A way ahead view on URN Management
Effective management of underwater radiated noise (URN) is crucial for both
environmental conservation and operational efficiency in maritime activities. Acoustic stealth
technologies are pivotal in minimizing detection risks for submarines and surface vessels,
thereby enhancing survivability and mission success. However, challenges such as
inconsistent global regulations, inadequate data on noise impacts, and technological
limitations in monitoring and mitigation persist.
URN management in freshwater systems Emphasis on Ganges River dolphin
Underwater radiated noise in freshwater systems is a critical environmental issue
affecting aquatic habitats globally. This research note examines the primary sources of
underwater noise and their socio-economic implications, emphasizing spatial planning
challenges. It focuses on river dolphins, notably the Ganga River dolphin (Platanista
gangetica), highlighting the adverse effects of noise pollution on this endangered species.
Holistic Approach to Optimize Indian Dredging Practices
This research note explores the challenges and methodologies of dredging in India’s tropical coastal regions. Influenced by seasonal monsoon winds and significant sediment contributions from the Himalayas, these areas require careful management. Dredging is crucial for maintaining navigational channels and infrastructure, but it poses distinct environmental challenges.
Statistical Interface of Climate Change Impact in the Indian Ocean Region
In a report by FAO (2017) it is indicated that globally there would be a decline in fish production value of 21% by 2050 resulting in annual losses of USD 311 million for the fishing sector due to increased ocean water temperature.
Water Quality in India: A Contemporary Perspective
Water Quality Management System (WQMS) focuses on protecting and improving water quality across various resources like groundwater, ocean water, and freshwater. In India, rapid urbanization, agricultural runoff, and inadequate wastewater treatment pose significant challenges to maintaining water quality
Sediment Transport Study of Indian Tropical Rivers
This research highlights the importance of creating an Underwater Domain Awareness (UDA) Framework specifically for managing sedimentation. Sediment management is a complex challenge that requires collaboration among various stakeholders to avoid fragmented approaches and ensure effective policy development.
Study Of Seaweeds Sub Species And Their Applications.
Seaweeds are macroalgae found along coastlines worldwide, classified into brown, red, and green algae. They serve as a foundation of aquatic food chains and are rich in nutrients like proteins, lipids, and vitamins. Seaweeds offer…
Tropical Waters And Unique Characteristics: Physical Characteristics Of The Indian Ocean
The Indian Ocean has traditionally functioned as a crucial hub for marine commerce, enabling the linkage between the East and West via ancient trade routes such as the Silk Road and Spice Route. It continues to serve as a crucial international…
Tropical Waters And Unique Characteristics: Indian Freshwater Systems
India’s riverine conditions are shaped by the many rivers and lakes that run through the country’s colossal landscape and affect its hydrological dynamics. Himalayan and Peninsular rivers are the two main groups of rivers based on their origin. Himalayan rivers, like the Ganga, Yamuna, and the Indus, are primarily perennial. They get their water from snow and rain in the…
Tropical Waters And Unique Characteristics: Anthropogenic Perspective Of The Indian Ocean
Today, the Indian Ocean (IO) is important because it is a crucial route for world trade, especially in energy. Its extensive and heavily populated littoral includes some of the world’s fastest-growing areas. Around 800 CE, ocean shipping for foreign trade began. This made it easier for people in Africa, India, and China…
