This award supports cooperative research on three aspects of the marine nitrogen cycle between scientists at Lamont-Doherty Geological Observatory and Dr. K.K. Liu from the Institute of Earth Sciences, Taiwan. The biogeochemical cycle of nitrogen in the environment is one of the most important but least understood topics in the earth sciences. The marine nitrogen cycle is probably more complex than other biologically essential elements. This study will focus on the controlling factors of nitrogen isotopic composition of dissolved and pareticulate nitrogen species; the isotopic imprint of nitrogen fixers; and isotopic records in the sedimentary column. This research will involve contributions by an isotopic geochemist, a geochemist, and a biological oceanographer. The project is jointly sponsored by NSF and the National Science Council of Taiwan.

该奖项支持拉蒙特-多尔蒂地质观测站的科学家和台湾地球科学研究所的刘锦坤博士就海洋氮循环的三个方面进行的合作研究。环境中氮的生物地球化学循环是地球科学中最重要但了解最少的主题之一。海洋氮循环可能比其他生物必需元素更复杂。这项研究将集中于溶解和颗粒状氮的氮同位素组成的控制因素，固氮剂的同位素印迹，以及沉积柱中的同位素记录。这项研究将包括一名同位素地球化学家、一名地球化学家和一名生物海洋学家的贡献。该项目由美国国家科学基金会和台湾国家科学委员会联合发起。
