(a) Map shows the extend of the 2 regions (i-north, ii-south) of the GBR used in this study (source: Project 3DGBR-eAtlas.org.au). (b) Background map shows the average rainfall annual distribution based on 30-year records (1961–1990) encompassing several ENSO events (7 El Niño - 5 La Niña) (source: Bureau of Meteorology). White lines highlight precipitation 0.5 m/a contours. Red arrows define prevailing annual offshore wave directions scaled based on their annual activity. Wave heights (H) imposed for the considered 2 climatic scenarios from 14 to 5 ka and from 5 ka to present. Both maps were generated using Paraview (V 5.2.0).
