Improving results with refraction corrections
Accurate bathymetric mapping of shallow areas is essential for many offshore activities. Through Structure from Motion (SfM) and Multiview Stereo (MVS) techniques, images can provide a low-cost alternative compared to Lidar and sonar systems while offering important visual information. This article presents a new framework for mapping the seabed in clear and calm shallow waters for small- and large-scale surveys using aerial imagery and machine learning to correct the geometric effects of refraction on the 3D point clouds and the imagery.
SfM is a photogrammetric technique for estimating 3D structures from 2D image sequences. It involves acquiring images from several positions relative to the object of interest. To establish

Investigating abandoned munitions on the seabed
Some 290 shipwrecks lie in the Belgian part of the North Sea alone, with probably more than 1,000 in the entire North Sea, many of them silent witnesses to the two world wars. Until recently, the environmental impact of these wrecks was largely unknown and, as far as the presence of munitions is concerned, they represented a true Pandora’s box. The North Sea Wrecks project has changed this. Researchers examined the munitions and the possible release of toxic substances from a few selected wrecks in the North Sea. Are these wrecks really leaving us with a toxic legacy of war, or are we worrying about nothing? In this article, we try to discover the answer.

Daily global sea surface temperature (°C) averaged over the 60°S–60°N domain plotted as a time series for each year from 1 January 1979 to 31 July 2023. The years 2023 and 2016 are shown with thick lines shaded in bright red and dark red, respectively. Other years are shown with thin lines and shaded according to the decade, from blue (1970s) to brick red (2020s). Data: ERA5. Credit: C3S/ECMWF.
