Abstract:
This paper is devoted to the study of the propagation of tide wave in a basin with variable cross-sectional area. With the W.K.B. method an analytic solution of amplitude is obtained. It is found that the motion of co-oscillating tide wave in a basin...

Abstract:
A contrasting study of the large-scale circulation features responsible for months or seasons with many hurricanes and those with few hurricanes has revealed that the frequency of hurricane formation over the North Atlantic Ocean is enhanced by the f...

Abstract:
In the light of the sea level synoptic charts from July to August for 1975-1978, we obtained more observed records of low latitudes by using the analysed stream and temperature-moisture field (or so called energy field θe field and θse field), the ma...

Abstract:
This article studies the interactions of trace-elements in seawater with clay minerals and presents a chemical model-the main action of cation exchange in lower concentration of Pb and the main action of surface precipitation in higher concentration ...

Abstract:
Research of chromium speciation in the Bohai Gulf showed that content of particulate chromium in estuarine area rea ched more than 90%, so it is an existing dominant speciation in the Bohai Gulf. Ratio between trivalent chromium to total dissolved ch...

Abstract:
This paper indicates that there is a maximum value of vertical distribution of dissolved oxygen in the South China Sea in summer, and that this maximum value in summer derives mainly from winter. A similar reservation occurs also in temperature under...

Abstract:
In sediments of the Central Pacific, water depth is the controlling factor of the distribution of Si, Al, Fe and CaCO3.In the shallow and subabysmal areas, CaCO3 content is much greater than that in the abysmal areas where Si, Al and Fe contents are ...

Abstract:
Analyses of clay mineralogy about 30 surface sediments indicate widespread occurrence of illite, kaolinite, chlorite and montmorillonite throughout the Bohai Sea. Illite is the most abundant mineral, averaging 60%, kaolinite, next to illite, is the m...

Abstract:
In this paper, a new method of making a quantitative comparison between the tectonic movement rates along the coastal areas is given. It is independent of any specific curve of sea level change. Meanwhile, by using the 14C data from samples of the Ho...

Abstract:
O-phthaldialdehyde is used for the determination of free amino acid in seawater by measuring the fluorescence produced by its reaction with the a-amino group of amino acids. This method is so sensitive that as little as 1-10 nM of amino acids and les...

Abstract:
Nine experiments were carried out on 39 healthy male adults for a total of 54 decompressions from N2-O2 saturation diving at the denths of 20-50 m. Excess supersaturation pressures of nitrogen dissolved in 1200 min tissue were calculated at all depth...

Abstract:
Combination of a fixed design wave height with various wave periods may exert quite different wave loads on ocean structure. The response of structure induced by mild sea state may be larger than that by severe sea state because the frequency of the ...
