Context
Garden Reach Shipbuilders and Engineers (GRSE) launched 'Sagar Manthan', an indigenous ocean research vessel built for the National Centre for Polar and Ocean Research (NCPOR). This ₹840-crore vessel, expected to be operational by early 2028, is a crucial component of India's Deep Ocean Mission, designed to significantly enhance the nation's capabilities in deep-sea exploration, oceanographic research, and resource mapping in the Indian Ocean region and the Southern Ocean.
UPSC Perspectives
Science & Technology
The launch of 'Sagar Manthan' represents a significant leap in India's indigenous technological capabilities for ocean exploration, aligning with the goals of the . The vessel is equipped with advanced scientific systems, including sub-bottom profilers and seismic equipment, enabling high-resolution mapping of the ocean floor and geological formations. Crucially, it is designed to launch and recover autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) developed by the (NIOT). This capability is essential for conducting deep-sea surveys and sampling at extreme depths (up to 6 km), where human presence is impossible. The integration of advanced Doppler weather radar further enhances its utility for atmospheric observations, contributing to more accurate weather forecasting and climate modeling. For UPSC Prelims, questions could focus on the specific capabilities of 'Sagar Manthan' and the agencies involved (GRSE, NCPOR, NIOT). Mains questions could ask for an analysis of how indigenous research vessels reduce dependence on foreign technology and bolster India's strategic autonomy in scientific research.
Economic
This development is deeply tied to India's Blue Economy vision, which seeks to sustainably harness ocean resources for economic growth. 'Sagar Manthan' will play a critical role in exploring marine mineral resources, particularly (PMN) and polymetallic sulphides in the Indian Ocean region. PMNs, often found in the deep ocean, are rich in economically valuable metals like manganese, nickel, cobalt, and copper, which are essential for manufacturing batteries, electronics, and renewable energy technologies. By enabling the mapping and assessment of these resources, the vessel supports India's strategic efforts to secure critical minerals, reducing reliance on imports and strengthening the domestic manufacturing sector. Furthermore, the research conducted by this vessel will generate valuable data supporting sectors like shipping, energy, and marine logistics. From an examination perspective, understanding the economic significance of deep-sea mining, the environmental safeguards required, and the role of the (ISA) in regulating deep-seabed activities in areas beyond national jurisdiction is crucial.
Geographical
The operational range of 'Sagar Manthan' encompasses the equatorial Indian Ocean, the Bay of Bengal, and the Southern Ocean, including the waters around Antarctica. This expanded geographical reach is vital for advancing India's understanding of complex oceanographic processes. The vessel's ability to conduct Conductivity, Temperature, and Depth (CTD) profiling will provide essential data on ocean circulation patterns, which significantly influence regional climate systems, including the Indian Monsoon. The Southern Ocean plays a critical role in global climate regulation by absorbing heat and carbon dioxide; therefore, research in this region is essential for understanding the impacts of climate change. The vessel's capacity to operate in severe sea states ensures continuous data collection in challenging environments. UPSC aspirants should connect the capabilities of this vessel to the study of ocean currents, temperature distribution, and the broader implications of oceanographic research on climate modeling and disaster preparedness.
