On-Demand Ocean Bottom Node: A New Era in Deepwater Seismic Monitoring
,’ which implements the through-water 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

Green Tech: Rise of the [Hull Clening] Robots
coating life.With fuel costs still representing one of shipping’s largest operating expenses, and international regulatory pressure mounting to reduce greenhouse gas emissions, the commercial case for robotic hull maintenance has never been stronger.The earliest push for in-water hull-cleaning technologies was largely driven by environmental regulation. A short but growing list of countries are expected require visiting vessels to demonstrate that their hulls are free of invasive marine species before entering sensitive waters. Biofouling has long been recognized as a major vector for transporting
LEO Satellite Networks: Supporting Maritime Safety, Efficiency and Innovation
Across the maritime sector, the availability of data has never been higher. Supported by new data collection technologies and advanced analytics, mariners are gaining access to increasingly detailed information on the marine environment. Smart sensors are also becoming more widespread, enabling real-time monitoring of on-board equipment and cargo. Combined, these insights have the potential to provide both mariners and shore-based teams with greater situational and operational awareness throughout voyages.However, unlike many onshore industries that are already benefitting from improved data availabilit
Application Note: Pressure Relief Valves and Purge Ports
. The companies that make them do so with the best interest of the end-user in mind. There are important subtleties to understand for their successful incorporation into subsea equipment. Use a dedicated purge port when one is called for.“Lander Lab” is a hands-on column of Ocean Lander technologies and strategies, a unique class of unmanned undersea vehicles, and the people who make them. It is meant to serve the global ocean lander community in the manner of Make Magazine and other DIY communities.Comments on this article, or suggestions for stories of interest to other Landereans are welcome
Intruder Alert: Ports Face a Range of Underwater Threats
, all without risking human life. Their low acoustic signatures make them difficult to detect in the acoustically cluttered environments typical of busy ports, and they can infiltrate harbors autonomously using advanced navigation systems. And the growing affordability and accessibility of UUV technologies means underwater strike capabilities are no longer limited to specialized military units, and may increasingly enter the toolkit of both state and non-state actors.As these risks grow, coastal installations are increasingly adopting layered security approaches combining deterrence, surveillance

Zelim Opens New Canada Office in Nova Scotia
market. The site will be located at the COVE ocean facility in Dartmouth, Nova Scotia, a major technology hub for maritime innovation.Starting in April 2026, the office premises will serve as a base for Zelim to advance ongoing partnerships and future opportunities in the region for its AI-enabled technologies, which are designed to enhance the safety and security of operations at sea.The move builds on Zelim’s foothold in the Canadian cruise, ferry and defence industries. In 2024 Zelim demonstrated its flagship man-overboard detection and monitoring system, ZOE, to the Canadian Coast Guard and
Teledyne eXtreamer for Seismic Data Receives 2026 Spotlight on New Technology Award
Teledyne Geophysical Instruments, a division of Teledyne Marine, has announced that eXtreamer, its advanced small form factor seismic streamer, has received a 2026 Spotlight on New Technology Award, from the Offshore Technology Conference (OTC). The award recognizes technologies that demonstrate advancement, uniqueness, and commercial impact within the offshore energy industry.Developed in collaboration with Geometrics Inc., eXtreamer addresses the growing demand for ultra-high-resolution (UHR) and ultra‑ultra‑high‑resolution (UUHR) marine seismic data acquisition. The system combines a robust yet
