Autonomous Maritime Systems and Strategic Undersea Infrastructure: China’s Emerging Ocean Technologies
This research note examines China's development of autonomous maritime systems and strategic undersea infrastructure, exploring how these capabilities form a smart ocean architecture that enhances surveillance, underwater domain awareness (UDA), and maritime influence across the Indo-Pacific, with particular significance for the Indian Ocean Region (IOR).
Antifouling Techniques: History and Evolution of Marine Fouling Control
This review examines the evolution and current state of antifouling technology in marine engineering, tracing its development from early empirical methods to modern environmentally sustainable solutions. It highlights the impact of the 2008 IMO ban on tributyltin (TBT), the emergence of advanced coating technologies, and the growing shift toward non-toxic antifouling systems that improve vessel efficiency while meeting environmental regulations.
Fisheries and Socio-Economic Impact Assessment: CPUE Improvement, Seasonal Harvest Optimization, and Fisher-Level Benefits
The Enhanced Fishing Suitability Index (FSI) delivers measurable socio-economic benefits by improving fisheries efficiency, reducing operational risks, and supporting sustainable resource management. With projected CPUE gains of 15–23% and annual economic benefits exceeding INR 300 crore for Maharashtra alone, the framework demonstrates how advanced ocean intelligence can strengthen fisher livelihoods, improve food security, and accelerate India's Blue Economy objectives.
Scientific Foundation for Multi-Parameter Fisheries: Intelligence Oceanographic Basis, Single-Parameter Limitations, and the Case for Integrated Assessment
This note addresses three foundational questions: (1) What are the key oceanographic processes governing fish habitat quality in the tropical Arabian Sea? (2) Why do single parameter approaches fail to capture the full complexity of these processes? (3) What scientific basis supports the development of a multi-parameter composite suitability in dex?
Technical Architecture and Modeling Framework for Multi-Parameter FSI: Data Pipeline, Normalization, Correlation Insights, and Habitat Compression Modelling
This research note details the technical architecture underpinning the Enhanced Fishing Suitability Index (FSI) for the Ratnagiri coastal zone. This note focuses on the computational pipeline: data ingestion from NetCDF ocean model outputs, depth integration and extraction strategies, normalisation schemes, weighting rationale, and the spatial interpolation methodology developed for operational deployment on H3 hexagonal grids.
Policy and Strategic Perspective for Multi-Parameter Fisheries Intelligence: INCOIS Gap Analysis, Climate-OMZ Imperatives, and the Case for Advisory System Upgrade
The transition from conventional dual-parameter fisheries advisories to a multi-parameter intelligence framework is a strategic necessity for India. Driven by climate change, ocean deoxygenation, and evolving fisheries dynamics, the proposed approach offers improved decision-making, enhanced sustainability, and greater economic resilience. The report outlines a practical policy roadmap for modernizing fisheries advisories while strengthening India's leadership in the Blue Economy and Underwater Domain Awareness domains.
APY Analysis For Shrimp Farming
Shrimp farming in India plays a vital role in the blue economy, contributing significantly to export growth, coastal development, and livelihood generation. Despite challenges like low efficiency and environmental issues, APY analysis and modern technologies offer solutions for sustainable growth and productivity enhancement.
