The accompanying White Paper charts a path for sustainable growth through technology, innovation, and policy support to enhance global competitiveness. Together, they present a roadmap for making India’s shrimp sector more sustainable, inclusive, and globally dominant in the seafood market.
Precision Mapping: Harnessing Geographic Coordinates for Effective Identification of Aquaculture Ponds to Enhance Spatial Planning
This research focuses on precision mapping of aquaculture ponds using geographic coordinates to enhance marine spatial planning (MSP). It emphasizes the ecological importance of mangroves, the environmental impacts of aquaculture, and sustainable restoration strategies. The study applies coordinate conversion and georeferencing techniques for accurate pond identification and ecosystem management.
Underwater Radiated Noise (URN) Management Technological and Policy Interventions
This research focuses on managing Underwater Radiated Noise (URN) through a blend of technological innovations and policy interventions. It emphasizes acoustic capacity building, real-time monitoring, and sustainable marine spatial planning to mitigate noise impacts. The study aligns with global frameworks like IMO guidelines to protect marine ecosystems from anthropogenic noise pollution.
Review To 3D Mapping Of Low Frequency Ambient Shipping Noise.
The history of underwater sound modeling began in the 19th century with early sound speed experiments and evolved rapidly after World War I through sonar development. Over time, modeling advanced from simple 2D ray theories to complex 3D simulations integrating bathymetry, temperature, and ship noise data. Modern approaches now use tools like CFD, AI, and 3D acoustic models to achieve precise predictions of underwater noise propagation, aiding naval, environmental, and research application.
Noise & Vibration Management on-board Marine Vessels
This research explores Noise and Vibration (N&V) Management on Marine Vessels, focusing on crew comfort, machinery maintenance, and underwater radiated noise (URN) reduction. It studies how on-board vibrations impact ship performance, structural fatigue, and marine ecosystems. The paper integrates modelling, measurement, and international standards to promote safer, quieter, and more sustainable maritime operations.
Shipping Radiated Noise Estimation Techniques.
This research note aims to identify all the ‘Shipping Radiated Noise Estimation Techniques’ that have been developed so far, which enables us to derive shipping radiated noise based on Automatic Identification System (AIS) data. It highlights details on the use of AIS in conjunction with Hydrophones and thereby gives its applications. It further highlights the standalone use of AIS data and how it can be applied (its application). The research note recommends that even though the shipping noise estimation via the use of AIS data has found some important applications, there is still a lot of work that needs to be done, in terms of improvising the efficiency, speed and resolution of output obtained.
Sediment Bearing Pressure Analysis Using Sediment Classification Techniques.
This project focuses on Sediment Bearing Pressure Analysis using acoustic and model-based sediment classification techniques. It aims to determine seafloor strength, stability, and bearing capacity critical for offshore construction, exploration, and defense applications. The study integrates acoustic remote sensing, sub-bottom profiling, and Biot-Stoll modeling to estimate sediment properties efficiently and accurately.
