“…In Osaka Bay and Plain (core OB‐1, W1, W2, and Bor.1), Iyonada (core K1, K2, S1, and S2), and Hiroshima Bay (core HIR94‐3), 190 out of 213 samples are analogous (Figure S6). Irizuki et al (2001) and Yasuhara et al (2004, 2005), and Yasuhara and Seto (2006), who studied ostracode assemblages with a focus on the ecology of dominant taxa and inferred paleo‐water depths, have inferred RSL changes from cores collected in core OB‐1, K1, K2, S1, S2, and HIR94‐3. In core K1 and K2, the results of RSL are concordant with Yasuhara et al (2005), considering the errors.…”
