Fragments of Pocillopora were dyed using alizarin dye and placed in-situ to grow. After 12 months, the corals were collected and cleaned by placing them in a plastic bag to allow the tissue to die/decompose. The dead tissue was washed off to reveal the coral skeleton. Colonies were labeled based on main branches and largest sub-branches. The collected coral were measured from the outside at the edge of the dye line to the top of the branch using digital calipers. Colonies were sawed apart by a diamond edge saw to reveal the inner dye line and measured from the dye line to the top of the branch using the same digital calipers.
