Figure 45 The time series of aragonite saturation (ΩAr) in the period 2012 to 2020 in the Atlantic Water (salinity 34.9, temperature 0 C). The linear regression fit (orange line; gradient = 0.0250 0.0086, p = 0.0234, R2 = 0.54) is based on annual mean pH values (black squares) from observational data (circles). Bars are 1 standard deviation for each annual mean. The grey shaded area represents the 95% confidence limits.
