I'm sorry but I'm not sure I follow. Are you suggesting that the nutrients that get washed out via catchments in NSW end up on the GBR? I didn't realise this. Certainly water quality is a massive issue, and the current mess going on in the Murray-Darling is highly concerning in a general way. Also regards the nutrients, yes we have exactly the same issue with e.g. sugar, bananas, graziers up here.
- boffinAudio 4y agoThe issue is that we've screwed with the water systems in the region so much, that when there is a flood event in areas that have had their natural water flows completely altered, nutrients that have built up in the system that would normally 'trickle-release' slowly are instead dumped en mass into our ocean. Don't forget that for 9 months of the year, the ocean water currents draw waters from the southern coast towards the north... reversing during summer (drought), but when the rainy season hits, and washes the stored nutrients out, the currents pull that artificially nutrient-rich waters directly onto the reef. Its a mess of epic proportions, but unfortunately the cotton profits are too damned high.
