Holocene reef-growth dynamics on Kodakara Island (29 degrees N, 129 degrees E) in the Northwest Pacific

摘要

The spatial distribution of modern coral reefs in the Northwest Pacific (NWP) is restricted to approximately 30 degrees N. Understanding the high-latitude reef-growth process and its correlation to climate change may provide important insights into future reef growth at even higher latitudes in response to global warming. We conducted field surveys and obtained seven cores from the raised reefs of Kodakara Island (29 degrees N, 129 degrees E) in the NWP to determine the changes in and response of reef growth dynamics to millennial-scale climate change through the Holocene. To reconstruct the timing of the reef growth, 37 coral ages were determined using accelerator mass spectrometry CAMS) radiocarbon dating.
