Antarctic Mountains Could Boost Ocean Carbon Absorption
;s ice sheets thin due to climate change, newly exposed mountain peaks could significantly increase the supply of vital nutrients to the Southern Ocean which surrounds the continent, potentially enhancing its ability to absorb atmospheric carbon dioxide, according to the research published in Nature Communications.A team of scientists with expertise in oceanography, ice sheet modelling and geochemistry contributed to the study which looked at analysis of sediment samples from East Antarctica's Sør Rondane Mountains. They discovered that weathered rocks exposed above the ice surface contain iron
Magnetic Fossils May Reveal Eels’ Internal GPS System
a key part of building a natural 'GPS system,' enabling an animal to actually geolocate itself, not just know, for instance, which way is north," said Rich Harrison, a University of Cambridge professor of Earth and planetary materials and co-leader of the study published in the journal Communications Earth & Environment.A global positioning system provides satellite-based navigation guidance.While some migratory animals including birds, fish and insects are thought to use Earth's magnetic field to navigate, how they manage this remains unanswered. One hypothesis is that magnetite
HII and Shield AI Partner on Autonomy for ROMULUS USVs
currently under construction. Designed to exceed 25 knots and operate up to 2,500 nautical miles, ROMULUS 190 will carry four 40-foot ISO containers and feature both Odyssey and Hivemind for next-gen autonomous performance.Hivemind enables unmanned systems to perform complex missions even in GPS- and communications-denied environments. Proven in aerial operations, Hivemind is now expanding into the maritime domain through this partnership with HII, supporting rapid development and deployment of autonomous capabilities across domains.Under this partnership, Hivemind and Odyssey will integrate into the ROMULUS
Teledyne Expands Maritime Tech Solutions Portfolio with Latest Acquisition
team to the Teledyne family. From complete autonomous underwater vehicles to products and services for large Safety of Life at Sea (SOLAS) class vessels, maritime instrumentation and software for imaging, navigation, and safety are core markets for Teledyne.“FLIR TransponderTech’s communications and navigation solutions are highly complementary and further expand FLIR Marine’s portfolio of industrial, military, and airborne technologies,” said George Bobb, President and Chief Executive Officer
Syria Signs Landing Deal for First International Submarine Cable
Syria's telecommunications ministry has signed an agreement for the landing of the first international submarine cable to the country with Barcelona-based Medusa Submarine Cable System, state-run Ikhbariya TV reported on Saturday.The submarine cable system is intended to connect 12 countries across North Africa and southern Europe, according to Medusa's website. It will also serve as a corridor connecting the Mediterranean to the Atlantic Ocean and to the Red Sea.After 14 years of civil war and decades of Western sanctions, Syria's infrastructure shortfalls include poor internet connectivity
Deeply Innovative: Drivers in Subsea Defense
The undersea domain has never been more strategically important. From the proliferation of submarines and underwater vehicles, to the protection of subsea energy and communications infrastructure, maritime security now extends well beneath the ocean surface. As a result, defense agencies worldwide are investing heavily in underwater energy, navigation, sensing, autonomy, and communication systems to maintain domain awareness and respond to emerging threats. The companies featured in this year’s MTR100 are leaders in these areas, with innovations shaping a new era of persistent, distributed
Propane’s Economic Edge for Ports During Trade Uncertainty
demand is high and in regions with higher risk of natural disasters. According to a recent report from the Department of Energy, blackouts in the U.S. could increase by 100 times by 2030 if nationwide electrical infrastructure isn’t expanded and upgraded. For ports, grid outages can disrupt communications, IT systems, and other essential services, in addition to preventing electric terminal tractors and forklifts from recharging.Propane provides ports with an off-grid solution that reduces dependency on the grid. With onsite propane storage and backup propane-powered generators, microgrids, and
Marine Heatwaves Impact Food Webs
New research shows that marine heatwaves can reshape ocean food webs, which in turn can slow the transport of carbon to the deep sea and hamper the ocean’s ability to buffer against climate change.The study, published in the scientific journal Nature Communications today, was conducted by an interdisciplinary team of researchers from MBARI, the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, the Hakai Institute, Xiamen University, the University of British Columbia, the University of Southern Denmark, and Fisheries and Oceans Canada.To explore the impacts of
Crew Connectivity Evolves from Luxury to Lifeline
an either/or choice between LEO, VSAT, LTE, or FleetBroadband,” Griffin noted. “We bond all of those networks together into a single pipeline, delivering higher throughput and a more reliable connection.”Nexus Wave also scales with evolving technology. As new satellite services and communications options come online later this decade, they can be added seamlessly into the system. And with expanded bandwidth comes added risk—so Inmarsat has built cybersecurity directly into the offering to ensure secure, end-to-end connections.Tangible ROI for ShipownersThe payoff is already visible
