摘要：

基于2003年7月至9月中国第二次北极科学考察所获取的大量海冰影像资料,完成了走航期间74.11°N—79.56°N,144.17°W—169.95°W范围内海冰厚度和密集度的提取。本文总结了从船侧录像中提取冰/雪厚度以及从航拍图像中提取冰密集度的方法,并描述了提高所取参数可靠性应采取的分析技术和现场调查的处理措施。本文方法具有一定的普适性,可以应用到渤海海冰和极地海冰的研究中。

Abstract:

Based on the sea ice digital videos and photos along the investigation route in the Second Chinese National Arctic Research Expedition (CHINARE) during July and September, 2003, collections of sea ice thickness and concentration in the area of latitude range of 74.11°N—79.56°N and longitude range of 144.17°W—169.95°W are finished. This paper discusses the methods of obtaining ice/snow thicknesses from ship-side videos and ice concentrations from aerial photos, and illustrates the measures should be taken in analysis and in-situ investigation processes to improve the reliability of the parameters. The methods in this paper are somewhat universal and can be used in the research of Bohai Sea and polar sea ice.
