Global mapping and monitoring of sea ice production

海冰形成过程中排出的咸水推动了全球颠覆的环流。我们开发了一种算法，首次根据卫星数据估计和提供全球海冰产量地图。通过系泊观测和算法的验证，揭示了沿海冰川的高结冰过程。我们已经揭示，达恩利角附近的区域是南极底水缺失的形成区，是南极洲第二高的产冰量。我们还澄清了南极海洋和鄂霍次克海海冰产量的变化与底层/中层水之间的强烈联系，并建议这些海洋的倾覆减弱。

Saline water rejected during sea ice formation drive the global overturning circulation. We have developed an algorithm to estimate and provide global mapping of sea ice production from satellite data for the first time. High ice production process in coastal polynyas has been clarified by mooring observations with validation of the algorithm. We have revealed that the region off Cape Darnley is the missing formation area of Antarctic Bottom Water with the second highest ice production in the Antarctica. We have also clarified the strong linkage between variabilities of sea ice production and bottom/intermediate water in the Antarctic Ocean and Okhotsk Sea and suggested weakening of the overturning in these oceans.
