0137037 RossbyThis is a cooperative effort with the Bjerknes Center for Climate Research in Bergen, Norway to study the formation and structure of the Iceland-Faroes Front (IFF) and its continuation into the Norwegian Sea. This front delineates the boundary between the cold Arctic waters north and east of Iceland and the warm waters of the NE Atlantic. It is also a major supply route of warm saline water to the Nordic Seas. A Lagrangian study of the inflow of warm water along the IFF into the Norwegian Sea will be conducted using a total of 60 constant depth RAFOS floats. These will be deployed sequentially from Icelandic and Faroese research vessels at the southern entrance to the Iceland-Faroe ridge to determine from where the warm waters come, and continue their transit north across the ridge and beyond into the Norwegian Sea via the IFF. The Norwegian partners will study the spreading of the Arctic Intermediate Waters, an expanding water mass that appears to be displacing the Norwegian Deep Waters that overflow into the northeast Atlantic. The observations will be used together for detailed studies and syntheses of the circulation, and they will also be immensely valuable for the many modeling studies of the Nordic Seas circulation.

0137037 Rossby这是与挪威卑尔根比耶克内斯气候研究中心合作的成果，旨在研究冰岛-法罗群岛锋线 (IFF) 的形成和结构及其延伸到挪威海的情况。该锋线划定了冰岛北部和东部寒冷的北极水域与大西洋东北部温暖水域之间的边界。它也是向北欧海域供应温盐水的主要路线。将使用总共 60 个恒定深度的 RAFOS 浮标对温水沿 IFF 流入挪威海进行拉格朗日研究。这些研究船将从冰岛和法罗群岛的科考船上依次部署到冰岛-法罗海脊的南部入口，以确定温暖的海水来自何处，并继续向北穿过海脊，通过 IFF 进入挪威海。挪威合作伙伴将研究北极中层水域的扩张，这是一个不断扩大的水团，似乎正在取代溢出到东北大西洋的挪威深水。这些观测结果将被一起用于环流的详细研究和综合，它们对于北欧海洋环流的许多建模研究也将具有巨大的价值。
