Drift Ice in the Liaodong Wan, China in 1983, '84, ' 85 and '86

Abstract

Some features of drift ice in the Liaodong Wan (bay) are described by using the Landsat images. Drift ice is able to see every year for four winter seasons in this bay since 1982. The extent and state or stage of sea ice, numbers and sizes of floe are seen on the images. The changes of forms of drift ice and ice fields are observed by comparing sequential images.
They say the southern limit of the drift ice is 44^° N at the southern part of the Okhotsk Sea in the northern hemisphere. However it is not 44^°N but 38' 30'N or more southern part in the Liaodong Wan and Bohai. Sea ice is seen till 37^°10' in the Bohai.
The reason why the ports of Dalian and Lushun do not freeze is also mentioned.
