Figure 3: Centennial and multidecadal variability of the Labrador Sea algal time series 1365–2007.

(a) The full time series (black curve) with the SSA reconstruction that retains variability on centennial time scales in red. (b) The full time series (black curve) with the SSA reconstruction that retains variability on centennial and multidecadal time scales in red. (c) The SSA reconstruction that retains the multidecadal mode of variability with measures of the standard deviation in this mode before and after 1825 indicated by the blue and red lines respectively.
