| Abstract |
Using a combination of remote sensing (aerial photographic) and geochemical (coral annual band) data, we detected significant increases in sediment and nutrient discharge in response to land development during the past 50 years on Ishigaki Island, Southwest Japan. Correlates of coral reef decline were also detected using remote sensing (aerial photographic) data. Given that historical aerial photographs are available for many areas from as early as the 1900s and that long-lived corals can record paleoenvironmental conditions for more than 100 years, our approach could be applied to reconstructing changes in other coral reef regions worldwide since the early twentieth century or before. |
