A three-dimensional numerical calculation of the wind-driven thermohaline and tide-induced Lagrangian residual current in the Bohai Sea
Wang Hui, Su Zhiqing, Feng Shizuo, Sun Wenxin
1993, (2): 169-182.
Abstract:
On the basis of a three-dimensional weakly nonliear theory of Lagrangian residual current in the Baroclinic shallow seas, a diagnostic numerical calculation of wind-driven, thermohaline and tide-induced Lagrangian residual current in the Bohai Sea is...
On low-pass digital filters in oceanography
Wang Jia, Ralph T. Cheng
1993, (2): 183-196.
Abstract:
Two types of filters are widely used to remove semidirunal and diurnal tidal signals and other high frequency noises in oceanography. The first type of filters uses moving average with weights in time domain, and can be easily operated. Some data wil...
Marine Physics
A study on remote sensing models of sea ice thickness by microwave radiometry
Zheng Quan'an, Zhang Dong, Pan Jiayi
1993, (2): 197-206.
Abstract:
Extrapolating from the propagation theories of electromagnetic waves in a layered medium, a three-layer medium model is deduced in this paper by using microwave radiometric remote sensing technology which is suitable to first-year sea ice condition o...
Marine Meteorology
East-west oscillation of sea temperature in the Equatorial Pacific and its modelling
Hu Zeyong, Tang Maocang
1993, (2): 207-218.
Abstract:
In this paper, by analyzing the data of sea temperature in the Equatorial Western Pacific (EWP), we found that the sea temperature at sensitive district (WSST) (about at 6°N, depth of 125-150 m) is correlated negatively to the sea temperature in the ...
The mesoscale numerical simulation of the flow field of the Hainan Island and the Leizhou Peninsula
Tu Xiaoling, Zhou Mingyu, Sheng Shaohua
1993, (2): 219-235.
Abstract:
The flow field over Hainan Island and the Leizhou Peninsula in summer and winter is discussed with three-dimensional mesoscale model developed in the University of Virginia and using the representative meteorological data of January and July.

Marine Chemistry
Distribution of moretene, sterere, fernene, hopene and dienoic carboxylic acid in marine sediments in sea area of the Southern Ocean
Jiang Shanchun, Tang Yunqian
1993, (2): 237-247.
Abstract:
The soluble organic matters were extracted from marine sediments in the sea area of Southern Ocean by using organic solvents. The hydrocarbon and carboxylic acid fractions were separated with the thin layer chromatography. The organic compounds of 17...
Marine Geology and Geomorphology
Study of evolution forecast of the area of the Huanghe River mouth
Guo Yongsheng, Xu Xuegong, Fan Zhaomu, Wu Peihong, Zhu Xiaoge
1993, (2): 249-259.
Abstract:
From 1979 to 1989, the current Qingshuigou course of the Huanghe River formed a sub-delta which resembles a beak extending into the Laizhou Bay. It covers 618 km2 in area. To meet the needs of developing and constructing the Huanghe River Delta and u...
Marine Biology and Fishery
Studies on the role of marine bacteria in the upwelling ecosystem——Ⅰ.Bacterial biomass in the upwelling regions
Zheng Tianling, Cai Lizhe, Jiang Xianquan
1993, (2): 261-272.
Abstract:
Six cruises were carried out off the south bank of Fujian-Taiwan during the period of December 21, 1987 to November 15, 1988 to estimate the contribution of bacterial biomass carbon (BBC) to the totai particulate organic pools using epifluorescent mi...
Fauna of marine mammals in China
Wang Peilie
1993, (2): 273-278.
Abstract:
Marine mammals, 41 species in total including 8 species of Mysticeti, 27 species of Odontoceti, 5 species of Pinnipedia and only 1 species of Sirenia have been known and recorded in China. According to the number of species of China marine mammals in...
A simple method for the detection of hepatitis A virus in the environmental samples by polymerase chain reaction
Yang Feng, Xu Xun, Zhang Yusheng, Chen Rongzhong, Zhou Xiulan
1993, (2): 279-284.
Abstract:
Hepatitis A virus (HAV) is very persistent in the environment and is especially difficult to detect in the seafoods. In recent years, molecular cloning of the genome of HAV has led to sensitive polymerase chain reaction (PCR) method for the detection...
Effects of heavy metal ions on larval Penaeus chinensis and comparative study on their elimination methods
Yuan Youxian, Gao Chengnian, Zhang Duxi
1993, (2): 285-293.
Abstract:
In order to establish a new method to eliminate toxicities of heavy metal ions to larval penaeid shrimp, the effects of copper, zinc, lead and cadmium ions on larval metamorphosis of Penaeus chinensis at each stage were determined in detail, and two ...
Genetical study on the parthenogenesis in Laminaria japonica
Dai Jixun, Cui Jingjin, Ou Yulin, Fang Zongxi
1993, (2): 295-298.
Abstract:
The parthenogenesis and natural doubling of chromosomes in wild type female gametophytes of Laminaria japonica were studied. The results indicate that not all the female gametophytes from the wild type hybrid parent can propagate through parthenogene...
