Ocean sediments presented a much more complete geologic record of the Pleistocene than continental glacial deposits did.

相比于大陆冰川沉积物，海洋沉积物提供了更完整的更新世时期的地质记录。

As geologists mapped glacial deposits in the late nineteenth century, they became aware that there were several layers of drift, the lower ones corresponding to earlier ice ages.

19世纪晚期，在地质学家对这些冰川沉积进行定位的时候，他们意识到有好几个漂流层，位置较低的对应的是更早的冰川期。

The results indicate that glacial deposits have a nice character of self-comparability in statistics.

冰川堆积物的粒度组成、砾石形态和排列特征都有很好的分形特征。

But what we're finding is that a significant amount may have been sequestered in glacial deposits.

So some of the water is being taken out of the system, not by being lost from the planet, but by being sequestered - or hidden away - in these glacial deposits.
