他们可以追踪大陆冰川的生长和收缩，即使是在温度变化不大的海洋区域——比如，赤道附近。

They could trace the growth and shrinkage of continental glaciers, even in parts of the ocean where there may have been no great change in temperature—around the equator, for example.

即使潮波在赤道上移动的速度跟得上月亮，海洋深度必须为22公里左右。

In order for the tide waves to move fast enough at the equator to keep up with the moon, the ocean would have to be about 22km deep.
