Oceanography — Predicted 2026
AI-Predicted Question Angles for UPSC 2026
Deep-Sea Mining: Opportunities, Challenges, and India's Stance
HighWith India's Deep Ocean Mission progressing and the International Seabed Authority (ISA) actively debating regulations for deep-sea mining, this topic is ripe for both Prelims and Mains. Questions could focus on the types of resources (polymetallic nodules, sulphides), the technology involved, the potential economic benefits for resource-rich nations, and critically, the severe environmental concerns (habitat destruction, biodiversity loss, ecosystem disruption). India's position as a 'pioneer investor' and its push for a share in deep-sea resources, balanced with environmental safeguards, makes it a highly relevant and complex issue for UPSC.
Ocean Thermal Energy Conversion (OTEC) and India's Renewable Energy Goals
Medium to HighAs India diversifies its energy basket and pursues ambitious renewable energy targets, OTEC, which harnesses the temperature difference between surface and deep ocean waters, presents a unique opportunity. The Deep Ocean Mission includes OTEC development. Questions could explore the principle of OTEC, its advantages (baseload power, freshwater byproduct), disadvantages (high capital cost, efficiency, environmental impacts), and its potential role in India's energy security strategy, especially for island territories. This links directly to Science & Technology, Environment, and Economic Geography.
Impact of Climate Change on Marine Biodiversity and Food Security in the Indian Ocean
HighThe Indian Ocean is one of the fastest-warming oceans, and its vulnerability to climate change is a significant concern. Questions could delve into the impacts of rising sea surface temperatures (coral bleaching, marine heatwaves), ocean acidification, and altered current patterns on marine biodiversity, fish stock distribution, and ultimately, the food security of coastal communities in India and neighboring countries. This angle demands an integrated understanding of oceanography, environmental science, and socio-economic impacts, making it a strong candidate for Mains questions, particularly in GS Paper III.
