氮磷营养盐与有机汞联合作用对微氏海链藻生长的影响

探讨在高营养盐（氮、磷、硅分别为浮游植物生长的营养盐阚值≥40、50、9倍）条件下，氮浓度及氮磷摩尔比值[n（N）／n（P）]变化、汞（甲基汞和乙基汞）对微氏海链藻（Thalassiosira weissflogii）生长的影响。结果表明，高营养盐区海链藻的生长遵循营养盐限制的唯一因子论；氮浓度和氮磷比提高促进生长，当n（N）／n（P）=64则呈抑制效应；生长初期，甲基汞和乙基汞均产生毒性抑制作用，生长中后期，适量甲基汞（浓度≤1．0μg／L）、乙基汞（浓度≤0．5μg／L）却呈兴奋效应，促进生长；汞形态不同，剂量-效应关系不同。氮和有机汞是海链藻生长的刺激因子。适度有机汞污染与氮富营养化对微氏海链藻的生长产生协同效应。     

THE DIAGNOSTIC CALCULATION OF EQUATORIAL FLOWS IN THE EASTERN PART OF THE WESTERN PACIFIC OCEAN

On the basis of observational data of the eastern part of the West Pacific Ocean, a diagnostic calculation of equatorial flow for this region is performed by using the authors' model equations and computing scheme and methods. For the first cruise (January 3-March 4, 1979), the results show: (i) The primary driving force of the equatorial surface flows comes from the prevailing northeasterly wind field, with an average uniform wind speed Vw = 6.3 m/s. The steady westward wind produces divergent westward flows in the surface layers, causing an upwelling near the equator. The importance of the steady wind stress in the upper layer (120 m) decreases with depth and becomes insignificant at the level of z = 75 m or z = 100 m, (ii) The equatorial undercurrent is a strong eastward and equator-ward flow, with its eastward component of undercurrent larger than its meridional component. The core of the undercurrent is at the thermocline, and its maximum velocity is 88-90 cm/s at the level of z=200 m. The deeper f     

VARIATIONS OF THE SUMMER MONSOON IN THE SOUTH CHINA SEA

In this paper we investigated the variations of summer montoon in the South China Sea. We found that there are two kinds of oscillations in the intensity of the monsoon, one has a period of forty days, the other, fourteen days. We also found that the oscillation of a period of forty days is caused by the alternative extension of the monsoon trough eastward in the South China Sea and the extension of the subtropical anticyclone westward in the West Pacific.It is our opinion that the summer monsoon in the West Pacific and the South China Sea is a system which is independent - of the Indian monsoon and that the dividing line between these two monsoon systems is at the longitude 100°E.

Mesoscale eddies in the South China Sea and their impact on temperature profiles

Some life history statistics of the mesoscale eddies of the South China Sea (SCS) derived from altimetry data will be further discussed according their different formation periods.A total of three ATLAS (autonomous temperature line acquisition system)mooring buoys data will be analyzed to discuss eddies‘ impact on temperature profiles.They identify that the intraseasonal variation of SCS thermocline is partly controlled by mesoscale eddies.

生物胺对锯缘青蟹大颚器发育的调节作用

雌性锯缘青蟹(Scylla serrata)于实验的第1天、第5天、第10天，分别注射100μL剂量为1μg／g体质量的5-HT，OA和DA，第15天解剖。结果表明，5-HT对锯缘青蟹大颚器发育具有显的促进作用，OA和DA的作用不明显。经免疫细胞化学检测，大颚器内存在5-HT免疫阳性细胞，免疫阳性细胞多数为卵圆形，少数具有很长的胞突，该结果首次为5-HT参与大颚器的生理活动提供了形态学证据。     

蛋白质组学的研究概况及其在海洋生物学中的应用

随着DNA序列测定技术的飞速发展，人们可以在很短的时间内获得某种生物基因组的全序列。生物体的生命活动主要依赖于基因组的产物——蛋白质组，但是蛋白质组的研究相对于基因组来说却要复杂得多。蛋白质组技术是在细胞内整体蛋白质水平上进行研究，从蛋白质整体活动的角度来研究生命活动的规律。综述了蛋白质组和蛋白质组学出现的背景、起源、概念、研究技术、研究内容、面对的挑战、开展该项研究的意义、陆生动植物和微生物蛋白质组学的研究进展及海洋生物蛋白质组学的研究概况。目前，普通生物方面的蛋白质组工作开展得较多，海洋生物方面却相对滞后。种种迹象表明，开展海洋生物蛋白质组学研究，对揭示生命的奥秘、促进海洋资源的开发都有重大的推动作用。
