Seabed mineral exploration

How can oil field geosciences be used in the exploration of seabed mineral deposits?
July 21, 2021
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.
 
The impetus for increased interest in this area is the accelerated demand for metals used for all things electric, in turn driven by the movement to reduce our dependence

July 2023: Global air and ocean temperatures reach new record highs

 

 

 

DATE:8th August 2023

Bonn, 08/08/2023 

 

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.

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

North Sea wrecks: Toxic legacies of war

 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.
