Explanation: The Coastal Research Vessel (CRV) Sagar Anveshika is a significant development in Tamil Nadu's maritime research capabilities. It was launched at the Chennai Port, which is a major port in the state of Tamil Nadu, India. The vessel is specifically designed for coastal research and monitoring, which includes studying the marine environment, conducting surveys, and gathering data on coastal ecosystems.
The CRV Sagar Anveshika is equipped with advanced scientific instruments and technology to support marine research. It can be used for various purposes such as studying marine biodiversity, monitoring water quality, and conducting hydrographic surveys. The vessel is an important asset for researchers and scientists working in the field of marine science and environmental studies.
It is important to distinguish between different types of research vessels. For example, the Ocean Research Vessel (ORV) Sagar Kanya, which is another vessel used for marine research, is not the same as the CRV Sagar Anveshika. The ORV Sagar Kanya is primarily used for oceanographic research and was launched earlier than the CRV Sagar Anveshika.
Similarly, the Fisheries Oceanographic Research Vessel (FORV) Sagar Sampada is used for fisheries research and is not the recent vessel launched at the Chennai Port. Each of these vessels has a specific purpose and is designed to meet the needs of different types of marine research.
In conclusion, the CRV Sagar Anveshika is the correct answer as it is the Coastal Research Vessel that was recently launched at the Chennai Port. This vessel plays a crucial role in advancing our understanding of coastal ecosystems and supporting marine research in Tamil Nadu.
