Although widely quoted, Smith’s 1978 figure of 600 000 km2 is only an approximate calculation. The World Conservation Monitoring Centre has prepared a new estimate of reef coverage by mapping emergent reef crest and very shallow reef systems. These data were rasterised, using 1 km grid squares, as a means of reducing errors arising… CONTINUE READING
