Researchers will carry out investigations in the fields of atmospheric composition, water environment, sedimentary environment and the ecosystem at the South Pole.

研究人员将在南极进行大气组成、水环境、沉积环境和生态系统等方面的调查。

We know which sedimentary environments are more likely to preserve fossils.

我们知道哪些沉积环境更有可能保存化石。

So far, we've mostly been talking about sedimentary environments on land, but there are also sedimentary environments in the ocean.

到目前为止，我们主要谈论的是陆地上的沉积环境，但也有海洋中的沉积环境。

Naturally, most of the fossils that are preserved in marine sedimentary environments are marine animals, but are dinosaur fossils ever found in marine sediment?

当然，保存在海洋沉积环境中的大部分化石都是海洋动物，但是在海洋沉积物中是否发现过恐龙化石呢？
