    • Mass balance of Nyainqen Tanglha glacier, Tibet, 1977 to 2001, derived by topographical maps and satellite images 

      Dong, Cai (The University of Bergen, 2004)
      NyainQen TangLha Glacier plays an important role in the Tibetan plateau’s climate system. Because of high altitude, steeply sloping terrain and difficult access, regular, systematic surveys of glacial variation are almost ...

    • Measured volume, heat, and salt fluxes from the Atlantic to the Arctic Mediterranean 

      Østerhus, Svein; Turrell, William R.; Jónsson, Steingrímur; Hansen, Bogi (American Geophysical Union, 2005-04-07)
      The flow of warm and saline Atlantic water towards the Arctic crosses the Greenland-Scotland Ridge in three current branches. Since the mid 1990's, extensive monitoring with quasi-permanent moorings and regular CTD cruises ...

    • A mechanical energy budget for the North Sea 

      Barthel, Knut; Gade, Herman G.; Sandal, Cathrine K. (Pergamon, 2004-06-29)
      A three-dimensional baroclinic numerical model is used to quantify the components of the mechanical energy budget for a semi-enclosed sea, the North Sea. As anticipated, tidal energy is the largest supplier of mechanical ...
