The Outflow of Fresh Water from the Canadian Archipelago: Synoptic Currents, Hydrography, and Long Term Forcing

该项目将利用加拿大海岸警卫队的破冰船从巴芬湾开始，通过加拿大群岛，到波弗特海进行一系列的海洋学横断面，在那里将进行一个大型的多学科研究项目，北极海洋表面热收支（SHEBA）。一个示踪剂浓度的测量项目将用于追踪从北冰洋流出的淡水，这些淡水流经加拿大群岛的一系列出口。外流气流的强度和体积将在控制环流的物理和大气动力学框架内确定。该项目将通过全球管道系统中研究最少的“阀门”之一，为了解北冰洋与全球海洋之间的联系的全球变化增加一个重要组成部分。

ABSTRACT OPP-9708349 MUNCHOW, ANDREAS RUTGERS UNIVERSITY This project will utilize a Canadian Coast Guard icebreaker to conduct a series of oceanographic transects from Baffin Bay, through the Canadian archipelago, to the Beaufort Sea where a large, multidisciplinary research program, Surface Heat Budget of the Arctic (SHEBA) Ocean, will be conducted. A measurement program of tracer concentrations will be used to track fresh water flow out of the Arctic Ocean through a series of outlets in the Canadian Archipelago. The strength and volume of the outflow will be determined within a framework of physical and atmospheric dynamics that control the circulation. This project will add an important component to the understanding of global change on linkages of the Arctic Ocean to the global ocean through one of the least studied "valves" in the global plumbing system.
