Live and work on the GBR, for a reef non-profit. Should be noted the mass bleachings were 16/17 and unprecendented in scale and frequency. We fortunately havent had any events of this magnitude since. Huge amount of work being done, but should be noted the only real solution involves tackling climate change. There are a whole bunch of interesting coral restoration projects happening on the GBR right now with some new ones (with unique methodologies) kicking off soon. We work with a bunch of them here @citizensGBR, including the 'larval restoration project' which is a collaboration between a number of universities and other conservation-focussed orgs.
