Coral Breakage due to Hurricane Iselle
The storm surge created by Hurricane Iselle physically fragmented some coral colonies. The coral breakage was restricted to the northern part of Waiʻōpae Tide Pools (outside of the Marine Life Conservation District) where up to 18% of coral colonies were broken, depending on the species (Figure 1). Cauliflower corals with long slender branches were especially vulnerable (Figure 2). Inside of the MLCD saw no coral breakage.
