Fig. 5: Responses of precipitation δ18O (δ18Op) to East Asia (EA) shelf area inundation and comparison with reconstructions.

From: Continental shelf area inundation drove reduced temperature seasonality in East Asia during the last deglaciation

Fig. 5

a Simulated δ18Op responses (vSMOW, Vienna Standard Mean Ocean Water, 1‰) to East Asia (EA) continental shelf area inundation. Green triangles denote the locations of proxies. Dotted areas exceed the 90% confidence level based on the two-tailed Student’s t test. b Reconstructed δ18O from cave records (δ18Oc, vPDB, Vienna PeeDee Belemnite, 1‰). The red, orange, green, blue lines denote records from Hulu34, Sanbao35, Haozhu36, Dongge cave37, respectively. Gray solid line is the ensemble mean of four cave records, while the gray dashed line represents its trend. Red stars represent the regional averaged simulated δ18Oc (vPDB, 1‰) in the EA (20°‒45° N, 100°‒130° E) responses to EA continental shelf area inundation.
