Coral reefs are sensitive to climate change and have a direct correlation to sea level. New observations show that an extensive coral reef existed in the southern Pacific Ocean thousands of years ago. Woodroffe et al. used multibeam sonar, coring, and dating to examine a relict reef discovered in water about 20–25 meters deep around Lord Howe Island in the southern Pacific Ocean.
