The result of an analysis of mollusca remains collected from the Chukchi sea, Beaufort sea and Bering sea in the First {3. National Arctic Research Expedition, from July to September, 1999 is presented. Seventeen species of mollusca have been identified, which belong to two classes: Bivalvia and Gastropoda. The compositions of the mollusca are very simple. According to the distribution pattern two groups may be distinguished among molluscan species. The Pan-Arctic and circumboreal group comprises Nuculana pernula, ***, Nucula bellotii, Astarte montagui, Seripes groenlandicus, Macoma calcarea, M. moesta alaskana, Liocyrna fluctuosa, Mya pseudoarenaria and Turritella polaris. Three species, Cyclocardia crebricostata, Trichotrois coronata and Argobuccinum oregonense are components of the Pan-Arctic and Pacific boreal group. With regard to feeding habits, detritus feeders dominate. There are 7 species of detritus feeders, i.e., Nuculana pernula, N. radiata, Nucula bellotii, Macoma calcarea, M. moesta alaskana, Macoma sp. and Trichotropis coronata. Detritus feeders are dominant with regard to the numbers of species as well as to the frequency of occurrence. Macoma calcarea is the most abundant species.

Geotectonica et Metallogenia 1998年第Z2期22卷 128-135页

作者： Zhan Wenhuan and Tang Cheng(south china sea {3. of oceanology, Academia Sinica, guangzhou 510301 )

Tectonic stress at various depths has been computed by means of the finite element method inthe south china sea crustobody. The conclusion is that the distribution of the stress is: - 5. 1～3. 25 MPa (13. km), -5～2. 9 MPa (8O km), -5. 5～2- 15 MPa (3. km), -3. 6～0. 67 MPa (10km). and -2. 5～0. 11 MPa in the surface of crust. The interaction between tectonic stress andcrustobody movement in the south china sea is preliminarily discussed.

Progress in Natural Science:Materials International 2003年第7期 3-10页

The south china sea (SCS) is one of the largest {3. seas in the western Pacific. Its northern part has the features of a passive continental margin. The studies of deep crustal structure in this area are very important for understanding the tectonic nature, evolution history, basin formation of the northern margin, and the origin of the SCS. In the past decades, the deep seismic experiments of crustal studies in the northern SCS have gone through three stages, namely the sonobuoy, two-ship Expanding Spread Profile (ESP), and Ocean Bottom Hydrophone/Seismometer (OBH/OBS). Along the continental slope, the sonobuoy experiments provided useful information about the velocity structure of the upper crust, while the ESP data recorded for the first time the seismic signals from deep crustal structure and Moho interface. And the OBH/OBS profiles revealed the crustal structure in much greater detail. This paper first gives a brief historical review of these deep seismic experiments and studies, then a summar

Journal of oceanology and Limnology 1984年第2期2卷 133-140页

作者： Zheng Jianlu, Wang Zhaoding, Lin Zhiqing, Li Zijiang, Zhu Zhuohong and Chen Jinsi(south china sea {3. of oceanology, Academia Sinica, guangzhou) south china sea {3. of oceanology Academia Sinica Guangzhou China

Nine chemical species of Zn, Cd, Pb and Cu in the Zhujiang River estuary were measured by using the technique of ion-exchange, ultraviolet irradiation and anodic stripping voltammetry. According to the distribution of the nine species in percentage an estuarine chemical pattern of the metal elements Zn, Cd, Pb and Cu in the Zhujiang River estuary was roughly made, and it is suggested that this estuary has relatively great self purifying ability in respect to heavy metal pollution.

In May of 2007,the second generation selected （SS） and control （SC） groups of pearl oyster Pinctada martensii were established by selecting 10% breeders with the largest and mean shell length,respectively,from the first generation selected *** performance of the SS and SC groups were compared on the basis of measurement data at Days 8,18,60,95,195 and *** Day 3.5,100 individuals （60.0–75.0 mm at shell length） were sampled from each group and then subjected to the experiment where physiological parameters such as filtrate rate,oxygen consumption and ammonia excretion were measured at 15,20,25 and 3.°*** results show that the SS group had significantly larger mean shell length and shell height than the SC group at Days 8,18,60,95,195 and 3.5 （P 0.05）.The genetic gains at different ages varied from 6.0% to 17.0% for shell length and 5.7% to 14.6% for shell height,*** 15,20,25 and 3. ° C,the SS groups had significantly larger filtrate rate than the SC group （P 0.05）.At 15 and 25 °C,the differences in oxygen consumption rate between the SS and SC groups were not significant （P 0.05）.At 20 and 3. °C,however,the oxygen consumption rate of the SS group was significantly larger than the SC group （P 0.05）.At 15,20,25 and 3. °C,there were no significant differences in ammonia excretion rate between the SS and SC groups （P 0.05）.The present results indicate that there existed considerable genetic variability in the base population and a further selection could be likely *** selection for faster growth might produce animals that had higher intake of metabolizable energy by virtue of faster filtrating behavior.

Recent geophysical surveys and basin modeling suggest that the No.1 fault in the Ying- gehai basin (YGHB) is the seaward elongation of the Red River fault zone (RRFZ) in the south china sea (SCS). The RRFZ, which separates the south china and Indochina block, extends first along the Yuedong fault, offshore of Vietnam, and then continues southward and breaks off into two branches: the Lupar fault and the Tinjia fault. The southern extension of the Lupar fault dies out beneath the NW Borneo while the Tinjia fault extends southeast and reaches the Brunei-Sabah area. According to the gravity and geomagnetic data, and the tectonic evolution of the basins, there are different evolution histories between the Wan’an basin (WAB) and the basins in the Nansha block. The Tinjia fault may be the boundary between the Balingian block and the Nansha block. Hence, the line linking the Yue- dong fault and the Tinjia fault, which both are continental margin faults and strike-slip ones in the geological evolution histories, constitute the boundary between the Indochina and Nansha block. The Lupar fault, in contrast, is an intraplate fault within the Indochina block. The results provide new hints for reconstructing the tectonic evolution history of the RRFZ and the opening of the SCS, and also a framework for hydrocarbon prospecting in the region.

Paleomagnetism and paleoclimate change in the south china sea since the late Pleistocene

Acta Oceanologica Sinica 1992年第4期11卷 573-581页

作者： Xidong Chen, Douglas F. Williams, Yuan Youren, Wang Baogui, Tang Xianzan, Fan Shiqing and Liu Zongyang 1. University of south Carolina, USA2. south china {3. institute of oceanology, Academia Sinica, guangzhou 510301, china

Signal processing techniques of cross-correlation, power spectral analysis and cross-power spectral analysis are used to determine the relationships between paleomagnetic properties and the oxygen isotope record of the south china sea during the late Pleistocene. On the basis of correlation tests between the δ18O time series of cores V3.and A15 with the paleomagnetic properties of core SCS01, five events of susceptibility and intensity of natural remanent magnetization are identified as glacial events corresponding to δ18O positive events. The magnetic properties of the sediments which are independent of the geomagnetic field are sensitive climatic indicators which have frequencies corresponding to the Milankovitch orbital parameters.

The Denglou Cape, southwest of the Leizhou Peninsula, is the most typical tropical coast in the continent of *** coastal geomorphic development basics of the geology and Quaternary environment change are discussed. Aerial photograph interpretation with fieldwork is applied to draw the outlines of geomorphic types. Based on the investigative data, the exogenic forces and marine organism conditions concerning tropical coast development in the area are expounded, and coastal dynamo-deposition geomorphic bodies are analysed, mainly with sea cliff-abrasion platform,barrier-lagoon system, modern beach, coral reef and mangrove tidal flat, and the general process of coastal evolution at this area, as well as coastline changes since middle Holocene transgression.
