    • 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 ...

    • Turbulent upper-ocean mixing affected by meltwater layers during Arctic summer 

      Randelhoff, Achim; Fer, Ilker; Sundfjord, Arild (American Meteorological Society, 2017-04)
      Every summer, intense sea ice melt around the margins of the Arctic pack ice leads to a stratified surface layer, potentially without a traditional surface mixed layer. The associated strengthening of near-surface ...
