Matters relating to survey to map, locate and assess living and non-living marine resources fall primarily within the purview of the Ministry of Earth Sciences (MoES). MoES is responsible for ocean science and technology, including research vessels, ocean surveys, and mapping of marine resources.
The Ministry of Earth Sciences is the nodal ministry in India for all matters related to the Earth system, including oceans. Its mandate includes undertaking ocean surveys, mapping, and assessment of both living and non-living marine resources.
The National Institute of Oceanography (NIO) is a research laboratory under the Council of Scientific & Industrial Research (CSIR), which is under the Ministry of Science and Technology, not MoES. While NIO conducts relevant research, the overall governmental responsibility and coordination lie with MoES. The Department of Fisheries (under the Ministry of Fisheries, Animal Husbandry and Dairying) deals with fisheries management and regulation of living resources, but not the broad survey and assessment mandate covering non-living resources and mapping. The Coast Guard is primarily concerned with maritime safety and security.
