Annual-mean, globally-integrated energy and mass budget terms for the ACCESS-CM2 pre-industrial control experiment. The time series in panels (a), (b) and (c) represent the anomaly with respect to the first year, while the de-drifted time series in panels (d), (e) and (f) were calculated by fitting and then subtracting a cubic polynomial from the corresponding time series in panels (a), (b) and (c). Ocean salinity was converted to an equivalent change in ocean mass as per Equation \ref{eq:salinity} and a ten-year running mean was applied to the de-drifted time series.
