New Tech Deployed to Study Harmful Algal Blooms

A new research project aims to evaluate the potential efficacy of ultrasonic technology to mitigate harmful algal blooms (HABs) on Lake Agawam, village of Southampton.HABs are a growing environmental problem, affecting all parts of the world. Excessive nutrient pollution entering water bodies, especially phosphorus and nitrogen, drive the growth and spread of harmful algal blooms. Besides unpleasant tastes and odors, excessive HABs can seriously harm humans, pets, and aquatic organisms, and degrade water quality. Additionally, they can disrupt water treatment processes by clogging filters and pipes.

But even such remote stretches of international waters face increasing incursions from shipping and industrial fishing.In March, scientists from institutions including Britain’s

The James River is a tributary of the Missouri River. It is roughly 710 miles long and spans over 20,000 square miles of North and South Dakota with more than 70% of the river’s drainage occurring in South Dakota. River conditions during normal years include both still-water and flooding on both the James River and its tributaries. Water easily breaches the low banks, and these floods tend to cover a significant portion of the floodplain. When the river is still, water quality drops and it becomes quite difficult to see more than a few feet underwater.The Beadle County Office of Emergency

Autonomy: Inside the Building of Ocean Infinity’s Armada Fleet

made a novel move; deploying six autonomous underwater vehicles (AUVs), instead of just one, from a single vessel, vastly increasing the ground that could be covered in a single survey. Now the firm is taking the use of remote, robotic systems a significant step further.As we enter 2021, US-UK based marine robotics firm Ocean Infinity is launching the start of what will become a fleet of completely uncrewed ocean going vessels, or USVs. They will host and deploy other robotic systems, including remotely operated vehicles (ROVs) and AUVs, as well as towed systems and full ocean depth survey equipment

Discovery: Uncovering Manta Ray Behavior via Mini ADCP

Understanding why marine animals are using some places and not others is crucial to minimizing our impact on them. Recently, the new Eco ADCP has been helping one marine biologist, with no previous experience in using oceanographic instruments, characterize current flows in one of the manta ray‘s more unusual shallow-water coastal habitats with simplicity and ease.Powerful yet graceful, manta rays top almost everyone’s list of must-see marine animals. While people flock to places like Indonesia or the Maldives to watch these gentle giants, one location has gone relatively unnoticed –

Orange Marine Orders Cable Repair Vessel

French submarine cables services company Orange Marine has ordered a new cable repair vessel for delivery in 2023.The specialized newbuild was designed by VARD in Norway and will be built at Sri Lankan shipyard Colombo Dockyard. The 1,800 dwt vessel is 100 meters long with a beam of 18.8 meters and a depth of 7.15 meters. It will have accommodation facilities for 76 persons.The VARD 9 03 design for Orange Marine is designed for the maintenance of submarine cables, both fiber-optic telecommunication cables and inter-array power cables used in offshore wind farms.The eco-friendly vessel features a

More GoM Work for Magseis Fairfield

Oslo-listed Magseis Fairfield on Friday said it had won a deep-water 4D Ocean Bottom Node (OBN) monitor survey contract in the US Gulf of Mexico with a repeat customer.The survey will be conducted with Magseis Fairfield’s ZXPLR technology, currently in use for ongoing projects in the same region. The start-up is expected to be mid-Q2 2021, and the project will run for approximately two months.“We are glad to see our customers recognizing the value we bring, and award us repeat business. This contract represents an important addition to our overall backlog, and specifically extends our

Series of High-res Surveys to Track Changes in Thames River

A two-year project aims to locate and monitor the shifting boundaries of key biological habitats and short-term, small-scale changes in bathymetry important to the health of Connecticut’s Thames River and Long Island Sound ecosystems. Marine technology company ThayerMahan, which recently completed an underwater survey using its SeaScout system to capture high-quality hydrographic imagery of the river, said the survey is being conducted under a National Institute for Undersea Vehicle Technology (NIUVT) project in conjunction with the University of Connecticut (UConn)’s Department of

Autonomous Navigation – with or without GNSS

current optimally without GNSS significantly reduces the risk of performing ROV and AUV deployments from USV host platforms.A good example of this is the Armada fleet, being built by Ocean Infinity. The first wave of the fleet will host our Ranger 2 Ultra-Short BaseLine (USBL) positioning system and Marine Robotics pack, which will enable all-in-one tracking, communications and control capability for underwater payload robotics from the Armada vessels. In addition, the vessels will be fitted with SPRINT-Nav, to provide continuous, uninterrupted navigational aiding to underpin safe remote operations
