Fig 6. Autocorrelation of chlorophyll over time and across time scales.

Panels A,F, and K indicate the autocorrelation (color) of the time series across time scales (vertical axis) through time (horizontal axis). Autocorrelation was computed by calculating the autocorrelation function in a rolling window (see Methods). Panel K is produced by subtracting Panel A from Panel F. Each of the time series panels to the left indicates autocorrelation dynamics at a single time scale. These panels use the same horizontal axis as panels A,F, and K, but represent autocorrelation on the vertical axis instead of as a blue-white-red color gradient.
