Coral reef benthic and fish surveys in the Chagos Archipelago

Surveys of 18 reef sites around the northern atolls of the Chagos Archipelago, British Indian Ocean Territory. Benthic cover of corals and other organisms were quantified along with the abundance diversity and size of reef associated fishes.

      These surveys were conducted in 2010 by Nick Graham and Morgan Pratchett of James Cook University. At each of the 18 sites 4 replicate 50m transects were surveyed at both 9m and 3m depth. Coral and other benthic cover were surveyed using point intercept methodology, while fish were surveyed using 50*5m belt transect UVC. The location has been largely unfished and uninhabited since the early 1970’s. The data are being used to make comparisons to other reef systems across the Indian Ocean to assess this fairly pristine site to more degraded reefs elsewhere.
