Three-D numerical simulation of wind-driven current and density current in the Beibu Gulf
Xia Huayong, Li Shuhua, Shi Maochong
2001, (4): 455-472.
Abstract:
The Casulli's difference scheme was introduced into the three-dimensional ocean model in the present paper, and the wind-driven current and thermohaline current were simulated. The results show that, southwesterly monsoon in summer induces a clockwis...

Test of numerical prediction of sea water temperature in the Taiwan Strait
Wang Xiuqin, Huang Huowang, Deng Jian, Qian Chengchun
2001, (4): 473-481.
Abstract:
A dynamic numerical prediction model of sea water temperature for limited sea area is used to predict the sea water temperature at the sea area near Fujian. Essential adjustments have been made in accordance with the characteristics of this region. T...
A numerical storm surge forecast model with Kalman filter
Yu Fujiang, Zhang Zhanhai, Lin Yihua
2001, (4): 483-492.
Abstract:
Kalman filter data assimilation technique is incorporated into a standard two-dimensional linear storm surge model. Imperfect model equation and imperfect meteorological forcimg are accounted for by adding noise terms to the momentum equations. The d...

Modelling nitrogen and phosphorus cycles and dissolved oxygen in the Zhujiang Estuary Ⅰ. Model development
Guan Weibing, Wong Lai-Ah, Xu Dongfeng
2001, (4): 493-504.
Abstract:
An ecosystem-based water quality model was designed to estimate the biochemical reaction of nutrient and dissolved oxygen in conjunction with a three-dimensional hydrodynamic and sediment model. As both phosphorus and nitrogen successively limit phyt...
Modelling nitrogen and phosphorus cycles and dissolved oxygen in the Zhujiang Estuary Ⅱ. Model results
Guan Weibing, Wong Lai-Ah, Xu Dongfeng
2001, (4): 505-514.
Abstract:
In the present study, the ecosystem-based water quality model was applied to the Pearl River (Zhujiang) Estuary. The model results successfully represent the distribution trend of nutrients and dissolved oxygen both in the horizontal and vertical pla...
Dissolved Cu, Pb, Zn and Cd in the South China Sea surface waters
Huo Wenmian, Ji Weidong, Xu Kuncan
2001, (4): 515-522.
Abstract:
A total of 106 surface water samples were collected in the South China Sea during two transects in June and December 1998. The samples were collected with strictly contamination free procedure and trace metals were measured by clean laboratory method...
Nutrient profiles in interstitial water and flux in water-sediment interface of the Zhujiang Estuary of China in summer
Pan Jianming, Zhou Huaiyang, Liu Xiaoya, Hu Chuanyu, Deng Lixian, Zhang Mei
2001, (4): 523-533.
Abstract:
The profiles of nutrient salts in the interstitial water of sediment were analyzed in the Zhujiang Estuary in the summer of 1999, and based on the profiles of content and characteristic of nutrients, the relationship between nutrients in the intersti...
Composition index of n-alkanes and paleoenvironmental study in sediments of the Arctic
Lu Bing, Zhou Huaiyang, Wang Zipan, Lu Douding
2001, (4): 535-551.
Abstract:
This paper reports different concentration patterns of n-alkanes distribution in the sediments from the Chukchi Sea, the Bering Sea in the Arctic. Factor statistical analysis method is used for studying the source of n-alkanes and paleoenviroment. Th...

Geochemical characteristics of sediments from the COMRA registered pioneer area (CRPA), equatorial northeastern Pacific Ocean
Ni Jianyu, Zhou Huaiyang, Pan Jianming, Zhao Hongqiao, Hu Chuanyu, Wang Fangguo
2001, (4): 553-561.
Abstract:
COMRA (China Ocean Mineral Resources Association) registered pioneer area (CRPA) is located in the western part of the area between the Clarion and Clipperton Fraction Zones (CCFZs).Based on distinctive color and bio-disturbing properties, two layers...

Wu Xinzhong, Li Dengfeng, Pan Jinpei
2001, (4): 563-574.
Abstract:
The epidemiological investigations on the disease and death in mature eggs, embryonic developmental periods and larvae populations[including oocytes, fertilized ovum, early embryonic phase larvae (6 h), D-shaped phase larvae (24 h), early umbo phase ...
A fuzzy distinguishability on species composition similarities of pelagic fishes in different years in the southern Taiwan Strait
Zhang Chengmao, Fang Shuimei, Yang Shengyun
2001, (4): 575-583.
Abstract:
A fuzzy mathematical method is used to discriminate the similarities of pelagic fishes landed in the 9180 hauls by 10 light-seine information yessels in the southern Fujian waters from 1989 to 1998. The results indicate that the dominant species of t...
Effect of estradiol-17β on pituitary-thyroidal axis of Japanese eel (Anguilla japonica)
Qu Xiancheng, Masaki Nagae, Sinji Adachi, Kohei Yamauchi
2001, (4): 585-596.
Abstract:
The effect of estradiol-17β (E2)treatment on the pituitary-thyroidal axis has been investigated in female Japanese eels in seawater. The eels were injected with 1 mg/kg body weight (BW)weekly for two to eight weeks; another group was treated with 5 m...

Vertical variations of wave-induced radiation stress tensor
Zheng Jinhai, Yan Yixin
2001, (4): 597-605.
Abstract:
The distributions of the wave-induced radiation stress tensor over depth are studied by using the linear wave theory, which are divided into three regions, i.e., above the mean water level, below the wave trough level, and between these two levels. T...
