  Response of a Strongly Eddying Global Ocean to North Atlantic
  Freshwater Perturbations

  The Atlantic ocean circulation, in particular its Meridional
  Overturning Circulation (MOC), is sensitive to the surface
  freshwater flux. In this presentation we show results on the
  differences between the (decadal time scale) response of a
  coarse-resolution (non-eddying) global ocean model and a
  fine-resolution (strongly eddying) version of the same model to
  a (relatively large) freshwater perturbation due to melting of
  the Greenland Ice Sheet. We focus on the effect of the
  freshwater anomaly on convection, watermass transformations
  and the basin wide circulation.

  Henk A. Dijkstra is professor of Dynamical Oceanography at the
  Institute for Marine
  and Atmospheric research Utrecht (IMAU) within  the Department of
  Physics and Astronomy
  of Utrecht University,  the Netherlands. After graduating in applied
  mathematics at the
  University of Groningen in 1984, he worked during his Ph.D. (in
  Groningen) on a Spacelab
  experiment involving Marangoni convection under  microgravity
  conditions. He continued with
  this research at the Department of  Chemical  Engineering at Cornell
  University during the
  period 1988-1990. Since 1990 he works at Utrecht University mainly on
  the  stability of the
  ocean circulation and on the physics of climate variability.  He is
  author of the books
  "Nonlinear   Physical Oceanography" (Springer,  2e edition  2005),
  "Dynamical  Oceanography"
  (Springer,  2008) and "Nonlinear Climate  Dynamics"  (Cambridge
  University Press, 2013).
  Since 2002, he is a member of the Dutch Royal Academy  of Arts  and
  Sciences (KNAW). In
  2005, he received the Lewis Fry Richardson medal from  the  European
  Geosciences Union
  and in 2009 he  was elected a Fellow of the Society for Industrial and 
Applied
  Mathematics (SIAM).
