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.
