Perturbed solution of sea-air oscillator for the El Niño/La Niña-Southern Oscillation mechanism
ZHOU Xianchun, LIN Yihua, WANG Hui, MO Jiaqi
2009, (3): 1-4.
Abstract:
A class of coupled system of the El Niño/La Niña-Southern Oscillation (ENSO) mechanism is studied. Using the perturbed theory, the asymptotic expansions of the solution for ENSO model are obtained and the asymptotic behavior of solution for correspon...
Energy budget of surface waves in the global ocean
TENG Yong, YANG Yongzeng, QIAO Fangli, LU Jing, YIN Xunqiang
2009, (3): 5-10.
Abstract:
Mechanical energy input from atmosphere and losses from wave-breaking dissipation of sea surface waves are estimated by a direct scheme. This scheme is based on the integration in the wavenumber space of the wind input and breaking dissipation source...
A numerical study of summertime expansion pattern of Changjiang (Yangtze) River diluted water
SHAN Feng, QIAO Fangli, XIA Changshui
2009, (3): 11-16.
Abstract:
Observations show that during summer especially in August, the northward expansion of the Changjiang(Yangtze) River diluted water (CRDW) is blocked in the vicinity of the Changjiang Estuary. To explain this phenomenon, Princeton ocean model (POM) is ...
Three-dimensional tidal current numerical model of the Oujiang Estuary
LI Mengguo, LI Wendan
2009, (3): 17-25.
Abstract:
The characteristics of three-dimensional (3-D) tidal current in the Oujiang Estuary are investigated according to in situ observations. The Oujiang Estuary has features of irregular coastline, complex topography, many islands, moveable boundary, and ...
Layer-block tectonics of Cenozoic basements and formation of intra-plate basins in Nansha micro-plate, southern South China Sea
LIU Hailing, XIE Guofa, LIN Qiujin, ZHENG Hongbo, LIU Yingchun
2009, (3): 26-39.
Abstract:
Layer-block tectonics (LBT) concept, with the core of pluralistic geodynamic outlook and multilayer-sliding tectonic outlook, is one of new keys to study 3-dimensional solid and its 4-dimensional evolution history of global tectonic system controlled...
Faulting, magmatism and crustal oceanization of the Okinawa Trough
GAO Jinyao, ZHANG Tao, FANG Yinxia, YANG Chuanguo, MEI Sai
2009, (3): 40-49.
Abstract:
The paper focuses on the characteristics of faulting and magmatism of the Okinawa Trough and the relation between them. En-echelon grabens are ranked oblique to the continental shelf edge uplift, and the Longwang uplift, the rifting block ridge in th...
Trophic relationships in the Changjiang River estuarine salt marshes: preliminary investigation from δ13C and δ15N analysis
QUAN Weimin, HUANG Danqing, CHU Tianjiang, SHENG Qiang, FU Cuizhang, CHEN Jiakuan, WU Jihua
2009, (3): 50-58.
Abstract:
To obtain information on food web structure in salt marshes of the Changjiang (Yangtze) River Estuary, the δ13C and δ15N values of primary producers and consumers were determined. The mean δ13C values of 31 dominant consumers ranged from -23.13‰ to -...
Growth of marine bacteria and ammonium regeneration from substrates in different C: N ratios
WANG Jiangtao, YIN Xiaonan
2009, (3): 59-64.
Abstract:
Natural assemblages of marine bacteria were chosen in a batch culture experiments. The impact of varying nitrogen substrate concentrations and the substrate C:N ratios (C:NS) on the bacterial C:N ratio (C:NB), the bacterial growth efficiency (BGE) an...
Modeling of suspended sediment transport with waveinduced longshore current in Huanghe (Yellow) River Delta
LI Changliang, LIANG Bingchen, ZHANG Jing
2009, (3): 65-74.
Abstract:
A three-dimensional suspended sediment model (SED) developed by the present authors is coupled with the combinatorial model of COHERENS (Luyten et al., 1999) (the three-dimensional coupled hydrodynamical-ecological model for Regional and Shelf Seas) ...
Nonlinear numerical simulation on extreme-wave kinematics
NING Dezhi, TENG Bin, LIU Shuxue
2009, (3): 75-81.
Abstract:
A fully nonlinear numerical model based on a time-domain higher-order boundary element method (HOBEM) is founded to simulate the kinematics of extreme waves. In the model, the fully nonlinear free surface boundary conditions are satisfied and a semi-...
Wave decomposition phenomenon and spectrum evolution over submerged bars
LI Benxia, YU Xiping
2009, (3): 82-92.
Abstract:
Wave decomposition phenomenon and spectrum evolution over submerged bars are investigated by a previously developed numerical model. First, the computed free surface displacements of regular waves at various locations are compared with the available ...
Feedback between tidal hydrodynamics and morphological changes induced by natural process and human interventions in a wave-dominated tidal inlet: Xiaohai, Hainan, China
GONG Wenping, SHEN Jian, JIA Jianjun
2009, (3): 93-113.
Abstract:
The feedback between morphological evolution and tidal hydrodynamics in a wave-dominated tidal inlet, Xiaohai, China is investigated through data analysis and numerical model experiments. Historically, Xiaohai Inlet had two openings, located at the n...

A study of ice response spectra
LIU Chunguang, JIA Lingling
2009, (3): 114-119.
Abstract:
Some problems concerning the ice forces and ice response spectra are studied from both theoretical and practical points of view. On the basis of structural analysis,the analysis method of ice response spectra is proposed, since it plays an important ...
PAH-biodegradation potential of indigenous microorganisms: evidence from the respiratory activity of surface sediments in the Quanzhou Bay in China
GU Tihua, WANG Zhaoshou, TIAN Yun, HUANG Bangqin, ZHENG Tianling
2009, (3): 120-128.
Abstract:
Seven stations were established in the Quanzhou Bay (24.73°-24.96°N, 118.50°-118.70°E) in China on three cruises to determine the concentrations of polycyclic aromatic hydrocarbons (PAHs) and the numbers of PAH-degrading bacteria in surface sediments...
