Water masses and circulation in the Eurasian Basin: Results from the Oden 91 expedition

摘要: The Oden 91 North Pole expedition obtained Oceanographic measurements on four sections in the Nansen and Amundsen basins of Eurasian Basin Makarov Canadian Basin, thereby proving feasibility carrying out a typical program using an icebreaker Arctic Ocean. data show greater spatial variability water structure circulation than was apparent from previous data. results that clear front exists between such upper halocline is almost absent Basin. lower produced Barents-Kara Sea region permeates much flows along continental slope into deeper strongly influenced by topography. Three return Atlantic layer are identified, one over Nansen-Gakkel Ridge, Lomonosov third flowing slight differences observed salinity temperature characteristics waters do not lead to obvious explanation their origin or flow pattern.
