A numerical prediction model of strong thermocline in the Bohai and the Huanghai Seas
Wang Zongshan, Xu Bochang, Jin Meibing, Zou Emei, Li Fanhua
1998, (2): 141-154.
Abstract:
In this paper, the predecessors' research results of the numerical prediction models of vertical sea temperature structure calculation are reviewed and assessed, whereby a three-dimensional numerical prediction model of a strong thermocline is establ...
A nonlinear model for nonbreaking shoaling random waves
Liu Xin'an Huang Peiji, Chen Xueying, Hu Zejian
1998, (2): 155-165.
Abstract:
In this paper,the spatial evolution of the third-order moment (i.e.,the skewness) of the sea surface elevalion for nonbreaking shoaling random waves versus Hs/d is analyzed by using the data obtained in field and laboratory. Using the empirical relat...
Numerical sea ice prediction in China
Wu Huiding, Bai Shan, Zhang Zhanhai
1998, (2): 167-185.
Abstract:
A dynamic-thermodynamic ice model with three levels for simulating the ice growth, decay and drift in the Bohai Sea is presented on the basis of review of the climate and ice conditions in the Bohai Sea and the existing sea ice and the existing sea i...
Effects of iron on growth, degree of pigmentization and nitrogen assimilation in Skeletonema costatum
Zheng Airong, Chen Cimei, Zhou Ciyoul, Chen Yuzhou
1998, (2): 187-196.
Abstract:
The effects of iron and the interaction between iron and nitrogen on the growth, degree of pigmentization and nitrogen assimilation of S. costaturn are studied. The results show that with the increase of iron concentration from 3×10-8 to 5×10-6 mol/d...
Studies on seawater self-purification capacity to heavy metals in the Haikou Bay
Chen Chunhua
1998, (2): 197-207.
Abstract:
By combining hydrological exchange with chemical self-purification, the seawater self-purification capacity to heavy metals was studied, and the calculated results show that the hydrological exchange ratio during spring tide is 32.0%, and is 5.4% dur...
Tidal bedforms in eastern part of the Bohai Sea
Liu Zhenxia, S. Berne, Wang Kuiyang, T. Marsset, Xia Dongxing, Tang Yuxiang, J. F. Bourillet
1998, (2): 209-231.
Abstract:
A system of tidal bedforms has developed in the part of the Bohai Sea. It consists of the Laotieshan Channel, the Liaodong Shoal and the Shoal. The first of these is a tidal current scour region and the other two are tidal current depositional region...
Propagation and growth of Ponnotheres pholadis living in mantle cavity of Hiatula acuta
Yang Yaocong, Li Fuxuel, Cai Lizhe
1998, (2): 233-241.
Abstract:
This paper presents the study of the propagation and alternation of generations of Pinnotheres pholadis by observing yearly development and measuring carapace breadth of P.pholadis living in mantle cavity of Hiatula acuta. The reproductive period of ...
Study on diel rhythm of chlorophyll a and photosynthesis in nearshore waters of Qingdao
Mao Xinghua, Zhu Mingyuan, Yang Xiaolong, Hao Yawei, John Cullen
1998, (2): 243-254.
Abstract:
A study was made on the dial rhythm and variation of Chl a and photosynthesis in the nearshore of qingdao. Both Chl a and photosynthesis show obvious dial rhythm; the peak value of surface Chl a appeared in the afternoon,while bottom Chl a around noo...

Hu Ruijin, Zhou Faxiu, Liu Qi
1998, (2): 255-265.
Abstract:
Earthquake-induced hydrodynamic pressure of cylindrical structure in extreme shallow water
Li Changsheng, Tang Yougang, Xiang Zhongquan
1998, (2): 267-276.
Abstract:
