Q U E E N S L A N D Princess Charlotte Bay Notes on surveys: Since 1 December 2015, over 1400 in-water surveys of 124 reefs have been conducted. Since 1 February 2016, when the high-risk period of bleaching commenced, over 950 in-water surveys have been conducted on 92 reefs. To fully assess coral condition, at least nine different sites on each coral reef are surveyed. This allows surveys to take into account natural variability such as wave action, depth and different reef habitat.
