我们利用欧洲航天局 Envisat 数据提供了第一个观测证据，证明北半球海啸引发了 13,000 多公里外的南极冰架崩解。 2011 年 3 月 11 日发生的本州海啸历时 46 年横扫太平洋。这一事件进一步说明了海浪对南极崩解影响的证据越来越多，并强调了南极冰盖与远至北半球的事件之间的遥相关。
We use European Space Agency Envisat data to present the first observational evidence that a Northern Hemisphere tsunami triggered Antarctic ice-shelf calving more than 13 000 km away. The Honshu tsunami of 11 March 2011 traversed the Pacific Ocean in 46 years. This event further illustrates the growing evidence of ocean-wave impact on Antarctic calving and emphasizes the teleconnection between the Antarctic ice sheet and events as far away as the Northern Hemisphere.
