Machine Learning Application In Underwater Channel Modelling.
The research discusses the importance of underwater acoustics in understanding sound propagation in water and its various…
Inland Waterways Aids To Navigation Using Sediment Prediction.
This research note assesses the potential of Inland water transportation in India and various advantages associated with it. It highlights the ‘sediment levels predictions’ as a promising technique to make our water more navigable. It suggests…
Design And Development Of Autonomous Underwater Vehicles (AUVs) For Underwater Ambient Noise Validation.
India and many third world countries depend on rainfall for their domestic and other freshwater requirements. The non-monsoon months that constitute around 65% of the period annually, is supported by the water stored in the reservoirs. However, due to the process of water flow and…
Calculation of Sound Transmission Loss in Ocean Using Different Wave Equation Models
Underwater acoustics is the study of the propagation of sound in water and the interaction of the acoustic (sound) waves with the water, its contents, and its boundaries. While sound moves at a much faster speed…
Acoustic Method of Dark Ship Detection In the Indian Ocean Region Using Low Frequency Spatio-temporal Noise Map (software)
This research note highlights the challenges of detecting and tracking “dark ships” involved in illegal activities within a nation’s Exclusive Economic Zone (EEZ), particularly in the Indian Ocean region. These ships often turn off their Automatic Identification System…
A Computationally Efficient Model For Determining Sound Speed In Shallow Tropical Freshwater Systems, With Field Validation.
India and many third world countries depend on rainfall for their domestic and other freshwater requirements. The non-monsoon months that constitute around 65% of the period annually, is supported by the water stored in the reservoirs. However, due to the process of water flow and accumulation…
3D Shipping Radiated Noise Mapping.
The project undertaken is a step forward in the direction to explore and build a better acoustic capacity in the Indian Ocean Region (IOR) required for the enhanced Underwater Domain Awareness (UDA). It says that a 3D sound map…
3D Ambient Noise Mapping Using Wittekind Model In Indian Ocean.
The article discusses the issue of ocean ambient noise and its impact on marine mammals, maritime security, strategic missions, and the health of divers. Commercial shipping is identified as a major source of noise in the sea, with…
Analysis of Underwater Radiated Noise Based On Vessel Hull Vibrations.
This article discusses the issue of ocean pollution, specifically the impact of increased ambient noise on marine life, caused by anthropogenic (human-induced) sources such as maritime shipping and seismic exploration by the oil/gas industry…
