Oil spill off Live Firing Islands, 26 Jul 2016

About one ton of heavy fuel oil was spilled, affecting an area of about 20 nautical miles (37km). It happened just off southern Singapore in Malaysian waters. A report said "the vessel was boomed following the incident. The oil leak was stemmed quickly."

Mass coral bleaching at Sentosa, Tanjung Rimau

Mass coral bleaching is happening at Sentosa's natural shores at Tanjung Rimau.
There are not many hard corals on this shore. I estimate about 70% of the hard corals are bleaching. I saw a few small leathery soft corals and none of them were bleaching. But about 50% of the feathery soft corals with are abundant here are bleaching. I estimate 5-10% of the corals have died recently.

We estimate about 10-80% of the hard corals and 40-50% of the leathery soft corals are bleaching. We estimate 5-10% of the corals have died recently.

Seagrass meadows next to the Changi Boardwalk, with otter

This morning, a solo survey of Changi starting with a stretch that I've not surveyed before. This stretch is special because it has both rocky shores and seagrassy and sandy areas.
Today, the seagrasses were lush, with lots of sea cucumbers of various kinds. But some signs of distress among some cnidarians. I also had a glimpse of an otter. It saw me and disappeared into the water.
