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罗斯比这是一项与挪威卑尔根的比耶克内斯气候研究中心合作的工作，目的是研究冰岛-法罗斯锋的形成和结构以及它进入挪威海的过程。这条锋面划定了冰岛以北和以东寒冷的北极水域和东北大西洋温暖水域之间的边界。它也是北欧海域温盐水的主要供应路线。将使用总共60个恒定深度的RAFOS浮标，对沿IFF流入挪威海的暖水进行拉格朗日研究。这些设备将从冰岛-法罗海脊南部入口处的冰岛和法罗考察船上依次部署，以确定温暖海水的来源，并继续向北穿过海脊，通过论坛进入挪威海。挪威的合作伙伴将研究北极中间水域的扩散，这种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。这些观测将一起用于环流的详细研究和合成，它们也将对北欧海洋环流的许多模拟研究具有极大的价值。
