ABSTRACTOPP-9815808 OPP-9815497DUNTON, KENNETH GREBMEIER, JACQUELINEUNIVERSITY OF TEXAS UNIVERSITY OF TENNESSEEThis project will utilize existing data sets on the biomass, density, and composition of benthic organisms in the Chukchi and Beaufort Seas as an indicator of the patterns of sinking organic matter that provides the energy to sustain the benthic community. In addition to the biologic data sets, physical properties of the water column, sediments, and sea ice will be used as environmental variables controlling distribution patterns. Geographic Information System (GIS) software will be used to examine and graphically display relationships between predominant physical forcing processes and ecosystem productivity. The resulting data set will allow examination of the effects of changing climate conditions on the distribution of biologic productivity patterns in the Arctic Ocean. The results of this project will provide input for planning a large Phase 2 field program of the Shelf Basin Interactions project in 2002.

摘要-9815808 DUNTON，KENNETH 该项目将利用楚科奇海和博福特海底栖生物量、密度和组成的现有数据集，作为提供维持底栖生物群落能量的下沉有机物模式的指标。 除了生物数据集之外，水柱、沉积物和海冰的物理特性也将被用作控制分布模式的环境变量。 将使用地理信息系统软件来审查和以图形显示主要物理强迫过程与生态系统生产力之间的关系。 由此产生的数据集将有助于研究气候条件变化对北冰洋生物生产力格局分布的影响。 该项目的结果将为2002年陆架盆地相互作用项目第二阶段大型现场方案的规划提供投入。
