Abstract: To discover water sources of agriculture irrigation for regions around Bohai Sea in China, sea ice in Bohai Sea is considered as a new kind of fresh water resource due to its lower salinity than seawater, and it is feasible after many experiments. So it is vital to know the quantity of the sea ice in Bohai Sea. Thickness is one of the most important parameters to estimate the quantity of sea ice. There are many methods to calculate the sea ice thickness. Remote sensing is one of the most feasible methods because of the high-temporal and multiple spatial resolutions. Then an appropriate method should be used to calculate the sea ice thickness based on Remote Sensing. This paper comes up with a method to calculate the sea ice thickness based on the solar shortwave radiation theories. Using the methods above, this paper comes up with the time series of sea ice thickness from 1987 to 2007. The thickness time series are important to the sea ice resources calculation. And the thickness time series are also an indication of climate change. It is an evidence of global warming according to the variation of the sea ice thickness or sea ice resources.
