Shelf-scale budgets were developed for the nutrient elements nitrogen (N) and phosphorus (P)
in the central Great Barrier Reef between Cape Tribulation (I 60 S} and Dunk Island (ca. 18°S).
The intent was to quantify:
I} stocks of nutrients (nitrogen (N). phosphorus (P) and silicon (Si}) naturally
occurring in central Great Barrier Reef waters;
2) natural gradients and variability in water column nutrient concentrations;
3} natural fluxes of nutrients into and out of shelf waters for comparison with
anthropogenic or anthropogenically affected nutrient sources
