The team has already started looking closer at these remarkable features of the land-ocean continuum. On the one hand, we have developed a working typology for reef passages, employing GIS-based visual interpretations of satellite imagery across nine Pacific Islands (in Fiji, New Caledonia, and Vanuatu). On the other, drawing from qualitative interviews with fishers, scuba divers, and surfers in New Caledonia, we have illustrated that reef passages can play a multitude of socio-cultural and ecological roles for the islands and Islanders.
