A young newspaper reporter was sent to investigate how engineers and ecologists were fighting to keep migrating dunes from swallowing roads, bridges, and houses.

一位年轻的报纸记者被派去调查工程师和生态学家是如何努力阻止迁移的沙丘吞噬道路、桥梁和房屋的。

The flow of this " bottom current" creates migrating dunes, ripples and ribbon-shaped patterns in the sediment and mud along the ocean floor that have given scientists insights into its strength.

这种“海底暗流”的流动在海底的沉积物和泥浆中形成了迁移的沙丘、涟漪和带状图案，这让科学家们了解了它的强度。
