Furnas et al. (2014) suggest that our conclusions are based upon limited sampling programs. However, we note that our principal conclusions, namely, (i) that hard coral cover in the Great Barrier Reef (GBR) has reduced by >70 % over the past century and (ii) that most GBR regions are characterized by Chl a values exceeding the defined chronic-eutrophic state (i.e., >0.2 mg m−3), are based on the extensive AIMS assembled data sets (e.g., see Fig. 3 in Bell et al. 2014).
Furnas et al. note that the ocean color data presented in Figs. 4 and 5, and in particular the data in the near-shore regions, do not represent accurate levels of Chl a. We generally agree with this assessment but note that we have not used these data in deriving the Eutrophication Threshold Model (ETM). We note that...
