Impact of sea ice on harbor operation and countermeasures;

The countermeasure and the impact from sea ice on shipping in shallow water area in north of Liaodong bay;

The desalinization of Bohai sea ice and its use value as fresh water resource;

Study on the revised model for extraction of sea-ice area in the Bohai Sea based on remote sensing data;

Based on the review of research progress of monitoring sea-ice and its shortcomings, obtaining sea-ice area by extraction of remote sensing data being very essential work was pointed out in this paper.

Based on the Arctic 1°×1° sea-ice area index,500hPa heights,sea surface pressure(SLP) and the China 160 Stations temperature data,the relationship between the interdecadal variation of sea-ice in Davis Strait and the atmospheric circulation is discussed by statistical analysis methods.

In this paper,the advanced microwave scanning radiometer(AMSR) data and the polynya signature simulation method(PSMM) are used to detect the sea ice in the Bohai Sea and to extract the sea ice edge information.

Through analysis of the 1999/2000 background field of winter circumfluence, we find that the changes of West Pacific subtropic high and polar vortex are important factors that affect the changes of winter climates characters of our countrys and decay or melt of sea ice in the Bohai Sea.

Based on the remote sensing data,information of the distribution of sea ice in the Bohai Sea was invariably vitiated by the illusory ice-pixel.

Based on the papers concerned on Bohai sea ice from Paper Databases of China Journal Net, this paper gives the state and tendency of Bohai sea ice research from.
