Introduction Seabed Surveying using ROVs/AUVs

We will cover the installation of vessel and ROV survey equipment and explain the importance of offsets, calibrations and installation checks. We will discuss the relevance of the installation positions on both vessel and ROV in providing the best quality data without interference and explain the different types of surveys and the equipment needed to ensure accurate time stamping. Should you be interested, send us a message and we will forward more information. (read more)

Seabed 2030 and Five Deeps Sign Agreement

Seabed 2030 and the Five Deeps Expedition have signed an agreement which lays the groundwork for previously unexplored areas of the seafloor to be mapped and the resulting data made available for public use. Seabed 2030 is the collaborative project of The Nippon Foundation and GEBCO aspiring the complete seabed mapping by 2030. In this cooperation with the Five Deeps Expedition, the world's first manned expedition to the deepest point in each of the five oceans, the Seabed project is ensured of data contributions in areas which would not have been collected otherwise. In addition to data gathered at trench sites,... (read more)

Swire Seabed Orders HUGIN Autonomous Underwater Vehicle

Kongsberg Maritime has announced that Swire Seabed of Bergen, Norway has ordered a HUGIN AUV System configured for commercial survey applications. The Swire Seabed HUGIN AUV System is rated to 4,500 metres and equipped with Kongsberg Maritime’s HISAS 1032 Synthetic Aperture Sonar and EM2040 multibeam echosounder. Other payload sensors integrated in the Swire Seabed HUGIN AUV include the CathX Ocean 48.5-degree field of view still image camera and laser profiler, a sub-bottom profiler, magnetometer and turbidity sensor. To make the best use of the extensive payload sensor suite, the Swire Seabed HUGIN also includes Kongsberg Maritime’s automatic pipeline tracking solution,... (read more)

SonarWiz 7 Introduces Seabed Characterisation Tool

One feature of SonarWiz 7 is the Seabed Characterisation tool. It incorporates bathymetric slope, roughness, TPI and any spatially distributed variable that can aid the characterisation algorithm to generate classes of texture.  From that, it produces a vector polygon layer that can be exported for use outside SonarWiz. Unlike producing the analysis in a GIS or image processing package, SonarWiz performs the analysis BEFORE the data is mosaiced and geo-referenced. This greatly reduces the impact of artifacts in the nadir and far field, which can be difficult to remove and cause unnecessary rework.   (read more)

Seabed Geosolutions Mobilises Ocean Bottom Node Survey

Seabed Geosolutions has been awarded a 4D baseline ocean bottom node project in West Africa, with a duration of six weeks. The crew is currently in the mobilisation phase of the project. The bottom node survey project will support the optimisation of the recovery rate during the development and production phases of oil and gas fields, by providing high quality data on hydrocarbon prospects, reservoir characteristics and potential geohazards. The project positions the company well to respond to other potential projects in the region.   (read more)

Research Expedition to Map Scottish Seabed

Slow Recovery of Coral Reef Shows Impact of Bottom Trawling
Newly developed 3D imaging technology has allowed scientists to map Darwin Mounds, a unique area of cold-water coral reefs off the coast of Scotland, to see whether it has recovered since being declared a Marine Protected Area sixteen years ago. The images show that in areas of the Darwin Mounds that had been heavily trawled, coral growth is still very sparse, and there has been no real recolonization. However, healthy coral growth was found in parts that had only been minimally damaged by bottom trawling, indicating that marine conservation measures are most effective when they are put in place before damage occurs....

Tracking System for Live Seabed Power Cables

The new Powertrack subsea power cable tracker is being launched by Teledyne TSS at Ocean Business to close a gap in the offshore survey industry’s inventory of marine detection technology. The company’s research department has overcome the problem of tracking live power cables by developing a system that is capable of detecting the harmonics of AC tones in all AC and DC utility cables whether they are three or single phase and the same system can detect them regardless of whether they are carrying power or not. Unlike pipelines, cables have a much smaller metallic profile which makes them considerably... (read more)

10 Years Seabed Celebrated with Multibeam Quiz

Hydrographic professionals are challenged at the occasion of the 10th anniversary of Seabed, based in Amsterdam, The Netherlands. Seabed opened its doors at 9 March 2004 and has chosen to celebrate this milestone, asking three questions to be answered – the winner can look forward to a bottle of brandy. During Oceanology International, glasses will be raised on 11 March 2014 in Stand H650. To qualify into the quiz, participants need to answer three questions: What is the prize of the complete set on the image? What is the weight of the set? What is the prize per kilo? The...

In situ Measurements of Seabed Mobility

Partrac has recently directly measured seabed erosion and deposition rates at a deep water location on the UK continental shelf. This initiative comprises part of a partnership project led by Portsmouth, NOC and Cefas and funded by the UK Natural Environment Research Council (NERC) and supported equally by Defra as part of the Marine Ecosystem Connections (MECs) project.   In a collaborative venture with Dr Gary Fones of Portsmouth University and Dr Ruth Parker and her colleagues at the Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Partrac deployed their 'Voyager II' benthic flume at three offshore sites as part of...

ISE Explorer AUVs to Map Arctic Seabed

International Submarine Engineering handed over two Explorer Autonomous Underwater Vehicles (AUVs) to Natural Resources Canada (NRCan) on 22nd September 2009 at a ceremony held onboard ISE's research vessel in Indian Arm, BC. The event was attended by Mr. John Weston, Member of Parliament for West Vancouver and the Sunshine Coast on behalf of the Honourable Lisa Raitt, Minister of Natural Resources.   The vehicles will be deployed to the high Arctic next year to map the seabed in support of Canada's land claim under Article 76 of the United Nations Convention on the Law of the Sea (UNCLOS). Canada has... (read more)
