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.
