引言海冰对于人类在海上的活动影响是很大的。海面固定冰盖严重阻碍海上航行,海上浮冰威胁船舶的安全航行,甚至摧毁海上采油平台。海冰中的浮冰每天以10～20公里的速度移动。水道、冰穴、冰顶盖变化是很快的,可以说,海冰是地球表面上变化最快的固体。随着国民经济的发展,渤海湾油气资源的大力开发,对渤海冰情资料的要求越来越高;应用简单仪器进行目测是远跟不上用户的要求的。因此,对于我国具有冰面的海域进行调
INTRODUCTION Sea ice has a large impact on human activities at sea. Fixed ice sheets on the sea are a serious obstacle to maritime navigation. Sea ice floes threaten the safe navigation of ships and even destroy offshore oil platforms. The ice in the sea ice moves 10 to 20 kilometers per day. Watercourses, ice caves and ice caps are fast changing. It can be said that sea ice is the fastest-changing solid on the Earth’s surface. With the development of the national economy and the vigorous development of oil and gas resources in the Bohai Bay, the demands on the data of the ice sheet in the Bohai Sea are getting higher and higher. The use of simple instruments for visual inspection can not keep up with the requirements of users. Therefore, for our country with ice surface tune
