Q2. Discuss the role of ocean currents and temperature anomalies in influencing the frequency and intensity of coral bleaching events in tropical regions. (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question: The southern Great Barrier Reef (GBR) saw catastrophic coral bleaching in May 2024, with a staggering 44 per cent mortality rate in protected areas, triggered by heat stress during one of the largest bleaching events recorded Key demand of the question: The question requires an analysis of how ocean currents and temperature anomalies contribute to coral bleaching events, and an exploration of their impact on the frequency and intensity of bleaching in tropical regions. Structure of the Answer: Introduction: Introduce the phenomenon of coral bleaching and its dependence on oceanic factors, emphasizing the significance of ocean currents and temperature anomalies in shaping coral health. Body: Role of ocean currents in coral bleaching: Discuss how ocean currents regulate temperature, nutrient distribution, and stress levels in tropical coral ecosystems. Impact of temperature anomalies: Explain how variations in sea surface temperature due to climate phenomena like El Niño and marine heatwaves contribute to coral stress and mortality. Conclusion: Conclude by stressing the need for global climate action and local conservation measures to enhance coral reef resilience and mitigate the adverse effects of oceanic changes.Bottom of Form
