海洋微生物学的主要任务     

A.E.科利斯 《海洋与湖沼》1958,1(2):337-343

海——微生物栖息的特殊环境。特殊的盐类成分,低温,高压,低浓度的有机物质,植物及动物区系的稀少等组成了微生物生命活动的广阔海洋区域一些主要生态特征。 海洋中最初的微生物学研究,早在上一世纪就已进行了,但足它们局限于较狭小的任务——  相似文献   

东海东北海域环流的数值研究     

李龙章  T. Ichiye 《海洋学报》1986,8(2):142-150

本文用二维正压非线性模式研究东海东北海域(包括朝鲜海峡)的流型。该海域的环流主要为海底地形所支配。科氏效应对环流的变动很重要,β效应则是次要的。作为研究该海域的第一步,风应力未予考虑。该海域的海流在夏季比冬季强,朝鲜海峡一带尤为明显,这与所观察到的对马海流输运的年变化是一致的。在附录中导出了带底应力的应涡守恒方程,并用以分析该海域东北和东南部的流场,以便与数值结果进行比较。  相似文献   

Responses of a Mediterranean soft bottom community to short-term (1993-1996) hydrological changes in the Rhone river   总被引：1，自引：0，他引：1  

Salen-Picard C  Arlhac D  Alliot E 《Marine environmental research》2003,55(5):409-427

The polychaete fauna of muddy bottoms off the Rhone delta (NW Mediterranean) was seasonally sampled at two sites at 70 m depth, from 1993 to 1996. During this period, five severe flood events occurred. A clustering analysis (distance coefficient of Whittaker) and three way fixed factor ANOVAs (site x season x year) showed strong year-to-year changes in species density and community structure, changes that masked seasonal variations. Total density increased by a factor of 3 and density of most species significantly increased following the first flooding event. Changes in the community structure were due to the successive dominance of a few species. The opportunistic species, such as Cossura sp., Mediomastus sp. and Polycirrus sp., exhibited peaks in density 1-3 months after the flood. These peaks were followed by a drastic decline. For species with a long life span, such as Sternaspis scutata, a slower but continuous increase in density was observed which was maintained for several months. The density fluctuations of these species exhibited a good correlation with river flow with time lags of 1-2 years. The successional dynamics observed are explained according to the geographical origin of the floods and the biology and feeding ecology of species.  相似文献   

Seasonal variation in lysosomal destabilization in oysters,Crassostrea virginica     

Ringwood AH  Hoguet J  Keppler CJ 《Marine environmental research》2002,54(3-5):793-797

Lysosomal destabilization assays have been used as valuable biomarkers of pollutant exposures in a variety of bivalve and fish species. The responses of oysters, Crassostrea virginica, deployed at and native to various reference and degraded sites were evaluated for lysosomal destabilization during both summer and winter seasons. In both native and deployed oysters, lysosomal destabilization rates tended to be higher during the winter at both reference and polluted sites. There are at least two hypothetical explanations. Greater lysosomal destabilization rates may be related to physiological changes associated with mobilization of nutrient reserves during the winter and gametogenesis. However, lysosomal destabilization in deployed oysters was correlated with tissue metal concentrations. These data also support a second hypothesis that seasonal differences in physico-chemical factors (such as reduced levels of acid volatile sulfides) may increase the bioavailability of metals during the winter so that adverse effects are more pronounced.  相似文献

A NEW MODEL FOR PEBBLE BEACH TRACER DISPERSAL     

A. T. WILLIAMS 《海洋学报(英文版)》1987,6(2):229-234

A series of eight tracer experiments were carried out over one year (1983) on a low energy, macro-tidal beach in South Wales, UK. Tracer movement was monitored and 30 pebbles adjacent to coloured tracer pebbles were measured. Measurements were of the A, B, and C axes, roundness, Maximum Projection Sphericity and Oblate-Prolate indices. Analysis shows that through time, the percentage rejection of these properties increased. It is theorised that the surface tracers are 'misfits' or 'rejects' which have not found their equilibrium position in the pebble facies.  相似文献
