Extended Data Fig. 2: Sea surface salinity trend in observation-based datasets and climate model.
From: Hydrological cycle amplification reshapes warming-driven oxygen loss in the Atlantic Ocean
Stippling in each panel indicates that the trend is not significant at the 95% confidence level. Datasets are as follows: ECMWF’s reanalysis ORAS54, National Center for Environmental Information’s objective analysis Levitus5, Japanese Meteorological Agency’s objective analysis Ishii6, UK-Hadley Centre’s objective analysis EN47, and Institute for Atmospheric Physics’ objective analysis CZ168. The final, lowest right, panel shows the 200-year trend in the ESM2M 1%-to-doubling experiment used in this study. Black contours show water masses according to density and salinity criteria outlined in Methods section, using the mean density and salinity in each dataset (for Levitus, the World Ocean Atlas 2018 dataset is used). Area south of 60◦S has been removed.
