The researchers looked at sediments from Lake Bosumtwi spanning about the last 3,000 years."Lake Bosumtwi is really unique in that its one of the few locations in tropical West Africa where varves, annual sediment layers, are preserved. This allows us to look at changes in climate at very high resolution," said Shanahan.

The subsoils in which the tunnels are buried are young sediments and are very weak in strength.

因所处地层多属软弱粘土层，故以地盘改良为稳定地层辅助工法。

The spherules, which the team called blueberries, showed clear signs of having been built up layer by layer within sediments, just like the pearls in our oceans.

I think these sediments are merely a pile of loose and unconsolidated particles. How are they converted into solidated hard strata?

但是这些沉积物仅仅是一堆松散的，未固结的颗粒物质，它们是怎么变成固结和坚硬的岩石的呢？

A recent discovery makes such a determination possible: relative land-ice volume for a given period can be deduced from the ratio of two oxygen isotopes, 16 and 18, found in ocean sediments.

最近的一个发现使得这样的测定变得可行：过去某一时期相对陆地冰的数量可以从两种氧同位素，氧16和氧18的比例中推算出，这两种同位素发现于海洋沉积物中。
