Anderson Mayfield photographing a pale branch of the Cauliflower coral, Pocillopora verrucosa, that he is about to take a small sample from for later analysis which may lead to an answer as to why this portion of the colony had lost their algal symbionts and bleached.
Lauren Valentino operates a pneumatic hand drill powered by a scuba tank to use a diamond tipped hole saw to extract sample corals from Porites lobata colonies. The cores are later sliced thinly and imaged with a CAT scanner to count the growth bands determining the growth rate of the colony.
