Operation of marine survey vessels in shallow-water coastal environments is a dangerous endeavor. A subsurface obstruction can tear a multi-beam sonar from its tow cable, resulting in loss of the expensive device and potential delay in the expedition. Lost equipment, however, is a minor inconvenience compared to the equally real possibility of the ship running aground in poorly charted waters, endangering the safety of its crew and incurring millions of dollars in damage.For this reason, survey vessel operators invest considerable time and money to minimize the risk involved in each voyage.

Wave Buoy Measurements on a Hexapod

MARIN has recently expanded its facilities with a hexapod. This system can be used to generate forced oscillations in six degrees of freedom, either on a standalone basis or under the carriage of one of our basins. It is a useful tool to assess the efficiency of anti-roll tanks, sloshing in liquefied natural gas (LNG) tanks, safety of cruise ship swimming pools or drop tests with a free-fall lifeboat from a moving platform.   As the positioning system of the hexapod is very accurate, another useful application is the validation of measurement equipment. Recently, MARIN used it to evaluate the

Ocean Microstructure Glider Workshop Announced

Rockland Scientific and the Bermuda Institute of Ocean Sciences announced a specialized training program for Rockland turbulence measurement systems that are integrated with ocean gliders.   Ocean Microstructure Glider (OMG) 2018 will be hosted by the Mid-Atlantic Glider Initiative & Collaboration (MAGIC) at the Bermuda Institute of Ocean Sciences St. Georges, Bermuda from May 28 to June 1.   Classroom and field training will be optimized for both scientists and technicians and facilitated by instrument specialists from Rockland Scientific.   Fees to attend OMG 2018 are $1

Expanded Waterfront for Oi18

Visitors to Oceanology International 2018 (Oi18) at ExCel, London (March 13th-15th ,2018), will once again be able to participate in a series of live product demonstrations from the event’s waterside exhibitor area on the Royal Victoria Dock. As one of the most popular attractions for Oceanology International visitors, this year’s dockside and on-water demo programme has been expanded and will now comprise daily demonstrations to offer an even more valuable experience for those attending, whilst allowing exhibitors to share their product’s effectiveness in a marine environment.

University of Vienna Acquires New Multibeam Equipment

A project to create 3D models of pile dwellings in Austrian lakes thousands of years ago has resulted in the acquisition by the University of Vienna of a multibeam solution supplied by MacArtney.   The Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology is a research institute dedicated to the development of new techniques and methodological concepts for landscape archaeology. Its research program combines geophysics, aerial imaging, computer science and geomatics to develop efficient and universally applicable approaches for non-destructive detection, documentation

fraction of the cost of other AUVs. Through PicSea, Durrant aims to make underwater data more accessible to those within the scientific community that lack access to large budgets or advanced technological resources. Durrant said, “There’s a very limited subset of people who not only want ocean data but can afford access to AUV technology. For example, I know a group of biologists who want to carry out lots of environmental surveys using AUVs, but their budgets just don’t allow for it. This sort of thing is widespread across the scientific community, and it’s something I am
