Impacted by chemical spill on 9 Jan at Pulau Bukom?
Last week, it was reported that on 9 Jan, the leak happened in a Shell unit on Pulau Bukom that was already shut down for maintenance. Shell said "there is no adverse impact expected in the water or the surroundings" as a result of the leak. When asked about what chemical was leaked, Shell said it does not provide such details "for reasons of commercial confidentiality". "The cause of the leak is being investigated," its spokesperson added. "The safety of the community and our personnel, as well as the protection of the environment, remain our top priority."
Today, I noticed yellowing leaves on the two large Perepat mangrove trees growing on Pulau Hantu. In one of the trees, half of the tree appears to be bare of leaves.
Api-api pasir trees nearby had some yellow leaves but normal looking flower buds and seedlings.
Impact of huge barges 'parked' in western lagoon in Oct 2016?
I decided to check the Western lagoon where two huge barges were seen 'parked' inside in Oct 2016. Barges require tugboats to be moved around. I find it hard to believe the barges ended up in the lagoon by accident. Particularly since the opening of the lagoon is only about 90m and the barges are estimated to be 50m long.

Impact of mass coral bleaching since mid-2016?
We didn't get a chance to visit Pulau Hantu at the height of mass coral bleaching. But we did see mass coral bleaching at nearby Terumbu Hantu in Jun 2016. About 60-70% of the hard corals and soft corals that I saw were bleaching.

Merulinid corals. Most were not bleaching, but had large dead patches.
Flowery disk corals. One was pale, another had dead patches.
Anemone corals, one was alright but had large dead patches, the other was still rather bleachy.
Galaxy coral, Brain coral, Lettuce corals and Acropora corals. Also some small clumps of Branching Montipora corals.
Fire anemones in the sandy lagoon.
Russel Low surveyed the reef edge of Pulau Hantu and saw lots of healthy corals. What a relief!

While the Tape seagrasses in the Northern lagoon were nice and long, I saw a few cropped Tape seagrasses in the Western lagoon. There were also sprinkles of Spoons seagrass with small leaf blades, heavily covered in epiphytes. I didn't see any flowering seagrasses. My last trip here was in Aug 2015.
