BackgroundCore Concept

Background

India's engagement with the deep ocean has grown significantly in recent years. The Deep Ocean Mission, launched under the Ministry of Earth Sciences (MoES), is the country's flagship programme for deep-sea exploration. It encompasses several sub-projects. Samudrayaan is one such project, under which the Matsya-6000 submersible has been designed to carry three people to depths of up to 6,000 metres for scientific exploration. The mission's institutional home under MoES is important: it is not under the Ministry of Ports, Shipping and Waterways, a distinction UPSC has directly tested.

The Centre for Marine Living Resources and Ecology (CMLRE), based in Kochi, is a key MoES institution. Its mandate covers marine biodiversity research, benthic ecology, and living resource assessment in the Indian Ocean. CMLRE conducts surveys of the deep seabed, particularly in India's licensed exploration zones in the Central Indian Ocean Basin. This work requires robust taxonomic expertise, the scientific ability to identify, classify, and document marine organisms, which is precisely the gap this training programme addresses.

The Indian Ocean Rim Association (IORA), formerly known as IOR-ARC, is a regional cooperation forum. It was not established specifically to address piracy or oil spills, and its mandate extends well beyond maritime security to trade, investment, fisheries, science, and cultural cooperation. IORA's involvement in this training reflects its broader role as a platform for scientific and developmental collaboration among Indian Ocean states.

The Topic Explained

The International Seabed Authority (ISA) is an autonomous international body established under the UN Convention on the Law of the Sea (UNCLOS). It regulates all mineral-related activities in the international seabed area, the area beyond national jurisdiction, known as the "common heritage of mankind." Before any mining or exploration can proceed, ISA requires contractors to conduct environmental baseline studies. These studies depend on accurate biodiversity assessments of the deep seabed, which in turn require trained taxonomists.

Taxonomy, the science of identifying and classifying organisms, is a foundational but increasingly scarce skill globally. Deep-sea macrofauna taxonomy is especially specialised. Macrofauna refers to organisms retained on a 0.3 mm sieve from seabed sediment samples. …
