Update on coral bleaching at Sultan Shoal (Aug 2014)

The Maritime and Port Authority of Singapore (MPA) has been relocating corals at Sultan Shoal as part of their preventive measures to protect the corals from the development works for the future Tuas Terminal and DHI was engaged to carry out the relocation works.
Recently, MPA has updated its NGO partners on the observations of coral bleaching at Sultan Shoal.

During the week of 28 July, DHI Singapore observed that the bleaching situation at Sultan Shoal and Sisters’ Island continues to remain largely unchanged. As reflected by the declining temperatures recorded in the southern waters, we are starting to see some cooling from peak SST anomalies across the South China Sea.

If the El Nino event continues to develop as predicted, we should continue to see our water temperatures start to stabilize below 30°C and hopefully, that will result in some actual recovery in the bleached corals in the coming months. DHI and MPA will continue to monitor the health of the corals at Sultan Shoal and the health of the transplanted corals at Sisters’ Islands.
