Paper Abstract

During the winter in later 2009 and early 2010, the Bohai Sea experienced its worst sea ice event in four decades. Sea ice optical properties are derived from MODIS-Aqua measurements using the SWIR atmospheric correction algorithm. The radiance feature of the sea ice in the Bohai Sea shows a strong dependence on ice types. For months of December, January, and February during the winter of 2009-2010, the average sea ice albedo in the Bohai Sea reached about 9.3%, 13.4%, and 12.6%, respectively. A regional sea ice detection algorithm has been developed for monitoring sea ice in the Bohai Sea. During the 2009- 2010 winter, the sea ice covered about 5427, 27414, and 21156 km2 for the three winter months, while average values of sea ice coverage between 2002-2010 are about 2735, 11119, and 10287 km2, respectively. Anomalously large sea ice event in the Bohai Sea during 2009-2010 winter is attributed to the dominance of a high air pressure system in the northern China and widespread air temperature drops in January and early February of 2010.
