Figure 4

Spatial distribution of the squared coherence at the dominant frequency mode of cross-spectra (shaded) and phase difference (vectors) between (a) sea level height (SLH) and averaged mangrove FCC for three dieback categories. (b) Gulf (Milner Bay) SLH and gridded SLH dataset, (c) IPO and SLH. Vectors pointing north represent no phase lag and the lag increases in the clockwise direction. The positive lag implies mangrove FCC lags SLH anomalies and vice versa. Plots are generated using the NCAR Command Language version 6.6.2 (http://www.ncl.ucar.edu/).
