Underwater Fire - Exploring Submarine Volcanoes

 Photos provided by Schmidt Ocean Institute

Most of Earth’s volcanoes are in the oceans, yet scientists know very little about them compared to volcanoes on land. Schmidt Ocean Institute’s research vessel Falkor recently completed a 41-day expedition near Tonga, using cutting-edge technology to map, view, and sample underwater volcanoes while sharing observations with the public using real-time video streaming and chat programs. Findings include detecting widespread evidence of deep sea explosive volcanism, observing one of the rarest volcanic rock types on Earth…

Research Shows Iron's Long Ocean Journey

A new study led by scientists at the Woods Hole Oceanographic Institution (WHOI) points to the deep ocean as a major source of dissolved iron in the central Pacific Ocean. Researchers found that iron can travel long distances, highlighting the vital role ocean mixing plays in determining whether deep sources of iron reach the surface-dwelling life that need it to survive. Iron is readily soluble in low oxygen regions at hydrothermal vent sites and along continental margins, but it was believed iron remained in these localized spots and contributed minimally to the ocean's overall iron content.

Schmidt Ocean Institute’s research vessel Falkor returns from the first ever expedition to systematically characterize the rarely explored Mariana Back-Arc. HAGANTA, GUAM – A diverse team of scientists are returning from a 28-day expedition onboard R/V Falkor that has more than doubled the number of known hydrothermal vent sites in the Mariana Back-arc region. This area, west of the Mariana Trench, is where plate spreading and submarine volcanism are concentrated. Several momentous findings were made, including the discovery of one of the deepest vents ever found.

Sonardyne helps major scientific discovery on the Mid-Atlantic Ridge

A Sonardyne Wideband Mini-Transponder was installed on the Holland 1 ROV and also on its tether management system.

Sonardyne International’s Ranger 2 USBL (Ultra-Short BaseLine) acoustic positioning technology has played a crucial role in a scientific mission to discover a new eco system on the floor of the Atlantic Ocean. The Irish led VENTuRE expedition used the Ranger 2 equipment to track the Remotely Operated Vehicle (ROV) Holland 1 over three kilometres below the sea surface as it searched for and filmed evidence of the newly named Moytirra Vent Field. The mission to find and study the deep sea vent field on the mid Atlantic Ridge was undertaken from the Irish research vessel, RV Celtic Explorer.

Chinese Submarine Dives into Indian Ocean

China's submersible Jiaolong

A Chinese submarine has started to search an area of the Indian Ocean for seabed deposits of gold, silver, copper and zinc, in a four-month-long mission. A Chinese submersible vessel has been conducting its first deep dive in the Indian Ocean in search of rare metals. It will collect samples of hydrothermal fluid and sulfide, which is a kind of seabed deposit that contains copper, zinc and many precious metals such as gold and silver, official Xinhua news agency said. The project, which involves exploring the Indian Ocean for 120 days, reflects China's hunger for resources, sources say.

Japan has unveiled a 6,283-ton exploration vessel that will search for rare metals and other natural resources in waters around the nation. The Hakurei, 118 meters long and 19 meters wide, was shown to the media at Harumi Wharf in Tokyo. The vessel features drilling equipment that can dig up 400 meters into the seabed at a depth of 2,000 meters. The ship will initially search for resources off Okinawa Prefecture and the Ogasawara Islands. The Hakurei is owned by the government-backed Japan Oil, Gas and Metals National Corp.

A deep-sea exploration robot — one of the first successful submersible vehicles that was both unmanned and untethered to surface ships — was lost at sea Friday, March 5, on a research expedition off the coast of Chile. The 15-year-old Autonomous Benthic Explorer, affectionately nicknamed ABE, was launched late on the night of Thursday, March 4, and had reached the seafloor to begin its 222nd research dive when, in the early hours of Friday morning, all contact with the surface vessel abruptly ceased. All efforts to reestablish contact failed.

WHOI Awards Lockheed Martin $2.8m Contract To Design RHOV

Langh Tech’s new generation of water treatment systems has been launched with upgraded membrane technology to increase water cleaning capacity. In 2017, Langh Tech launched a second generation of water treatment systems based on a new type of membrane filter elements. With the new elements, Langh Tech said a 50 percent increase in water cleaning capacity can be reached compared to the previous elements, without increasing the size of the water treatment units. The new membrane elements has been tested onboard Langh Ship’s M/S Marjatta from the first half of 2017…

Regional Route Sharing Introduced in Baltic Sea

VTS centres receive route information via radio contact and will then have to either plot it into their own system or not. With the new integration scheme, they can receive a full visualization instantly. Map: EfficienSea2

Maritime digitalization carried out in the European project EfficienSea2 has enabled effective route sharing between different VTS systems in the Baltic Sea. It has the potential to drastically cut the reporting effort for the ship’s crew, while offering authorities a better ability to ensure safe traffic at sea. The days may soon be over when mariners have to pick up a radio to take on the cumbersome task of reporting their vessel and route parameters every time they cross into a new VTS area – at least for those sailing in the Baltic Sea.

Growing interest in hybrid-electric power systems is expanding the search for new propulsion and energy-storage systems in the workboat sector, where compliance with emerging environmental regulations and a relentless pursuit of operational efficiency are driving change. To meet demands for cleaner more efficient power, owners are examining the potential for less conventional methods of energy generation and storage – such as fuel cells, lithium-ion batteries, super-capacitors, flywheels, wind and solar – to propel their vessels.

The opening of the world's first mine in the deep ocean comes closer to reality as Canadian mining company, Nautilus Minerals, signs an agreement with the Papua New Guinea Government to start excavating an area of seabed. The project will extract ores of copper, gold and other valuable metals from a depth of 1,500m, The mine will target an area of hydrothermal vents where superheated, highly acidic water emerges from the seabed, where it encounters far colder and more alkaline seawater, forcing it to deposit high concentrations of minerals.

The U.K. Royal Navy’s fourth Astute class submarine, Audacious, has completed its first ever dive, marking a milestone on the path toward full sea trials later in 2018. The trim and basin dive took place over two days in early January in Devonshire Dock, at builder BAE Systems's site in Barrow-in-Furness. The operation, which saw Audacious submerge fully underwater for the first time, allowed a team from Royal Navy, Ministry of Defense and BAE Systems to test many of the sub’s onboard systems, and proved the safety and stability of the 7,400-metric-ton, 97-meter-long attack submarine.

Defense technology company Naval Group and helicopter manufacturer Airbus Helicopters will together lead an effort to develop warship based aerial drones for the French Navy. The French companies were recently contracted by the French Directorate General of Armaments (DGA) to perform a “de-risking” study ahead of future construction of tactical helicopter drones. The demonstration project will eventually lead to trials of the drone launch system, mission system and airborne rotary-wing vehicle, conducted from a French Navy vessel.

Shipowners should take action to reduce the impact of invasive aquatic species (IAS) carried by hull biofouling. The UK P&I Club has published its top tips on how to reduce biofouling on board vessels to achieve greater efficiency and reduce environmental risk. According to Madlene Wangrau, UK P&I biofouling  is the undeseriable accumulation of various aquatic organisms on submerged structures. “Biofouling is undesirable accumulation of various aquatic organisms (microorganisms, plants, algae and animals) on submerged structures like ships’ hulls.

BAE Systems Launches Talisman Autonomous Underwater System

BAE Systems launched its new autonomous unmanned underwater vehicle (UUV) Talisman at Oceanology International 2006. The Talisman System, developed by BAE Systems in the UK, is a latest-generation modular multi-role UUV, capable of a wide range of maritime littoral operations.
