.“That’s where robotics are really good,” says Prof Cottier. “They’re limited by batteries but are very useful, so there’s desire to use them more in these areas, especially in difficult (seasonal) windows.”  But, there’re trade-offs. How much instrumentation you take limits mission length due to battery capacity. What’s more, in arctic waters, the freezing temperatures also drain batteries faster than in warmer waters, points out Dr Porter. With few recovery options in the area – the nearest port being 24 vessel steaming hours away &ndash

, their evolution has been rapid in recent years. New array designs, ever increasing diversity in frequency range, and novel configurations have come on scene quickly. Innovations inspired by current consumer tech, including apps and cloud computing are exciting developments not often seen in ocean instrumentation. But the demand for measurement of water’s motion is significant and drives equally significant innovation. The next decade of movement will be exciting.The Tasman DVL employs a single, phased array (Photo Courtesy Teledyne Marine

Seatool’s Plug-and-Play Subsea HPU Range

powerpacks were designed to meet the demands of today’s subsea equipment and clients’ configuration requirements, and come with a significant number of (integrated) hydraulic system components and functionalities. Examples are pressure compensation, filtration, controls, and instrumentation. The modular approach creates a benefit for hydraulic system integrators: a cost-efficient configuration of subsea hydraulic systems that matches the specific requirements of integrators, while pushing the limits of system compactness and reliability.The new range is specifically designed for

Change of Management for Nortek

After over two decades at the helm of Nortek, a specialist in oceanographic instrumentation, Atle Lohrmann is taking on new challenges at newly started Hefring Engineering in Boston. Nortek’s new CEO, Finn Ivar Marum, has been entrusted with the task of ensuring Nortek’s continued growth.Nortek was established in 1996, when Atle Lohrmann set up offices outside Oslo, Norway, and started building up production capacity for Doppler instrumentation.Since then, Nortek has grown rapidly, with its revenues increasing from $985,000 in 1996 to $24.6 million in 2018. Many factors lie behind the

Soreide)."With this project, we are pioneering a cost-effective and flexible platform for gathering data that will help safeguard the health of the ocean and the industries it supports," he added.The vessel will carry three research pods containing an array of sensors and scientific instrumentation that scientists will use to advance understanding in a number of vital areas such as maritime cybersecurity, marine mammal monitoring, sea level mapping and ocean plastics. The work will be coordinated by the University of Plymouth, UK, who are at the forefront of marine and maritime research

equipment not only more capable, but also simpler to use and, ultimately, to help make survey operations, ocean observation projects more efficient.Examples include Fusion 2, which supports both LBL and INS operations and reduces hardware requirements. SPRINT-Nav combines inertial, Doppler and depth instrumentation and capability into one compact, low power unit, increases navigational precision and frees up valuable payload for additional mission sensors.The company’s sixth generation hardware remains a highly regarded choice for positioning, tracking and autonomous monitoring applications.

AML MVP to Augment NSCC’s Seafloor Mapping

to add ground-truthing to the process of multibeam data acquisition, AML and NSCC are working together to integrate lights and a high-resolution camera to the tow body that houses the underway profiling system’s sound velocity (SV), conductivity-temperature-depth (CTD), or multiparameter instrumentation. Ground-truthing is a critical step in validating the seafloor characteristics (e.g. seafloor sediments and habitats) for interpretation of seafloor mapping multibeam data.Dr. Craig Brown, NSERC Industrial Research Chair in Integrated Ocean Mapping Technologies, will be leading the project.

that we truly never expected. About 30 minutes after Nathan first saw the squid on the screen, lightning struck the ship.A close lightning strike is an impressive experience. One that strikes the metal boat that is your only home, and that you are currently inside of, is scary. It struck a starboard instrumentation antenna only a few feet from the people on the bridge and just a bit further from the people in the remotely operated vehicle (ROV) van on the bow.Those of us on the main deck immediately ran to the Medusa computer to see if it was destroyed.

A New USV for Ocean Surveying

A new unmanned surface vehicle (USV) designed for the Chinese market offers an open and low-cost platform to measure water current and direction. Nortek China has integrated Doppler instrumentation on the vehicle to help better meet user requirements for ocean surveying.The new USV has an IPC (Industrial Personal Computer) as the main operation platform and uses Remote Desktop, a remote control technique, to communicate with all the instruments installed. This means that the vehicle offers an open and low-cost platform for customers who need to carry out several different tasks at the same time.
