The next day, April 1, when the Nautilus rose to the surface of the waves a few minutes before noon, we raised land to the west.

第二天，4月1日，诺第留斯号浮上水面来。中午前几分钟，我们在西面望见了海岸。

This involves injecting cement into soft or contaminated soil - stabilising it and removing the need for environmentally damaging dredging to take place - before more material is added to raise the land above sea level.

这涉及将水泥注入松软或受污染的土壤中——使其稳定并消除对环境造成破坏的疏浚的需要——然后再添加更多材料以将土地抬高至海平面以上。
