%X To improve the quality of the bathy-messages, sent to the Global Transmission System of the World Weather Watch via the Argos satellite, by ORSTOM C.L.S. service Argos software onboards ships of opportunity, the following operations are implemented : i) a combination of a nonlinear median filter in order to despike the eXpandable BathyThermogramme profile prior to onboard quality control, ii) plus a linear Hanning filter, to filter out the small scale features before using the Broken stick data reduction method (that gives directly the required number of significant data point without iteration), iii) and a final regression fit. Only bathy-messages are computed only to the deph of the deepest "good" data point. So very few bathymessages are rejected later on, during the successive quality controls. (Résumé d'auteur)
