Bathymetric model of the wreck of ferry Estonia3D ModelNoAI
The Estonian Safety Investigation Bureau (Ohutusjuurdluse Keskus), the Swedish Accident Investigation Authority and the Finnish Safety Investigation Authority are performing a preliminary assessment of the new information that became evident in September 2020 about holes in the hull of the passenger ferry Estonia.
This model is based on two bathymetric surveys using multi-beam echo sounder (MBES) carried out on 13 July 2021 by Stockholm University during preliminary marine surveys. The first survey covered an area of approximately 2.6 km × 1.8 km; the second focused around the wreck (area approximately 680 m × 340 m). The processed digital elevation models of the two surveys have been assembled into a high-resolution grid (cell size: 0.50 m × 0.50 m). For more information of the MBES, its survey and the corresponding data processing, see pages 16, 23-24 and 30-41 of the University of Stockholm’s EL21-Estonia report.
