Researchers Link Antarctic Ice Loss to Subsurface “Storms”
10 kilometers across, tiny in the context of the vast ocean and huge slabs of floating ice in Antarctica.“In the same way hurricanes and other large storms threaten vulnerable coastal regions around the world, submesoscale features in the open ocean propagate toward ice shelves to cause substantial damage,” said lead author Mattia Poinelli, a UC Irvine postdoctoral scholar in Earth system science and NASA JPL research affiliate. “Submesoscales cause warm water to intrude into cavities beneath the ice, melting them from below. The processes are ubiquitous year-round in the Amundsen Sea
Analytics System for Subsea Power Cable Maintenance Launched
, meteorological and oceanographic inputs, and power production data, Scattersphere builds a complete, real-world picture of each cable’s condition and performance. The system’s automated analytics then identify emerging risk signatures, enabling operators to act months or even years before damage occurs.Applicable for array cables, export cables and even interconnectors, Scattersphere addresses one of the sector’s most persistent challenges – the high cost and frequency of cable failure. Across the UK offshore wind market alone, unplanned cable failure has cost more than £
One Fish, Two Fish
camera-based decision support for fish farming of salmonides. Their system leverages AI and machine learning to deliver real-time data for fish farmers while reducing the amount of physical handling of the fish. They provide data on fish weight and growth, welfare indicators such as skin health and fin damage, and data on the behavior of the fish in the pen.Aquabyte's camera-based monitoring of welfare and behavior plays a crucial role in submerged production, where it is otherwise challenging to observe the fish. A key component of Aquabyte's behavior module includes monitoring the fish's
Indeximate Demos Cable Health Monitoring Tech on RWE Subsea Cables
cloud portal, the Scattersphere, where automated analytics extracted several long-term risk profiles for the cable including abrasion, strain, fatigue integrity and vibration.Automated analysis of the data identified signatures related to cable movement, abrasion and vibration, as well as fatigue and damage. Analysed alongside co-registered wave and wind data, the long-term data record allows Indeximate to observe how the cables behaved in certain conditions, such as directional weather and specific wave heights and identify where issues may emerge. These insights have the potential to identify points
MacArtney, Teledyne ODI Expand Connector Service Across Europe
These include assemblies with molded solutions tailored for test connectors and short-life subsea applications. Test connectors play a vital role in verifying system integrity before deployment, enabling operators to simulate real-world conditions and ensure reliable performance without risking permanent damage to equipment. The MacArtney options with molded solutions will complement the Teledyne ODI product offering, adding flexibility to meet unique operational needs.The initiative supports MacArtney’s broader connectivity portfolio, which includes SubConn, OptoLink and TrustLink connectors.

PML Study Finds Tire Microplastics Impact Estuarine Animals
from both natural and synthetic rubber and are a type of microplastic. But plastic isn’t the only problem with this pollutant; tires contain a cocktail of chemicals, trace metals, volatile organics and antioxidants, designed to increase tire longevity, reduce road resistance, and protect from UV damage. These tire particles – smaller than 5 mm – are released onto highways, verges and the air, with rainfall and runoff washing them into rivers and estuaries, where they can settle into sediments or remain suspended in the water. Studies have discovered high abundances of tire particles
Finland Court Rules It Lacks Authority in Baltic Sea Cable Breach Trial
critical underwater infrastructure, but is complicated by provisions of international maritime law and the difficulty of proving criminal intent. The three crew members denied the charges."The District Court has today issued a judgment dismissing the charge in the case... along with the claims for damages arising from the charge, as it was not possible to apply Finnish criminal law to the case," the court said in a statement.Under the United Nations Convention on the Law of the Sea, the power to prosecute any crime rests with the ship's flag state or the defendants' native countries
NOAA and Partners Deploy C-Star USVs to Collect Hurricane Data
;NOAA has been expanding the use of uncrewed aircraft and marine systems to collect and use high-accuracy and time-sensitive data across its mission. A diverse array of uncrewed systems are already used in seabed mapping, marine mammal and fishery stock assessments, emergency response, including tornado damage assessments, and at-sea observations that improve forecasting of extreme events, such as hurricanes, harmful algal blooms and hypoxia. How the C-Star worksThe C-Star was developed by U.K-based company Oshen, which builds constellations of hand-deployable robots for ocean data collection. C-Stars
Azerbaijan Officials Express Concern Over Shallowing of the Caspian Sea
Rapid falls in the level of the Caspian Sea are affecting ports and oil shipments and threatening to inflict catastrophic damage on sturgeon and seal populations, according to Azerbaijani officials.The Caspian, the world's largest salt lake, holds significant offshore oil reserves and is bordered by five countries that are all major producers of oil or gas or both: Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan.Azerbaijan's Deputy Ecology Minister Rauf Hajiyev told Reuters that the sea had been getting shallower for decades, but figures showed that the trend was accelerating.Its level
