Abstract: Coral reefs have suffered from a range of impacts from local anthropogenic influence to global climate change. These changes adversely affected to switch coral dominated reefs systems to algae dominated systems. However the mechanisms related to these global changes in coral reefs is not well understood to date. We hypothesis that microbial activity in reef waters could be a possible lower scale indication to explain mechanisms related to global change in coral reefs. Reef benthic monitoring, water chemistry (Dissolved Organic Carbon - DOC) and higher Dissolved Inorganic Nitrogen - DIN) and abundance of microorganisms (Bacteria and Virus) performed 08 coral reef sites around Sri Lanka from February 2014 to April 2015. Results show that the coral reefs in north are dominated by living corals whereas reefs in south dominated by algae. Algal dominant reefs represented by higher microbial abundances with relation to lower concentrations of DOC and higher DIN. These results suggest that potential connectivity to changes of reef systems with the microbial activity. Further analyses are in progress to explain how microbes structuring reef in Sri Lanka
Summary: This data set is presented from Sri Lankan coral reefs, Indian Ocean performed from 2015 -2016. Special attention was given for the water chemistry and microbial abundance in water column of reef systems around Sri Lanka addition to benthic assessmentsReferences: Global microbialization of coral reefs
