AUV Tracking System Tested in Loch Ness

A collaborative research project called Autonomous Surface and Sub-surface Survey System (ASSSS) aims to deliver an integrated system to provide a means of conducting low cost, shore based, full water column marine surveys using multiple unmanned systems. The project, part funded by Innovate UK, hopes to encourage wider adoption of unmanned systems.The project is being led by a U.K. based developer of unmanned and autonomous marine systems, ASV Global. It combines the advantages of autonomous underwater vehicles (AUVs) and autonomous surface vehicles (ASVs) to further data gathering opportunities.

MG3 & Satellite Derived Bathymetry

Operation of marine survey vessels in shallow-water coastal environments is a dangerous endeavor. A subsurface obstruction can tear a multi-beam sonar from its tow cable, resulting in loss of the expensive device and potential delay in the expedition. Lost equipment, however, is a minor inconvenience compared to the equally real possibility of the ship running aground in poorly charted waters, endangering the safety of its crew and incurring millions of dollars in damage.For this reason, survey vessel operators invest considerable time and money to minimize the risk involved in each voyage. They are

Old Sea Ice is Disappearing from the Arctic Ocean

Sea ice grows throughout the fall and winter, and melts throughout the spring and summer. But not all Arctic sea ice melts; some portion of the ice survives at least one melt season, persisting throughout the summer months. This ice is usually thicker and more resistant to melt than ice that's less than a year old, and therefore more likely than first-year ice to survive the coming melt season. As Arctic sea ice often reaches its maximum extent around late February or early March (around the ninth week of the calendar year) that's a good time to measure multiyear versus first-year ice.In the

we not just support, but also actively engage in Seabed 2030. As a global company operating in and on the oceans, our participation is socially responsible, contributes to ocean stewardship and, quite simply, is the right thing to do.It is our belief that Seabed 2030 will not eliminate the need for our marine site characterization services, but rather increase its demand. Only through a comprehensive mapping of the ocean will areas of interest become known, and we fully expect that within those areas of interest, Fugro’s high resolution mapping services will still be required to support our customers&rsq

Scientists Study Largest Underwater Volcanic Eruption

In July 2012, airline passengers flying over the Southwest Pacific Ocean spotted a large and unusual object floating on the water’s surface.    That object, which turned out to be a giant raft of pumice, was evidence that an underwater volcanic eruption had occurred. And as the raft continued to grow to roughly the size of Philadelphia, scientists observed that the eruption was extraordinarily large.   The eruption had occurred at the Havre volcano northeast of New Zealand, and was the largest to take place underwater in the past century.   “We knew it was a

Ocean Floor Geophysics Inc. (OFG), in cooperation with Fukada Salvage and Marine Works Co. Ltd. (Fukada), has completed a third high resolution Controlled Source Electromagnetic (CSEM) survey of near surface gas hydrates using the Scripps Institution of Oceanography (Scripps) Vulcan system for the National Institute of Advanced Industrial Science and Technology (AIST) in Japanese waters.Following the CSEM surveys and 3D inversion models completed in 2014 and 2015, the 2017 survey comprised more than 413 line kilometers of high resolution data collected in depths up to 1,640 m from the Fukada vessel

Geochemical Campaigns.“We have been operating in Brazil for more than two decades, providing a wide variety of geotechnical, survey, subsea and geoscience services, principally for the deepwater oil and gas industry,” he added. For almost two decades Fugro has been at the forefront of modern marine seep-hunting operations in the energy sector and has led the market in integrated multibeam and geochemical coring campaigns.Project deliverables will be used by energy companies to help optimise and refine their exploration and development activities in this prolific region

buoys to direct water traffic and to protect vulnerable benthic ecosystems such as seagrass communities and coral reefs in U.S. waters. However, most buoys are currently attached to the seafloor by concrete anchors, also called sinkers, and heavy metal chains that can have a significant impact on marine life. Sinkers can damage life on the seafloor under their heavy footprint, and when the connecting chains are lax, they can scrape off seagrasses, seaweeds and corals around the sinkers as waves and wind push the buoys around.The Coast Guard has been struggling to find a solution for more than 20

SCM will still work as the compensation coefficients are calculated at the beginning of each mission.”OFG said its SCM systems are being used for AUVs around world on various applications ranging from geological mapping, mine-countermeasures, and vessel signatures, to unexploded ordnance (UXO) and marine archaeology.Equipping the Gavia with the OFG SCM system for AUVs enables the collection of real-time compensated data that removes the magnetic signature of the AUV ensuring that the ambient field is being measured rather than the AUV itself. Combining the compensated three-vector magnetic data of

Fugro to Train Saudi Students in Marine Technology

Fugro’s new partnership with KAUST (King Abdullah University of Science and Technology) was marked recently with the inauguration of the KAUST - Fugro Center of Excellence for Marine Technology. The new center will provide training in ROV operations and hydrographic survey within the Kingdom as part of the Saudization program.KAUST’s facilities and location, on the shore of the Red Sea, are ideal for addressing the challenges associated with mapping the Red Sea, large tracts of which remain unexplored due to extreme depths, temperature and salinity.“This close working relationship

Using a Mocness Trawl the expedition also collected plankton at a record depth of 5,000 meters. The Atacamex 2018 expedition represent a milestone for marine science in Chile, as researchers there pursue seminal work in deep-sea exploration and research.The hadal zone is the deepest region of the ocean, from 6,000 to 11,000 meters below sea level. Their access and study is extremely difficult due to the high pressures and great difficulties of reaching

It received new cleaner and more efficient diesel engines, the latest navigation and ship-positioning systems, as well as sophisticated sonar, allowing it to map the ocean floor in sharper detail and even differentiate between species of fish and other marine life.The Thompson's laboratories were updated to include advanced IT infrastructure to better support scientific data collection and analysis at sea, while also enabling improved real-time communications with shore. Several critical sensor systems also were replaced, providing upgraded scientific
