我们报道了日本东北部俯冲带水进入深部地幔的地震证据。我们的数据表明，水在浅层(小于或类似于100公里)从水化的洋壳中释放出来，然后在俯冲板块顶部形成一个水化地幔物质通道，这是水进入地幔深处的通道。我们的结果提供了直接的证据，表明在寒冷的俯冲带环境中，水是如何从海洋输送到地幔深处的。
We report seismic evidence for the transportation of water into the deep mantle in the subduction zone beneath northeastern Japan. Our data indicate that water is released from the hydrated oceanic crust at shallow depths (less than or similar to 100 kilometers) and then forms a channel of hydrated mantle material on top of the subducting plate that is the pathway for water into the deep mantle. Our result provides direct evidence that shows how water is transported from the ocean to the deep mantle in a cold subduction zone environment.
