Configuration of an Ecosystem Model for the Chukchi Sea Using Data from 1994-1996

本项目将利用1994年美国-加拿大联合北冰洋巡航所收集的生物数据，验证楚科奇海的生态系统模型。该模型将侧重于海洋生物在生态系统中的作用。研究结果将用于研究从大陆架向深盆地输出的无机营养物、微粒和溶解的有机物质。通过了解调节大陆架生物过程的因素，该模型将有助于预测气候等物理参数变化对大陆架生产的规模和命运以及大陆架与盆地之间营养物质交换的影响。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-9815252WHEELER, PATRICIAOREGON STATE UNIVERSITYThis project will use biologic data collected in 1994 on the joint US-Canadian Arctic Ocean Section cruise in the Arctic Ocean to verify an ecosystem model for the Chukchi Sea. The model will focus on the role of pelagic organisms in the ecosystem. The results will be used to examine the export of inorganic nutrients, particulate and dissolved organic matter from the continental shelf into the deep basin. By understanding the factors that regulate biological processes on the shelf, the model will facilitate prediction of the effects of changes in physical parameters such as climate on the magnitude and fate of shelf production and exchange of nutrients between shelf and basin. 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.
