The Politics of a Subsea Data Cable Link to Antarctica
the highest density of research stations, which is being developed through funding from Multilateral Cooperation Center for Development Financing and CAF Development Bank of Latin American and the Caribbean.These cables would facilitate greater research data transfer that is not reliant on satellite communications.As the Southern Ocean, including the climate-critical Antarctic Circumpolar Current, remains less researched than other bodies of water, a sensor-equipped cable would also provide a valuable platform for sustained seafloor observations and scientific data generation.However, such cables could

optical interface to interrogate the OD OBNs, as developed under a separate ANP program sponsored by Shell.This AUV data harvesting approach eliminates the need for node recovery, reducing vessel time, operational complexity and associated costs.Key Sonardyne technologies include wireless acoustic communications, required for long range recording control and node clock time offset measurement, and Sonardyne’s BlueComm extremely high-speed optical communications for short range data harvesting to a nearby AUV or remotely operated vehicle (ROV).ResultsOver 2,000 days of trials of pre-production nodes
LEO Satellite Networks: Supporting Maritime Safety, Efficiency and Innovation
and shore-based teams with greater situational and operational awareness throughout voyages.However, unlike many onshore industries that are already benefitting from improved data availability, the maritime sector still faces significant barriers, primarily due to slow and often unreliable at-sea communications. More timely access to data is particularly critical to translating data-driven insights into real-world benefits and fostering industry innovation. To enhance vessel connectivity and overcome this challenge, there has been growing interest in the use of low Earth orbit (LEO) satellite networks
Intruder Alert: Ports Face a Range of Underwater Threats
an important component of this deterrent posture, providing a visible presence that discourages unauthorized activity, as well as a rapid response capability. Surface operations may also contribute to underwater surveillance, as radar, EO/IR sensors, or human observers might detect UUV wakes or communications masts, particularly during calm water conditions.Physical barriers provide another important deterrent. Floating security booms are widely used to restrict access to sensitive areas of ports and naval bases. These systems typically consist of surface pontoons connected by cables with mesh netting
Marine Technology TV Discusses Latest ROV Trends
, logistics and lifecycle expectations.”User experience holds enormous weight for customers shopping for underwater vehicles. Systems need to be efficient, customizable and ultimately useful for the desired work. “Customers want systems that can handle uncertainty, operate with limited communications, and integrate smoothly into broader maritime forces that include crewed ships, aircraft and other unmanned platforms,” said Fotheringham. “They're also looking for reduced operator burden.”Also in the issue, Amir Garanovic, managing editor of Offshore Engineer, takes a
Cellula Robotics Selects Sonardyne for Long-Range AUVs
positioning technology for its long-range autonomous underwater vehicle (AUV) platforms.The company has ordered multiple Sonardyne SPRINT-Nav X navigation systems - Sonardyne's highest grade and underwater navigation system.The company has also selected Sonardyne’s AvTrak 6 for tracking, communications and mission control. Part of the package/purchase is multiple Sonardyne Ranger 2 Ultra-Short BaseLine (USBL) positioning and communications systems for both AUV end users and demonstration and testing.“Our users need certainty,” says Richard Mills, Cellula’s Chief Commercial
RS Aqua Launches Marlin Acoustic Monitoring System
with alerts delivered directly to end users. Its modular, scalable architecture supports both fixed and mobile deployments and is compatible with NATO STANAG protocols.With integrated 4G as standard and plug and play options including 5G, Starlink, point-to-point radio and Iridium satellite communications, Marlin is built to operate wherever the mission demands.Marlin has been developed to support a wide range of applications, from real-time marine environmental monitoring and long-term ecological research to remote asset surveillance and security-critical maritime operations
RS Aqua Announces Strategic Partnership with US -based Seasats to Bring Autonomous Surface Vehicles to UK and Ireland Defence Market
addresses the growing need for coastal security against surface, subsurface, and sUAS threats that are becoming a prevalent global problem. In partnership with RS Aqua, the Quickfish will be provided in the UK to accelerate domestic maritime security capabilities.Core Capabilities:Multi-modal communications: Starlink, Iridium, cellular, MANET radiosRedundant sensor package: Marine radar, HD and thermal cameras, AIS broadcast/receive, LiDAROpen systems architecture for integration with third party C2 platformsBrowser-based UI operable via secure tablet, laptop, or mobile deviceLaunch/recovery in
Sonardyne Launches Intelligent Subsea Monitoring Tool
technology specialist Sonardyne has launched Observer, a new advanced monitoring system for real-time integrity management of subsea infrastructure across the offshore energy industry.Observer combines high and low frequency motion and position monitoring, powerful in-built analytics and wireless communications to deliver live insight into how subsea assets are truly behaving.This means unseen process and environmental challenges, from pipeline expansion and contraction to vortex and flow induced vibration, can be addressed before they become a problem, lowering risk and intervention and costs, while
