The submerged geometry of 17 icebergs was surveyed with a multibeam echo sounder. Work was carried out from a survey launch deployed from the research expedition vessel Akademik Tryoshnikov.
The automated hydrographic system used a Reson SeaBat 7125. Its transducer was rotated by 30 degrees to collect data up to the water surface.
After data processing, 3D iceberg models were produced and the volume of each submerged section was calculated.
