Additional file 1. Spectra analysis based on fast Fourier transform method. Figure S1. Spatial and temporal coverage of in-situ and GRACE data. (a) Spatial locations of 46 CPIES from cDrake experiment. Black triangles: C line; white triangles: Local Dynamics Array (including A, B, D, E, F and G arrays); magenta triangles: H array. (b) GRACE grid point positions. Red dots: spherical harmonics products from CSR, JPL and GFZ; green dots: JPL and GSFC mascon product; black dots: CSR mascon product. (c) Daily-mean ocean bottom pressure records from 46 CPIES. The x-axis represents the day number, while the y-axis represents the different stations, labeled as A1, A2, A3, B1, B2, B3, and so on. Black shaded areas indicate missing values.Figure S2. Variance-preserved power spectra as a function of period. (a) OBP and (b&c) bottom current velocities in the LDA region. Red lines denote 95% confidence levels.Figure S3. Correlation coefficients between eddy kinetic energy (EKE) calculated from AVISO geostrophic ...
