The three-layer model of the thermohaline structure in the shallow seas
Yang Dianrong
1993, (3): 323-334.
Abstract:
A three-layer model of the thermohaline structure is developed on the basis of the two-layer model of thermocline.The model is able to simulate the depth,thickness and intensity of both thermocline and halocline, and the temperature and salinity of b...
Study on short-range numerical forecasting of ocean current in the East China Sea——Ⅰ Basic problems of ocean current forecasting and structure of the models
Zhao Jinping, Chen Zhongyong, Shi Maochong
1993, (3): 335-345.
Abstract:
Ocean current forecasting is still in explorative stage of study.In the study, we face some problems that have not been met before.The solving of these problems has become fundamental premise for realizing the ocean current forecasting.In the present...
Numerical simulation of fluctuation and undulation of the thermo-cline under tide (tidal current) action in the Bohai Sea
Zhang Yanting, Wang Yijiao
1993, (3): 347-357.
Abstract:
Besides seasonal variation, instantaneous variation of thermal layer will occur under the effects of tide, tidal current and wind disturbance.In this study the numerical simulation has been first carried out on fluctuation and undulation of thermal l...
Marine Meteorology
Climatological characteristics of monsoons and tropical cyclone activities over China seas and their influences on hydrological and seasonal structures over the South China Sea
Chen Shangji
1993, (3): 359-377.
Abstract:
The aim of this paper is to study whether the features of perennial summer over the South China Sea remain constant all the year round or not, and whether there are any seasonal differences throughout the year or not.According to the characteristics ...
A study on dynamical features of air-sea coupling waves in the tropics
Yang Xiuqun, Huang Shisong
1993, (3): 379-393.
Abstract:
The dynamical features of air-sea coupling waves and their stabilities in a simple coupled air-sea model in the tropics have been studied with respect to interaction occurring among different types of the free waves in the ocean and in the atmosphere...
The numerical simulation of Pacific Ocean circulation with five-level model
Xing Runan, Chao Jiping
1993, (3): 395-404.
Abstract:
A five-level oceanic primitive equation model has been developed.This model is integrated numerically with annual mean wind stress and heat flux at sea surface for 30 a.The ocean circulations tend to quasi-stability.The simulated results show that th...

Zonal discrepancy of iodine in the West Pacific Ocean and its adjacent seas
Cheng Xianhao, Yu Guohui, Zhang Ping
1993, (3): 405-415.
Abstract:
The species of iodine in the water samples collected from the west Pacific Ocean and its adjacent seas were analysed.Results show that the concentration of total inorganic iodine appears higher in the south than that in the north of the Equator.The i...
Gas chromatographic determination of lignin in sediment
Fu Tianbao, Chen Song, Jiang Shanchun
1993, (3): 417-423.
Abstract:
After the oxidation of river and marine sediments with CuO under alkaline conditions, the phenolic compounds in the oxidation products are determined gas chromatographically and compared to that of lignin oxidation products.The method of CuO oxidatio...
Marine Geology and Geomorphology
A note on crustal structure between Antarctic Peninsula and East Antarctic craton across the shelf of southern Weddell Sea
Liu Jianhua
1993, (3): 425-429.
Abstract:
Analysis of gravity data based on the Airy isostasy, magnetic depth estimates and few seismic refraction data taken together indicates a thinning of the crust between the Antarctic Peninsula and the East Antarctic craton below the Filchner and Ronne ...
Foraminifera in stratigraphy and paleoenvironment
Chen Ronghua
1993, (3): 431-443.
Abstract:
Through the analysis of foraminiferal fossils in the cores and the combination with the data of paleomag-netism and 1C ages, seven transgressive strata are recognized in the plains of coastal areas of Zhejiang Province.Among them the upper five ones ...

Distribution of planktonic copepods in the Kuroshio area of the East Chine Sea to the southwest of Kyushu in Japan
Lin Yuhui, Yasuaki Nakamura
1993, (3): 445-456.
Abstract:
The materials were obtained from the survey conducted in the Kuroshio area of the East China Sea to the Southwest of Kyushu in Japan (29°30'-32°00', 128°00'-130°00'E) on board the R.V.Yoko Maru of Seikai Regional Fisheries Lab, Fisheries Agency, Japa...
The study of fluorescence characteristics and biochemical composition of a marine diatom Thalassiosira pseudonana 3H in light and dark cycles-Ⅱ. The effects of light
Yang Xiaolong, Zhu Mingyuan, J. J. Cullen
1993, (3): 457-464.
Abstract:
The effects of light on the fluorescence characteristics and biochemical composition of a marine diatom Tha-lassiosira pseudonana in light and dark cycles were investigated with semi-continuous culture.The results indicate that, with the increase of ...
The joint long-term distribution of design environmental factors for offshore structures Multivariate probabilities and simulating method
Shi Jiangang, Liu Defu, Wang Zheng
1993, (3): 465-474.
Abstract:
With the development of ocean engineering, it is one of the most important factors which determine the structural safety, cost and suitable forms of engineerings to select the ocean environmental design criteria.Owing to the complexity, variation and...
