The process of coral bleaching in the Indian Ocean is most directly linked to:

1. Anthropogenically induced sea surface temperature increases
2. Increased deep-sea mining
3. Increased levels of ocean acidification from river runoff
4. The effects of increased Arctic ice melt

Correct answer: Anthropogenically induced sea surface temperature increases

Solution

Coral bleaching is primarily caused by elevated sea surface temperatures, which stress corals and lead them to expel their symbiotic algae. Human-induced warming is the main direct driver in the Indian Ocean.
