N2O Dynamics in the North Pacific Ocean and Bering Sea

在这个研究项目中，夏威夷大学的科学家们将研究海水中一氧化二氮（N2O）的生成速率，并确定生成速率与N2O释放到东热带北太平洋、亚北极太平洋和白令海上层大气中的关系。这些实验将确定在不同的海洋环境中产生N2O的微生物途径的相对重要性。这项研究将利用几个新的分析创新，以完善我们的N2O循环在热带北太平洋东部的理解，并扩大我们的知识N2O源和汇的亚北极太平洋和白令海。该研究小组将利用这一难得的机会，加入已经获得资助的研究巡航，探索海洋的大片区域，这些区域目前知之甚少，但在全球氮循环的运作中也具有非常重要的数量意义。

ABSTRACTOCE-0240787In this research project, scientists at the University of Hawaii will study the rate of nitrous oxide (N2O) formation in seawater and determine how production rate relates to the release of N2O to the overlying atmosphere in the eastern tropical North Pacific Ocean, the subarctic Pacific Ocean and in the Bering Sea. The experiments will identify the relative importance of the microbiological pathways by which N2O is produced in diverse marine environments. This study will take advantage of several new analytical innovations to refine our understanding of N2O cycling in the eastern tropical North Pacific and to extend our knowledge of N2O sources and sinks to the subarctic Pacific and the Bering Sea. The research team will take advantage of a rare opportunity to join already-funded research cruises to explore large regions of the ocean that are at once poorly understood but also very quantitatively significant in the workings of the global nitrogen cycle.
