Methodology:
Corals were surveyed for bleaching during 10 minute timed swims by snorkelers. During the 10 min survey snorkelers counted every coral colony and scored the colony as being bleached or not. The number of corals dead from bleaching were also counted (parameter "percent mortality"). Data are expressed as the percentage of the total colonies that were bleached or dead from bleaching.

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* rounded LATITUDE and LONGITUDE to 5 decimal places.
* renamed column "DATE" to "DAY" as it contained the day.
* added "DATE" column containing date in ISO 8601 format YYYY-mm-dd
