Ifremer multibeam database : cruises from 1991 to 2018.

Data sets acquired onboard Ifremer research vessels are processed according to a common flow :

- Time and acquisition lines selection

- Removing outliers by automatic filtering

- Manual cleaning and residual artefact removing

- Producing a digital terrain model (DTM). Depth layer is calculated as the average of soundings in each pixel. The grid resolution is 1/16 of arcminute. All DTMs are merged into a unique file.
