Remote Sensing of Sea Ice Thickness: A Proposal to Participate in the 1991 Antarctic Winter Cruise of the POLARSTERN

极地海冰覆盖的厚度是一个重要的参数， 大气和海洋之间的能量交换， 作为全球气候变化的重要变量。 目前用于确定冰厚度的方法是如此低效， 需要采用遥感技术， 然而，到目前为止，还没有可行的方法来进行测量， 目前的研究计划将尝试一种新技术 它观察超高频（UHF）的加权平均值， 海冰和底层水面的微波辐射。 的 从美国宇航局兰利研究中心借来的UHF辐射计有一个 理论上可以测量一米厚的海冰， 超过了未变形的第一年冰层的平均厚度， 南极洲

The thickness of the polar sea ice cover is an important parameter in the exchange of energy between the atmosphere and the ocean, and may act as a significant variable in the variation of the global climate. Present methods for determining the ice thickness are so inefficient and labor-intensive that remote sensing techniques need to be introduced, however up to this time no feasible way to make the measurements has been found. The present research program will try out a new technique which observes the weighted average of the ultra-high frequency (UHF) microwave emission of the sea ice and the underlying water surface. The UHF radiometer, on loan from the NASA Langley Research Center has a theoretical capability to measure sea ice thickness up to one meter, which exceeds the average thickness of undeformed first-year ice around Antarctica.
