We propose in this work to characterize the sub-surface bubbles occurrence conditions from acoustic data analysis acquired during surveys in relatively shallow water with the IFREMER research vessels Thalassa and Pourquoi Pas?. The methodology of data analysis used in this work allows us to characterize the sailing conditions influence on bubble sweep-down occurrence. The correlation between sailing conditions and acoustic perturbations tends to demonstrate that the presence of bubbles under the hull is clearly related to the wind speed and natural aeration, and that surface bubbles are advected differently in the water column by the two vessels PY 2016 PD JAN SO Ocean Engineering SN 0029-8018 PU Pergamon-elsevier Science Ltd VL 111 UT 000368219600005 BP 34 EP 42 DI 10.1016/j.oceaneng.2015.10.040 ID 40557 ER EF
