Nitrogen Cycling in the Upper Ocean of an Oligotrophic Gyre

McCarthy博士和Bigelow实验室的Garside博士合作。将研究马尾藻海北部的氮循环、颗粒物和硝酸盐同位素特征。研究人员将使用化学发光硝酸盐技术和改进的铵分析来提供迄今为止最灵敏的贫营养水域氮循环分析。氮是一种植物养分，被认为限制了世界大部分海洋的生物生产力。通过应用本工作中应用的最先进技术，贫营养海洋中氮循环的问题将得到推进。

Dr. McCarthy in collaboration with Dr. Garside of Bigelow Lab. will study nitrogen cycling and particulate matter and nitrate isotopic signature in the northern Sargasso Sea. The researchers will use the chemoluminescent nitrate technique and improved ammonium analysis to provide the most sensitive analysis to date of nitrogen cycling in oligotrophic waters. Nitrogen is a plant nutrient that is thought to limit biological productivity in much of the world ocean. The question of nitrogen cycling in oligotrophic oceans will be advanced by the application of the state of the art techniques applied in this work.
