It is estimated that a piece of organic debris  descends the ocean at about 100m per day.

据估计，每天有大约100米的有机碎片沉入海底。

By mapping the distribution of organic molecules in a rock, these tools could help scientists differentiate between organic debris from meteorite impacts and the remains of microbial life.

通过绘制岩石中有机分子的分布图，这些工具可以帮助科学家区分来自陨石撞击的有机碎片和微生物生命的遗迹。
