USVs: A Solution for Inspecting Dams and Guarding Waterways

MBARI: Hydrothermal Mapping is Heating up

A recent paper by Monterey Bay Aquarium Research Institute (MBARI) has revealed almost 600 hydrothermal chimneys around the Endeavour Segment of the Juan de Fuca Ridge, about 350 kilometres (220 miles) northwest of Washington State. The vents, located in a valley about 14 kilometres (8.6 miles) long and 1.5 kilometres (0.9 miles) wide, has been studied previously, but never mapped until now because of difficult access.Hydrothermal vents are created by magma beneath the seafloor that heats water within the surrounding bedrock, emerging from the seafloor in the form of underwater seeps and geysers.

Fast-moving Waterfalls in the Deep Sea

New research led by the National Oceanography Center (NOC) has discovered how fast-moving waterfalls under the sea control the shape and behavior of submarine channels. These underwater channels are the offshore equivalents of rivers, but can be much larger. Submarine channels can extend for tens to thousands of kilometers offshore, providing an important conduit for the transfer of sediment, nutrients and pollutants, such as microplastics, to the deep-sea. Avalanches of sediment that flow down these channels also pose a hazard to networks of seafloor cables that underpin global communications,

This can apply when proper identification and measurement of features is critical to risk management, and to a greater extent in situations where there will be close interaction with the surveyed objects. When performing marine salvage, construction, or asset inspection, it is critical to have the most comprehensible and accurate representation of the data.These applications highlight the differences between historical usages of mesh structures, and the new techniques now being introduced.

and clothing. These are not effectively filtered out in domestic wastewater treatment plants, and easily enter rivers and oceans. In the ocean they either settle out slowly, or can be transported rapidly by episodic turbidity currents – powerful underwater avalanches – that travel down submarine canyons to the deep seafloor (see the group’s earlier research in Environmental Science & Technology). Once in the deep sea, microplastics are readily picked up and carried by continuously flowing seafloor currents (‘bottom currents’) that can preferentially concentrate fibers

Fugro Hired for Abadi Field Survey

Dutch offshore survey firm Fugro has won what it says is "a large marine survey contract" with Inpex offshore Indonesia.Fugro has been contracted to carry out geophysical and geotechnical surveys and the associated studies needed to support front-end engineering design (FEED) for offshore production facilities and the submarine pipeline to the onshore LNG terminal.This is in support of the Abadi gas field development in the Masela Block, in the Arafura Sea.Geo-data will be acquired using Fugro’s deepwater autonomous underwater vehicle (AUV) Echo Surveyor and the company's robotic

Hybrid Hydrographic Boat Delivered in France

French builder Alumarine Shipyard has delivered a new hydrographic survey boat to the Port of La Rochelle.The eight-meter aluminum vessel, dubbed Cassiopée, is powered by a dual electric/diesel propulsion system. The newbuild is designed to transit at 20-25 knots under diesel power between the home port and the acquisition area, then shift to the electric outboards while performing scans of the seafloor.Electric propulsion and hybrid drives manufacturer Torqeedo said it worked closely with the naval architect and shipyard to specify, install and integrate the electric propulsion package consistin

Teledyne CARIS to Display AI Sonar Noise Cleaning Platform at OI

; SIPSTM 11.3 software.At Oceanology International , there will be live demonstrations of noise cleaning using the CARIS Mira AI platform. Visitors to the CARIS booth are invited to “bring the noise” and have their data cleaned on the spot.Teledyne Optech will also be on hand to discuss its marine lidar surveying solutions. Learn about the advantages of the Optech Polaris terrestrial laser scanner that can operate from small watercraft, making it an excellent low-cost tool for mapping shorelines, checking oil rig stability, and surveying the underside of bridges.Live on-boat demos will showcase

Pipeline IMR: An All-seeing Eye

offer the fastest fast way to environmental compliance and maintenance assessments over large areas.Speed is essential, for an environmental impact assessment survey — for an oilfield, a pipeline or a salmon farm — is only the start of site work. These early steps could entail photographing marine biology over an area that could comprise hundreds of kilometers (for a pipeline survey) or just a square mile for a salmon farm. For inspections of existing pipelines or other subsea infrastructure by ROV or UAV, the market offers no all-in-one survey tool of biology and pipeline health: bathymetric

Forum ROV to Support Arctic Research

research icebreaker CCGS Amundsen. In 2020, it will be deployed at several locations spanning a latitudinal gradient from 58° to 77°N to study deep-water corals and cold seep eco-systems of the northern Labrador Sea and Baffin Bay. The project will generate critical knowledge of biodiversity and marine habitats needed for key ocean conservation initiatives in Canada”, said Dr. Alexandre Forest, Executive Director of Amundsen Science.The new Comanche ROV will be manufactured at Forum’s facility at Kirkbymoorside, Yorkshire and delivered in the first quarter of this year

Study: How Changes in Shipping Patterns Affect Whales

work began in La Jolla, California, at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center.  There she developed models to map the spatial distribution of many ocean species, helping the U.S. Navy plan training exercises so that they minimized impacts on marine life.On the East Coast, since the Gulf of Maine is warming faster than most of the world’s oceans, whale feeding patterns and distributions are changing. As water temperatures rise, some whales are moving farther north to find food. These changes could expose them to new risks, including increased
