Abstract: Coral reefs are currently facing multiple disturbances caused by natural/anthropogenic factors. Recent industrial development might influence reef environments and ecosystems; however, few direct comparisons of coral calcification with the histories of local industries exist. We show the coral Ba/Ca record and growth histories for 46 years collected from Sumiyo Bay, Amami-Oshima Island, Japan. Coral Ba/Ca was mainly controlled by the sediment loads in seawater, which are introduced through the two local rivers. Coral Ba/Ca records have been characterized by two distinct historical periods: the decadal fluctuation corresponding to the traditional silk fabric industry (1960s similar to 1995) and the increasing trend corresponding to the development of quarries and the construction industry (1996 similar to). Coral Ba/Ca records and local industrial histories were also linked to coral calcification. A long-term quantitative assessment of reef environments and local industrial changes could provide an evaluation of the survival strategies of reef-building corals in the future.
