Estimation of the ventilation in the Bay of Biscay in 2009-2012 using oxygen profiles from argo data.  ÁLVAREZ, RUIZ-VILLARREAL, GONZÁLEZ-POLA, LAVÍNThree argo floats equipped with SBE43 oxygen sensors were deployed in the center of the Bay of Biscay in September 2010 during the RADPROF cruise. Winkler oxygen measurements were also taken for calibration. A few weeks later two sensors failed. We present the remaining argo oxygen data from September 2010 to August 2012 covering from center of the Bay of Biscay to 15ºW in the North-East Atlantic. We caught two episodes of winter convection where the upper 400 meter were homogenized in temperature and salinity and took a deep breath in oxygen. A winter shallow oxygen maximum was developed. We will try to elucidate the mechanisms behind its formation. Sea surface layer altimetry data will be used to study the trajectory of the floats in relation with surface currents. The seasonal variability in the Mediterranean and Labrador Sea Water layers will be studied focusing in the dissolved oxygen variability.
