Hydrographic Education During a Lockdown

Experiences in the Netherlands
On 12 March, the Dutch government decided to ‘lockdown’ all activities involving multiple persons, including education. That decision immediately affected the hydrographic institutions in the Netherlands. The Netherlands has an active four-year Cat A course in Ocean Technology at the NHL Stenden University of Applied Sciences – Maritime Institute Willem Barentsz (MIWB), and a 3+3 month Cat B course at Skilltrade. Both had to cope with the lockdown in different ways due to their different set-ups and student populations. Organizational Situation After Lockdown Although education is not a ‘contact’ profession in the strict sense (or at least it shouldn’t be),... (read more)

Fugro Maps Arctic Ocean for Norway’s MAREANO Seabed Mapping Programme

The Norwegian Hydrographic Service has awarded Fugro another hydrographic survey contract as part of the MAREANO seabed mapping programme, financed by Norway’s Ministry of Trade, Industry and Fisheries, and the Ministry of Environment. Fugro has completed ten surveys for the programme since 2006 and acquired over 140,000 km2 of data. This latest survey will collect high-resolution, high-density multibeam echosounder and sub-bottom data to produce seamless datasets for the Norwegian mapping programme. The fieldwork will run from June to late October this year. The survey area covers approximately 2,700km2 over Spitsbergenbanken, a large bank in the Barents Sea, in water depths ranging...

Kongsberg Maritime Releases New Features on its EM 2040 MKII Multibeam Echosounder

Kongsberg Maritime has released two new features on its EM 2040 MKII multibeam echosounder. The first enables the use of dual high frequencies to survey wide swaths of the seabed at much higher resolutions than before, while the second facilitates the simultaneous collection of backscatter data using multiple frequencies. These cutting-edge functionalities constitute a significant upgrade to the current system, which already offers outstanding range and resolution. Broadband Multibeam Echosounder System The EM 2040 MKII is a broadband multibeam echosounder system, which uses frequencies from 200kHz to 400kHz to yield a wide swath of up to 170 degrees. With the... (read more)

How to Simplify Survey Reporting

Wouldn’t it be great to work on a hydrographic project without spending a lot of time looking for all the elements needed for a professional report? This was what Sanyal Sunil had in mind when he developed SURge, a digital tool to simplify survey reporting. Wouldn’t it be great to work on a hydrographic project without spending a lot of time looking for all the elements needed for a professional report? This was what Sanyal Sunil had in mind when he developed SURge, a digital tool to simplify survey reporting. Hydrographic survey reporting has always been a headache for surveyors in the field, as they have to spend a lot of time formatting the reports, finding the correct logos and diagrams, displaying observations schematically, and carrying out irrelevant calculations, all of which have to be neatly represented in the report but have nothing to do...

Will New Long-endurance Navigation Capabilities in Loch Ness Discover Its Secrets?

New standards in long-endurance underwater navigation and automated subsea positioning have been set following the successful completion of a joint project led by subsea technology specialist Sonardyne International Ltd., with partners the National Oceanography Centre (NOC) and L3Harris. The two-year, £1.4 million Precise Positioning for Persistent Autonomous Underwater Vehicles (P3AUV) project, part-funded by Innovate UK, set out to integrate existing and emerging technologies to deliver a step-change in unmanned platform endurance and navigational precision. In addition, the project also set out to increase the use of autonomy in offshore survey positioning operations using unmanned surface vessels (USVs), and in the... (read more)

USV Completes First Autonomous Circumnavigation of Antarctica

High-quality and Reliable Data Is Needed for Research Use
A 7m (23ft) long, wind-powered unmanned surface vehicle (USV) has become the first unmanned system to circumnavigate Antarctica. Known as SD 1020 and equipped with a suite of science-grade sensors, the vehicle collected data in previously uncharted waters, enabling new key insights into ocean and climate processes. A 7m (23ft) long, wind-powered unmanned surface vehicle (USV) has become the first unmanned system to circumnavigate Antarctica. Known as SD 1020 and equipped with a suite of science-grade sensors, the vehicle collected data in previously uncharted waters, enabling new key insights into ocean and climate processes. USV SD 1020 left for the 196-day mission from Southport in Bluff, New Zealand, on 19 January 2019. It returned to the same port on 3 August after sailing over 22,000km (13,670 miles or 11,879 nautical miles) around Antarctica. During the mission, the vehicle survived freezing temperatures, 15m (50ft) waves, 130km/h (80mph) winds... (read more)

Preparing for Hydrographic Artificial Intelligence Network and Systems

Success Depends on the Quantity and Quality of All Available Data
With the ever-increasing and affordable availability of capacity and computing power to process and store data, the emergence of artificial intelligence (AI) in marine geomatics, ocean sciences and hydrography is palpable. Mathematical models are very powerful, but their reliability must be validated and demonstrated using calibration points. It's the same thing for AI. It cannot emulate and learn properly if it cannot rely on observations that represent reality. In the commercial shipping world, AI-based technologies are about to be tested, resulting in additional bathymetry and hydrography needs that will quickly become necessary and critical. Commercial Marine Autonomous Surface Ships (MASS)... (read more)
