Temperature structure and variability in the NESAP from BGC-Argo floats and gridded products. a Brunt-Väisälä frequency (N2, s-2) over 0-100 m, highlighting stratification; the mixed layer depth (MLD) is overlaid in black (MLD defined by a 0.2 °C potential-temperature threshold). b Temperature anomaly (°C) from 0 to 1000 m relative to the 2004-2023 Argo gridded climatology; the diverging red–blue color scale is zero-centered (warm colors = positive anomalies, cool colors = negative anomalies). c Temperature at 50 m from three sources: BGC-Argo floats (blue triangles, monthly means with shaded ±1σ), Armor3D reanalysis (red line), and Argo gridded climatology (black line with black circles). d–f Time series of temperature anomaly (°C) at 50, 300, and 500 m from the Argo climatology; the red dashed line marks zero anomaly. Year ticks on the x-axes indicate calendar years. Statistical comparisons for panel (c) are reported in Table S1.
