Sonar Plays Integral Role in First Human Reaching Deepest Point in Atlantic

Kongsberg Maritime has announced that the EM 124 sonar, installed aboard the DSSV Pressure Drop, played a key role in the deepest solo human submersible dive completed by the Five Deeps Expedition. Expedition founder and submersible pilot, Victor Vescovo, reached the bottom (depth of 8,376 metres) of the Puerto Rico Trench in his private submersible, the Limiting Factor, following precision mapping of the ocean floor completed by the EM 124. The Kongsberg EM 124, released in 2018, is the fifth generation multibeam system from Kongsberg Maritime and the successor of the EM 122. It is a modular multibeam echosounder that... (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)

ASL Announces Next Generation in Acoustic Backscatter Measurements

A new tool to measure both sediment concentration and sediment size are being built by ASL Environmental Sciences (ASL). The Multi-frequency Ultrasonic Device (MUD) is based on ASL's successful Acoustic Zooplankton Fish Profiler (AZFP). The MUD and AZFP echosounders can be configured with up to four frequencies ranging from 38 kHz to 2 MHz. The MUD prototype is based on a set of higher frequencies (200 kHz, 769 kHz, 1.2 MHz and 2.0 MHz) that will allow for a broad range of particle size discrimination. While the AZFP is a high gain device for low scattering conditions and the greatest... (read more)

Fugro Receives Award for Efforts to Close Seabed Mapping Data Gap

Fugro has received the Marine Technology Society (MTS) 2018 Compass Industrial Award for outstanding private sector contributions to marine science and technology. In selecting Fugro for the honour, MTS cited the company’s legacy of marine survey innovation and its industry-leading support of The Nippon Foundation-GEBCO Seabed 2030 Project (Seabed 2030). David Millar, Fugro’s government accounts director for the Americas region, accepted the award. “We are grateful to MTS for recognising our efforts with Seabed 2030. Given that a significant proportion of Fugro’s work is ocean related, supporting this project is a way for us to positively impact global society and... (read more)

Hydrographic Surveying: Where Do We Stand

The Ever-increasing Accuracy of Mapping the Surface Waters
Hydrographic surveying is highly specific and requires a suite of advanced acquisition and positioning sensors attached to a mobile survey platform as well as sophisticated software to allow the correct combination of all the data. For those within the industry, the advances over the last decade may feel more like an evolution rather than a revolution. If we look back one, two or even three decades, we can see the enormous leap hydrographic surveying has taken. Where do we stand, and what can we expect for the near future? In this article, we will look at the present compared to... (read more)

Two MVP30-350 Systems for Geological Survey of Ireland

The Geological Survey of Ireland (GSI) has purchased AML Oceanographic’s Moving Vessel Profiler (MVP) to simultaneously improve the productivity, safety, and data quality of their survey operations. Working in partnership with the Marine Institute of Ireland under the joint programme INFOMAR, they have committed to having all Irish waters mapped by 2026. The addition of MVP30-350 systems to their two 16m survey catamarans is expected to facilitate on-time completion of the project. “The MVP is expected to improve productivity by over 10%, but more importantly they will enhance safety,” explained Project Manager Sean Cullen. "Instead of having crew members venture... (read more)

Research Icebreaker Polarstern Begins Antarctic Survey Season

On 10 November 2018, the research icebreaker Polarstern left its homeport of Bremerhaven, bound for Cape Town, South Africa. This marks the beginning of her Antarctic season, in which oceanographic fieldwork in the Weddell Sea, a resupply mission to the Neumayer Station III, and explorations of the Larsen C ice shelf region and the South Shetland Islands are on the agenda. The ship is expected to return to Bremerhaven in June 2019. An expedition to the Larsen C ice shelf abutting the Antarctic Peninsula will be at the heart of the upcoming Antarctic season. The Peninsula is one of the fastest-warming... (read more)

FarSounder Joins NOAA as a Trusted Node

FarSounder is the most recent company to join the International Hydrographic Organization’s Crowd-Sourced Bathymetry (CSB) initiative by becoming a “trusted node” with the NOAA. This project enables mariners to voluntarily contribute seafloor depths measured from their vessels to NOAA’s data repository. The partnership can be seen as a logical step because FarSounder’s customers regularly travel to remote areas with poorly maintained nautical charts, using a FarSounder 3D-FLS for real-time navigation. Due to the development of FarSounder’s Local History Mapping (LHM), the latest feature of its SonaSoft software, users now have the ability to create a real-time chart of the seafloor... (read more)

Fugro Acquires Data in Offshore Eastern Canada Seep Hunting Programme

Fugro has successfully completed the geophysical acquisition portion of a 2018 Carson Basin seep hunting programme in offshore eastern Canada. The work scope covers an area of 18,875 square kilometres in water depths from 300 to 3,300 metres in this frontier region offshore Newfoundland. From its deep-water survey vessel, 'Fugro Searcher', Fugro acquired multibeam echosounder data (bathymetry, backscatter intensity and water column) and sub-bottom profiler data. The data was used to interpret geologic features and optimise target selection for geochemical sampling and heat flow measurements. The second portion of the programme – coring for geochemical sampling, shipboard geochemical screening analyses... (read more)
