to seabed.The researchers will track the flow of the greenhouse gas carbon dioxide from the air into the surface ocean, and the eventual fate of this carbon in the ocean depths. 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

.”   Within the last decade, interest in UUVs as part of specific military, industrial and academic missions and applications have increased due to technological innovations and the evolution of their sensor payloads. Missions such as persistent surveillance, anti-submarine warfare, oceanography and mine countermeasures are among key advantages of utilizing UUVs as compared to other platforms. The U.S. Navy has identified several major benefits of unmanned vehicles in maritime surface and sub-surface applications. They are far less expensive to operate and maintain than manned vehicles

Wave Gliders to Study Arctic and Southern Oceans

will deploy long duration unmanned ocean robots called Wave Gliders as a sensor platform to conduct advanced scientific research in inhospitable and remote regions of the Arctic and Southern Oceans.Using Liquid Robotics’ wave and solar powered Wave Gliders, scientists from Scripps Institution of Oceanography (Scripps) and the Applied Physics Laboratory of the University of Washington (APL-UW) will obtain real time data and rare insights into the dynamic conditions that drive the world’s weather and climate. This data is critical for scientists to understand and improve global ocean weather modeling

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. The

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

The results of this investigation will help improve understanding of how the ocean’s biology contributes to the long-term storage of carbon in the ocean.The National Oceanography Center (NOC) will lead this expedition to the Benguela upwelling region of the South Atlantic, where cold, nutrient-rich water rises to the surface, providing the food to fuel large blooms of tiny marine plants, called phytoplankton.The science conducted on this latest expedition forms part of

AIRMAR Sensors Offer Optimum Performance for AUVs

The increased demand for maritime systems that can collect information for organizations and governments in sectors such as defense and security, oil and gas, oceanography, and hydrography is driving today’s development of Unmanned Maritime Vessels.   Growth in the commercial exploration segment of the market is attributed to the expanding use of Autonomous Underwater Vehicles (AUVs) and Autonomous Surface Vehicles (ASVs) in applications such as surveys and seabed mapping, offshore drilling, and pipeline inspection.   “We’ve experienced considerable growth in our

New Range of Underwater Connectors

Immersible connectors have to meet a variety of mechanical and chemical constraints. SOURIAU has been active in this market for a very long time, continuously adapting its product range to customer requirements in the field of military submarines, oceanography, geophysics and the oil industry. With SWIM, SOURIAU is launching a new range of connectors designed for new markets.The new SWIM range (Shallow Water IMmersion) is designed for marine applications in depths down to 300 m, which are considered shallow immersion. These connectors are designed for innovative applications like surface drones for
