Nutrient loading from watersheds to coastal waters leads to many effects on nature some of which are drastic enough to attract public attention such as with fin- or shellfish kills. Increased nutrient loading from anthropogenic sources has major impacts on the structure and function of shallow coastal ecosystems. To understand the processes driving nutrient flux in the land/sea margin ecosystems, it is necessary to determine how rates of nutrient loading from watersheds are coupled to the responses of the receiving system. Dr. Valiela and scientists from five other institutions will investigate the coupling in Waquoit Bay, Massachusetts. They will model and measure both the terrestrial and the aquatic components of the area in order to trace the effects of the nutrient supply on the Bay.

从分水岭到沿海水域的营养负荷对自然造成了许多影响，其中一些严重到足以引起公众的注意，例如鳍类或贝类死亡。人为来源的养分负荷增加对浅海生态系统的结构和功能有重大影响。为了了解陆地/海洋边缘生态系统中驱动养分流动的过程，有必要确定流域的养分负载率如何与接收系统的反应相关联。瓦列拉博士和来自其他五个机构的科学家将在马萨诸塞州的瓦科伊特湾调查这种耦合现象。他们将对该地区的陆地和水生成分进行建模和测量，以追踪营养物质供应对海湾的影响。
