Comment:
Plateau No. 1 - 3: By comparison with Suigetsu Plateau 3 the short length of Plateau 3 may be explained by a ~200-yr drop in local 14C reservoir age over Plateau 3. Its actual range,156.5-160.5 cm, is given by a dotted line in Fig. 2.
Plateau No. 4 -6a: Below Plateau 6a a 14C jump of 2000 yr reflects a hiatus at 210-212 cm depth on top of sediments older than Plateau 7 (23 cal. ka).
