Aviso altimetry(*) referred to MDT_CNES-CLS09(**) was used
to calculate Absolute Dynamic Depth.
(*) The altimeter products were produced by Ssalto/Duacs
and distributed by Aviso, with support from Cnes
(http://www.aviso.oceanobs.com/duacs/).
(**) MDT_CNES-CLS09 was produced by CLS Space Oceanography Division
