481 GNGTS 2021 S essione 3.2 Conclusions Processing Chirp data is limited by the lack of multiple channels and by the common practice of recording the signal envelope, instead of the original waveforms. Nevertheless, some processing can still improve the images for the shallow sediments and even interesting features in the water layer. The occurrence of plumes due to fluid release from shallow sediments is well imaged by the analyzed data. The presented data show that a target processing of the chirp data can improve the imaging and consequently the identification of the fluid accumulation and seeps.
