The south china {2. (SCS) is one of the largest marginal {2.s 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

对流行病学分析显示大珠母贝幼虫群体的死亡是以暴发性方式发生,从胚胎发育前期至变态期,幼虫存在两个死亡高峰,分别位于壳顶期之前或壳顶期和壳顶后期.大珠母贝幼虫群体的死亡率与RLO感染之间存在显著的相关性,在RLO感染的高峰之后均相应伴随幼虫群体死亡率的高峰,随着RLO感染率和感染强度的降低,幼虫群体死亡率也明显降低.在TEM下未发现未受精卵母细胞、受精卵和胚胎早期幼虫感染RLO,最先出现RLO包涵体阳性感染的时期为2.h尚未摄食的D形期幼虫,故认为RLO可能不是通过垂直传播,而是通过外界接触感染的方式感染宿主,贝体感染至发病死亡存在潜伏期.

Nappe structure, as was first discovered by the authors during the regional geological survey at the scale of 1:50,000 in The Jinggang Mountain, is mainly comprised of a series of NNE-NE-striking thrust fault zones and thrust sheets among them. Sinian, Cambrian, Ordovician, Devonian, Carboniferous,Triassic, Jurassic and Cretaceous strata are involved in the thrust nappe system. The nappe structure is of the type of duplex structures formed as a result of the earlier stage migration from SE to NW and late stage migration from E to W of sedimentary cover or basement strata. Formation of the nappe structure in the studied area involves two main epochs: Early Yanshanian and Late Yanshanian to Early Himalayan. The mineral deposits and the buried coalfields in the area, especially the latter, are extensively controlled by the nappe structure.

The effect of temperature and salinity on the photosynthetic and respiratory rates of some seaweeds are reported. The regression equations for the seaweeds and their correlograms are discussed and *** results indicate that the photosynthetic rate of E. binghamiae fronds shows a significant negative linear correlation （p2.-35℃）, the optimum temperature being 2.℃, while for the others there is a conic correlation between photosynthetic rate and *** optimum temperature for photosynthesis is 2.-2.℃ for two species of Porphyra fronds, 2.-2.℃ for Gracilaria sp. thalli and 2.-30℃ for V. conglobata and S. hemiphyllum fronds, separately. The rates of respiration for all the studied species increase linearly with increasing temperature from 18 to 35℃. The optimum salinities for photosynthesis range from 2. to 32.for two species of Gracilaria, whose respiratory rates decrease gradually with increasing salinity.

Physical processes associated with onset of the 1998 Asian summer monsoon were examined in detail using multi-source datasets. We demonstrated that strong ocean-atmosphere-land interaction in the northern Indian Ocean and tropical Asian area during spring is a fundamental factor that induces the genesis and development of a monsoon onset vortex over the Bay of Bengal (BOB), with the vortex in turn triggering onset of the Asian summer monsoon. In spring, strong surface sensible heating over India and the Indochina Peninsula is transferred to the atmosphere, forming prominent in situ cyclonic circulation, with anticyclonic circulations over the Arabian sea and northern BOB where the ocean receives abundant solar radiation. The corresponding surface winds along the North Indian Ocean coastal areas cause the ocean to produce the in situ offshore currents and upwelling, resulting in sea surface temperature (SST) cooling. With precipitation on the Indochina Peninsula increasing from late April to early May, the offshore current disappears in the eastern BOB or develops into an onshore current, leading to SST increasing. A southwest-northeast oriented spring BOB warm pool with SST >31°C forms in a band from the southeastern Arabian sea to the eastern BOB. In early May, the Somali cross-equatorial flow forms due to the meridional SST gradient between the two hemispheres, and surface sensible heat over the African land surface. The Somali flow overlaps in phase with the anticyclone over the northern Arabian sea in the course of its inertial fluctuation along the equator. The convergent cold northerlies on the eastern side of the anticyclone cause the westerly in the inertial trough to increase rapidly, so that enhanced sensible heat is released from the sea surface into the atmosphere. The cyclonic vorticity forced by such sensible heating is superimposed on the inertial trough, leading to its further increase in vorticity strength. Since atmospheric inertial motion is destr

Tectonic stress at various depths has been computed by means of the finite element method inthe south china {2. crustobody. The conclusion is that the distribution of the stress is: - 5. 1～3. 2. MPa (130 km), -5～2. 9 MPa (8O km), -5. 5～2. 15 MPa (3o 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 {2. is preliminarily discussed.

The spectral absorption coefficient of phytoplankton in coastal waters of southern china is investigated. Large variations in the absorption coefficient of phytoplankton are found. The absorption coefficient of phytoplankton at 443 nm ranged from 0.006 m -1 to 0.484 m -1 , with an average value of 0.067 m -1 . The chlorophyll specific absorption coefficient of phytoplankton is also a bio optical variable, with a spectrally averaged value of 0.02. m 2.mg -1 . The variations of chlorophyll specific absorption coefficient are mainly attributed to pigment composition of phytoplankton and package effect. The chlorophyll specific absorption coefficient of phytoplankton decreases with the increasing of chlorophyll a concentration. This relationship can be described by a power law function, with the parameters and the coefficient of determination r 2.as functions of wavelength,but the parameters describing the relationships in present study differed from that in Case 1 waters, thus the regional adjustment of model parameters was of particular significance for improving the accuracy of bio optical algorithms for estimation of Chl a concentration and primary production from remotely sensed data. Regression analysis of reflectance ( R rs ) ratio and absorption coefficient of phytoplankton ( a ph ) indicates a close correlation between them, which means that it is possible to retrieve absorption coefficient of phytoplankton using ocean color remote sensing data in optically complex coastal waters.
