Applying Side-scan Sonar and an AI-powered Platform for Environmental Protection

Over the past few years, the University of Delaware, USA, has participated in a state programme which supports rescuing abandoned crab pots from the seabed and researches technologies to make the search process more effective. It has developed advanced sonar surveys from a boat with further map storage and processing in SPH Engineering’s ATLAS AI-powered platform. The evaluations proved to be time-effective and more accurate in comparison to the detections of human annotators.  Blue crab fishing is a popular commercial and recreational activity throughout the United States. In order to catch these crabs, people use 'crab pots'. These devices are placed... (read more)

Teledyne CARIS AI Software Contributes to Successful UTAS USV Mission

Teledyne CARIS, a Teledyne Technologies company, was an integral part of the illustrious team involved in the ground-breaking uncrewed offshore survey mission in the Atlantic Ocean. Teledyne CARIS’ Mira AI and CARIS Onboard software were present on the vessel to enable autonomous survey and real-time processing operations. The mission’s Uncrewed Surface Vehicle (USV) built by SEA-KIT mapped over 1,000 sq. kms of the ocean floor in 22 days, while being continuously monitored via satellite communications at its Remote Operations Centre in Essex, United Kingdom. A specialized team comprised of the GEBCO-Nippon Foundation Alumni Team operated the survey equipment and provided... (read more)

600 Researchers to Spend a Whole Year Trapped in the Ice

The Biggest Arctic Expedition of All Time?
On 20 September 2019, the German research icebreaker Polarstern left Tromsø, Norway, for what could be the biggest Arctic research expedition of all time. Once she reaches the destination, the ship and her crew will become trapped in the ice and spend an entire year drifting through the Arctic Ocean. Over 600 scientists and surveyors from 19 countries are on board Polarstern for the MOSAiC expedition, and several times that number of researchers will subsequently use the data gathered in further climate and ecosystem research. The mission is being spearheaded by the German Alfred Wegener Institute, Helmholtz Centre for Polar and... (read more)

Mapping Submarine Groundwater Discharge with Thermal Infrared Imaging

Using Cutting-edge Technology and High-resolution UAS
Submarine groundwater discharge (SGD) is a significant part of the water cycle that delivers anthropogenically derived and naturally occurring nutrients to coastal waters. As part of the drive to develop methods to prevent the degradation of coastal water quality, research conducted at the University of North Carolina Wilmington attempts to address the ambiguity associated with SGD point source locations. This case study outlines how cutting-edge high-resolution unmanned aerial system (UAS) thermal infrared (TIR) imaging methods have been coupled with the newest technology for continuous and autonomous SGD monitoring. Submarine groundwater discharge – the process in which groundwater flows down-gradient through... (read more)

Fugro’s Subsea Engineering Solutions Key to Ireland’s Corrib Gas Field Integrity

Fugro has used the survey vessel Edda Sun to deliver an inspection, repair and maintenance (IRM) project for Corrib, Ireland’s biggest natural gas field, on behalf of Vermilion Exploration and Production Ireland Limited (Vermilion). The project included deepwater pipeline surveys, inspection of subsea structures, and maintenance tasks using Fugro’s FCV3000 remotely operated vehicle (ROV), and the Edda Sun is now returning to the North Sea to continue its 2020 IRM programme. Before mobilizing offshore, Fugro combined subsea virtual simulation, engineering design and physical testing to develop a predictive understanding of the offshore inspection and maintenance tasks. This provided in-depth knowledge of... (read more)

Scientific Challenges in a Crucial Region for Planet Earth

Remote, Frozen, Critical and Changing: the Weddell Sea
Located in the Atlantic sector of the Southern Ocean, the Weddell Sea generates extremely dense bottom water that spreads into all the world’s ocean basins, transporting oxygen, CO2 and other solutes. Everything that is added here is transferred into the abyssal oceans, including anthropogenic CO2. However, changes are taking place in the Weddell region that will have an impact on other oceans and on the global climate. The Weddell Sea (Figure 1) is a huge embayment between the Antarctic Peninsula and the Antarctic continent, situated at the southern edge of the Atlantic Ocean. The boundary of the Weddell Sea to...
