Distribution of chlorophyll a, photosynthesis and their relations to the environmental factors in the Central South China Sea     

Chen Xingqun  Chen Qihuan  Zhuang Liangzhong 《海洋学报(英文版)》1990,9(4):611-617

Some studies have been made on the variation of primary productivity in the Central South ChinaSea. This paper studies comprehensively the characteristics of chlorophyll a distributions in time andspace and the primary productivity, as well their relations to the environmental factors.Materals and methods During the comprehensive investigation in the Central South China Sea from September 1983 toDecember 1984, the distributions of chlorophyll a and primary productivity were studied. Figure 1shows the sampling stations and their range of investigation.  相似文献

A Preliminary Study of Quantitative Distribution of Benthic Animals in the East China Sea Continental Shelf and Its Adiacent Waters     

江锦祥  黄立强  孟凡  吴启泉  王慧珍  孙修勤 《海洋学报(英文版)》1985,4(4):648-649

In October and November of 1977 and September and October of 1978,a quantitative survey of benthic animals was conducted in the East China Sea Continental Shelf and its adjacent waters(26°00'-34°00'N,124°00'-129°00'E,water depth 39-1550m),where 307 stations were dredged and 1200 samples collected.  相似文献   

FORMATION MECHANISM AND DEVELOPMENTAL CONDITIONS OF TIDAL CURRENT RIDGES   总被引：1，自引：0，他引：1  

夏东兴  刘振夏 《海洋学报(英文版)》1986,5(2):247-255

This paper discusses mainly the formation mechanism and developmental conditions of tidal current ridges. The tidal current velocities of 1-3.5 knots and the supply of abundant loose sediments are the prerequisites for the formation of the tidal current ridges. The hydrodynamic mechanism is similar to that of straight rivers. In the trough between two ridges the tidal current moves forward in the form of two helical flows. The two flows converge and sink in the centre of the trough, and erode the trough deeply; they diverge and rise on the two sides of the trough, and accumulate the ridges. When the supply material and relief come to the dynamic equilibrium, the development of ridges keeps steady.  相似文献   

Gill surface architecture of mullet, Mugil soiuy (Basilewsky): A scanning electron microscope study     

Wang Liangchen  Guo Shuhua 《海洋学报(英文版)》1989,8(4):606-609

Specimens of Mugil soiuy were collected from the coastal waters of Bohai Sea in Tianjin. The gillfilaments were cut with fine scissors and soaked for 24h in a fixative consisting of 2.5% glutaralde-hyde in 0.1 mol l~(-1) phosporic acid buffer. After three washes in a buffer solution the tissue was fixedin a mixture of 1% osmium tetraoxide at 4℃ for 1h. The tissue was dehydrated in graded ethandethanols and dried. The tissue was examined and photographed with an SEM at an accelerating voltage  相似文献
