Waiting for monday's BEA press release, to get an idea of the areas examined by the Emeraude submarine during the 1st stage of the search, you may refer to the 2nd interim report delivered on the 17th of dec. 2009:
http://www.bea.aero/docspa/2009/f-cp...90601e2.en.pdf .Page 82 you will find the weighted results of the search area (according to the capacity of the means deployed): the red & orange areas, west south-west of the 1st search area (explored using the TPLs, rendered in green), are presumably those probed by the Emeraude (the little isolated green area in the western part is related to the Meteo France backdrifted crash area).
