Thank you for taking the time to take our survey. We are working on our ability to detect coral bleaching and turbidity using high-resolution (3.7m) satellite imagery. You will see us use the term 'coral bleaching' throughout this survey, but please note we are referring to a change in color in a pixel, and therefore it is really an indication of 'brightening'. Though we cannot be certain that the pixel brightening represents a true bleaching, we hope this indication can focus your attention to where bleaching is most likely occurring.
