The United Nations declared 2021-2030 as the UN Decade of Ocean Science for Sustainable Development. The global ocean system covers 71 per cent of the planet. Yet, it is the most unexplored and least understood component of our planet and the climate system. Ocean exploration has a long history going as far back as 5000 BC when coastal communities turned to the waters for food and later to ocean exploration around 600 BC to the colonial exploration in the 14th and 15th centuries which has continued since the 19th century in the form of scientific exploration. Regardless of this long history of exploration, as of June 2024, only about 26 per cent of the seafloor has been mapped. The impact of the ocean on climate and civilization is still an ongoing topic of research, as we understand only five per cent of this vast frontier. Recently, there has been a push towards deep sea exploration and mining to explore the deeper chasms of the oceans. India announced its idea of the Deep Ocean Mission in 2023 aimed at harnessing the resources of the deep ocean with the country’s economic zones.
