Decline in the Acropora population due to repeated moderate disturbances in Okinotorishima Island, Japan

Okinotorishima Island, an isolated remote table reef island in the southernmost territory of Japan, provides an excellent site to examine the effect of only global stress, as there are no local human stresses present. Yamamoto et al. (2023) established 17 fixed quadrats (1×1 meter) on 9 knolls in the shallow lagoon of Okinotorishima Island, and observed coral population every May from 2006 to 2015. This dataset compiles data on coverage and number of colonies of Acropora and co-occurring corals published in Yamamoto et al. (2023). Yamamoto, H., Kawasaki, T., Tamura, K., Kanyama, T.
