Fig. 1: Empirical orthogonal function (EOF) spatial patterns.

Maps of the Empirical Orthogonal Function (EOF) spatial patterns of the first mode of a satellite observed sea surface height (SSH, m, regridded to the model grid), b modeled SSH (m), and model surface c salinity, d temperature (°C), e NO3 (μmol kg–1), f pCO2 (μatm), g saturation state for aragonite (Ωarag), and h pH calculated for the 1980−2013 period. The amount of variance associated with each EOF is shown at the lower-left corner of each map. The EOFs were computed based on the illustrated spatial domain and were applied to monthly model output after first removing a long-term temporal trend using a quadratic function and second deseasonalizing the data. A 100 km wide band along the coast has been masked out for surface salinity to avoid the interference of freshwater from the coastal river and glacial discharge with the EOF analysis.
