World Ocean Assessment Report Highlights Changing Chemistry
, which are now known to affect more than 4,000 marine species.Large gaps persist in ocean knowledge, with only 27.3% of the seafloor mapped as of 2025, leaving deep sea ecosystems, biological processes, and cumulative impacts poorly understood.However, the Assessment notes the rapid development of technologies and methodologies for ocean observation. Together with advances in modelling, they are greatly increasing the scientific understanding of the ocean and the development of management tools.The use and development of automated or semi-automated ocean observation platforms, such as Argo floats (which
Ocean Waves Contribute to the Seasonal Melting of Antarctic Sea Ice
cause further sea-ice loss.“This underlines a need for modelling research, and observations of these previously neglected wave processes and feedbacks, to fully understand and quantify their overall contribution to seasonal sea-ice melting around Antarctica and in the Arctic.“Sophisticated technologies such as autonomous camera systems on icebreakers are crucial to assisting with the new observations.“Ultimately, we should encourage and enable the inclusion of wave-melting processes and feedbacks in next-generation climate and Earth-system models.“This would help improve understanding

FAU Receives Grant to Transform Underwater Robotic Communication
autonomous underwater vehicles, seabed sensors, and maritime operators share information more quickly, reliably, and securely. The technology addresses one of the greatest challenges facing underwater operations today: maintaining real-time communication in an environment where conventional wireless technologies – such as radio waves and GPS – do not function.“Today’s underwater communication systems typically force operators to choose between range and speed,” said George Sklivanitis, Ph.D., principal investigator, associate director of the CA-AI, the Charles E. Schmidt
EU Funds OceanEye Initiative
Commission has expanded the EU's role in ocean observation by adopting OceanEye.This initiative aims to position the EU as the world's leading provider of ocean intelligence by contributing to 35% of the global ocean observing system by 2035 and securing 35% of the market for ocean observation technologies.The ocean covers 70% of the Earth's surface, yet only 5% has been explored. Ocean observation is critical for ocean protection and restoration, climate forecasting, blue economy activities such as fisheries and aquaculture, offshore energy, and shipping, as well as maritime security and defense
Scaling the Uncrewed Fleet: From Single Vessels to System-Level Operations
Oceanology International has long been a showcase for emerging marine technologies, but in recent years it has also become a marker of something more fundamental: how quickly those technologies are maturing.This year, one trend stood out. The conversation is no longer centered on whether uncrewed surface vessels (USVs) can demonstrably work, but rather how they can be scaled effectively. From small pilot platforms to larger, more capable vessels, the industry is entering a phase where the technology is proven. Now, it is all about the integration, coordination, and operational models, from individual
Ocean Visions Launches Seaweed Decarbonization Roadmap
conventional products emissions-intensive. While seaweed aquaculture is already a major global industry, produced primarily for food and hydrocolloids, scaling seaweed-based products for decarbonization such as biofuels and bio-stimulants will require significant expansion, along with improved technologies and processes to cultivate, harvest, and process biomass efficiently. Ocean Visions’ new road map highlights the scientific, economic, technological, and policy conditions needed for seaweed-based products to contribute meaningfully to global decarbonization. It focuses on five key
Seaturns Deploys Full-Scale Wave Energy Demonstrator in Atlantic
the demonstrator.According to Seaturns, the collaboration reflects growing interest in wave energy as a scalable renewable technology and could help support a planned fundraising round in early 2027.Ireland has one of Europe's largest wave energy resources, and ESB has been monitoring wave energy technologies as part of its Net Zero by 2040 strategy.Seaturns also unveiled plans to raise funds in early 2027 to support the progression of its technology toward commercialization, industrialization and future project development
Aker BP and Viridien Deepen North Sea Seismic Collaboration
Viridien's seismic imaging technology and geoscience expertise. The companies also plan to expand multi-client OBN seismic coverage to support large-scale exploration activities on the Norwegian Continental Shelf.The collaboration will focus on advancing seismic acquisition, imaging and processing technologies to improve subsurface data quality and support exploration and field development activities.“Aker BP sees ocean bottom node seismic as a key enabler for improved imaging and higher-quality subsurface data, both in exploration and field development. Together with Viridien we will further
