Does new digital infrastructure promote the low-carbon transformation of fisheries: evidence from carbon emissions across Chinese provinces
New digital infrastructure (NDI) presents a critical pathway toward achieving China’s “dual carbon” goals within the fisheries sector. A recent study, utilizing longitudinal panel data across 30 Chinese provinces (2004-2024), demonstrates a statistically significant reduction in fishery carbon emissions linked to NDI development. Findings reveal that NDI fosters technological progress, optimizes industrial structure, and promotes cleaner energy adoption, with spatial spillover effects indicating broader regional benefits. For further exploration of maritime innovation, see our coverage of China’s deployment of a bamboo-built offshore solar platform.

U.S Navy Retrains Deep-Sea AI Sonar In Under 5 Minutes At The World’s Largest Naval Exercise
Lockheed Martin reports a significant advancement in naval technology: the U.S. Navy successfully retrained deep-sea AI sonar in under five minutes during the world’s largest naval exercise. This innovative system empowers naval helicopter operators to monitor twice the number of sonar feeds compared to legacy systems, representing a substantial increase in operational efficiency. The technology underscores a commitment to rapid adaptation and integrated data ecosystems within naval operations.

Data-driven modelling of coastal water quality dynamics
Long-term coastal monitoring offers a unique opportunity to assess water quality predictability, yet existing machine learning studies often lack comprehensive scope. Our analysis of 37 years of data from 94 stations across four Hong Kong Bay systems reveals significant regional variations in predictability and key predictors. Tree-based models demonstrated robust performance, particularly for temperature and salinity, while chlorophyll-a proved consistently challenging to forecast.

Machine learning predictions for microbial eukaryotic plankton: implications from unevenly structured data
Machine learning offers a promising avenue for predicting eukaryotic microbial plankton diversity from environmental data; however, model generalizability remains a critical challenge. This study utilized XGBoost to model 18S rRNA gene Shannon Diversity Index (SDI) across the Mediterranean Sea, revealing significant limitations in transferability due to unevenly structured data. Performance declined substantially when tested against independent datasets, highlighting the need for spatially explicit evaluation and standardized protocols. Understanding these constraints is essential for robust ocean intelligence.

Explicit wave height prediction model and regularity analysis for floating breakwaters based on deep symbolic regression
Accurate wave height prediction is critical for coastal engineering and aquaculture safety. This study validates a novel approach utilizing Physical Symbolic Optimization (PhySO) to model wave attenuation behind floating breakwaters. Employing real-world data from Fujian Province, the research developed explicit, interpretable formulas for significant (Hs) and maximum (Hmax) wave height prediction. Notably, the Hmax model achieves accuracy comparable to complex machine learning methods, while incident wave height emerges as the dominant controlling factor, demonstrating PhySO’s value in balancing precision and practical application.

Machine learning, eDNA and citizen science in monitoring and assessing biodiversity and invasive alien species at sea
Emerging technologies are revolutionizing marine biodiversity and invasive alien species monitoring. This research, presented at a recent summer school, details the integration of machine learning, citizen science, and environmental DNA (eDNA) alongside remote sensing and drones. Machine learning, utilizing frameworks like Essential Biodiversity Variables (EBVs), enables efficient species identification and global data synthesis. Initiatives like iNaturalist exemplify the power of citizen science combined with AI validation.
