Figure 3 a) Bathymetry map of Northern Indian Ocean Basin with LNLC regions. Edge of continental shelf at 200m is marked in
purple. 3000 m depth contour is marked in white. LNLC regions are marked in Arabian Sea (green patch) and Bay of Bengal (red
patch) b) Minimum inter annual variability in the LNLC areas.
Spatial anomaly index computed by the method described earlier indicates the chlorophyll values in the LNLC
regions to be below (-0.5) the climatic basin scale means (Figure 4).
