Wingham said that, without CryoSat-2, there would be a significant gap in the data needed to track climate change.

温厄姆说，如果没有克里赛特-2的协助，在跟踪气候变化所必需的数据方面就会出现巨大的空白。

If the measurements from CryoSat-2 bear out this thinning theory, it would mean the ice is being lost more quickly.

如果来自克里赛特- 2的测量数值证实了薄化理论是正确的，就表明冰层融解正在加快。

He adds that the data gathered during the expedition will also be used to calibrate the instruments on Esa's Cryosat-2 satellite, scheduled to be launched in 2009.

Although built mainly in Germany and France, CryoSat-2 is led scientifically from the UK by its proposer and principal investigator, Professor Duncan Wingham from University College London.
