I go to the water when i want to feel the moors astern  


My work is dedicated to the observation of the large scale circulation of the oceans, through different methods and techniques. I started in the early days with ocean-atmosphere box models, followed by studies of the equatorial and southern Atlantic Ocean western boundary layer using inverse models, deep and intermediate circulation in the Gulf of Mexico using profiling floats and have nowadays a focus on the influence of the high latitudes on the global thermohaline conveyor belt. I have also interests in oceanographic instrumentation and took part in several research cruises to places like the Mediterranean Sea, Iceland or Newfoundland, were i Carried XBT, CTD, and Acoustic Doppler Current Profiler samplings.
 

Current reasearch includes:


Global inverse modelization of the oceanic circulation with detailed parametrization of processes in the southern ocean.
  • parametrization of the polynya role in the bottom water formation.
  • study of entrainment and diffusion processes, on the continental margins around Antarctica.
  • definition of improved air-sea flux, representing the net buoyancy loss of the ocean in the very southern latitudes.
  • direct measurements in the Weddell and Ross seas (current meters) and model results (BRIOS) are included.


ARGO project in the Southern Ocean: web site contributing to the ARGO Project in the Southern Ocean (http://argo.ocean.fsu.edu) and some other topics besides the monitoring of the Lagrangian profiling instruments:
  • mode water  formation and propagation in the high latitudes.
  • improvement of SST climatologies from float data .
  • interaction of floats with sea ice.
  • heat budget calculations in the mixed layer of the southeastern Indian Ocean.
