Morimoto, M., H. Kitagawa, Y. Shibata, and H. Kayanne. 2004. Seasonal radiocarbon variation of surface seawater recorded in a coral from Kikai Island, subtropical Northwestern Pacific. Radiocarbon 46(2):643-648.
A coral radiocarbon (D14C) investigation with a high time-resolution is crucial for reconstructing secular and seasonal D14C changes in the surface seawater, which potentially reflect ocean circulations and dynamic ocean-atmosphere interactions. The D14C values of a modern coral (Porites sp.) from Kikai Island, southern Japan, in the subtropical Northwestern Pacific, were determined for the period of 1991-1998 at a monthly resolution. A coral D14C time series for the 8 yr indicated seasonal cycles superimposed on a secular decreasing trend of 3.8 per mil.per yr. The seasonal amplitude of the coral D14C was about 18 per mil on the average, and minimum D14C was observed in late spring and summer. The D14C changes were tentatively explained by horizontal oceanic advections around Kikai Island or over the wide range of the equatorial and subequatorial Pacific.
