| 1 | Estimating Synechococcus spp. growth rates and grazingpressure by heterotrophic nanoplankton in theEnglish Channel and the Celtic Sea显示文摘-Marine chroococcoid phycoerythrin - containing Synechococcus spp. recently have been implicated as a substantial component of the photosynthetic picoplankton in the ocean. Although the importance of Synechococcus as food sources for heterotrophic nanoplankton are now recognized, the information about its cycling of biomass and diel patterns is limited and the methodology used varies according to different authors. A selective metabolic inhibitor method was used to allow simultanous estimation of both growth rates and grazing disappearance rates of Synechococcus. Results obtained in the English Channel show growth rates ranging from 0. 25 to 0. 72 d-1 with an average value of 0. 51 d -1and grazing disappearance rates ranged from 0. 21 to 0. 64 d-1 (mean = 0. 44 d-1). Offshore in the Celtic Sea of the Northeast Atlantic Ocean, both rates were lower than in the channel. The similarity between average growth and grazing rates suggests a rapid recycling of Synechococcus biomass.

| 2 | Size fractionated biomass and productivity of phytoplankton and new production in the Prydz Bay and the adjacent Indian sector of the Southern Ocean during the austral summer 1998/1999显示文摘The paper deals with the studies on the cell abundance, the composition of dominant species, size fractionated biomass and productivity of phytoplankton, new production, the environmentally restricted mechanism in the Prydz Bay and the adjacent Indian sector of the Southern Ocean during the austral summer 1998/1999. The results showed that there was marked feature of spatial zonation in the sea areas investigated. In the Prydz Bay and its adjacent continental shelf, the biomass and productivity of phytoplankton were high; those of continental slope and open ocean area were obviously low. The nutrient concentration had opposite distribution trend, due to the consumption of phytoplankton. It mainly affected by the vertical stability of water column, grazing pressure of zooplankton, temperature and light etc.The results of size-fractionation showed that the average contribution of netplankton to total chlorophyll a in studied sea areas was 52.2%, those of nano- and picoplankton were 29.4% and 18.4%, respectively. The average contribution of netplankton to total primary production was 52.4%, those of nano- and picoplankton were 28.7% and 18.9%, separately. It is same as previous conclusion that the contribution of picoplankton to productivity is slightly larger than that to biomass of phytoplankton communities. The average new production and f-ratio were 230.6 mg/(m2·d) and 0.43, respectively. | Cai Yuming 1,3, Ning Xiuren 1,2,3, Zhu Genghai3, Shi Junxian3 1.

| 3 | Bacterioplankton production in dilution zone of the Changjiang (Yangtze) Estuary显示文摘The bacterioplankton production and bacterioplankton abundance were surveyed in dilution zone of the Changjiang Estuary and a mesocosm experimental device for enriched phosphate experiment and oil contaminated experiment was placed in the waters nearby Luhua Island during October 1997 and May 1998. The results showed that the average bacterioplankton production in spring was higher than that in autumn, the production at the surface water was higher than that at the bottom in the surveyed area; the higher values appeared in the middle of the area. The results from mesocosm experiment with adding phosphate and oil contaminated showed that the bacterioplankton production increased rising trend day by day during the experiment period. | Liu Zilin 1,2 , Koshikawa Hiroshi 3, Ning Xiuren 1,2 , Shi Junxian 2, Cai Yuming 1,21.KeyLaboratoryofSubmarineGeosciences,StateOceanicAdministration,China2.SecondInstituteofOceanography,StateOceanicAdministration,Hangzhou310012,China3.Nationa | 2001 | Acta Oceanologica Sinica2001，20，1： | 3 |
| 4 | Community structure of picoplankton abundance and biomass in the southern Huanghai Sea during the spring and autumn of 2006显示文摘During spring and autumn of 2006,the investigations on abundance,carbon biomass and distribution of picoplankton were carried out in the southern Huanghai Sea(Yellow Sea,sHS) . Three groups of picoplankton-Synechococcus(Syn) ,Picoeukaryotes(PEuk) and heterotrophic bacteria(BAC) were identified,but Prochlorococcus(Pro) was undetected. The average abundance of Syn and PEuk was lower in spring(5.0 and 1.3 × 10 3 cells/cm 3,respectively) than in autumn(92.4 and 2.7 × 10 3 cells/cm 3,respectively) ,but it was opposite for BAC(1.3 and 0.7 × 10 6 cells/cm 3 in spring and autumn,respectively) . And the total carbon biomass of picoplankton was higher in spring(37.23 ± 11.67) mg/m 3 than in autumn(21.29 ± 13.75) mg/m 3 . The ratios of the three cell abundance were 5:1:1 341 and 30:1:124 in spring and autumn,respectively. And the ratios of carbon biomass of them were 5:7:362 and 9:4:4 in spring and autumn,respectively. Seasonal distribution characteristics of Syn,PEuk,BAC were quite different from each other. In spring,Syn abundance decreased in turn in the central waters(where phytoplankton bloom in spring occurred) ,the southern waters and inshore waters of the Shandong Peninsula(where even Syn was undetected) ;the high values of PEuk abundance appeared in the central and southern waters and the inshore of the Shandong Peninsula;the abundance of BAC was nearly three order of magnitude higher than that of photosynthetic picoplankton,and high values appeared in the central waters. In autumn,Syn abundance in central waters was higher than that in surrounding waters,while for PEuk abundance,it decreased in turn in the inshore waters of the Shandong Peninsula,the southern waters and the central waters;BAC presented a complicated blocky type distribution. Sub-surface maximum of each group of picopalnkton appeared in both spring and autumn. Compared with the available literatures concerning the studied area,the range of Syn abundance was larger,and the abundance of BAC was higher. In addition,the conversion factors for calculating picoplanktonic carbon biomass were discussed,with the conversion factors which are different from previous studies in the same surveyed waters. The result of regression analysis showed that there was distinct positive correlation between BAC and photosynthetic picoplankton in spring(r=0.61,P <0.001) ,but no correlation was found in autumn. | LE Fengfeng NING Xiuren LIU Chenggang HAO Qiang SHI Junxian | 2010 | Acta Oceanologica Sinica2010，29，1： | 2 |

| 10 | Standing stock of phytoplankton and primary productivity in Penaeus orientalis larval multiplication releasing area of the Xiangshan Bay显示文摘The standing stock of phytoplankton (phy. ) and primary productivity (pp) in the Xiangshan Bay were observed in 1992. The results showed higher biological parameters in the bay. The average chlorophyll a (chl a) concentration was (3. 50 5. 93 ) mg/m3 and the primary productivity (444. 5 871. 0) mg/(m2 d). The distribution of chl a and productivity showed distinct spatial and temporal patterns in the bay. The continent influence was Obvious at the top of the bay, lower seawater exchange and higher stability led to higher standing stock of phytoplankton and productivity. At the bay mouth, seawater exchanged continuously with adjacent waters by rapid currents, resulting in fast and unstable exchange and lower standing stock of phytoplankton and primary productivity. The seasonal characters of those parameters were pronounced, in the sequence of spring, summer, autumn and winter. The results of size--fractionated showed that the average contribution of the nano--and picoplankton (< 20pm) to total chl a and productivity were 75 % and 87%, respectively, indicating their importance in phytoplankton community biomass and productivity of the Xiangshan Bay. | Liu Zilin Cai Yuming Shi Junxiang Ning Xiuren (1.

| 19 | Dynamic Properties of Long Large Cross-section Underground Structures in Dynamic Seismic Analysis显示文摘Seismic safety of underground structures is one of the main concerns in underground space exploitation.As the first step for dynamic seismic response analysis,the free vibration of long large cross-section underground structures is studied in the present paper.The general free transverse vibration motion equation of long large cross-section underground structure is derived with the comprehensive consideration of internal and external damping,effects of shear,cross-sectional rotational inertia and axial force,and a two-parameter soil model.In this way,Timoshenko's beam theory is extended.Two limit cases of free transverse vibration of underground structures are discussed.Parameter study shows that in general wave propagation velocities in structures increase with soil elastic parameters.However the influence of Winkler's parameter k-is significant while the effect of the second soil elastic parameter g-P is insignificant.The free vibration frequency of underground structures increases with relative wave number and soil elastic parameters.Unlike the influence of soil elastic parameters on wave propagation velocities,the influence of soil elastic parameters k-and g-P on the vibration frequency of underground structures have the same order;therefore the influence of the second soil parameter g-P on the free vibration of underground structures should not be neglected in dynamic seismic analysis of underground | Chen Canshou Qi Chengzhi Yang Xiuren Chen Guoxing Chen Jianjie | 2011 | Earthquake Research in China2011，25，3： | 0 |
| 20 | Standing Crop and Primary Production of Benthic Microalgae on the Tidal Flats in Yueqing Bay显示文摘The standing stock and primary production of benthic microalgae on tidal flats were measured seasonally at 3 transects (Puqing, Dahengchuang and Puqi) in Yueqing Bay during 2002 2003. The results showed that the integral chlorophyll a (Chl a) concentration in tidal flat mud exhibited a seasonal variation with the order of magnitude: winter (14.0 4.2 mg m-2) > spring (13.0 6.3 mg m-2) > autumn (7.7 5.9 mg m-2) > summer (4.6 3.2 mg m-2). The primary production showed an order of magnitude: spring (270.5 224.9 mgC m-2 d-1)>winter (238.7 225.5 mgC m-2 d-1)>autumn (214.1 56.2 mgC m-2 d-1)>summer (71.6 44.6 mgC m-2 d-1). Both chlorophyll a and primary production showed maximum values in the surface layer of sediment, and decreased rapidly with increasing depth due to sun light limitation. The results of variance analysis indicated that seasonal variation and tidal flat condition affected Chl a greatly, but had no significant effect on primary production. The annual primary production of benthic microalgae on tidal flats in Yueqing Bay was estimated at 16143 tons carbon, which is sufficient to support 1.02×105 tons shellfish production. The environmental factors affecting chlorophyll and primary production on the tidal flats in Yueqing Bay were discussed. By comparing with other bays on China's coast, it was observed that Yueqing Bay is a region with high benthic microalgae standing crop and primary production, which may be related to the type of its sediment. | HAO Qiang CAI Yuming NING Xiuren LIU Chenggang PENG Xin TANG Xuexi | 2011 | Journal of Ocean University of China2011，10，2： | 0 |
