a The plot of intraseasonal equivalent water depth at the BPR-MC (solid red; 117.94°E, 15.02°S, 5664 m) and the BPR-PAC (solid blue; 176.32°E, 9.517°S, 4921 m) during each December–April from 2009 to 2019. b Correlation (>90% significance; see methods section) of intraseasonal equivalent water depth from bottom pressure recorders across the globe with respect to the intraseasonal equivalent water depth at the BPR-MC (red box). All other bottom pressure recorders are marked as solid circles. The blue square box is used to mark BPR-PAC. The background color shades represent the bathymetry. The number of bottom pressure recorders analyzed in the Indian Ocean, Pacific Ocean, Atlantic Ocean, and the Arctic Ocean are 8, 45, 23, and 6, respectively.
