项目摘要

This collaborative effort will make use of an extensive and unique data set collected over several years from the Chukchi Sea. Investigators from three institutions will study the interactions of physical, chemical, and biological processes of the Chukchi Sea ecosystem to define its present and perhaps future trophic status through a series of data and simulation analyses. The physical processes associated with biological and chemical processes in the Chukchi Sea will be assessed using data from a series of 13 current meter moorings in 1990-1991 and seven bilateral U.S.-U.S.S.R. cruises during 1988-1991. Work will be undertaken to analyze the buoyancy and current fields from the year-long time series data together with the wind field; to examine the role of physical processes, with a particular emphasis on the variability of the shelf circulation over the year, the role of the wind in forcing the shelf circulation, and the variable fluxes of heat, salt, and other dissolved substances through the system. The source water concentrations of nutrients will be combined with buoyancy flux estimates to calculate nutrient flux estimates. Nutrient budgets for the Chukchi Sea shelf will then be constructed and compared to subsurface oxygen inventories and primary production estimates. The work supports the goals and research priorities of the Arctic System Science (ARCSS) program of the Global Geosciences Initiative.

这一合作努力将利用广泛而独特的从楚科奇海收集了几年的数据。来自三个机构的研究人员将研究楚科奇海的物理、化学和生物过程生态系统，以确定其目前和未来的营养状态通过一系列的数据和模拟分析。物理与生物和化学过程相关的过程楚科奇海将使用一系列13个海流的数据进行评估。 1990年至1991年，美国和美国的7个双边系泊系统，苏联 1988年至1991年期间的巡航。将开展工作，分析浮力和流场从一年的时间序列数据与风场一起;检查物理的作用过程，特别强调年内陆架环流、风强迫作用大陆架环流，以及热、盐和其他溶解物质通过系统。水源水营养物的浓度将与浮力通量相结合估算，以计算养分通量估算值。养分收支楚科奇海大陆架将被建造并与地下氧气存量和初级生产估计。这项工作支持北极的目标和研究重点全球地球科学系统科学（ARCSS）倡议
