Free-rising bubble plumes are an amazing phenomenon that has an impact on our daily activities, such as water purification or boiling water. They are involved in environmental pollution, such as underwater gas discharges or gas pipeline leaks, like the Nord Stream leakage. They are also used in industrial applications such as metal agitation or heat transfer enhancement. Studying the dispersion of bubble plumes in pressurized water can highlight the effects of ocean depth on the extent of the influence of bubble plumes on the sea surface. This will make it possible to quantify the impact of this type of risk and facilitate the design of subsea gas pipelines to reduce bubble dispersion.
