¹Lagoon width measured in Google earth, classifications based on those of Rongo and van Woesik [35]: Lagoon width <200 m=Narrow; 200 m<lagoon width <400 m=Intermediate; lagoon width >400 m=Wide.

²Wind exposure based on the dominant south easterly wind direction [43] and consistent with that used by Rongo and van Woesik [35].
