渤海、黄海、东海水温垂直结构统计特征分析

渤海、黄海与东海的水温垂直结构呈现陆架浅海特有的水文特征，其分布与变化甚为复杂。几十年来，虽然中外海洋学家曾对这些海区水文要素的分布及其变异作过大量研究，但是，关于水温垂直结构各特征值较系统的分析研究则始于六十年代初期，毛汉礼等根据一年观测资料(1958-1959)作了较全面的阐述。但是这些资料多数是用颠倒温度表观测，少数为深度温度计(BT)观测；并且研究海区限千124°E以西。本文试图分析研究近年来渤海、黄海与东海水温垂直结构各特征值的统计特性；研究海区有了较大的扩展：黄海至124°30''E；东海至127°E。 文中引用国家海洋局1975一1980年间BT观测资料，共计166个观测站，累积约七千余个BT片资料。     

平均海平面若干问题的研究

海面是不静止的,时刻在运动着.在解决实际问题时,一般采用平均海平面.平均海平面是以自记验潮仪(或水尺)进行长期观测而计算得到的,通常是取观测记录每整小时潮高的平均值,称为该观测时期的平均海平面.平均海平面是作为计算陆地高度的起算面,也就是山高的基准面.海图深度基准面也是依赖于平均海平面算出的.由于海面受天文、气象、海洋因素等影响,真实的平均海平面不易求出,但我们可应用多年的平均海平面逼近它.

海洋生物-光学算法研究──南黄海叶绿素浓度的估算

根据１９９５年９月中日合作南黄海现场观测资料，对南黄海生物－光学算法进行研究。首先对南黄海现场多光谱反射比数据进行因子分析，解反射比协方差矩阵的特征问题；解出特征值和对应的特征向量，求出主因子，然后建立叶绿素α对主因子的多元线性回归方程，并对算法进行回报和预报检验。计算结果表明，该算法具有较高精度，同时也显示出天气条件对估算精度产生较大影响。

Interfacial geochemistry of barium in suspension and sediment from Zhujiang Estuary

Chemical forms of Ba are determined in samples of suspension and sediment from the Zhujiang Estuary. Their interfacial geochemical processes are discussed. Total suspended Ba content is between 2. 4 and 40. 4 μg/L, and mostly exists in the crystalline form (43. 5%), secondly in the Fe-Mn oxidative form (23.1%). Percentages of organic, carbonate and exchangeable forms are 14. 8%, 11. l%and 7.4%, respectively. Total content of Ba in the sediment is between 158. 6 and 48. 0 ug/g. Percentages of crystalline form, Fe-Mn oxidative form and carbonate form are 78. 4% ,13. 5%and 8. 2%, respectively. Organic and exchangeable forms are not detected. The study on the mechanism of interfacial movement suggests that the salinity range of 10 is the turning point for the varied distribution of Ba. The subsidence of crystalline form affects the decrease of Ba content in suspension. The decrease mostly takes place in the salinity range lower than 10, which corresponds to the high value of Ba content in the sediment. The     

Current status of bacteriological parameters and DOC/POC in Xiamen coastal waters

The surface and bottom waters samples were collected from six locations in Xiamen western sea. The quantified estimation of bacterial production (3H-thymidine method) and observation of bacterial heterotrophic activity (14C-glucose method) have been made in order to have a better understanding of the role of marine bacteria and their activities. The results showed that the mean value of bacterial heterotrophic activity was 9×108 cells/(L.h) in the surface waters and 2.6×108 cells/(L.h) in the bottom waters. The mean value of bacterial production was 38×108 cells/(L.h) in the surface waters and 7.1×108 cells/(L.h) in the bottom waters. The relationship between bacterial production, heterotrophic activity, POC and DOC measured during this survey were discussed. The good understanding of the relationship between bacteria activity and total coliform was addressed.
