Modern multibeam sonars provide high resolution measurements of acoustic backscatter that were unthinkable just a few decades ago. However, many aspects of the data acquisition can heavily impact these measurements, reducing the data quality in the output mosaic and any attempt of seafloor characterization. This work first describes techniques to identify the presence of artifacts (e.g., bubble wash-down), then explores possible scenarios for how to reduce the lack of knowledge in such areas. Finally, it outlines an approach for how to retain the information from the processing steps used in an attempt to increase output reproducibility and reusability.
