Why is it in the news?

• Researchers in the USA have recently made a groundbreaking discovery by mapping the largest deep-sea coral reef off the Atlantic coast of the United States, spanning an impressive 310 miles (499 kilometres) from Florida to South Carolina.
• Ranging from 200 meters to 1000 meters, the depth of the reef surpasses the reach of sunlight, creating a unique ecosystem in the ocean’s depths.

About Coral Reefs

• Coral reefs are structures formed by coral polyps held together by calcium carbonate, creating intricate underwater ecosystems.
• Often referred to as the tropical rainforests of the sea, coral reefs cover only 0.1% of the ocean’s surface but provide habitats for 25% of marine species.
• The Great Barrier Reef in Australia is known as the world’s largest tropical coral reef system.

Differences Between Deep and Shallow Water Coral Reefs:

Threats to Coral Reefs:

• Both shallow and deep-sea coral reefs face threats from climate change, including rising sea temperatures and ocean acidification.
• Oil spills and other forms of pollution pose significant risks to coral reefs, affecting their health and the marine life they support.

Conclusion

• The discovery contributes to our understanding of deep-sea biodiversity and the interconnectedness of marine ecosystems.
• It highlights the need for conservation efforts to protect these vulnerable ecosystems from environmental threats.
