现场冰厚测量原理及应用技术分析

Field test of sea-ice thickness measurement principle and its application analysis

海冰主要是指飘浮在海面上的冰块,它们受风和流的作用而产生运动,其推力与冰块的大小和流速有关。海冰不仅被认为是一种严重的自然灾害,同时在寒冰海域的资源开发利用当中,海冰的物理参数也被认为是重要的环境参数,其中海冰厚度最为重要。为了监视和研究海冰厚度的生消变化,人们采取了很多方法来获取海冰厚度。本文综述了近几十年来国内外具有代表性的测量海冰厚度的方法,并对每种方法的测量误差进行了分析。

The sea-ice mainly refers to that floats on the surface of the sea.They are affected by the wind and the flow.Sea-ice is considered to be not only a kind of serious natural disaster,at the same time in the icy water of resources development,the physical parameters of the sea ice is also considered an important environmental parameters that the sea-ice thickness is the most important.In order to monitor and study the sea-ice thickness change and disappear,people have taken a lot of methods to obtain the thickness of the ice.This paper summarizes the method of measuring ice thickness representative at home and abroad in recent years.There is also the error analysis about each method.
