Some Effects of Subsea Water Pipeline Construction on Sessile Benthic Community Structure of Redang Island, Malaysia

A pipeline system, constructed in 1997- 1998, to provide water to Redang Island, traverses an area covered with coral reefs. Biological studies were conducted before and following the construction to monitor changes in habitat and biota at selected sites. Pre-construction studies consisted of con...
