Acoustic mapping

BY: Leo Koop



Acoustic mapping work is one of the few things that can be done at night during this cruise. Tonight is a travel night to a new research site north of the Bruine Bank. This mean that, due to my nocturnal sleeping cycle and the fact that we are not collecting new data tonight, it will be a night of organizing the data acquired in the past week. A rapid processing is performed to determine its quality as well as taking notes that will make finding specific files faster in the coming months. The acoustic data that was collected on this trip, upwards of 500 GB, includes bathymetry (depth), backscatter, and Side Scan Sonar information. Having all of this information will help to extrapolate our findings from ROV footage and grab samples to areas much larger than that of the ROV transect or grab sample location.
