Numerical study on residual current and its impact on mass transport in the Hangzhou Bay and the Changjiang Estuary Ⅰ.A3-D joint model of the Hangzhou Bay and the Changjiang Estuary
Zhu Shouxian, Shi Fengyan, Zhu Jianrong, Ding Pingxing
2001, (1): 1-13.
Abstract:
A 3-D numerical model is set up in a large domain covering the Hang zhou Bay and the Changjiang Estuary based on the ECOM model in orthogonal curvilinear coordinates.The numerical schemes for baroclinic pressure gradient (BPG) terms and convective te...
Three dimensional diagnostic, semidiagnostic and prognostic calculations of current in the East China Sea in April of 1994
Wang Huiqun, Yuan Yaochu
2001, (1): 15-28.
Abstract:
Three dimensional diagnostic, semidiagnostic and prognostic models in the a-coordinate are used to compute the current in the Fast China Sea with wind and hydrographic data obtained from the investigation of ocean fluxes in the East China Sea during ...
Three-dimensional numerical simulation for tide and tidal current in the Beibu Gulf
Sun Hongliang, Huang Weimin
2001, (1): 29-38.
Abstract:
By means of three-dimensional POM model, which computes the eddy viscosity coefficient based on two-order turbulent closed model, the tide and tidal current in the Beibu Gulf are simulated with fine grid.In the computed region, six islands are consid...
Marine Meteorology
Responses of CO2 in surface water in subtropical West Pacific to El Niño event
Xing Runan, Ma Liming, Qiao Ran, Wang Zhanggui
2001, (1): 39-50.
Abstract:
In order to investigate the relationships between the change of TCO2, △PCO2 and SST, current, upwelling and biological activities during El Niño event in the subtropical Pacific, the responses of TCO2 and △PCO2 in surface water in the subtropical Pac...

Study on detection of coastal water environment of China by ocean color remote sensing
Pan Delu, Mao Tianming, Li Shujing, Huang Haiqing
2001, (1): 51-63.
Abstract:
Coastal water environment is essentially enhanced by ocean color which is basically decided by substances concentration in water such as chlorophyll, suspended material and yellow substance.It is very difficult, even not possible, to detect water col...

Nutrients concentration and changes in decade-scale in the central Bohai Sea
Yu Zhigang, Mi Tiezhu, Yao Qingzhen, Xie Baodong, Zhang Jing
2001, (1): 65-75.
Abstract:
The nutrients contents and distributions are discussed briefly, based on the data obtained in 1998~1999.Besides explanation of the results, a 20-a time series data of nutrients and biological parameters for central Bohai Sea are reviewed.It is found ...
Narrow and broad senses on salinity scale
Bao Wanyou, Liu Ximin, Zhang Hao
2001, (1): 76-83.
Abstract:
The narrow sense and applicable limit of Practical Salinity Scale 1978 (PSS78) and volumetric titration using silver nitrate to measure the salinity of non-conservative oceanwater are discussed.The salinity obtained by electrical conductivity method ...
On sedimentation of phosphorus in specified area outside of the Changjiang Estuary
Zhou Huaiyang, Pan Jianming, Chen Jianfang, Wang Huaizhao, Y. Saito, Y. Kanai
2001, (1): 85-93.
Abstract:
Phosphorus content of surface sediments (0~1cm) sampled by multicorer in specified area (31°00'~32°00'N, 122°30'~124°00'E) outside of the Changjiang Estuary in October 1997 and May 1998 respectively is analyzed.Combined with the data of phosphorus co...

Geochemistry of trace elements and Sr-Nd isotopes of foraminifera shell from the Okinawa Trough
Meng Xianwei, Du Dewen, Cheng Zhenbo
2001, (1): 95-103.
Abstract:
Trace elemental associations and Sr-Nd isotopic compositions are of important to recognition of biogenic material from mixed marine sediments.The foraminifera shell from the Okinawa Trough strongly enrichesSr, P, Mn andBa, enriches Li, U, Th, Sc, Co,...
Linear magnetic anomalies and tectonic development of the middle Okinawa Trough
Liang Ruicai, Wu Jinlong, Liu Baohua, Wang Yong, Wang Shugong
2001, (1): 105-116.
Abstract:
By analyzing the magnetic anomalies, the linear magnetic anomalies in the middle Okinawa Trough are identified.It means that the crust along the spreading axis is broken, and new oceanic crust is formed.Geophysical data have revealed that a model of ...

Primary productivity in the western tropical Pacific and equatorial warm waters
Chen Xingqun, Zhang Ming, Chen Qihuan
2001, (1): 117-129.
Abstract:
Primary productivity in the western tropical Pacific and equatorial warm waters was studied in the WOCE cruise in November of 1991 and the TOGA-COARE cruise from November of 1992 to February of 1993.It is shown that the total amount of integrated chl...
