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)

30th China Ocean Surveying and Mapping Academic Seminar

The 30th Ocean Surveying and Mapping Academic Seminar was held in Zhuhai on 29 August. The event was hosted by the Ocean Surveying and Mapping Committee of the China Society of Surveying and co-organised by Oceanalpha Intelligent Technology. The conference attracted nearly 200 delegates, including representatives from the Ministry of Natural Resources, the Ministry of Transport, the Ministry of Water Resources, the Chinese Academy of Sciences, the Navy and manufacturers of surveying and mapping instruments. Joint operation of USV, multibeam echosounder and 3D scanner On 31 August, the participants visited Oceanalpha’s unmanned vessel base and watched a demonstration of surveying... (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)

Methane Emission Seafloor Project Benefits from Multibeam Echosounder

With the increasing concern about global warming, there is a strong focus on methane emissions from the seafloor. Indeed, today large quantities of methane – a potent greenhouse gas – are trapped within the seafloor in the form of so-called gas hydrates, solid ice-like deposits which are only stable at particular conditions of high pressure and low temperature. Since only a small volume of methane currently bubbles up into the ocean, the quantity reaching the atmosphere is not threatening, despite its greenhouse effect. However, there is a concern that, as the temperature of oceans rises, the seafloor methane hydrate deposits will...

Fugro to Collect Data for Norwegian Seabed Mapping Programme

Fugro has been awarded a hydrographic survey contract, valued at NOK 44.7 million (approximately €4.7 million), by the Norwegian Hydrographic Service. The survey is part of the MAREANO seabed mapping programme, which is financed by Norway’s Ministry of Trade, Industry and Fisheries, and the Ministry of Climate and Environment. Fugro has successfully completed numerous surveys for the programme since 2006, collecting more than 100,000 square kilometres of data. In water depths that typically range from 80 metres to 1,700 metres, the survey area of approximately 14,500 square kilometres is located between the Norwegian Sea, the Barents Sea and the Arctic...

New Expedition to Find the Wreck of Polish Submarine

A group of Polish specialists intend to explore the bottom of the North Sea in another search for the submarine 'ORP Orzeł' which was lost, and possibly mistakenly sunk by a British plane, in 1940. The two-week expedition will once again be supported by high-class equipment, including sonar and echosounders. Most of the equipment will be provided by the Marine Institute from the Polish coastal city of Gdańsk. It will be installed on a Danish keelboat. Tomasz Stachura, one of the participants of the project, called 'Santi' after the name of a sponsor company, informed the Polish Press Agency that the exploration... (read more)

Cefas Scientists Complete 6-week Autonomous Fisheries Acoustics Mission

A state-of-the-art technique for mapping and counting schools of fish has been tested on an autonomous marine platform in the North Sea, offering a new method for collecting data on fish stocks. The UK's Centre for Environment, Fisheries and Aquaculture Science (Cefas) and Liquid Robotics, A Boeing Company, USA, have successfully deployed, tested and recovered a remotely piloted Wave Glider, which was adapted to allow scientists to collect high-quality broadband fisheries acoustics data. As part of a multi-vehicle mission under the UK NERC/Defra funded AlterEco project, the Wave Glider called Lyra was deployed in the central North Sea about 270km north-east... (read more)

Bibby HydroMap Undertakes Geophysical and UXO Survey off British Coast

Bibby HydroMap was commissioned by ScottishPower Renewables to undertake a geophysical and UXO survey across a UK site to ensure items which could pose a risk to construction operations were identified. Located off the coast of Norfolk and Suffolk, the East Anglia offshore wind area has been earmarked for future development. The first area, developed by ScottishPower Renewables, was awarded a licence as part of the Round 3 category. Referred to as 'East Anglia ONE', it covers an area of approximately 200 square kilometres and is located towards the south of the development area. At present, the £2.5 billion East Anglia...

Researchers Map Seafloor Near Pine Island Glacier

The Pine Island Glacier in Western Antarctica is not only one of the fastest-flowing ice streams in the Southern Hemisphere; over the past 11 years, four major icebergs have calved from its floating tongue. In February 2017, researchers on board the German research icebreaker 'Polarstern' successfully mapped an area of seafloor previously covered by shelf ice. A comparison of these new maps with satellite images of the ice stream reveals why the glacier suddenly retreated toward the coast: at important points, it had lost contact with the ground, as the experts report in 'The Cryosphere', an online journal of the European...
