Fig. 5 Comparison of stable nitrogen isotope records for 50 ka sediments in different types of seas (modified after references [69,88]） Cariaco basin (blue) sediments δ15Nbulk[79]; Arabian sea (brown red) sediments δ15Nbulk[19] The South China Sea sediments δ15Nbulk (black)[86] and FB-δ15N (green)[89]. The shaded part is the interglacial period, and the figure is the Marine Isotope Stage(MIS)
