研究目的
To quantify hydrocarbon seeps by subsea imaging utilizing camera systems and frontal illumination setups on board remotely operated vehicles, showcasing improved methodological guidelines for the seep quantification operation together with a novel automated post-mission evaluation.
研究成果
The automated method for quantifying and characterizing rising gas bubbles provides a significant performance boost, allowing for the analysis of up to 55,000 images on a working day compared to manual methods. This enables the study of seeps over longer periods for searching influences such as tidal gradients or other pressure variations. The method is comparable with results from literature and manual quantification methods, offering consistent results and opening new possibilities in the assessment of bubble stream characteristics.
研究不足
Current technical limitations include the inability to optimally record the movements of rising objects due to the required exposure time, resulting in a blur. Additionally, the geographical extension of seep structures poses restrictions, as single sensor systems are not likely to address the full range of gas and oil seeps in the marine environment.
