Volume and heat transports and material fluxes in the East China Sea during April 1994
Yuan Yaochu, Pan Ziqin, Wang Huiqun, Hu Dunxin, Guan Weibing, Xu Weiyi, Cui Maochang
1999, (4): 449-457.
Abstract:
A modified inverse method is used to compute the volume transport(VT),the heat transport (HT) and the horizontal material fluxes in the East China Sea with data of CTD,TCO2,DOC,POC,etc.obtained in April 1994.In April 1994 VT and HTthrough Section PN ...
Variability of the Kuroshio in the East China Sea in 1995
Liu Yonggang, Yuan Yaochu
1999, (4): 459-475.
Abstract:
A modified inverse method is used to oanpute the Kurnshio in the East China Sea with the CTD and wind data collected by R/V Chofu Maru during four cruises of 1995.The computed results show that:(1) The volume trasport (herafter VT) of the Kuroshio th...
A baroclinic typhoon model with a moving multi-nested grid and variational adjustment initialization Ⅱ. Forecast experiments
Wu Huiding, Yang Xuelian, Bai Shan, Li Guoqing
1999, (4): 477-493.
Abstract:
A 3-dimensional baroclinic typhoon model with a moving multi-nested grid and its initialization are described first.Prediction results are improved by using a simple but effective data assimilation method in which the initial field is adjusted by the...
Steady motion and spiral patterns in typhoon
Liu Shikuo, Liang Fuming, Liu Shida, Xin Guojun
1999, (4): 495-504.
Abstract:
By using the equations describing typhoons in the atmosphere,the steady three-dimensional stream field and the corresponding pressure and temperature fields are obtained. The three-dimensional velocity fields construct a nonlinear autonanous system i...
Response of western equatorial Pacific to a westerly wind burst
Chai Fei, Xue Huijie
1999, (4): 505-514.
Abstract:
Atmospheric jets-winds with shear-can induse a vertical oceanic circulation with upwelling and downwelling even over the open ocean in regions where the Coriolis parameter can be regarded as a constant.Winds with no shears that blow parallel to the e...
Development of acoustic suspended sediment monitor
Zhang Shuying, Li Yunwu, Guo Jijie
1999, (4): 515-521.
Abstract:
An acoustic suspended sediment monitor (ASSM) has been developed for the observation of suspatded sediment ooncanration profiler in water,rmnitoring pollutants in water and for the studies of ooestal sediment trensportatmn and deposition.The determin...
Calculation of geoid undulations and gravity anomalies in the Northwest Pacific by using the Topex/Poseidon and Geosat altimeter data
Pan Jiayi, Wang Junqin, Wang Yanfeng, Zhang Xinmei, Yuan Yeli, Zheng Quan'an
1999, (4): 523-533.
Abstract:
The geoid undulations in the Northwest Pacific were calculated by using the Topex/Paseidon and Geoeat altirreter data.Firstly the bias between two types of the altimeter data was removed and the geoid undulations in the Northwest Pacific were acquire...
In-situ calibration of acoustic measurements of suspended sediment
Guo Jijie, Ren inifa, Li Yunwu
1999, (4): 535-542.
Abstract:
The key to the problem of probing the concentration of suspended sediment in water and its variation with eooustic equipment is how to calibrate the obtained data.Combining the acoustic backscatter intensity data with the real concentration of suspen...
Characteristics of metals in atmosphere over the western Taiwan Strait Ⅱ. Sources and fluxes
Chen Liqi, Wang Zhihong, Yang Xulin, Yu Qun
1999, (4): 543-554.
Abstract:
Atmospheric metals over the western Taiwan Strait are studied and their sources are identified.Al and Fe are mainly from crustal soil.A little amount of Fe is from pollution.Pb and Cd are mainly from pollution sources.A little amount of Pb is from cr...
Isolation and identification of alginate-degrading bacteria and formation of alginase
Han Baeqin, Dai Jixun, Wang Hai
1999, (4): 555-561.
Abstract:
Five strains of alginate-degrading bacteria were isolated from the decaying parts of Laminaria japonica and Undaria pinnatifrda and identified as Alteromrnas esppjiana (Strain A101,A102,A103,A105)and Al-teromonas macleorlii(Strain A104).When incubate...
Ecological characteristics of phytoplankton community from eutrophic waters in the Maluan Bay
Yang Qingliang, Chen Qihuan, Lin Jinmei, Lin Gengrning, Chen Xingqun
1999, (4): 563-580.
Abstract:
The present study is based on the analysis ohthe data collected in 10 cruises during the periods of 2 surveys (from May 1992 to January 1993 and from August 1993 to May 1994).The resulu show that the number of phytoplanktat species in highly eutrophi...

Abstract:
Based on data of demersal trawl samples from 1987 to 1988 in the Zhujiang Estuary and its adjacent watens,relationships between fish community and environmental factors are studied by using classification,MDS ordination and several community paramete...
