Don’t believe in climate change? Watch the corals. Over half of them have disappeared due to the increased oceanic temperatures. Pollution like sedimentation is affecting the reefs as well. However, some reefs are heroes and thrive under pressure. Our project focuses on such reefs in the Miri-Sibuti Coral Reefs National Park in Borneo. We will study the corals responses in different areas and through time to better understand their tolerance against sedimentation and temperature stress.
