Sedimentation on Pulau Hantu Reef Slope

Date July 29, 2012

In the previous post, we shared how a section of Hantu Island’s reef slope has succumbed to the impact of sedimentation. Just three years ago, this part of the reef was alive with Goniopora coral, as the picture below shows.

Today it is covered in silt, algae and strings of mucous from the stressed corals, with a few small colonies of coral between the rubble.

There is no comprehensive study to determine how and why this has occured on this section on the reef, and why the impact has been so dramatic over the past three years.
