Glider Launched in the North Atlantic As Part of EU Project

The Irish Marine Institute's marine glider was deployed in to the North Atlantic Ocean as part of the 5th project meeting for the Innovation in the Framework of the Atlantic Deep Ocean (iFADO) project recently held in The Azores, Portugal. The Slocum glider, Laochra na Mara, can reach depths of 1,000m and collects oceanographic data on conductivity, temperature, depth, fluorescence, turbidity and dissolved oxygen. The glider was deployed from the RV Águas Vivas, and a number of researchers were invited to join and assist from a nearby vessel, RV Arquipélago. Prior to deployment, the glider was exhibited to the public at... (read more)

Multiplexers Simultaneously Transmit Data Along a Single Communication Channel

MacArtney, headquartered in Denmark, has recently supplied the latest in a series of seven customised NEXUS MK C ‘Super MUX’ multiplexers to MMT, providers of customised marine surveys for the offshore energy industry. Multiplexers, designed to simultaneously transmit data along a single channel of communication, provide operators with the opportunity to gather numerous types of data at once. The Swedish based, MMT working in close collaboration with Reach Subsea, ordered the customised NEXUS MK C connectivity solution (named the Super MUX by MMT) from MacArtney Underwater Technology earlier this year. Offshore Energy Industry MMT assists the global industry with a range... (read more)

How to Carry Out an Asset Inspection Survey

Bibby HydroMap, a UK-based company, has successfully completed an asset inspection survey of several bridges and the Weaver Sailing Club along the River Weaver in Cheshire (UK). This was an opportunity to demonstrate its marine 3D imaging capabilities in a highly dynamic and fast-flowing environment. The River Weaver is a marine connection between a number of businesses along the river and the Manchester Ship Canal and, ultimately, the Irish Sea, the integrity of which is paramount to their commercial operations. Locate Any Obstructions to Navigation The aim of the survey was to assess the condition of the bridges which span the... (read more)

What is the Impact of Submarine Volcanoes on Biological Activity at the Ocean Surface?

An international team of 29 researchers will plough through Pacific waters between NoumeĢa and the Tonga volcanic arc from 1 November to 5 December 2019 aboard l'Atalante, an oceanographic research vessel. The aim of this campaign, dubbed the TONGA Project, is to study the effects that shallow submarine volcanoes have on marine life. Coordinated by two women researchers from the Oceanographic Laboratory of the Institut de la Mer de Villefranche (CNRS / Sorbonne University) and the Mediterranean Institute of Oceanography (CNRS / IRD / Aix-Marseille University / University of Toulon), the TONGA Project brings together nearly a hundred scientists from...

TerraSond Completes First Geophysical Survey for Mayflower Wind

TerraSond, an Acteon company, has completed a high-resolution geophysical survey for Mayflower Wind, a joint venture between Shell New Energies US LLC and EDPR Offshore North America LLC. The two-month campaign, which began in July 2019, surveyed an area, 20 miles south of Martha’s Vineyard, Massachusetts, USA, that can support up to 1,600 MW of offshore wind. The wind farm is scheduled to deliver energy in the mid-2020s and has the potential to power up to 680,000 homes. The project is TerraSond’s first with Mayflower Wind. High-resolution Geophysical Data TerraSond acquired high-resolution geophysical data using a complete suite of equipment in... (read more)

How Does the Poggy, the New Bionic AUV, Operate?

EvoLogics from Berlin, Germany, has introduced Poggy - a novel, bionic autonomous underwater vehicle that uses Fin-Ray® technology. The vehicle is being developed as part of the BONUS SEAMOUNT collaborative R&D project and made its first dives at the Breaking The Surface 2019 workshop in early October. Nicknamed Poggy, the AUV is one of a kind; a novel, bionic design with two propulsion thrusters and two independent flexible 'tails' that give the robot mobility features. Its dual-tail construction is an original idea that stemmed from previous work on EvoLogics’ Manta Ray AUV and its lifelike 'flapping wing' propulsion system. The design... (read more)

Fugro Completes Deepwater AUV Surveys for Shell in US Gulf of Mexico

Fugro has completed several high-resolution geophysical surveys in the US Gulf of Mexico for the Shell International Exploration and Production Company. The project required data collection over multiple deepwater lease blocks in the greater Perdido and Mars development areas to support clearance of potential environmental, engineering, geological and archaeological hazards ahead of planned drilling activities. As the preferred contractor for this project, Fugro deployed a Hugin autonomous underwater vehicle (AUV) from its purpose-built survey vessel, the Fugro Brasilis. The Hugin AUV is depth-rated to 3000m and equipped with a multibeam echosounder, side-scan sonar and sub-bottom profiling sensors. As such, Fugro... (read more)

WASSP Launches New Rapid Deployment Multibeam Sounder

WASSP Multibeam has launched its new rapid deployment multibeam sounder – the W3 Rapid Deployment System (RDS). Revealed at the recently held Pacific Expo 2019 in Sydney, Australia, W3 RDS has been designed for navies, maritime police and search & rescue organizations for use where depths are unknown and to find safe navigation routes for larger vessels. When a fixed transducer installation in a small vessel such as a tender isn’t always practical, the W3 RDS has been designed around a portable Carbonfibre Mast that includes a transducer, motion sensor and satellite compass. This allows operators to deploy the unit... (read more)
