A Lagrangian Study of the Iceland-Faroe Front, a Major Link Between the North Atlantic and Nordic Seas

这是与挪威卑尔根的比耶克内斯气候研究中心的合作项目，旨在研究冰岛-法罗锋面（IFF）的形成和结构及其进入挪威海的延续。这个锋面划定了冰岛北部和东部寒冷的北极水域和东北大西洋温暖水域之间的边界。它也是向北欧海输送温盐水的主要路线。将使用总共60个定深RAFOS浮标对沿IFF流入挪威海的温水进行拉格朗日研究。这些设备将依次从冰岛和法罗岛的研究船上部署到冰岛-法罗海岭的南部入口，以确定温暖的海水从哪里来，并继续向北穿越海岭，通过IFF进入挪威海。挪威的合作伙伴将研究北极中间水域的扩张，这是一片不断扩大的水域，似乎正在取代流入东北大西洋的挪威深水。这些观测结果将一起用于详细研究和综合环流，它们对北欧海环流的许多模拟研究也将非常有价值。

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.
