to process data.Three models of Chl-a concentration were established based on Chl-a data retrieved from sea-viewing wide field-of-view sensor(SeaWiFS),with the average relative errors of 26.6%,24%.0% and 33.5%,respectively.This practical and economic approach can be used for developing the algorithms of Chinese ocean color and temperature sensor(COCTS) on the satellite Haiyang-1 to derive the Chl-a concentration concentration distribution.The applicability of the algorithms was analyzed using some in situ measurements.Suspended sediment is the main factor influencing the accuracy of the spectral ratio algorithms of Chl-a concentration.The algorithms are suitable to using in the regions where suspended sediment concentrations(SSC) are less than 5 g/m3 under the condition of relative error of Chl-a concentration retrieval within 35%.High concentration of suspended sediment leads to the overestimate remote sensing retrieval of concentration of Chl-a,while low-middle SSCs lead to the low Chl-a concentration values using the spectral ratio algorithms.Since the accuracy of Chl-a concentration by the spectral ratio algorithms is limited to waters of Case 2,it is necessary to develop semi-analytical models to improve the performance of satellite ocean color remote sensing in turbid coastal waters.
