a Interglacial periods and b glacial periods. Glacial–interglacial (GIG)-1, GIG-2, GIG-3, and GIG-4 represent marine isotope stage (MIS) 1/2, MIS 5/6, MIS 7/8, and MIS 9/10, respectively. The four interglacials are defined as 0–5, 125–130, 240–243, and 333–337 kyr in accordance with the periods of precession maxima, and the four glacials are defined as 19–23, 132–139, 252–256, and 338–343 kyr in accordance with the periods of precession minima. Diagonals represent isopycnal surfaces (kg m−3). The colored shading represents the main distribution range of the water temperature–salinity data at each core site, and the closed contour lines are defined as the median of two boundary points.
