In this project, scientists from the State University of New York at Albany, Old Dominion University, and the University of Washington will participate in a series of cruises with scientists from the National Institute of Oceanography in Goa, India, to study nitrogen cycling in the water column of the Arabian Sea. Because of a spatially extensive and seasonally changing suboxic zone, the Arabian Sea is a region of major global significance for denitrification and nitrous oxide formation. This American contribution to the joint Indian-American effort would endeavor to (1) estimate the significance of the Arabian Sea in global denitrification, (2) determine how the rate of Arabian Sea water column denitrification varies spatially and temporally, (3) determine the relative importance of nitrification and denitrification in producing high effluxes of nitrous oxide from the Arabian Sea to the atmosphere.

在这一项目中，来自奥尔巴尼的纽约州立大学、旧自治领大学和华盛顿大学的科学家将与印度果阿国家海洋学研究所的科学家一起参加一系列航行，研究阿拉伯海水柱中的氮循环。 由于阿拉伯海的亚氧区面积广阔，且随季节变化，因此阿拉伯海是一个对反硝化和一氧化二氮形成具有全球重要意义的区域。 美国对印美联合努力的贡献将奋进于（1）估计阿拉伯海在全球反硝化作用中的重要性，（2）确定阿拉伯海水柱反硝化作用的速率如何在空间和时间上变化，（3）确定硝化和反硝化作用在产生从阿拉伯海到大气的高排放一氧化二氮中的相对重要性。
