AIS Data Profiling For Error Analysis In Indian Ocean Region (IOR)

The Project discusses the importance of the Automatic Identification System (AIS) in enhancing safety and efficiency in maritime navigation. It highlights the potential negative impact of fast mandatory implementation of AIS without adequate research on its use, citing examples of AIS-assisted collisions. The need for specific dominant…

Vessel Trajectory Reconstruction Of Missing AIS Data Values Machine Learning.

The report discusses the importance of Automatic Identification System (AIS) data in tracking vessel trajectories and its applications in various fields such as mapping shipping density, characterizing marine traffic patterns, anomalous behavior detection of ships, collision risk analysis, investigation of maritime accidents, and maritime route generation for…

Shipping Radiated Noise Estimation Using AI.

This research note highlights commercial ships are the major source of underwater radiated noise, which is generated because of interaction between hull, water and propeller cavitation that lies in the low-frequency range. It states that various…

Radiated Noise Generation

This paper states that the standard modes of signal transmission underwater are acoustic waves and a large majority of marine life uses sound waves for regular movement. Therefore, the classification and analysis of sources of underwater noise becomes imperative. The study classifies the noise in context of ships into following…

Mapping Snapping Shrimp Noise In The Indian Ocean Region: Impact On Sonar.

The Project discusses the impact of snapping shrimp on sonar systems in the Indian Ocean Region (IOR). Snapping shrimp are a major source of high-frequency noise in the ocean and their activities and habitation in shallow waters…

Low Frequency Shipping Ambient Noise Mapping For Passive Sonar Simulator.

The research note talks about an ingenious Passive Sonar Simulator (PSS) that the authors aim to develop using real time data inputs will be a critical tool for fulfilling our audacious objectives. The research note suggests that the complex tropical littoral waters of the Indian Ocean Region provide us with challenges to…

AUV Design And Development To Validate Low Ambient Frquency Noise.

Autonomous Underwater Vehicles (AUVs) are self-propelled, unmanned underwater vehicles that can perform tasks with little or no human supervision. They are used for ocean-based research, such as mapping the seafloor, studying ocean properties, and measuring ambient noise…

AUV Design and Development for Deep Sea Mining (Polymetallic Nodules)

This Paper will provide information about underwater robot technology and its application for the mining process in the deep sea ocean.This article first discusses why polymetric…

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 are causing a problem in resolving…
