Excessive nutrient release from manmade sources may lead to algal blooms in aquatic environments. Nitrogen is a nutrient of particular concern in coastal waters because it controls algal growth. Aquatic environments are able to cleanse themselves of excess nitrogen by a process known as denitrification which happens in the sediments. Amazingly, we have no understanding of how denitrification works in sands despite the fact that most of the coastline is covered in sand. The results from this project will provide critical information needed to predict and reduce algal blooms in coastal waters.

从人为来源释放过多的营养物质可能导致水生环境中的藻华。在沿海水域，氮是一种特别值得关注的营养物，因为它控制着藻类的生长。水生环境能够通过发生在沉积物中的反硝化过程来净化自己多余的氮。令人惊讶的是，尽管大部分海岸线都被沙子覆盖，但我们对沙子中的反硝化作用是如何起作用的却一无所知。该项目的结果将提供预测和减少沿海水域藻华所需的关键信息。
