Time series of de-seasoned Mixed-Layer Depth (MLD) data at BATS computed from CTD sensor temperature profiles included in the study (Methods). Solid orange line: de-seasoned MLD data. Dashed black line: is the linear regression applied to the entire de-seasoned MLD time series (1990–2022). Dashed purple line is the linear regression fitted to de-seasoned MLD up to the end of 2010 (Pre-2011; 1990–2010). Dashed red line is the linear regressions fitted to de-seasoned MLD only from 2011 up to the end of 2022 (Post-2011; 2011–2022). P = significance of the trends via Pearson correlation. See Data Analysis for extracting deseasonalised data and for details on the linear trend analysis (Methods). See Extended Data Fig. 7d for MLD time series.
