Figure 7

Left panel: Squared wavelet coherence (colour) and phase (arrows) between polyp activity \(({{\boldsymbol{\gamma }}{\boldsymbol{^{\prime} }}}_{{\boldsymbol{t}}})\) and the northward component of the bottom current velocity \(({{\boldsymbol{x}}}_{{\boldsymbol{t}}}^{{({\boldsymbol{Vn}}1)}^{{\boldsymbol{\text{'}}}}})\). A value of 1 would indicate a perfect coherence, while a value of 0 would indicate no coherence. Significant coherence is indicated by the black contour lines (Monte Carlo test, 95% significance level). Right panel: The corresponding scale-averaged coherence over the entire measurement period.
