  • 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 ...
  • Dissolution from a liquid CO2 lake disposed in the deep ocean 

    Fer, Ilker; Haugan, Peter Mosby (American Society of Limnology and Oceanography, 2003)
    The dissolution from a liquid CO2 lake source located at a flat ocean bottom at 3,000 m depth is investigated. Using the unsteady, two-dimensional advection–diffusion equation, temporal and spatial distribution of CO2 ...
  • Dynamics of a CO2-seawater interface in the deep ocean 

    Hove, Joakim; Haugan, Peter Mosby (Sears Foundation for Marine Research, 2005)
    A trough filled with liquid CO2 located at 3940 m depth has been used as a model system for CO2 deposition on the seafloor. To study the intrinsic properties of the interface between CO2 and seawater a wave maker was used ...
  • Flow over a backward-facing step, a numerical study comparing a zand a σ-coordinate model 

    Rygg, Kristin; Alendal, Guttorm; Haugan, Peter Mosby (Springer Verlag, 2011)
    Homogeneous, nonrotating flow over a backward-facing rounded step is simulated using the 2D vertical version of two general circulation models, a z-coordinate model—the Massachusetts Institute of Technology general ...
  • Metrics to assess the mitigation of global warming by carbon capture and storage in the ocean and in geological reservoirs 

    Haugan, Peter Mosby; Joos, Fortunat (American Geophysical Union, 2004-09-18)
    Different metrics to assess mitigation of global warming by carbon capture and storage are discussed. The climatic impact of capturing 30% of the anthropogenic carbon emission and its storage in the ocean or in ...
  • Microwave Study programs of Air-Ice-Ocean interactive processes in the Seasonal Ice Zone of the Greenland and Barents Seas 

    Johannessen, Ola M.; Campbell, William J.; Shuchman, Robert A.; Sandven, Stein; Gloersen, Per; Johannessen, Johnny A.; Josberger, Edward G.; Haugan, Peter Mosby (American Geophysical Union, 1992)
    Describes the use of satellite ice data into a working technology for the satellite data sets of the recent past and immediate future. Chapters cover basic observations, modeling, geophysical interpretation, and using data ...
  • Mixing of the Storfjorden overflow (Svalbard Archipelago) inferred from denstity overturns 

    Fer, Ilker; Skogseth, Ragnheid; Haugan, Peter Mosby (American Geophysical Union, 2004-01-03)
    Observations were made of the dense overflow from Storfjorden from a survey conducted at closely spaced stations in August 2002. The field data set consists of conventional conductivity-temperature-depth profiles and ...
  • Modelling of deep-sea gravity currents using an integrated plume model 

    Alendal, Guttorm; Drange, Helge; Haugan, Peter Mosby (American Geophysical Union, 1994)
  • A numerical study of transport and spreading of gases from natural analogues of gas-seepage through the seafloor 

    Enstad, Lars Inge; Alendal, Guttorm; Haugan, Peter Mosby (Elsevier, 2009-02)
    Natural leakages of CO2 are reported in the literature at mid ocean ridges and CH4 seepages in hydrocarbon rich ares. These could potentially serve as natural analogues of leakages from CO2 storages. In this study we have ...
  • Observations of the Storfjorden overflow 

    Fer, Ilker; Skogseth, Ragnheid; Haugan, Peter Mosby (Elsevier, 2003)
    The mixing and spreading of the Storfjorden overflow were investigated with density and horizontal velocity profiles collected at closely spaced stations. The dense bottom water generated by strong winter cooling, enhanced ...
  • Ocean abyssal carbon experiments at 0.7 and 4 km depth 

    Haugan, Peter Mosby; Brewer, Peter G.; Peltzer, Edward T.; Walz, Peter; Aya, Izuo; Yamane, Kenji; Kojima, Ryuji; Nakajima, Yasuharu; Nakayama, Noriko; Hove, Joakim; Johannessen, Truls; Bellerby, Richard G. J.; Alendal, Guttorm (Elsevier, 2005)
    Observations from small-scale (20 to 90 litres) CO2 experiments conducted off the coast of California at 684 m depth and at 3942 m depth are discussed. In both experiments, when the seawater velocity was sufficiently strong, ...
  • Ocean storage 

    Caldeira, Ken; Akai, Makoto; Brewer, Peter G.; Chen, Baixin; Haugan, Peter Mosby; Iwama, Toru; Johnston, Paul; Kheshgi, Haroon; Li, Qingquan; Ohsumi, Takashi; Pörtner, Hans; Sabine, Chris; Shirayama, Yoshihisa; Thomson, Jolyon (Intergovermental Panel on Climate Change, 2005)
  • Parameterization of drag and dissolution of rising CO2 drops in seawater 

    Gangstø, Reidun; Haugan, Peter Mosby; Alendal, Guttorm (American Geophysical Union, 2005-05-24)
    In this work the dynamics and dissolution of a hydratecovered CO2 drop were studied, using a numeric model and data from one of very few CO2 experiments performed in the real ocean. A theory including the standard drag ...
  • Topographic effects on CO2, diffusion and dissolution from the seafloor 

    Rygg, Kristin; Enstad, Lars Inge; Alendal, Guttorm; Haugan, Peter Mosby (Elsevier, 2009-02)
    At 3000 meters depth liquid CO2 is denser than seawater and hence will be stored as a “lake” on the deep ocean floor, which is expected to gradually be dissolved in seawater. Ocean currents and turbulence will influence ...
  • Turbulent diffusion and transport from a CO2 lake in the deep ocean 

    Haugan, Peter Mosby; Alendal, Guttorm (American Geophysical Union, 2005-09-21)
    If liquid CO2 is stored as a dense ‘‘lake’’ on the deep ocean floor, it is expected to dissolve in seawater. Ocean currents and turbulence can increase the net rate of CO2 release by several orders of magnitude compared ...
