| Abstract: | The German Antarctic scientific expedition did the investigation and got approximately 2.3G measured data of the sea ice in Weddell Sea during August to October in 2006.In this research paper,a total of 828 typical ice ridges were identified through our statistics;the height,width and angle of the ridge sails and keels were analyzed;and the morphology of ice ridge sails and keels was compared after the study area was parted into three regions.The angles of ridge sails and keels are close to normal distribut... |
