They talked about that in the article. The lagoon-like nature of the reef apparently means there are reduced currents.

- crazygringo 3y agoAh thank you -- somehow I missed that part. Quoting: > “It’s an average of about 30 or 40 meters deep; it’s very shallow. It’s a huge lagoon where the circulation with the Pacific Ocean is very much cut off. So water exchanges slowly through these 3,000-and-something reefs. The reason that cloud brightening can work for the Great Barrier Reef is that you’ve got all of this water trapped here.”
- steve_adams_86 3y agoThis must be part of how the water can be so incredibly clear here. Where I live, a lot of the turbidity of the water results from marine debris being picked up by heavy tidal movement. We get clear waters occasionally, but it’s typically in the darker periods of the year (winter) when tides are relatively calm. This means less algae and less debris moving around. It makes for stunning diving opportunities, but it’s extremely cold and perfect visibility (by our standards) is pretty rare.
