    • Decadal solar irradiance variability in northern Europe 

      Parding, Kajsa (The University of Bergen, 2014-11-28)
      Shortwave (SW) radiation from the Sun is the external energy source on Earth and the fundamental input of energy into the climate system. Variations of the SW radiation and its transfer through the atmosphere can have ...

    • Deep ocean experiments with fossil fuel carbon dioxide: creation and sensing of a controlled plume at 4 km depth 

      Brewer, Peter G.; Peltzer, Edward T.; Walz, Peter; Aya, Izuo; Yamane, Kenji; Kojima, Ryuji; Nakajima, Yasuharu; Nakayama, Noriko; Haugan, Peter Mosby; Johannessen, Truls (Sears Foundation for Marine Research, 2005-01)
      The rapidly rising levels of atmospheric and oceanic CO2 from the burning of fossil fuels has lead to well-established international concerns over dangerous anthropogenic interference with climate. Disposal of captured ...

    • The deepening of the Atlantic water in the Lofoten Basin of the Norwegian Sea, demonstrated by using an active reduced gravity model 

      Orvik, Kjell Arild (American Geophysical Union, 2004-06-29)
      The Norwegian Atlantic Current (NwAC) as a poleward eastern boundary current is to be considered as the northern limb of the Meridional Overturning Circulation in the North Atlantic (MOC). It transports warm and saline ...
