南海晚第四纪浮游有孔虫类群变化所表征的古海洋学特征

通过对南海4个岩心的74个样品进行Q型因子分析,求得4个浮游有孔虫组合:亚热带-热带组合,温凉组合,热带易溶组合和亚热带组合。亚热带-热带组合为优势组合,它的发育状况反映了晚第四纪西太平洋热带海水对南海的影响程度,其因子载荷作为古海流特征的参数。温凉组合的发育与南海存在冷涡有关。利用转换函数FP-12E计算了南海南部表层古水温,冰期与间冰期的表层水温平均变化冬季为4.7℃和2.9℃,夏季为3.0℃和2.1℃,季节性温差冰期最大可达8.6℃,间冰期最大可达5.0℃,均比太平洋同一纬度海区的大。冬季表层古水温波动比夏季的大。全新世的表层水温呈上升趋势,但在NS86-43柱中有一变冷现象,这可能和the younger Younger Dryas有关。     

海洋细菌抑菌活性菌株的筛选

通过现场采水样和实验室模拟,研究珠江河口环境在一连串变化过程中,当各种浓度的Cu,zn,Pb,Cr和Cd单独存在或共存时,对单细胞藻类——硅藻和扁藻的毒性影响。     

气溶胶光学厚度的时空变化

在大气中气溶胶微粒是一种重要的大气微量成分。气溶胶光学厚度也是大气校正所需的重要大气参数，同时也是海洋水色卫星主要的数据产品。由于气溶胶光学厚度的时空变化较大，所以如何准确获取大气校正和卫星数据产品真实性检验所需的气溶胶光学厚度则是至关重要的。在简述气溶胶光学性质的基础上，并结合2002年6月HY—1南海实验数据来阐述现场气溶胶光学厚度的准确获取。     

Hydrocarbon Potential of Pre-cenozoic Strata in the North Yellow Sea Basin

The North Yellow Sea Basin ( NYSB ), which was developed on the basement of North China (Huabei) continental block, is a typical continental Mesozoic Cenozoic sedimentary basin in the sea area. Its Mesozoic basin is a residual basin, below which there is probably a larger Paleozoic sedimentary basin. The North Yellow Sea Basin comprises four sags and three uplifts. Of them, the eastern sag is a Mesozoic Cenozoic sedimentary sag in NYSB and has the biggest sediment thickness; the current Korean drilling wells are concentrated in the eastern sag. This sag is comparatively rich in oil and gas resources and thus has a relatively good petroleum prospect in the sea. The central sag has also accommodated thick Mesozoic-Cenozoic sediments. The latest research results show that there are three series of hydrocarbon source rocks in the North Yellow Sea Basin, namely, black shales of the Paleogene, Jurassic and Cretaceous. The principal hydrocarbon source rocks in NYSB are the Mesozoic black shale. According to the drilling data of Korea, the black shales of the Paleogene, Jurassic and Cretaceous have all come up to the standards of good and mature source rocks. The NYSB owns an intact system of oil generation, reservoir and capping rocks that can help hydrocarbon to form in the basin and thus it has the great potential of oil and gas. The vertical distribution of the hydrocarbon resources is mainly considered to be in the Cretaceous and then in the Jurassic.     

Iodine chemistry in deep anoxic basins and overlying waters of the Mediterranean Sea

Iodate (IO₃⁻) is the predominant dissolved species of iodine in the oxygenated waters of the Mediterranean Sea. Iodide (I⁻) is present in significant quantities (up to 65 nM) in oxygenated waters in the photic zone and near the interface above the anoxic and saline Bannock Basin. Lesser quantities of I⁻ (< 10 nM) are found throughout the rest of the oxic water column. An additional unidentified dissolved iodine species is present immediately above the anoxic interface.Total dissolved iodine (ΣI) increases dramatically across the seawater/brine interface. Part of this increase is undoubtedly the result of the dissolution of iodine-rich evaporites during formation of the brine bodies at the Tyro and Bannock Basins. The vertical distribution of ΣI and other dissolved chemical species (particularly PO₄³⁻) in the Bannock Basin brine, however, suggests an additional, present-day, diagenetic source of dissolved iodine to the brine. Based on the increase in the concentration of the most soluble major ions across the seawater/brine interface, 5–7 μM of the 11.5-μM increase in ΣI concentration must be attributed to diagenesis.

不同光照条件下海带体内各种化合物的含量及光合作用和呼吸作用的变化

实验检测了不同光照条件1200，600，01x下，海带体内多酚类化合物、可溶性糖、可溶性蛋白、叶绿素a、类胡萝卜素等的含量及其光合作用和呼吸作用的变化。实验结果表明，随着光照强度的减弱，海带体内多酚类化合物、可溶性糖、可溶性蛋白等的含量及其光合作用和呼吸作用均呈现下降的趋势，而叶绿素a和类胡萝卜素的含量则呈现出上升的趋势。     

红海湾水域溶解氧、pH值、盐度和营养盐分布特征及相互关系研究

通过１９９８年６月对广东省红海湾海水养殖水域环境因子的调查,阐述了海水中溶解氧、盐度、ｐＨ值和营养盐的分布特征及其变化规律,并讨论了它们之间的相互关系,结果表明,溶解氧及海水ｐＨ值随温度由北（除１５￣１７号站）向南（除６号站）增高而增高。同时证实了光合作用是导致溶解氧含量和ｐＨ值增高的主要原因。而营养盐与盐度呈密度的负相关,浮游植物总量随营养盐由北向南降低而明显增高。
