New Deep-Sea Coral Discovery in Andaman Sea: A Milestone for India’s Marine Biodiversity

However, the discovery also brings to light the vulnerabilities of deep-sea ecosystems. While deep-sea environments were once thought to be buffered from surface changes, recent studies indicate that rising sea temperatures and ocean acidification are penetrating deeper into the ocean. These changes can disrupt the calcium carbonate skeleton formation of corals, leading to habitat loss. Furthermore, the proximity to volcanic activity provides a natural laboratory to study how species adapt to extreme thermal and chemical environments, which is crucial for predicting the impacts of global warming. From a policy perspective, this finding reinforces the objectives of India’s Deep Ocean Mission and the draft Blue Economy Policy. It emphasizes the need for comprehensive mapping of the seabed and the establishment of Marine Protected Areas (MPAs) in deep-sea regions to prevent damage from potential deep-sea mining or bottom trawling. UPSC Relevance: This news is highly relevant for GS Paper I regarding changes in critical geographical features and flora/fauna, and GS Paper III concerning environmental conservation. It can be used as a case study in answers related to marine biodiversity, the impact of climate change on deep-sea ecosystems, or the strategic importance of India's maritime zones.
