Long-Term Relationships between the Marine Environment, Krill and Salps in the Southern Ocean
Figure 15
The wavelet cross-spectrum (a, b) and coherency spectrum (c, d) between the SOI and water temperature at 0 m and 100 m. The vectors indicate the phase difference between the SOI and water temperature (with in-phase pointing right, antiphase pointing left, an arrow pointing vertically means the second time series lags the first by 90°, that is, the phase angle is 270°. The 5% significance level against red noise is shown as a tick contour, and the thin black line indicates the cone of the influence.
