Determining the Stable Isotope Signatures of N2O in the Coastal Environments

确定沿海环境中N2O的稳定同位素特征本研究将通过利用由资助的实验提供的后勤机会来研究海洋氧化亚氮（N2O）的状况，该实验将研究英国缺氧水域的氮循环热带太平洋东部具体地说，N2O的双稳定同位素组成将被添加到将由dr。a . Devol和P. Quay，大陆边缘沉积物底栖碳氧化、反硝化和氮同位素分馏项目（OCE 9116275）。额外的工作将利用最近开发的一项技术，该技术允许从小样本中确定N2O的双同位素组成。还将测量东热带太平洋缺氧水柱中一氧化二氮的浓度。

Determining the Stable Isotope Signatures of N2O In The Coastal Environments This Study will investigate the marine nitrous oxide (N2O) regime by taking advantage of the logistic opportunities provided by a funded experiment that will investigate nitrogen cycling in the suboxic waters of the eastern tropical Pacific Ocean. Specifically, the dual stable isotopic composition of N2O will be added to the suite of measurements that will be undertaken by Drs. A. Devol and P. Quay under a project entitled "Benthic carbon oxidation, denitrification and nitrogen isotope fractionation in continental margin sediments (OCE 9116275). The additional work will take advantage of a recently developed technique that permits the dual isotope composition of N2O to be determined from small samples. Measurements of the concentration of N2O in the suboxic water column of the eastern tropic Pacific Ocean will also be done.
