A quick processing with SEISPRO was made on board to improve the signal/noise ratio by applying a linear gain ranging from 1 to 5. Example of the recorded and processed data is shown in Fig.20.
The data ranged from good to acceptable. Chirp profiles show the first tens of meters of sedimentation (where sediments are present, especially outside the deeps), major evaporite mobilization, fault scarps, and oceanic-type seafloor, highlighted mainly in the deeps by many diffraction hyperbolae.
