Most Complete Submarine Cartography of the INBIS Channel Published

A scientific study describes for the first time the submarine cartography of a high-latitude system in the INBIS channel, which covers tens of kilometres in the northern western area of the Barents Sea, in the Arctic Ocean. This channel is one of the few submarine valleys in polar latitudes that kept its geological architecture during the Last Glacial Maximum (LGM), according to the new study published in the journal Arktos – The Journal of Arctic Geosciences, in which the lecturer José Luis Casamor, member of the Consolidated Research Group on Marine Geosciences of the Faculty of Earth Sciences of the...

Ocean Pioneers to Explore New Business Model

The struggling economy has cost many non-profit organisations vital financial support as their benefactors rein in spending. Initially funded entirely by philanthropic donations averaging USD 1 million per year, AURORA has been forced to reinvent its business model now that its backers can no longer provide support. This has led AURORA to pursue some alternative income streams that include seeking commercial survey work, chartering its vessels to other organisations and individuals, and even offering tourists a place onboard during archaeological expeditions.     It's a sign of the times that a non-profit research group would have to seek commercial income...

Student Autonomous Underwater Challenge - Europe

The Student Autonomous Underwater Challenge – Europe (SAUC-E) is an annual event providing an opportunity for student-led teams to design and build a small autonomous underwater vehicle (AUV) to compete over a variety of challenges. The University of Southampton team (Figure 1) – the winners of SAUC-E 2007 – are aiming to retain their title at the 2008 edition to be held from 7 to 11 July at IFREMER in Brest (France). A new vehicle is in the latter stages of development for this year’s challenge to try to emulate the achievements of its predecessor.<P> The Student AutonomousUnderwater Challenge –... (read more)

‘Subsea Internet of Things’ to Transform Amount of Information Available

Hydro International Interviews Brendan Hyland WFS Technologies
It’s fascinating to see that communication techniques are evolving. On the shore there is already a clear trend towards eliminating cables and wires. So a logical consequence would be to see this also happening underwater. One of the pioneers of underwater wireless communication has been Wireless Fibre Systems Technologies, or WFS Technologies. They have succeeded in making underwater communication wireless and are even going a step further by initiating what they themselves call the 'subsea internet of things'. Hydro International interviews Brendan Hyland, founder of WFS Technologies. What made you start WFS Technologies? I started WFS to deliver innovative wireless... (read more)

Sea Change – Dive into Opportunity

OCEANS ’15 MTS/IEEE Washington, DC Conference
A little over 2,000 people converged on the Gaylord National Resort and Convention Center October 19-22 for OCEANS ’15 MTS/IEEE Washington, DC. They comprised a wide variety of technical professionals, researchers, industry leaders, educators, policy makers and students –  all interested in sharing the latest information on how marine technology and ocean engineering can support exploring, monitoring, protecting, and wisely using the world’s ocean resources. The conference was honored to have Congressman Sam Farr, co-chair of the House Oceans Conference and Dr. Rick Spinrad, Chief Scientist of the National Oceanic and Atmospheric Administration (NOAA), as the Honorary Co-chairs. We were... (read more)

Depth of Burial – Galloper Offshore Wind Farm

Galloper Offshore Wind Farm is a 353MW wind farm project located 30km off the coast of Suffolk, UK. It is now in full operation and each year will generate enough green electricity to power the equivalent of more than 380,000 British homes. The construction of the wind farm created almost 700 UK jobs and its operation has created around 90 direct and indirect long-term jobs in the local area. A 60-strong team will operate and maintain the wind farm day-to-day from a base under construction in Harwich International Port. There are 56 wind turbine generators (WTGs) located in water depths... (read more)

Towards a New Sonar Imaging Concept for Survey

Side-scan Sonar or Synthetic Aperture Sonar
Since the 1970s and the emergence of the first analogue systems, the sidescan sonar (SSS) has experienced several major revolutions. Signal digitization in the 1990s has significantly improved signal quality and robustness. Dual-frequency and interferometric systems have allowed better analysis of the seabed. In the mid-2000s, a significant development was the appearance of multibeam SSS with dynamic focusing. These systems, as well as the integration of the first gap fillers, have allowed considerable productivity gains and improved imaging quality. (by Frédéric Mosca and Didier Charlot, iXblue, France) SSS Limitations But SSS has not evolved much over the past decade. Although... (read more)

C & C Technologies, Inc.

Growing to become a 'big guy'
What started out as a small niche company specialising in hydrographic multi-beam surveys has really taken flight since 1992. C&C Technologies has been led in many other directions than multi-beam survey alone, growing to become a ‘big guy’ with a market share in AUV survey exceeding 90% and estimated total revenues of US$75 million in 2006. Thomas and Jimmy Chance were raised in the survey business, helping their father John E. Chance build the largest privately owned survey company in the world. In 1992, when their father sold his company to Fugro, the Chance brothers resigned their management positions and... (read more)

Deep-water Coral Reefs

Acoustic recognition and geological setting
Cold water coral reefs, notably the stone coral Lophelia pertusa, have been found extensively in deep Arctic waters such as the Norwegian Sea. The use of multibeam echosounding, together with advanced visualisation and analysis tools, has been a key to many spectacular discoveries. The world's largest cold water coral reef - the Røst Reef - was mapped in detail in October 2002. Located in the dramatic setting of a large submarine slide, this provides an excellent example of how catastrophic geological processes can create special marine habitats. Another major reef complex - the Sula Reef - demonstrates how mounds select... (read more)

Leading positioning solutions
On 12 August 2002 IXSEA and OCEANO Technologies successfully completed their merger previously announced in March 2002, revolutionising the landscape of the positioning industry. With 100 staff and over 25 years joint knowledge in gyroscopes and underwater acoustic technologies, the new company IXSEA OCEANO aims at providing leading positioning solutions. The growing activity of the Marine Community in exploration, survey and oceanographic research in ever deeper waters has increased the need for very accurate and reliable positioning, with real-time continuous data. The first answer to this need was acoustic positioning (LBL, USBL). Recent needs for AUV positioning saw the emergence... (read more)
