Molecular and Isotopic Tracers of Marine Production and Its Fate in the Western Arctic Ocean

这个项目将利用波弗特海的现有样本来确定北冰洋中的有机物是否可以通过“指纹”来揭示其来源。如果是这样，就可以估计其分布格局，并评估支持初级生产的有机物的可得性。该项目对于了解碳在大陆架和深盆地之间运输并进入沉积物的方式非常重要。这些结果对于分析沉积物中的有机物作为盆地生物生产历史的线索也很重要。沉积记录可以揭示因气候变化而发生的变化。该项目的结果将为规划2002年在同一地理区域的陆架盆地相互作用项目的大型第2阶段实地方案提供投入。

ABSTRACTOPP-9815725HARVEY, RODGERUNIVERSITY OF MARYLANDThis project will utilize existing samples in the Beaufort Sea to determine if the organic matter in the Arctic Ocean can be "fingerprinted" to reveal its source. If so, the distribution patterns may be estimated and the availability of the organic matter for support of primary production may be assessed. The project is very important to understanding the way carbon is transported between the continental shelf and deep basin and into the sediment. The results will also be important for analysis of organic matter in the sediment as a clue to the history of biogenic production in the basin. The sedimentary record could reveal changes that have occurred in response to climate change. The results of this project will provide input for planning a large Phase 2 field program of the Shelf Basin Interactions project in 2002 in the same geographic area.
