Summary of the process followed to build plume water maps with examples of inputs and outputs. (a) Plume mapping process: different shadings represent steps (light gray), analyses within steps (white), intermediate outputs (dark gray), and final outputs (black) (modified from Álvarez-Romero et al. 2013). (b) A: Aqua MODIS true-colour image used to create the spectral signatures defining six colour classes for GBR plumes (25/01/2011) and B: weekly composite (19 to 25/01/2011) of six-class map (modified from Álvarez-Romero et al. 2013); C: weekly surface water plume map; D: reclassified map into weekly primary (P), secondary (S), and tertiary (T) composite (19 to 25/01/2011); E: frequency of occurrence of the secondary water type in 2011; F: multi-annual (2007–2012) frequency of occurrence of the secondary water type. Panels C–F are zoomed into the Tully-Burdekin area (see red box on panel B).
