This is a station for the Great Barrier Reef.
QuickSilver will dock on this station. The station is held in place in 30 feet of water by chains anchored in very big concrete blocks which lie on the ocean floor. On arriving, we were given lunch and told about how to proceed to see that part of the local reef. We could snorkel, scuba, walk down some stairs and gaze thought some under water windows or take a ride in a submarine like vehicle with windows.
