Summary of spatial and temporal patterns of surface and hydrographic conditions in the Northwestern Patagonia coastal system. Each row of maps shows a different variable: sea surface temperature (a–d), the turbidity proxy R645 (e–h), and the halocline depth (i–d) corresponding to the depth of maximum salinity gradient. Columns show the long-term means (a, e, i), the amplitude of the seasonal signal (b, f, j), the non-seasonal variability or residual variance (c, g, k), and statistically significant interannual trends (d, h, l). Data from MODIS-Aqua monthly composites (SST and R645; 2003–2022) and the Copernicus GLORYS12V1 reanalysis (salinity profiles 1993–2021). Panels d, h, and l show only the pixels with significant (α = 0.05) negative (blue) and positive (red) trends.
