Fronts and transport of suspended matter in the Hangzhou Bay
Su Jilan, Wang Kangshan, Li Yan
1993, (1): 1-15.
Abstract:
A persistent, year-round NE-SW front is found to exist inside the Hangzhou Bay. This front is actually the merging of the secondary Changjiang plume front from the bay mouth and the Qiantang plume front from the upstream side of the bay. During neap ...
Hydrographic features of the plume front in the Hangzhou Bay
Wang Kangshan, Su Jilan
1993, (1): 17-28.
Abstract:
A description is given of the distribution, spacial and temporal variation, mixing and transportation processes about the plume front in the Hangzhou Bay. This front is performed as a group of interfaces among, the water masses situated in the bay. A...
Residual currents in plume front zone of the Hangzhou Bay
Chen Wei, Huang Daji, Yang Zhaoqing
1993, (1): 29-37.
Abstract:
It is of some limitations to analyse residual currents by means of the 25 h anchored current measurements. On the basis of the drift tracking and the mooring system data, here, analyses have been done aiming at the structural characteristics and the ...
Suspended sediment transport of the Hangzhou Bay and its related hydrodynamic analyses
Li Bogen, Yang Zhaoqing, Xie Qinchun
1993, (1): 39-50.
Abstract:
The 25-h measurements of current speed, flow direction, water depth, suspended sediment concentration and salinity were carried out at six anchored stations in the study area during spring and neap tides in winter of 1987 and summer of 1989. Caculati...
Study on fluctuations of plume front and turbidity maximum in the Hangzhou Bay by remote sensing data
Li Yan, Li Jing, Su Jilan, Ren Fuhu
1993, (1): 51-62.
Abstract:
On the basis of the time series of AVHRR data from NOAA satellites and the geographical information system PURSIS, fluctuations of the plume front and the turbidity maximum in the Hangzhou Bay, reflected by the distributions of temperature and suspen...
A classification of hydrological climatic seasons in the China seas
Chen Shangji, He Weihuan, Yao Shiyu, Zhang Shudong
1993, (1): 63-78.
Abstract:
By using a method of boundary temperature index of seasons, a classification of hydrological climatic seasons in the China seas is made on the basis statistics of the sea surface air and water temperatures over the years. The results indicate that th...
Dimethyl sulfide in the atmospheric surface layer of the Equatorial Pacific Ocean
Li Xingsheng, F. Parungo, C. Nagamoto, S. Hoyt
1993, (1): 79-91.
Abstract:
This paper reports a case study of atmospheric stability effect on dimethyl sulfide(DMS) concentration in the air. Investigation includes model simulation and field measurements over the Pacific Ocean. DMS concentration in surface sea water and in th...
Analysis of 1989/1990 main physical fields for air-sea coupled system in the tropical western Pacific
Yao Huadong, Jiang Dayong, Liu Yimin
1993, (1): 93-105.
Abstract:
In this paper, the marine ship observation data sets in the seventh (October 16-December 4. 1989) and eighth (June 1-July 16, 1990) cruises of PRC-US tropical ocean and global atmosphere (TOGA) joint scientific investigation in the tropical western P...
The source of heavy metals and its indication to the sediment transfer in the Hangzhou Bay
Liao Xiangui, Zhang Xiangjun, Ying Shili, Wei Linying, Zhu Linfan
1993, (1): 107-114.
Abstract:
Suspended matters are important carriers of heavy metals in the hydrocycle.
In this paper, the field investigation, lab. experiment and "corresponding analysis" were made to study sources of the heavy metals and the transfer of suspended matters from ...
Geochemical characteristic of hydrocarbon compounds in the Hangzhou Bay
Lu Bin, Zhu Guihai, Zheng Shilong, Xiong Jian, Shi Jianzhong
1993, (1): 115-132.
Abstract:
The source and distribution of the organic pollutants such as the oil, n-alkanes,aromatic,and the pesticide in the water column, suspended particulates and surface sediments in the Hangzhou Bay (HB) during winter 1987 and summer 1988 are studied with...
Relationship between the characteristics of landforms and sediments as well as the plume front in the Hangzhou Bay
Feng Yingjun, Li Yan, Li Bogen
1993, (1): 133-144.
Abstract:
Sedimentary environments in the Hangzhou Bay are introduced by a three-subregional landform pattern and a sedimentation map with six major sedimentation types. The geographic setting, sediment transportation and sedimentation in different subregions ...
The distribution characteristics of clay minerals in the northern South China Sea
Tang Zhili, Wang Youqiang
1993, (1): 145-157.
Abstract:
The clay minearals are composed of illite, chlorite, kaolinite, montmorillonite and mixed-layer minerals in the submarine sediments of the northern South China Sea. Three types of clay mineral zone can be recognized on the basis of the distributive r...
Ecological characteristics of the abundance and distribution of bacteria in the waters nearby the front of the Hangzhou Bay

1993, (1): 159-167.
Abstract:
Abundance of total bacteria, heterotrophic bacteria, coliform and oil degradable bacteria and their relations with salinity and suspended matter in the frontal waters in the Hangzhou Bay are described. The results obtained show that the highest abund...
