World Ocean Assessment Report Highlights Changing Chemistry
biological studies.For now, the acquisition of real-time or near-real-time data is skewed towards physical variables rather than biological variables, with biochemical variables falling somewhere in between. This imbalance is due to the complexity of the biological components of marine ecosystems, the diverse nature of their variables (e.g. taxonomic, ecological and physiological), the lower number of sensors developed for biological variables and the energy consumption required for image acquisition systems and active acoustic sensors.Long-term monitoring and observation systems are needed to understand
Ocean-Bottom Seismometers Play Crucial Role in Offshore Sensing
land-based sensors alone.But positioning them and, crucially, recovering them to download their data, then getting them ready for the next deployment, isn’t simple, especially when locations range from ice-covered Arctic waters to 4,700 m deep abyssal plain. And because the NSFI team relies on diverse “vessels of opportunity," from small fishing boats to ice-rated trawlers and large coastguard ships, and operates with a very small field staff, their choice of underwater positioning also has to be flexible.Deployment in January in New Zealand.

Millions of Coral Larvae Released at Nyinggulu
spawning and larval development times for Nyinggulu, including locations that were previously unrecorded.“We’ve also successfully demonstrated that large-scale, reef-based mass larval production and release of coral larvae is a feasible option to support regeneration on Nyinggulu’s diverse reef systems.”Given coral takes years to grow, the results of the trial won’t be known for a couple of years. Project Director for the Nyinggulu trial Dr Jenny Shaw, says there is no doubt this year’s spawning process has been given an advantage, and that trial has created a new
UK Hydrographic Office Launches Digital Format for ADMIRALTY Sailing Directions
of indicative routes within the geo-display enables more dynamic passage planning, simplifying access to key routing information. Intuitive by design ADSD has been developed in close consultation with navigating officers from around the world, including testing across a diverse range of vessel types and navigational scenarios. In a survey of more than 50 mariners who used ADSD:88% of users said ADSD was intuitive and easy to use 91% of users agreed ADSD’s geo-display made sailing directions easier to understand 88% of users said ADSD saved
U.S. Navy Selects HII USV to Advance to At-Sea Testing
;HII’s Odyssey Autonomous Control Solutions (ACS) is currently deployed on REMUS unmanned underwater vehicles (UUVs) and ROMULUS USV platforms in 30 countries, transforming vehicles into intelligent robotic systems. Through flexible vehicle-, module-, and algorithm-level implementations across diverse platforms, sensors, payloads, and mission profiles, Odyssey Advanced Autonomy Solutions deliver multi-vehicle collaborative autonomy, sensor fusion, and advanced perception capabilities.The ROMULUS family of Unmanned Surface Vessels is designed to meet the current and emerging requirements of the
International Youth Ocean Leadership and Advocacy Program Arrives in Poland
for young scientists, students and early-career researchers.Participants will share research, ideas and perspectives across humanities and social sciences, as well as natural and physical sciences. The program also includes a dedicated session on inclusiveness in science, highlighting the importance of diverse voices and accessible research environments.Selected contributions will be published in registered conference proceedings with ISBN and recognized with awards for outstanding work
SYOS Introduces SU10 UUV
uncrewed underwater vehicle (UUV) to extend and strengthen its multi-domain autonomous uncrewed portfolio across air, land, sea to subsurface.The SU10 is designed for mine countermeasures (MCM), critical subsea infrastructure protection and persistent surveillance and maritime security. It can support diverse missions such as search, identification and route clearance, infrastructure inspection and intervention.Combined with other SYOS uncrewed vehicles, the SU10 can deliver integrated and scalable multi-domain operations in contested environments, executing complex missions.SYOS CEO and founder, Sam
Seiche Leads Pilot Study to Assess Piling Noise Offshore
Evidence and Change program is an ambitious strategic research and data-led program. Its aim is to facilitate the sustainable and coordinated expansion of offshore wind to help meet the UK's commitments to low carbon energy transition whilst supporting clean, healthy, productive and biologically diverse seas
eXXpedition All-Women Sailing Mission Sets Off to Map Global Ocean Plastic
After her trip, Dr Jambeck went on to publish groundbreaking research that became one of the most cited papers ever on plastic pollution. Crucially, the research on this mission will be conducted in collaboration with scientific partners, local communities and leaders in each region. A crew as diverse as the solutions requiredThis mission, like all of eXXpedition’s voyages, will be crewed by multidisciplinary women from across the globe, most of whom have no sailing experience. The first crew members include an engineer from Bulgaria, an entrepreneur from Austria, a materials innovator
