Sonardyne Leads AUV Collaboration Project

Positioning for Persistent AUVs (P3AUV) project is to enable AUVs to operate at high levels of navigation performance with less surface support and for longer periods.The provider of underwater acoustic, inertial, optical and sonar technology said in a release that with partners L3 ASV and the National Oceanography Centre (NOC), Sonardyne will focus on longer-term navigational accuracy for AUVs in deep water, while reducing power requirements and increasing autonomy in marine operations.The P3AUV project will involve trials using Sonardyne’s leading underwater positioning technology on the NOC&rsquo

Whale Tracks Found in Areas Targeted for Deep-sea Mining

depressions forming mysterious “tracks” on the seafloor may be an unprecedented record of deep-diving whales. The observations were made by an autonomous underwater vehicle (AUV) in a region of the Pacific Ocean targeted for deep-sea nodule mining, as part of a new study led by the National Oceanography Centre (NOC) and the University of Southampton.Initially perplexed by the mysterious tracks, researchers concluded they were not related to mining or scientific operations within the area; they appeared too large to be created by fish or any other typical deep-sea animals; and they were not thought

NERC Purchase NORBIT WBMS Systems for AUV Project

Seeking a robust system that has been proven for under-ice mapping, the National Environmental Research Council (NERC) has appointed NORBIT to supply two multi-beam echosounder (MBES) sonar systems for use on the National Oceanography Centre’s (NOC) new 2,000m depth rated AUV platform Autosub2KUI.With the small form factor WBMS Deep Water multibeam systems, NORBIT’s systems will ensure high data quality and ease of operation for the team at NOC often operating in challenging environmental conditions, the manufacturer said.This will support future under-ice and deepsea science, including a

Symbiotic Autonomy for Deep Water Survey

Marine technology partners have developed a new long endurance, multi-vehicle, autonomous survey solution.ASV Global (ASV), in partnership with Sonardyne International Ltd., the National Oceanography Centre (NOC) and SeeByte, have delivered a long endurance, multi-vehicle, autonomous survey solution after a two-week trial in Scotland’s Loch Ness. The tests were the culmination of the three-year ‘Autonomous Surface and Sub-surface Survey System’ collaborative project, part-funded by Innovate UK and Dstl, which set out to produce an integrated system to perform low cost, full water

NOC Predicts Increase in Extreme Sea Levels

generate storm surges and high wind waves. These incidents are intensified by gradual rises in mean sea level and predicted increases in tropical cyclone activity. Researchers have taken all these factors into account to assess future risks of extreme sea levels up until the year 2100. The National Oceanography Centre (NOC) was part of the research team that published this new study in the scientific journal Nature Communications. One finding showed that extreme sea level events that occur about once every 100 years, would occur almost annually along most global coastlines by the end of the century

, we are also hoping that national hydrographic organizations will start sharing their data and closer to shore," Bindra said.Bindra said the data obtained from the multiple sources would be pulled together by experts at four centers around the world and then collated at Britain's National Oceanography Centre, adding that they planned to produce their first bathymetric map by the end of 2018 and update it annually.Peter Thomson, the U.N. secretary general's special envoy for the ocean, said he was "very aware ... of the mineral aspects" of exploring the seabed, adding that the

They’ll also make detailed measurements of litter and plastic accumulation in the open ocean.Led by the National Oceanography Centre (NOC), the seagoing team will use a variety of tools including instruments fixed to a floating buoy, specialized sediment traps to collect sinking particles, and samplers of the water and the seabed three miles beneath the surface. The team will use these sediment traps and samplers to

AUV Tracking System Tested in Loch Ness

AUV provides status updates and basic survey information back to the ASV to be transmitted to shore.The project team involving software company SeeByte; provider of underwater acoustic, inertial, optical and sonar technology Sonardyne; and the marine science research and technology institution National Oceanography Centre (NOC) are carrying out trials in Loch Ness in the Scottish Highlands this week (May 14, 2018).The latest round of testing builds upon the capability demonstrated in two previous trials in 2017.The initial trial in May 2017 saw the C-Worker 5 ASV successfully communicate with, and track

Marine Robots Detect Whales in the Deep Ocean

 A fleet of marine robots built and operated by the National Oceanography Centre (NOC) and its partners has detected whales and porpoises and recorded the sounds they make in a survey of the deep ocean off northern Scotland.   In the summer of 2017 a fleet of 11 autonomous marine robots was deployed to explore the seas northwest of the Orkney Islands in search of marine mammals and sources of manmade noise pollution. The mission was part of an annual series of marine robot trials coordinated by the NOC in partnership with 16 organizations representing U.K. government, research and industry.

It is good for Newcastle University to be involved in this project at this stage. This is the first fieldwork season for ORCHESTRA and we hope that

Oceangoing Lab: The Real Test of a Nutrient Analyzer

 The U.K.’s National Oceanography Centre (NOC) undertakes integrated ocean research and technology development from the coast to the deep ocean. As such, the NOC has a heavy requirement for seawater analysis. However, in addition to analytical work at the NOC’s facilities in Southampton and Liverpool, the organization’s researchers also need to be able to analyze samples on board a variety of research vessels. Under these conditions, high levels of precision and reliability can be a challenge for most laboratory equipment, so NOC has invested in SEAL Analytical segmented flow

Zooplankton Behavior Helps Solve a Carbon Cycle Mystery

A key piece of the carbon cycle puzzle has been solved by scientists from the National Oceanography Centre (NOC), with the discovery of the mechanism underpinning more efficient carbon transfer in low oxygen zones. This research, published in Nature Communications, suggests that the observed increase in efficiency is due to changes to zooplankton activity in low oxygen zones.   The storage of carbon in the ocean has a regulating effect on the climate and is increased by the sinking of tiny carbon-containing particles from the surface ocean. More efficient sinking in low oxygen zones has been
