Spheroidal carbonaceous particles (SCPs) are carbonaceous fly ash particles produced exclusively by industrial fossil fuel combustion. We examined the SCP record in Beppu Bay sediments in southern Japan, and compared this record with historical trends in industrial activity and monitoring data for atmospheric pollution in the region. Beppu Bay has varved sediments in the absence of bioturbation, providing an ideal situation for SCP study. Our results show that the temporal variation of SCP deposition is consistent with the trends of industrial activity and the temporal variation of atmospheric pollution status. We conclude that undisturbed sediments, such as the Beppu Bay sediments, have SCP records that adequately represent the historical trends of industrial activity and atmospheric pollution in detail. These results support that SCPs are a potential marker for the Anthropocene characterized by industrialization.
