ABSTRACTOCE-0444316OCE-0446987With support through the NSF Small Grants for Exploratory Research Program, researchers from the University of Miami and the University of California at Santa Barbara will study the regional and depth distribution of dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) in the Atlantic Ocean. To collect seawater samples from the surface to the deep ocean along a north-south cruise transect of the Atlantic Ocean for chemical analysis, they will take advantage of an invitation to participate in U.S. Repeat Hydrographic Survey of the Atlantic basin in 2005. Because such data are sparse for this region of the world ocean, the investigators anticipate that the new information gathered will significantly improve our understanding of the oceanic distribution of DOC/DON and, as a broader impact, of the role played by these substances in global carbon cycling and climatic change.

在美国国家科学基金会探索性研究计划小额赠款的支持下，来自迈阿密大学和加州大学圣巴巴拉分校的研究人员将研究大西洋溶解有机碳（DOC）和溶解有机氮（DON）的区域和深度分布。 为了沿着大西洋南北巡航样带从表层到深海收集海水样本进行化学分析，他们将利用参加2005年美国大西洋盆地重复水文调查的邀请。 由于这些数据在世界海洋的这一地区很少，研究人员预计，收集的新信息将大大提高我们对DOC/DON海洋分布的理解，并作为更广泛的影响，这些物质在全球碳循环和气候变化中所发挥的作用。
