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…
Collision Avoidance In Inland Waterways By Using AIS Data
Collisions in Inland waterways represent the biggest threat to inland water transportation. Its occurrence is very infrequent but has terrible consequences that make its avoidance a very imperative factor. This work aims to identify all the techniques that have been developed so far…
Automating Static AIS Data
This research note talks about the Automatic Identification System (AIS), which was developed to track vessel movements and has proven quite effective in dealing with a wide range of problems ranging from fleet monitoring and collision to detecting…
APY Analysis For Shrimp Farming
India has a long coastline which offers it with immense opportunities to harvest aqua resources. In India aquaculture has grown in the last few decades at a high growth rate. Before the 1970s fishermen used to harvest only marine fishes…
Sediment Management For UDA* Framework.
This research note highlights the importance of developing a UDA Framework for Sedimentation Management. It suggests that Sedimentation Management is a large-scale multilevel problem and requires cooperation from different stakeholders to avoid fragmented approach…
Sediment Management For The Brahmaputra River.
This research note highlights the existing issues related to the sedimentation problem in one of the largest rivers in India, i.e. the Brahmaputra River. It draws attention to various issues related to the river and how the gaps in the existing policies…
Mapping Snapping Shrimp Noise In The Indian Ocean Region.
The article discusses the use of snapping shrimp noise in the Indian Ocean Region (IOR) to improve underwater acoustic systems. Snapping shrimp produce loud snaps that can disrupt underwater communication. The characteristics of snapping shrimp, analyzes the…
