Malaysian coral under threat: AlJazeera video clip

Al Jazeera's Stephanie Scawen has been investigating the effects on Malaysia's Tioman Island.

Bleaching in Indonesia leads to massive death on reefs

A survey of corals in Aceh, Indonesia revealed one of the most rapid and severe coral mortality events ever recorded. The scientists found that 80% of some species have died since the initial assessment and more colonies are expected to die within the next few months.
The Wildlife Conservation Society today released initial field observations that indicate that a dramatic rise in the surface temperature in Indonesian waters has resulted in a large-scale bleaching event that has devastated coral populations.

Bleaching in our Southern Islands: 28 May - 2 Jun 2010

Karenne Tun shared photos of bleaching at Pulau Hantu and Raffles Lighthouse on facebook.
Besides hard corals, even sea anemones were bleaching!

She said "Reminiscent of the 1998 bleaching event - but perhaps a shade less severe. Its still early days yet; Sea Surface Temperatures (SST) hovering around 31degC. Hoping that it will not get warmer than that. Did 2 surveys today - at Pulau Hantu and Raffles Lighthouse, to assess the severity of the bleaching. Working out potential recovery index now."
