during mass coral bleaching in 2016. Despite the drastically reduced seagrass cover, it was nice to see many dugong feeding trails. The team also found Giant clams.
I surveyed the western end of Cyrene which is the most reefy part. I could see white patches of bleaching coral and leathery soft corals.
Jun 2016, about 80-90% of the hard corals and soft corals that I saw were bleaching. I last surveyed this reef in Jun 2019, when I did see some bleaching as well.
Here's a compilation of some of the hard corals I saw, with a ruler for further study by others.

I only saw one bleaching Frilly anemone. I saw many Asparagus flowery soft corals, most were orangey (rather their usual healthy purplish shades), but none were bleaching. Other cnidarians I saw were alright: other Frilly anemones, zoanthids, corallimorphs, Haddon's carpet anemone.
Horse mussels embedded in the sand. The shells were mostly empty and I saw a row of Reef murex snails that appeared to be feeding on them.
Fluted giant clams in several spots on the reef.
Although it lies in the middle of an industrial triangle and major shipping lanes, Cyrene has some of Singapore's most amazing shores. The 'star' of Cyrene used to be the many Knobbly sea stars that were commonly seen. Today, I only saw two. But the rest of the team saw more, scattered in other parts of Cyrene.
dugong feeding trails on the northern edge.
ongoing reclamation at Jurong Island might be affecting Cyrene.
