Seabed mining is very much in the news today, following initiatives from the Norwegian authorities who are encouraging companies and organisations to develop technical solutions to help kick-start and service what could be both a local and a global industry. Because of this, we have also seen several traditional oil and gas seismic players announce initiatives to support this market, and other markets such as wind farm developments and offshore groundwater.

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

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.
