Abstract:

The Circum-Bohai-Sea Region is an important economic zone of China. The sea ice, which occurs at each winter, is the major marine hazard of the Bohai Sea. As a result, it is very important to evaluate the damage effects quantitatively in this region, which is seldom studied and analyzed systematically using long-time-series data. In this paper, the sea-ice disaster in the Bohai Sea is evaluated quantitatively based on the Sentinel-1 and GOCI. For different hazard-bearing bodies of the marine transportation and the offshore constructions, different sea-ice-hazard indexes are defined, which can be applied to analyze the sea-ice disaster quantitatively in the Bohai Sea, including the annual and inter-annual variations in the period from 2011 to 2017. The analysis results can provide the reference of the sea-ice monitoring in the Bohai Sea.
