Extended Data Fig. 6: Holocene tidal range change in the four study areas.
From: Sea-level rise at the end of the last deglaciation dominated by North American ice sheets
The modern data are from Admiralty Tide Tables, older data from paleotidal models. In the Mississippi and Rhine-Meuse deltas, the paleo-indicative range (IR) of samples older than 8 ka was calculated by increasing the present-day IR by a factor of 1.5. In the case of the Yangtze Delta and Malay Peninsula (including Singapore), for RSL samples older than 8 ka, we have increased the present-day IR by a factor of 1.5 to calculate the paleo-IR and by a factor of 1.1 for samples younger than 8 ka.
