Image by Dr. Andy Bruckner, Global Reef Expedition. By Andrew Bruckner, Ph.D. Global Reef Expedition Fiji\u2019s reefs house some 333 species of corals of all shapes, sizes and colors, many of which we\u2019ve seen in Lau Province.\u00a0 We\u2019ve examined many reef types, some which fringe the shore (fringing reefs), some in the center of a lagoon (lagoonal patch reefs), and some that form a barrier between the open ocean and the lagoon (barrier reefs).\u00a0 We\u2019ve also surveyed different habitats within these reefs \u2013 the reef flat, reef crest, pinnacles and coral bommies, fore reef slope and lagoonal floor, from about 30 meters (m) depth to just below the water\u2019s surface.

For each survey, we record the type of coral, how much of the bottom is covered by each coral, the sizes of the corals, and their\u00a0health, within a defined area (10 m belt transect).\u00a0\u00a0 What\u2019s remarkable is how vastly different the reefs are on each island and sometimes between reefs within an island.\u00a0 After nine islands, we continue to add new corals to our species list and often come up from a dive in awe of what we\u2019ve witnessed. Some species, such as the magnificent bubble coral (Plerogyra sinuosa), whose surface covered\u00a0in translucent grape-like bubbles by day and elongate, deadly tentacles by night (well, not to a human, but extremely painful if you accidentally run into them), we\u2019ve seen just once.\u00a0 Other corals, such as the large table-forming corals in the genus\u00a0Acropora\u00a0(acroporids) are found everywhere.\u00a0 They often form multiple canopy layers, towering above other corals and covering much of the bottom.\u00a0 Nevertheless, these tables (and other acroporids such as the staghorn corals) consist of more than 150 different species, each with different patterns of branching, different skeletal structures, and highly variable coloration. Huge Merulina sp. colony in Fiji. Image by Dr. Andy Bruckner. The state of the corals also varies from one reef to the next. We\u2019ve seen reefs with nearly 100% of the bottom covered by coral and others with few corals.\u00a0 Also, the size of individual colonies can vary from just a few centimeters to over 5 m (e.g.\u00a0Diploastrea).\u00a0 Because we have no way of knowing the exact age of a coral, we measure their sizes \u2013 this is a proxy for age which provides useful information on the past history and possibly future trajectories of a coral reef. For instance a reef with only small corals is likely to have been severely damaged but is recovering, whereas a reef with only large corals may have had a long history without disturbance.\u00a0 An assessment of coral condition (e.g. health) provides further information necessary to understand possible causes of damage or threats, and can help predict the future fate of that reef.\u00a0 So how healthy are the corals of Lau Province?\u00a0 Check back\u00a0tomorrow\u00a0to find\u00a0out.

 Fiji’s reefs house some 333 species of corals of all shapes, sizes and colors, many of which we’ve seen in Lau Province.  We’ve examined many reef types, some which fringe the shore (fringing reefs), some in the center of a lagoon (lagoonal patch reefs), and some that form a barrier between the open ocean and the lagoon (barrier reefs).  We’ve also surveyed different habitats within these reefs – the reef flat, reef crest, pinnacles and coral bommies, fore reef slope and lagoonal floor, from about 30 meters (m) depth to just below the water’s surface.  MORE: Global Reef Expedition: Canopies of Coral
